Abstract:
(EN) A nonaqueous electrolyte battery comprises: a positive electrode containing manganese dioxide and a carbon material; a negative electrode containing lithium or a lithium alloy; a nonaqueous electrolyte; and a container that houses the positive electrode, the negative electrode, and the nonaqueous electrolyte, wherein in the spectrum measured by implementing Raman spectroscopic analysis on the positive electrode using an argon laser of wavelength 514.5 nm, the average value of a peak intensity ratio ID/IG of a peak intensity ID that appears near 1330 cm–1 and a peak intensity IG that appears near 1580 cm–1 satisfies the relationship 0.5 ≤ ID/IG ≤ 1.3, and a mass ratio M2/M1 of a mass M1 of the positive electrode and a mass M2 of the nonaqueous electrolyte satisfies a relationship of 0.22 ≤ M2/M1.
(FR) L'invention concerne une batterie à électrolyte non aqueux comprenant : une électrode positive contenant du dioxyde de manganèse et un matériau carboné ; une électrode négative contenant du lithium ou un alliage de lithium ; un électrolyte non aqueux ; et un récipient qui loge l'électrode positive, l'électrode négative et l'électrolyte non aqueux, dans le spectre mesuré par la mise en œuvre d'une analyse spectroscopique Raman sur l'électrode positive à l'aide d'un laser argon de longueur d'onde de 514,5 nm, la valeur moyenne d'un rapport d'intensité de crête ID/IG d'une intensité de pic ID qui apparaît à proximité de 1330 cm–1 et une intensité de pic IG qui apparaît à proximité de 1580 cm–1 satisfait la relation 0,5 ≤ ID/IG ≤ 1,3, et un rapport de masse M2/M1 d'une masse M1 de l'électrode positive et d'une masse M2 de l'électrolyte non aqueux satisfait une relation de 0,22 ≤ M2/M1.
