Technology of improving lithium ion storage performance of silicon negative electrode by all carbon graphite alkyne grown at low temperature

Si negative electrode material is one of the lithium ion negative electrode materials with high theoretical lithium storage energy in lithium ion batteries. Its theoretical capacity can reach more than 4000 MAH g-1. However, when Si negative electrode material stores lithium, it is prone to volume expansion, resulting in electrode pulverization and sharp decline in […]
