High Performance Li-ion battery Anodes based on Si Nano core in an LATP Matrix with better Electrolyte Compatibility and Temperature Resistance

摘要

Novel core/matrix morphologies of Silicon nanostructures/ LATP ceramics are synthesized through a sol - gel assisted method. The Li1.3 Al0.3 Ti1.7(PO4)3 powders were coated on Si nanoparticles as an artificial SEI layer selectively conducting Li cations, which also prevents the formation of the thick natural SEI layer formation, improving the cyclic stability.
