Title:
GERMANIUM NANOPARTICLE/CARBON COMPOSITE ANODE MATERIAL USING NO BINDER FOR LITHIUM-POLYMER BATTERY HAVING HIGH CAPACITY AND HIGH RAPID CHARGE/DISCHARGE CHARACTERISTICS
Document Type and Number:
WIPO Patent Application WO/2013/125761
Kind Code:
A1
Abstract:
The present invention relates to an anode active material for a lithium-polymer battery having high capacity and high rapid charge/discharge characteristics, and a lithium-polymer battery using the same, and more specifically, to: a non-carbonaceous nanoparticle/carbon composite anode material using no binder; a lithium-polymer battery having high capacity and high rapid charge/discharge characteristics using the same; and a preparation method thereof. According to the present invention, the lithium-polymer secondary battery comprises an anode active material prepared by carbonizing a composite in which polymer particles comprising non-carbonaceous nanoparticles are dispersed in a polymer resin. According to the present invention, the anode active material allows non-carbonaceous nanoparticles to be dispersed in and fixed to a carbonized body even without a binder.
