Title:
リチウム二次電池用コア-シェル型負極活物質、その製造方法、、これを含むリチウム二次電池用の負極及びリチウム二次電池
Document Type and Number:
Japanese Patent JP2011515012
Kind Code:
A
Abstract:
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.
