Winning the Battery Race: How the United States Can Leapfrog China to Dominate Next-Generation Battery Technologies
The United States battery industry has fallen dangerously behind the global leaders. A cornerstone of the modern economy, batteries are essential and ubiquitous across consumer electronics such as cellphones, military equipment such as drones, and clean energy products such as electric vehicles (EVs) and power grid storage installations. Over the past decade, China has come to dominate this critical industry. Across every stage of the value chain for current-generation lithium-ion battery technologies, from mineral extraction and processing to battery manufacturing, China’s share of the global market is 70–90 percent. Japan and South Korea, once world leaders in battery technology and production, now hold minority market shares, and the United States is in a distant fourth place. As a result, the United States almost entirely relies on Asian imports for the batteries widely used today.
The good news is that after years of development, far superior battery technologies could reach commercial markets in the coming decade—and the race to scale them up remains wide open. Next-generation batteries represent a fundamentally new architecture compared with today’s lithium-ion batteries, leaving behind liquid components for a solid-state architecture and eliminating graphite, a material over which China has a chokehold on production. U.S. companies and research institutions have made strides toward commercializing next-generation batteries with dramatically better performance. These batteries have expanded energy storage, quicker charging rates, and radical safety improvements. Yet competition is intense, with U.S. rivals in Asia investing heavily in innovation. Washington will have to act with force and speed to recover from its disastrous start in the global battery competition and leapfrog China’s lead.

SAIC plans to start mass production of its second-generation solid-state battery by 2026, boasting an energy density of 400 Wh/kg. Meanwhile, CATL aims for a 500 Wh/kg solid-state battery by 2027, showcasing the competitive nature of the industry.
Chery has claimed to be the first company to establish a 1 GWh solid-state battery production line, which could revolutionize the market. This production line is expected to produce batteries with energy densities exceeding 400 Wh/kg by 2025 and 500 Wh/kg by 2027. These advancements highlight the rapid progress being made in the solid-state battery sector.
Advantages of Solid-State Batteries
Solid-state batteries offer several advantages over traditional lithium-ion batteries. Their higher energy density allows for longer-lasting power in smaller packages, making them ideal for electric vehicles and portable electronics. Additionally, their inherent safety features reduce the risk of fires and explosions, a significant concern with lithium-ion technology.
The longer cycle life of solid-state batteries means they can be charged and discharged more times before degrading, making them more cost-effective in the long run. Furthermore, their ability to operate in extreme temperatures expands their potential applications across various industries.
Challenges Ahead
Despite the promising future of solid-state batteries, several challenges remain. The manufacturing processes for solid-state batteries are still being refined, and scaling production to meet demand will require significant investment. Additionally, the cost of materials and production methods must be reduced to make solid-state batteries commercially viable.
Competition from established lithium-ion battery manufacturers poses another challenge. Companies like Tesla and Panasonic have significant market share and experience in lithium-ion technology, making it difficult for new entrants to gain a foothold.
Conclusion
The race to dominate the next generation of battery technology is critical for the United States. With significant investments in research and development, the U.S. has the potential to leapfrog China and establish itself as a leader in solid-state battery technology. By focusing on innovation and scaling production, the U.S. can secure its position in the global battery market.
As companies like SAIC, CATL, and Chery continue to push the boundaries of solid-state battery technology, the future of energy storage looks promising.
