Pre-engineering artificial solid electrolyte interphase for hard carbon anodes for superior sodium storage
1Institute of Intelligent Flexible Mechatronics & School of Mechanical Engineering, Jiangsu University, Zhenjiang, 212013, China.
Abstract:
A 5-nm-thick artificial solid electrolyte interface (SEI) was engineered for the hard carbon anodes of sodium-ion batteries. Benefiting from the artificial SEI, the hard carbon anode shows a significantly improved initial Coulombic efficiency of 94% and superior rate performance with a reversible capacity of 247 mA h g-1 after 800 cycles at 1C, 220 mA h g-1 after 400 cycles at 6C.
