LITHIUM SECONDARY BATTERY NEGATIVE ELECTRODE COMPONENT MATERIAL AND METHOD OF ITS MANUFACTURE |
摘要 |
Affords high-stability, high-safety lithium secondary batteries of high energy density and superlative charge/discharge cyclability, in which shorting due to the growth of dendrites from the metallic-lithium negative electrode is kept under control. A lithium secondary battery negative-electrode component material, formed by laminating onto a substrate a metallic lithium film and an inorganic solid-electrolyte film, the lithium secondary battery negative -electrode component material characterized in that the inorganic solid-electrolyte film incorporates lithium, phosphorous, sulfur, and oxygen, and is represented by the compositional formula noted below. aLi.cndot.bF.cndot.cS.cndot.dO (Li= lithium; P: phosphorous; S: sulfur; O: oxygen), wherein the ranges of the atomic fractions in the composition are: 0.20 <= a <= 0.45; 0.10 <= b <=0.20; 0.35 <= c <= 0.60; 0.03 <= d <= 0.13; (a+b+c+d=1). |
