Abstract

The purpose of this invention is to provide a nonaqueous electrolyte secondary battery exhibiting high outputting property in a low-temperature environment, said nonaqueous electrolyte secondary battery being a lithium ion secondary battery which uses a lithium manganese composite oxide as the positive electrode active material and a lithium titanium composite oxide as the negative electrode active material. The nonaqueous electrolyte secondary battery has a positive electrode active material which contains a lithium manganese composite oxide containing lithium and manganese as constituent elements, a negative electrode active material which contains a lithium titanium composite oxides containing lithium and titanium as constituent elements, and a separator which contains inorganic particles.

Description

technical field [0001] The present invention relates to a nonaqueous electrolyte secondary battery, and particularly relates to a nonaqueous electrolyte secondary battery exhibiting high output characteristics in a low temperature environment. Background technique [0002] Lead storage batteries are widely used as backup power sources for industrial equipment and commercial equipment, and as power sources for starters of automobiles. [0003] In recent years, the development of nickel-metal hydride batteries or lithium-ion secondary batteries to replace lead storage batteries used for backup power sources has been active. By replacing the lead storage battery with a nickel metal hydride battery or a lithium ion secondary battery, miniaturization of a power supply due to high energy density and reduction of environmental pollution due to non-use of lead can be expected. [0004] Currently, there is no tendency to replace lead storage batteries used as power sources for start...
