Title
(EN) NEGATIVE ELECTRODE ACTIVE MATERIAL FOR CHARGING DEVICE
(KO) 축전 디바이스용 음극 활물질
Abstract
(EN) A carbon material that provides a charging device not only ensuring a high energy density but also realizing a high output and an excellent low-temperature performance. There is provided a negative electrode active material for charging device having an aprotic organic solvent electrolyte solution containing a lithium salt as an electrolyte, characterized by consisting of a carbon material of 0.01 to 50 m 2/g specific surface area and 0.005 to 1.0 cc/g total mesopore volume wherein mesopore volumes of 100 to 400Åpore diameter occupy 25% or more of the total mesopore volume. ©KIPO&WIPO 2008
(KO) 고에너지 밀도 외에, 고출력으로 저온특성에 뛰어난 축전 디바이스를 야기하는 탄소재료를 제공한다. 전해질로서 리튬 염을 포함하는 비양성자성 유기용매 전해질 용액을 구비하는 축전 디바이스용 음극 활물질로서, 비교면적이 0.01∼50m/g이고, 전체 메소 구멍용적이 0.005∼1.0cc/g이고, 세공 직경 100∼400Å의 메소 구멍용적이 전체 메소 구멍용적의 25%이상을 차지하는 탄소재료로 이루어지는 것을 특징으로 하는 축전 디바이스용 음극 활물질이다. 2
