Silicon (Si) is one of the most promising candidates for application as high-capacity negative electrode (anode) material in lithium ion batteries (LIBs) due to its high specific capacity. However, evoked by huge volume changes upon (de)lithiation, several issues lead to a rather poor electrochemical perform-ance of Si-based LIB cells.
However, when silicon is used as a negative electrode material, silicon particles undergo significant volume expansion and contraction (approximately 300%) in the processes of lithiation and delithiation, respectively.
Pure silicon negative electrodes have huge volume expansion effects and SEI membranes (solid electrolyte interface) are easily damaged. Therefore, researchers have improved the performance of negative electrode materials through silicon-carbon composites.

An explosion-proof valve is a critical safety feature in a lithium-ion battery designed to safeguard it against thermal runaway. Usually located on its casing, this valve monitors internal pressure changes before opening to release any built-up pressure within and prevent damage.
The Li-Ion battery may be subjected to high risk of explosion if for example it is selected a wrong chemical type for the cell or an improper mechanical construction design and distancing between the cells, thus making the thermal runaway effect more likely to happen.
Prismatic lithium-ion batteries in portable electronics typically incorporate an explosion-proof valve at the top of their battery case, designed to open easily in response to increasing internal pressure. When an internal short circuit or overcharging occurs, this reaction could produce heat and gas, generating an explosion if leave unmanaged.
