Abstract
The present invention aims to suppress gas generation during charge/discharge cycles, storage, and the like when a group IV to VI oxide, such as a lithium titanate, is used as a negative electrode active material. A non-aqueous electrolyte secondary battery includes a positive electrode having a positive electrode collector and a positive electrode mixture layer formed thereon, a negative electrode having a negative electrode collector and a negative electrode mixture layer formed thereon, and a fluorine-containing non-aqueous electrolyte. In the positive electrode mixture layer, a lithium transition metal oxide and a phosphoric acid compound are contained. In the negative electrode mixture layer, a group IV to VI oxide is contained which contains at least one type of element selected from a group IV element, a group V element, and a group VI element of the periodic table and which has a BET specific surface area of 2.0 m2/g or more.
