Herein,we report a novel strategy to utilize polymeric cobalt phthalocyanine withtriethylene glycol linker (TEGCoPPc) as an effective channeling additive for Sianode, which can simultaneously alleviate the capacity fading of Si microparticles. Owing to the excellent coating ability,TEGCoPPc can be uniformly coated on carbon nanotubes (TEGCoPPc@CNT), which canfurther enhance the performance of resulting silicon anodes. The Si anodewith TEGCoPPc@CNT additives exhibits high rate capability and stable cyclingperformance (1539 mA h g-1 at the current density of 8.4 A g-1,and 1040 mAh g-1 after200 Cycles at the current density of 2.1 A g-1). This study welldemonstrates the potential of phthalocyanine-based organic materials to supplement drawbacks of Si anode forLIBs. |
