Spider silk binder for Si-based anode in lithium-ion batteries

DongWoong Choi, Kwang-Leong Choy
2020 Materials & design  
This is a novel approach of using natural spider silk as the effective binder material. • The spider silk based electrodes with various weight ratios exhibited superior cyclic stability at 250 mA•g −1 . • The enhanced cycling property was demonstrated through cyclic voltammetry, impedance, and performance tests. • Such superior performance of the cell with spider silk binder might be attributed by the unique properties of silk.
