Non-aqueous electrolyte battery, positive electrode for non-electrolyte battery, negative electrode for non-aqueous electrolyte battery, separator for non-electrolyte battery, electrolyte for non-aqueous electrolyte and separator for non-electrolyte battery

摘要

Suppresses gas generation inside the battery and achieves high safety. Between a positive electrode in which a positive electrode active material layer containing a positive electrode active material is formed on a positive electrode current collector, a negative electrode in which a negative electrode active material layer containing a negative electrode active material is formed on a negative electrode current collector, and the positive electrode and the negative electrode And a separator impregnated in the separator, and at least one of the positive electrode, the negative electrode, the separator, and the electrolyte includes a heteropolyacid and / or a heteropolyacid compound as an additive.
