Abstract
The exfoliation of graphite (layer) was progressed due to the irreversible insertion of PC molecules between graphene layers, when propylene carbonate (PC) solvent was used as the organic solvents. The problem could be mitigated by the replacement of PC by ethylene carbonate (EC). But, the freezing point of EC-based electrolyte increased due to the high freezing point of
흑연재료를 부극으로 사용하는 리튬2차전지의 유기 전해액으로 propylene carbonate(PC) 용매를 사용하면 흑연층간에 PC의 비가역적 삽입반응으로 인하여 흑연의 exfoliation이 진행된다. 유기전해액으로 ethylene carbonate(EC)를 사용하면 이러한 문제점은 해결되지만, EC의 어는점이
