PURPOSE:To provide the subject electrolyte useful for all solid cells, etc., and capable of depressing the crystallization of the electrolyte at low temperature and holding the non-flowability thereof at high temperature by employing a medium comprising a specific phosphazene polymer containing a specific compound. CONSTITUTION:The objective electrolyte is made of a medium comprising a phosphazene polymer having segments of formulas I-VI (M is monovalent element selected from Li, Na, K, copper, silver and H; (h), (k) are the average repeat number (practical number value) of ethyleneoxide units under conditions of 0<=h<=22.5, 0<=k<=15; (l), (m), (n) are 0, positive integer within 3<=(l+m+n)<=20000) in an arbitrary arranged structure or a mixture thereof and containing a polyalkyleneoxide, poly(methacrylic acid oligoalkyleneoxide), polyester, polyimine, polyacetal compounds or a mixture thereof and a Li salt. |
