摘要

硫化物基全固态锂金属电池（asslmb）因其高能量密度和安全性而成为下一代电池。然而，锂阳极面临着枝晶生长和锂金属-硫化物电解质界面副反应等挑战。在本研究中，我们通过将金属锂与含有硝基甲烷、二甲氧基乙烯和硝酸锂的溶液反应，消除金属锂表面的电阻性天然层，形成具有高离子导电性、机械强度和内聚性的保护层。具有表面修饰的锂对称电池具有2.8 mA cm-2的高临界电流密度，并且在30℃下稳定循环1000 h以上。采用表面改性锂阳极、Li6PS5Cl电解液和lini0.78 co0.10 mn0.120 o2阴极的ASSLMB在0.3℃和30℃条件下具有183.2 mAh g-1的高放电容量和300次不短路的稳定循环，解决了ASSLMB开发中锂金属的关键挑战问题。

Surface-Modified Lithium Enabling High-Performance All-Solid-State Lithium Metal Batteries

Sulfide-based all-solid-state lithium metal batteries (ASSLMBs) are promising next-generation batteries due to their high energy density and safety. However, lithium anodes face challenges like dendrite growth and side reactions at the lithium metal-sulfide electrolyte interface. In this study, we eliminated the resistive native layer on lithium metal and formed a protective layer with high ionic conductivity, mechanical strength, and cohesion by reacting lithium metal with a solution containing nitromethane, dimethoxyethene, and lithium nitrate. The lithium symmetric cell with the surface-modified Li exhibited a high critical current density of 2.8 mA cm^–2 and stable cycling over 1000 h at 30 °C. The ASSLMB with surface-modified Li anode, Li₆PS₅Cl electrolyte, and LiNi_0.78Co_0.10Mn_0.12O₂ cathode achieved a high discharge capacity (183.2 mAh g^–1) and stable cycling for 300 cycles without short-circuit at 0.3 C and 30 °C, which enabled solving the critical challenging issues of Li metal for the development of ASSLMBs.
