Han Media: China Leads in Solving the Solid-State Battery Problem, South Korean Battery Industry Faces Crisis!
On November 13, the South Korean media outlet "Newdaily" published an article stating that China has taken a significant step toward leading in the field of solid-state batteries. Solid-state batteries are expected to be applied in various fields from humanoid robots to electric vehicles, and are seen as future growth engines. Although the South Korean battery industry is accelerating its development, the sense of crisis of possibly falling behind China is increasing.
Chinese Academy of Sciences researchers have recently solved the "interface gap formation problem," which is a key challenge in commercializing solid-state lithium batteries.
The research team at the Chinese Academy of Sciences developed a "self-adaptive interface phase" structure, which automatically makes the positive electrode and electrolyte adhere to each other. Through this structure, they successfully achieved an energy density of over 500 watt-hours per kilogram, while simplifying the manufacturing process, improving stability, and not increasing production costs.
The research team reported: "The prototype battery using the new technology maintained high stability and performance even after hundreds of charge-discharge tests." Chinese local media evaluated that this technological advancement will not only enhance China's competitive advantage in the electric vehicle field but also strengthen China's competitive advantage in next-generation industries such as flexible electronic devices and humanoid robots.
In fact, in order to achieve innovation in humanoid robots and next-generation wearable devices, solid-state batteries have attracted much attention. Traditional liquid electrolyte batteries pose risks of expansion or fire due to environmental changes, while solid-state batteries use solid electrolytes, which are safer. They almost do not require additional safety devices, reduce volume, and improve energy density and performance.
The South Korean battery industry is also accelerating the commercialization of solid-state batteries. If China also takes the lead in the solid-state battery field, South Korean companies will face a crisis with no way out.
Currently, the global battery market is dominated by Chinese battery companies such as Contemporary Amperex Technology Co., Limited (CATL) and BYD, mainly with low- to medium-priced lithium iron phosphate (LFP) batteries. South Korean battery companies, which have focused on high-end ternary batteries, started developing LFP batteries later, but the dominance has already shifted to China.
