摘要： A positive electrode active material (1) disclosed herein includes a Ni content lithium complex oxide (2) containing 70 mol% or more of nickel relative to the total of metal elements other than lithium, and a boron element (4). The Ni content lithium complex oxide (2) is in a form of a secondary particle in which primary particles (2a) are aggregated and has a porosity of 2% or more and 10% or less, and inside the secondary particle, a larger space than an average cross-sectional area of the primary particles (2a) does not exist. The boron element (4) is contained by 0.5 to 3 mol% when the total of metal elements of the Ni content lithium complex oxide (2) is 100 mol%.

摘要： 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.
