Schematic representations of lithiation/delithiation of silicon particles using conventional binder a and the SHPET binder b Although silicon-based materials have a large specific capacity, they have not yet been widely used in lithium-ion batteries. The main reason is that the large volume change of silicon leads to poor cycle performance.

tly, the specific impact of silicon wafer resistivity remains unclear. This paper delves deeper into this subject and reveals that a low resistivity yields a high implied open-circuit voltage (iVoc), yet it also leads to an increase in saturation
The different lithium storage properties of Si and graphite lead to different degrees of lithiation and chemical environments for this composite anode, which significantly affects the performance of batteries.
Silicon-based all-solid-state batteries (Si-based ASSBs) are recognized as the most promising alternatives to lithium-based (Li-based) ASSBs due to their low-cost, high-energy density, and reliable safety.
The unit cell volume of Si-Li alloy is larger than that of crystalline silicon. It can be concluded from Table 1 that when Si is alloyed with Li to form Li 4.4 Si, the volume changes by about 400%. This expansion will change the internal structure of the silicon material and cause the material to break.
