lithium-ion battery is Convert stored chemical energy into electrical energy. …. Li-ion batteries, lithium ions move from the anode to cathode during discharge, and from cathode to anode when charging……
The materials used for the anode and cathode can dramatically affect a number of aspects of the battery’s performance, ...... Such as ในรูป The volumetric capacity of silicon (Wh/cc), i.e. the capacity of silicon taking into account volume increases resulting from lithium insertion, is still significantly higher than that associated with carbon anode materials. …. SEI formation on silicon
anodes during the first cycle causes a high irreversible capacity
loss and can result in low Coulombic efficiency (CE) values
such as 25−75%, depending on the structure of the silicon and
the composition of the anode composite.
