Summary:Disclosed are a method for manufacturing an electrode of a lithium ion battery for rapid charging and an electrode of a lithium ion battery. According to one specific embodiment, a TiO_2(B) nano-belt is manufactured from titanium dioxide powder to form a channel for lithium ion transport and an active site in more open shape, the intrinsic properties of titanium dioxide are improved by doping with nitrogen to adjust an electronic structure of titanium dioxide, and an internal surface area and electrical conductivity can be increased, thereby improving the stable fast charging performance of a lithium ion secondary battery. 본 기술은 급속 충전용 리튬이온전지의 전극 제조방법 및 리튬이온전지의 전극이 개시되어 있으며, 본 구체적인 실시 예에 의하면 이산화 티타늄 파우더로부터 TiO2(B)나노 벨트를 제작하여 리튬이온 수송을 위한 채널 및 활성 사이트를 보다 개방된 형태를 형성하고, 질소를 도핑하여이산화 티타늄의 전자 구조를 조정함으로써 이산화 티타늄의 고유 특성을 개선하고, 내부 표면적 및 전기 전도성을 증가시킬 수 있고, 이에 리튬이온 이차전지의 안정적인 고속 충전 성능을 향상시킬 수 있다.
