Summary: GS Yuasa Corporation, a Japanese battery manufacturer, plans to commercialize lithium-ion batteries that don’t use graphite by 2030, starting with applications in ships. The company will replace graphite with silicon as the negative electrode material. This move is driven by concerns over reliance on China for graphite supply. While Toshiba is developing lithium-ion batteries without graphite in the negative electrode material, GS Yuasa’s attempt to completely replace graphite with silicon is rare.
GS Yuasa aims to first commercialize the technology for ships and aircraft. After achieving this, the company will consider applications in electric vehicles and hybrid vehicles if the batteries can withstand repeated charging and discharging without significant degradation.
GS Yuasa currently has a small share of the automotive lithium-ion battery market. The company plans to expand its capacity and develop new products to enhance its market presence. This is part of a joint venture with Honda to invest 434.1 billion yen in electric vehicle battery development and a new factory in Japan.
Graphite is commonly used as the negative electrode material in lithium-ion batteries due to its stability and safety. However, it has limitations in terms of capacity and dependence on China for supply.
Silicon is seen as a promising alternative to graphite, but it has the drawback of accelerated battery degradation. GS Yuasa is tackling this issue by improving the adhesive materials for connecting components and the electrolyte for electrical exchange.
