"overcomes electrode/ electrolyte interface side reactions causing short cycle life, by using glutamate additives building EEI layers... cathode undergoes radical-initiated electro-polymerization resulting in EEI layer dominated by electropolymerized polyglutamic acid... anode polymerizes via polycondensation reaction, forming robust EEI layer dominated by polycondensation-induced PGA... suppress active material loss, by-product accumulation, Zn dendrite growth... facilitates ionic diffusion/ desolvation"
