The Need

The advancement of lithium-ion battery technology relies heavily on increasing energy density, yet practical usage of silicon (Si) anodes faces challenges due to parasitic side reactions and active lithium consumption. Controlling lithium amounts precisely while achieving uniform distribution remains a significant challenge in pre-lithiation techniques. There's a critical need for innovative approaches to pre-lithiation that address these issues and optimize battery performance.

The Technology

Our synthetic approaches aim to compensate for lithium loss in batteries, particularly in silicon anodes. By addressing issues such as electrolyte decomposition and solid electrolyte interphase (SEI) formation, our method reduces lithium loss and ensures a uniform reaction with the oxide present. This approach involves thermal evaporation of lithium metal, enabling precise control of pre-lithiation degree and homogeneous lithium deposition on the anode surface.
