All-solid lithium secondary battery
专利汇可以提供All-solid lithium secondary battery专利检索，专利查询，专利分析的服务。并且PURPOSE: To obtain a high-energy density secondary battery which is normally operated at an ordinary environmental temperature by using a specific stratified structure oxide for a positive electrode active material, lithium or a lithium alloy for a negative electrode active material, and a specific compound for an electrolyte.
CONSTITUTION: A stratified structure oxide expressed by the formula I is used for a positive electrode active material, lithium or a lithium alloy is used for a negative electrode active material, and a compound expressed by the formula II is used for an electrolyte. In formulas I and II, x+y=1, y=0.03-0.5, z=0.0-1.6, A is GeO
2 or SiO, and N=P(E)
2 is oligoethylene oxypolyphosphasen having sulfone groups optionally arranged in segments expressed by formulas III and IV or its mixture. X is anion, M is a metal of the group I and the group II, R and R' are independent methyl or the like, (h) and (k) mean average repetition numbers of the ethyleneoxy unit and are real number values in ranges 0≤h≤15 and 0≤k≤22.5, and (a) means the ratio between LiX and N=P(E)
2 and is the real number value about 0.001-4. A high-energy density secondary battery is obtained.
