5. Silicon Anode Lithium-Ion Batteries

In this technology, the anode is made up of silicon and lithium-ions are charge carriers. Silicon is one of the promising anode materials for lithium-ion batteries. It has a record capacity of about 4000 mAh/g, which is ten times higher than graphite. These anodes add a binder for increased mechanical stability and carbon as a conductive additive.

Silicon enhances the energy density of lithium-ion batteries when used as the anode. Each silicon atom can bind up to 3.75 lithium atoms in its fully lithiated state compared to one lithium atom per 6 carbon atoms for fully lithiated graphite. Hence, silicon composes great gravimetric and volumetric capacities. The performance of silicon is higher than graphite in electric vehicle batteries. It is also cheaper than other materials and has fewer environmental impacts. 

Enovix is a developer and manufacturer of 100% silicon anodes. The company has also developed 3D cell architecture for higher energy density.  Silicon anode battery is used in some electric vehicles, but most EVs don’t use it. The main reason for not using silicon anode is impractical driving ranges. It also increases the mass of the vehicle which leads to the increased manufacturing cost of vehicles.
