"protein-modified SEIs Li anodes different stand-still temperatures... heat treatment protein denaturation... unfolded chain structures... heat-treated-zein-modified (H-zein-modified) SEI better wetting behavior and faster SEI formation than unheated sample (U-zein)... symmetrical LiFePO4/Li cell H-zein-modified SEI stable long-term cycling performance higher capacity retention (70%)... after 200 cycles... H-zein-modified SEI stable long-term cycling... symmetrical Li|Li and full cells"
