According to a Reuters, despite the U.S. expanding export controls on advanced artificial intelligence (AI) chips to China last year, Chinese universities and research institutions have recently acquired high-end AI chips from Nvidia through distributors.

Reviewing hundreds of bidding documents, Reuters found that since the U.S. expanded chip export controls on November 17 last year, ten Chinese entities have acquired Nvidia’s advanced chips embedded in server products produced by U.S. firms Supermicro, Dell, and Taiwanese company Gigabyte Technology.

Based on this Reuters report, bidding documents not reported from November 20 last year to February 28 this year show that Chinese institutions such as the Chinese Academy of Sciences, Shandong Artificial Intelligence Institute, Hubei Earthquake Administration, Shandong University, Southwest University, a technology investment company owned by the Heilongjiang Provincial Government, a state-owned aerospace research center, and a space science center have purchased these server products from distributors, which include some of Nvidia’s most advanced chips.

In response, a Nvidia spokesperson told Reuters that the products involved in these bids were exported before the ban was implemented in the United States. The spokesperson stated that the report does not imply that Nvidia or any of its partners violated export control regulations, and the proportion of these products in global sales is negligible. Nvidia complies with U.S. regulatory standards.

Both Supermicro and Dell stated that they would investigate and take action if any third-party illegal exports or re-exports are found. Gigabyte, the Taiwanese company mentioned in the report, told the Central News Agency that it has fully complied with relevant regulations since the chip ban took effect on November 17 last year, and has not shipped any restricted products to China. Gigabyte reiterated its strict adherence to relevant Taiwanese laws and international embargo regulations, stating that there has been no violation of any embargo regulations.

In 2023, the United States further restricted Chinese businesses from acquiring high-end AI chips. At that time, Nvidia responded by launching a China-specific version, the H20. TrendForce also presented relevant data for the Chinese market, indicating that Chinese CSP companies, including ByteDance, Baidu, Alibaba, and Tencent (BBAT), accounted for approximately 6.3% of high-end AI server shipments in 2023. Considering the ban and subsequent risks, it is estimated that the proportion in 2024 may be less than 4%.

As the Apple Worldwide Developers Conference (WWDC) in June approaches, recent rumors about Apple’s AI research have resurfaced. According to reports from MacRumors and Tom’s Guide, Apple is reportedly developing a large language model (LLM) comparable to ChatGPT that can run directly on devices without relying on cloud platforms.

In late February of this year, Apple reportedly decided to terminate its electric car development project “Project Titan” initiated a decade ago and redirected research funds and resources into the field of generative AI. This move has drawn significant attention to Apple’s activities in the AI sector.

Moreover, MacRumors also reports that Apple’s AI research team, led by John Giannandrea, began developing a conversational AI software, known today as a large language model, four years ago. It is understood that Apple’s proprietary large language model has been trained with over 200 billion parameters, making it more powerful than ChatGPT 3.5.

Previously, Apple disclosed that the iOS 18 operating system, set to launch this year, will incorporate AI capabilities. Recently, tech website Tom’s Guide speculated further that iOS 18 could execute large language models directly on Apple devices. However, whether Apple’s large language model can be successfully integrated into various Apple software services remains to be seen.

Using Apple’s voice assistant Siri as an example, at an AI summit held by Apple in February last year, employees were informed that Siri would integrate a large language model in the future. However, former Siri engineer John Burkey revealed to The New York Times that Siri’s programming is quite complex, requiring six weeks to rebuild the database for each new sentence added.

On the other hand, amid Apple’s AI research facing challenges, interest in its Vision Pro headset device has also begun to wane, with recent sales cooling rapidly. As per a report by Mark Gurman from Bloomberg, he has indicated that demands for Vision Pro demos are way down at Apple stores, and sales of Vision Pro at some stores have dropped from a few units per day to a few units per week.

• With the Ongoing Expansion of Global EV Battery Market, China’s Dominant Position Steadily Strengthens

In recent years, the rapid growth of EV and energy storage markets has driven robust demand for lithium-ion batteries (LiBs). Data shows that in 2023, the total shipment of LiBs exceeded 1 terawatt-hour (TWh) for the first time, with the market size growing more than tenfold compared to 2015, and EV battery shipment accounted for over 70% of the general battery shipment.

As the electric vehicle and energy storage markets continue to grow, the demand for LiBs will enjoy further expansion, with global LiBs shipment expected to outstrip 3,200 GWh by 2027.

