(JP10060152-A)      A hybrid electrolyte is prepared by impregnating a moulded high polymer porous body comprising a polymeric base material of crosslinked polymer segment and bubbles dispersed in the base material with an electrolytic solution selected from aqueous electrolyte or a solution of a non-aqueous solvent and liquid electrolyte until the porous body swells to a gel fraction of the polymeric material of 20-75%.    Also claimed are: (i) the production of the hybrid electrolyte by impregnating the polymeric material with the electrolytic solution to swell at an essentially non-swelling temperature but under pressure, with maintenance at this swelling temperature and pressure; (ii) the production of the hybrid electrolyte in which the moulded polymeric porous body made from vinylidene fluoride or acrylonitrile polymer is impregnated with the electrolytic solution at ambient pressure and 35C, and then the swollen material is heated at 80C, at normal pressure; (iii) a hybrid electrolyte that is made by one of the above processes; and (iv) the production of an electrochemical element by laminating the swollen and electrolyte-impregnated polymeric porous body with an electrode and maintaining at this temperature and pressure; or by laminating an electrode with a hybrid electrode mad with a process as described in (ii); or by laminating the electrode with a porous body before making the hybrid electrolyte by the process in (i) or (ii).    USE -   The hybrid electrolyte may be used to manufacture an electrochemical element (claimed) e.g. in primary and secondary lithium batteries, electrochemical sensors and photoelectric chemical devices.    ADVANTAGE -   The hybrid electrolyte has high ionic conductivity and improved high-temperature stability, and exhibits good adhesion when stuck to an electrode, without leakage. Because of its light weight and miniaturability, batteries made with it are especially suitable for mobile phones and PCs.
