Solidion Technology Says It Plans To Begin Expanding Production Capacity Of Silicon-rich Graphene Composite Materials In Early 2025
The amount of energy that a lithium-ion battery can supply to an electric vehicle (EV) is limited by the amount of charges stored in its anode and cathode materials. Although graphite has been the preferred anode material during the past 30 years, silicon oxide (SiOx) and silicon (Si) are two evolving anode materials capable of improving the energy density of EV batteries and extending the EV range by 20-40%. However, the higher-capacity gain of both silicon and silicon oxide is limited by the technical issue of large volume change-induced rapid capacity decay and processing difficulty.
鋰離子電池向電動汽車提供的能源量受其負極和正極材料中儲存的電荷量限制。雖然石墨是過去30年間首選的負極材料，但二氧化硅（SiOx）和硅（Si）是兩種正在發展的負極材料，能夠提高電動汽車電池的能量密度，並將電動汽車的續航里程延長20-40%。但是，無論是硅還是二氧化硅的更高容量增益，都受到大體積變化誘導的快速容量衰減和加工難度技術問題的限制。
