the coating layers are capable
of improving the ionic or electronic conductivity, suppressing
phase transition, increasing structural stability, decreasing the
disorder of cations in crystal sites, reducing transition metal
dissolution, acting as a HF scavenger to reduce the electrolyte
acidity, favoring the formation of solid–electrolyte-interface
(SEI) film on the anode surface, and so on, electrode resistance,
side reactions and heat generation during cycling are decreased,
which consequently leads to a remarkable improvement in cycle
life, rate capability, reversible capacity, coulomb efficiency of
the first cycle, and overcharge tolerance |
