Graphite Anode for a Potassium-Ion Battery With Unprecedented Performance
Angewandte Chemie - International Edition, 2019AbstractGraphite as an anode for the potassium ion battery (PIBs) has the merits of low cost and potentially high energy density, while suffering from limited cycle time and inferior stability. Herein we, using a concentrated electrolyte, demonstrate that formation of a robust inorganic‐rich passivation layer on the graphite anode could resolve these ...
