LITHIUM ION CONDUCTIVE COMPOSITE MATERIAL CONTAINING AT LEAST ONE POLYMER AND LITHIUM ION CONDUCTIVE PARTICLE, AND MANUFACTURING METHOD OF LITHIUM ION CONDUCTIVE BODY FROM COMPOSITE MATERIAL

摘要

To provide a lithium ion conductive composite material having practically higher particle filling degree than one conventionally capable of being used, and containing at least one polymer and lithium ion conductive particle.SOLUTION: The problem is solved by a lithium ion conductive composite material containing at least one polymer and lithium ion conducive particle, the particle has spheroidicity Ψ of at least 0.7, the composite material contains at least 20 vol.% of particle when polydispersity index PI of particle diameter distribution is less than 0.7, or the composite material contains at least 30 vol.% of particles when the polydispersity index PI of particle diameter distribution is in a range of 0.7 to less than 1.2, or the composite material contains at least 40 vol.% of particle when the polydispersity index PI of particle diameter distribution is over 1.2.SELECTED DRAWING: None
