  • Non-aqueous electrolyte solution battery and communication device
    Patent number: 11811048
    Abstract: 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 ID/IG of an intensity ID of a peak appearing in the vicinity of 1330 cm?1 to an intensity IG of a peak appearing in the vicinity of 1580 cm?1 satisfies a relationship of 0.5?ID/IG?1.3.
    Type: Grant
