NON-AQUEOUS ELECTROLYTE SOLUTION BATTERY AND COMMUNICATION DEVICE

A non-aqueous electrolyte solution battery includes a positive electrode containing manganese dioxide and a carbon material; a negative electrode including one of lithium and a lithium alloy; a non-aqueous electrolyte solution; and a container configured to accommodate the positive electrode, the negative electrode, and the non-aqueous electrolyte solution. In a spectrum that is measured by performing Raman spectroscopic analysis with respect to the positive electrode by using argon laser at a wavelength of 514.5 nm, an average value of peak intensity ratios I/Iof an intensity Iof a peak appearing in the vicinity of 1330 cmto an intensity Iof a peak appearing in the vicinity of 1580 cmsatisfies a relationship of 0.5≤I/I≤1.3.
