非水電解質二次電池
Document Type and Number:
Japanese Patent JP5858295
Kind Code:
B2
Abstract:
According to the present invention, a nonaqueous electrolyte secondary battery that includes a positive electrode, a negative electrode and a nonaqueous electrolyte is provided. The positive electrode has an operation upper limit potential of 4.3 V or more based on metal lithium and includes a positive electrode active material and an inorganic phosphate compound that has ion conductivity. The inorganic phosphate compound is in a particle state. A ratio of particles having a particle size of 20 μm or more is 1% by volume or less when an entirety of the inorganic phosphate compound is set to 100% by volume. Further, a ratio of particles having a particle size of 10 μm or more may be 10% by volume or less when an entirety of the inorganic phosphate compound is set to 100% by volume.
