采用原位法在Li阳极表面制备Li 3 N保护层,在阳极保护的基础上抑制穿梭效应。在不含LiNO 3的电解质中,500次循环后放电容量保持在773 mA h g(-1),平均库仑效率为92.3%,而简单硫阴极的硫负载量为2.5-3 mg cm(-2)。
A Li3N protection layer is fabricated on the surface of a Li anode by an in situ method to suppress the shuttle effect on the basis of anode protection. The discharge capacity is retained at 773 mA h g(-1) after 500 cycles with an average coulombic efficiency of 92.3% in the electrolyte without LiNO3, while the sulfur loading of the simple sulfur cathode was 2.5-3 mg cm(-2).
