/Carbon-ceramic Composites, Electrode Comprising The Same And Secondary Battery Comprising The Electrode
Abstract
The present disclosure relates to a ceramic-carbon composite including a ceramic shell surrounding a hollow portion; and a carbon coating layer surrounding the ceramic shell, wherein the hollow portion is in a vacuum state, an electrode including the ceramic-carbon composite, and a secondary battery including the electrode. The ceramic-carbon composite of the present disclosure has excellent thermal barrier effect and electrical conductivity, and thus, when used in the electrode, non-ideal heat transfer between an electrode active material and an electrode current collector is blocked to prevent a thermal runaway phenomenon, to have an effect that can significantly improve safety of the secondary battery.