Despite the fact that LiB was initially commercialized in Japan in the 1990s and long dominated by Japanese and South Korean manufacturers, over two decades later, China has leapfrogged the two nations. Currently, over 75% of the world’s LiBs are produced in China, marking China’s top position in manufacturing LiB.

Likewise, in the EV battery sector, which accounts for the largest demand in the LiB market, six out of the top ten manufacturers globally are headquartered in China, including CATL, BYD, CALB, Gotion High-Tech, EVE Energy, and Sunwoda, which are expected to hold increasingly higher market shares while the market shares of Japanese and South Korean companies is declining year by year.

For instance, Panasonic’s market share in the EV battery market has dropped to around 6%, and the combined market share of South Korean manufacturers to approximately 23%.

However, with the advancement and breakthroughs in next-generation automotive battery technology—all-solid-state battery (ASSB) technology—the position of traditional liquid-state battery is being challenged.

• Next-Generation Battery Technology Comes to the Fore

On January 3, 2024, PowerCo, a battery subsidiary of Volkswagen, announced that its partner, QuantumScape, had successfully passed its first endurance test on solid-state batteries, achieving over 1,000 charge-discharge cycles while maintaining a capacity of over 95%.

Additionally, in September 2023, another solid-state battery listed company based in the US, Solid Power, announced that its first batch of A-1 solid-state battery samples had been officially delivered to BMW for automotive verification testing. BMW aims to launch its first prototype vehicle based on Solid Power’s solid-state battery technology by 2025.

Last year, Toyota has repeatedly stated its intention to commercialize solid-state battery technology by 2027-2028.

• Does All-Solid-State Battery (ASSB) Technology Truly has the Potential to Overturn Liquid-State Battery Technology?

Traditional liquid-state LiB is primarily composed of cathode and anode electrodes, separator, and electrolyte. The cathode and anode electrode materials play the role of storing lithium, which affects the battery’s energy density, while the electrolyte mainly influences the motion rate of lithium ion during charging and discharging processes, typically using liquid (Organic solvents) as the electrolyte.

However, during the charge-discharge process of traditional liquid-state LiB, side reactions can easily occur on the electrode surface. For example, lithium dendrites formed on the surface of the anode electrode can easily penetrate the separator, causing a short circuit between the cathode and anode electrodes and leading to battery fires.

In addition, the liquid electrolyte is a flammable substance, making liquid-state batteries prone to ignition and explosion under high temperatures or when the battery experiences external impacts that result in a short circuit. Therefore, liquid-state battery faces significant challenges in terms of safety.

Compared to liquid-state LiB, the electrolyte in ASSB is solid, which is less volatile or prone to combustion. Meanwhile, solid-state electrolytes are temperature-stable and less prone to decomposition, rendering them highly safe.

Furthermore, solid-state electrolytes exhibit better stability and mechanical properties, providing superior suppression of lithium dendrites and thereby enhancing battery safety.

On the other hand, traditional liquid-state LiB is limited in their choice of materials due to their narrow electrochemical window and side reactions between the liquid electrolyte and the cathode and anode electrode materials. Solid-state electrolytes, however, offer a wider electrochemical window and fewer side reactions, allowing for a broader range of electrode materials to be used in solid-state battery.

This enables the use of higher energy density active materials. For instance, solid-state battery based on lithium metal anodes can achieve energy densities of over 500 Wh/kg, while liquid-state LiBs can hardly reach this level, with a theoretical energy density limit of 350 Wh/kg. Currently, traditional liquid-state LiBs have approached their theoretical energy density limit, and there’s little room for further improvement.

On top of that, ASSB also boasts better temperature adaptability (-30 to 100°C) and high power characteristic, which can help improve the operating temperature range and fast-charging performance of EV battery.

Meanwhile, as there is no need for liquid electrolytes and separators, the weight of ASSB cells can be reduced. Additionally, processes such as electrolyte filling, degassing, molding, and aging can be removed during the cell assembly process, simplifying the cell manufacturing process. As a whole, given its outstanding performance, ASSB indeed holds the potential to revolutionize liquid-state LiB.

Currently, ASSB, in face of a series of technical challenges, has not yet achieved large-scale production. These challenges include the batch preparation of electrolyte materials, interface stability/side effects between solid materials, as well as the breakthrough of technical hurdles in cell preparation processes, production equipment, and other aspects.

Still, with significant attention and investment from countries worldwide, including Japan, South Korea, Europe, and the US, ASSB has made important progresses and is expected to achieve mass production within 3-5 years.

• Will China be Overtaken in the Market Competition of All-Solid-State Battery?

