CORE-SHELL TYPE ANODE ACTIVE MATERIAL FOR LITHIUM SECONDARY BATTERIES, METHOD FOR PREPARING THE SAME AND LITHIUM SECONDARY BATTERIES COMPRISING THE SAME |
摘要 |
Provided are a core-shell type anode active material for lithium secondary batteries including a carbonaceous material core; and a shell formed outside the carbonaceous material core, the shell including a PTC (Positive Temperature Coefficient) medium. The core-shell type anode active material for lithium secondary batteries has the shell including the PTC medium, and thus has the improved conductivity and high output density, exhibiting excellent electrical characteristics. And, a lithium secondary battery manufactured using the anode active material has excellent safety, in particular safety against overcharge and external short circuit. |
