英文摘要 | Solid-state batteries (SSBs) can essentially improve battery safety. Garnet-type Li7La3Zr2O12(LLZO) is considered one of the most promising solid electrolytes for SSBs. However, the performance of LLZO-based SSBs is limited by the large cathode/electrolyte interfacial resistance. High-rate and long-cycling SSBs were achieved only after adding flammable polymer or liquid electrolyte in the cathode at the sacrifice of safety. Here, we show that an all-ceramic cathode/electrolyte with an extremely low interfacial resistance can be realized by thermally soldering LiCoO2(LCO) and LLZO together with the Li2.3−xC0.7+xB0.3−xO3solid electrolyte interphase through the reaction between the Li2.3C0.7B0.3O3solder and the Li2CO3layers that can be conformally coated on both LLZO and LCO. The all-solid-state Li/LLZO/LCO battery with such an all-ceramic cathode/electrolyte exhibits high cycling stability and high rate performance, constituting a significant step toward the practical applications of SSBs. All-solid-state lithium batteries can essentially improve battery safety. However, the performance of all-solid-state batteries is limited by the large interfacial resistance between electrode and electrolyte. As a compromise, flammable liquid or polymer electrolyte was usually added at the electrode/electrolyte interface at a sacrifice of safety. Here we report a unique strategy of lowering the interfacial resistance between LiCoO2cathode and Li7La3Zr2O12electrolyte, so that all-ceramic cathode composite of intrinsically high safety can be achieved. Such an all-ceramic cathode-electrolyte enabled all-solid-state Li/LLZO/LiCoO2batteries with high cycling stability. In addition, this approach is not limited to LiCoO2cathode but can also be applied to other layered transition-metal oxide cathodes, promoting the practical application of all-solid-state lithium batteries. All-ceramic cathode-electrolyte with a low interfacial resistance can be realized by thermally soldering LiCoO2and Li7La3Zr2O12(LLZO) together with Li2.3−xC0.7+xB0.3−xO3solid electrolyte interphase through the reaction between the Li2.3C0.7B0.3O3solder and the Li2CO3layers that can be spontaneously coated on both LLZO and LiCoO2. The all-solid-state Li/LLZO/LiCoO2battery with such an all-ceramic cathode/electrolyte exhibits high cycling stability and high rate performance. © 2018 Elsevier Inc. |
