Formation of a glue-nanofiller layer between grains, consisting of a middle-temperature spinel-like Lix CoO2 phase, reinforces the strength of the incoherent interfacial binding between anisotropically oriented grains by enhancing the face-to-face adhesion strength. The cathode treated with the glue-layer exhibits steady cycling performance at both room-temperature and 60 °C. These results represent a step forward in advanced lithium-ion batteries via simple cathode coating.
在晶粒之间形成了一层胶态纳米填料层,由中温尖晶石状 LixCoO2 相组成,通过提高面对面的黏附强度来增强各向异性取向晶粒之间的非晶态界面结合强度。经胶层处理的阴极在室温及 60°C 下均表现出稳定的循环性能。这些结果通过简单的阴极涂覆,代表了先进锂离子电池的一个进步。
