A selective catalysis anionic decomposition strategy for Li metal anode is reported by charge-separated TP-COF. The strong adsorption between TP-COF and FSI⁻ lowers the lowest unoccupied molecular orbital (LUMO) energy level of FSI⁻, accelerating the decomposition of FSI⁻ and generating a stable LiF-rich SEI. Consequently, dendrite-free lithium deposition and high-energy-density lithium metal batteries were achieved under realistic conditions.

通过电荷分离 COF 中间层增强稳定锂金属软包电池的阴离子选择性催化

电荷分离的 TP-COF 报道了锂金属阳极的选择性催化阴离子分解策略。 TP-COF和FSI ^-之间的强吸附降低了FSI ^-的最低未占分子轨道（LUMO）能级，加速了FSI ^-的分解并生成稳定的富含LiF的SEI。因此，在现实条件下实现了无枝晶锂沉积和高能量密度锂金属电池。
