Interfaces and Electrolyte Additives for Long-Life Sodium-Ion and Lithium-Ion Batteries

摘要

Sodium-ion batteries (NIBs) are attracting considerable attention as post lithium-ion batteries (LIBs) as they are a likely 'drop-in' technology which can be produced using existing manufacturing lines. One of the processes in manufacturing which is least understood is the formation and conditioning step; both battery technologies require a formation of the surface electrolyte interface (SEI) and cathode electrolyte interface (CEI) for long life cells. Here we discuss the formation, conditioning and electrolyte additives for the creation of the stable interfaces for high cycle life.