Currently, ASSB has emerged as the high ground in the competition for next-generation battery technology. The development of ASSB has been listed as a national development strategy by major countries and regions such as Japan, South Korea, the US, and the European Union, and global enterprises are actively making inroads in this field.

Based on different solid electrolyte technical routes, ASSB can be divided into four types: polymer, oxide, halide, and sulfide solid-state batteries. Each of these technology routes has its own advantages and disadvantages. Currently, Japan and South Korea mainly select sulfide as the primary technical route.

In light of the development progress of ASSB in major regions globally, Japan is an early starter in R&D, which takes a lead in the application of patents, and accumulates the most solid-state battery patented technologies worldwide. Japanese companies like Toyota and Nissan have stated their intention to achieve mass production of ASSB around 2028.

In South Korea, major battery manufacturers like Samsung SDI, SK Innovation, and LG Energy Solutions continue to invest in R&D. Samsung SDI completed the construction of a pilot production line (S-line) for ASSBs in 2023 and plans to achieve mass production in 2027.

In the United States, solid-state battery development is primarily led by startups with high innovation potential. Companies like QuantumScape and Solid Power have solid-state battery products in the A-sample stage, while SES’ lithium-metal solid-state batteries have entered the B-sample stage. Other US companies such as Ampcera, Factorial Energy, 24M Technologies, and Ionic Materials have channeled more efforts in solid-state battery technical innovation.

Overall, the period around 2028 is expected to be tipping point for the mass production of ASSB.

Although China is currently the world’s largest manufacturer of LiB, there is still a significant gap between Chinese companies and international ones in terms of patent layout for ASSB.

Additionally, China’s solid-state battery technical routes are diverse, with a focus mainly on semi-solid/state-liquid hybrids, with semi-solid-state battery achieving small-scale production and adoption in vehicles, but investment in ASSB remains insufficient in China, and resources are dispersed. This has led to a significant difference compared to international forerunners.

Therefore, in the future competition for ASSB, companies from Japan, South Korea, Europe, and the US have the opportunity to surpass China and reshape the competitive landscape of future EV battery industry.

Japan and the EU are reportedly set to launch formal cooperation in the research and development of advanced materials, such as chips and electric vehicle batteries. According to a report from NIKKEI, this initiative aims to decrease their high reliance on suppliers from China. Iliana Ivanova, Commissioner for Innovation and Research at the EU, revealed that the two parties will establish a collaborative framework in April.

As per the same report, Commissioner Ivanova stated during an interview that both Japan and the EU remain globally leading in advanced materials innovation. In 2020, the EU’s investment in this industry totaled EUR 19.8 billion, while Japan’s amounted to EUR 14 billion.

Under the framework tentatively named “Dialogue on Advanced Materials,” Japan and the EU plan to hold regular meetings to discuss collaboration proposals. Institutions engaged in advanced materials research from both sides will also participate. Commissioner Ivanova highlighted that the areas of cooperation include renewable energy, transportation, construction, and electronic materials. She also expressed hope for Japan and the EU to jointly develop international standards for advanced materials.

The report highlights a specific area of focus: the development of sodium-ion batteries, which are seen as the most promising next-generation power source for electric vehicles.

In recent years, the rapid growth of the global electric vehicle and energy storage markets has driven robust demand for lithium-ion batteries. As per TrendForce’s data, with further expansion expected in these sectors, the demand for lithium batteries is projected to continue growing, surpassing 3200GWh in global shipments by 2027.

Currently, China dominates the global lithium battery supply chain system, including battery metal refining, battery material processing, and battery manufacturing. Per TrendForce, more than 75% of lithium batteries worldwide are currently produced in China, making it the global leader in lithium battery manufacturing capacity.

In regard to China’s competitive advantage in the LiBs field today, it’s difficult for Japanese and South Korean companies to surpass. And it’s even more challenging for the US and Europe to catch up with China, due to the weak foundation of LiB industry locally. However, the emergence of inexhaustible and inexpensive sodium batteries may have offered a solution for the world to reduce its reliance on China.

Sodium-ion batteries do not require the use of rare metals controlled by China and have lower production costs compared to traditional batteries. The EU hopes to make progress in this area to meet the increasing demand brought about by the transition to electric vehicles.

Additionally, the EU aims to leverage Japan’s leading knowledge in metal nanoparticle technology, which can enhance solar energy conversion efficiency. Nanoparticle materials can also help smartphones save energy. In the future, the EU plans to allocate significant funding to advanced materials research, fully supporting related research and large-scale production.
