    摘要: A non-aqueous electrolyte is disclosed, which comprises a non-aqueous solvent and a solute represented by the general formula(1): MBR1R2R3R4, wherein M is an alkali metal atom or an ammonium group and R1 to R4 are each independently electron withdrawing groups or electron withdrawing atoms bound to B where at least one of R1 to R4 is other than a fluorine atom. The solute has a thermal stability substantially equal to that of LiBF4 and an anion portion having a high electronegativity, and easily dissociates into ions. Therefore, a non-aqueous electrolyte containing this solute has a high ionic conductivity and is difficult to cause a generation of a gas or deterioration in characteristics due to the decomposition of the solute, which occurs during use at high temperatures or after storage at high temperatures.

    摘要: A polymeric solid electrolyte capable of conducting lithium ions which contains silylamide bonds in its polymer skeleton structure, for example, which is obtained by a method comprising subjecting a mixture of lithium silylamide and an organic compound having at least one carbon—carbon double bond to a polymerization in a dry atmosphere; and a lithium secondary cell using the polymeric solid electrolyte. The polymeric solid electrolyte is a “dry” polymeric solid electrolyte which contains counter ions forming lithium salts with lithium ions in its polymer skeleton structure and thus has a single ion electron conducting system wherein lithium ions alone are mobile ions, and hence has excellent conductivity, and further is easy to produce. The polymeric solid electrolyte can therefore be used for producing a novel lithium secondary cell which is an alternative for conventional lithium cells using an organic solvent and is safe and excellent in the capability of corresponding to a variety of shapes and has a high cell voltage.
