Decomposition reaction of LiPF6-based electrolytes for lithium ion cells
Water is undesirable for lithium ion batteries and lithium batteries because it causes a decomposition of their components. It has been reported that water decomposes lithium alkyl carbonates, which are components of the solid electrolyte interphase (SEI) in a carbon anode for lithium ion batteries [6].
