All-solid-state lithium batteries (ASSLIBs) employing sulfide solid electrolyte hold high promise to replace traditional liquid-electrolyte LIBs due to their high safety and energy density. However, Li dendritic growth in sulfide electrolyte limits the realization of the high energy of ASSLIBs. In this work, we use LiF (or LiI) layer at the interface between Li and sulfide electrolyte and penetrated HFE (or I solution) inside of sulfide electrolyte to suppress the Li dendrite growth. Due to the higher interface energy of LiF/Li than that of LiI/Li, LiF interlayer show much higher capability than LiI in suppressing the Li dendrite. Even if the Li dendrite breaks through LiF (or LiI) interlayer, the Li dendrites will be consumed by coated/penetrated HEF (or I) forming LiF (or LiI) thus preventing Li dendrite growth. A LiNbO₃ @LiCoO₂/Li₇P₃S₁₁/Li ASSLIB employing HFE coated/infiltrated Li₇P₃S₁₁ glass-ceramic as electrolyte, and LiF coated Li metal as anode shows a high reversible discharge capacity of 118.9 mAh g⁻¹ at 0.1 mA cm⁻² and retains 96.8 mAh g⁻¹ after 100 cycles. The designed solid electrolyte interphase between Li and solid electrolyte that has a high interface energy to Li provides new opportunity to commercialize the Li metal batteries.

采用硫化物固体电解质的全固态锂电池（ASSLIB）具​​有很高的安全性和能量密度，有望取代传统的液体电解质LIB。但是，硫化物电解质中锂的树枝状生长限制了ASSLIBs高能量的实现。在这项工作中，我们在Li和硫化物电解质之间的界面处使用LiF（或LiI）层，并渗透到硫化物电解质内部的HFE（或I溶液）中，以抑制Li树枝状晶体的生长。由于LiF / Li的界面能比LiI / Li的界面能高，因此LiF中间层显示出比LiI高得多的抑制Li枝晶的能力。即使Li树枝状晶体突破了LiF（或LiI）中间层，Li树枝状晶体也会被涂覆/穿透的HEF（或I）形成LiF（或LiI）所消耗，从而阻止Li树枝状晶体的生长。铌酸锂₃@LiCoO ₂ /锂₇ P ₃小号₁₁ /锂ASSLIB采用HFE涂覆/渗透栗₇ P ₃小号_11个玻璃-陶瓷作为电解质和LiF包覆Li金属作为阳极节目118.9毫安g的高可逆放电容量^-1在0.1 mA cm ^-2并在100个循环后保留96.8 mAh g ^-1。锂与具有高界面能的锂之间的固体电解质中间相的设计为将金属锂电池商业化提供了新的机会。
