`(S4)ALL-SOLID LITHIUM SECONDARY BATTERY
`
`(57Abstract
`
`PROBLEM TO BE SOLVED: To provide an all-solid iithium secondary battery having
`
`excellent charge-discharge characteristics.
`
`SOUUTION: This aill-solid lithium secondary battery comprises a positive electrode 4
`
`that comprises a positive electrode layer 2 which includes a pasitive electrode active
`
`material containing Li element, and a positive electrode current collector 3; a
`
`negative electrode & that cornprises a negative electrode layer 6 cantaining a
`
`negative electrode active material 5, and a negative electrode current collector; and
`
`a solid electrolyte 9 consisting of compound which is sandwitched between the
`
`pasitive electrode layer and the negative electrode current collector, and
`
`represented by a compound having the formula: LIS-2XMXIni-Y¥MY46 (wherein M
`
`and M' are metal elements, 2 is halogen, X and ¥ independently satisfy Q2x<1.5, 0
`
`<Y¥<1). Electric potentials of the negative electrode active material 5 against Li are
`
`lass than 0.7 V on average.
