Abstract
A nonaqueous electrolyte battery includes a negative electrode and a positive electrode. The negative electrode includes a negative electrode current collector and a negative electrode active material having a lithium ion absorption potential of 0.4 V (vs. Li/Li+) or more. The negative electrode current collector is made of aluminum or an aluminum alloy. The positive electrode includes a positive electrode current collector and a positive electrode active material. The positive electrode current collector has a total area and specific capacitance larger than those of the negative electrode current collector, and is made of aluminum or an aluminum alloy.
