ABSTRACT:
Electrochemical elements in thin layers comprising a stack of thin layers, successively a copper layer, a catholyte, a separator, a lithium layer, the catholyte and the separator being formed by a gel comprising more particularly formal or polyvinylic butyral, reticulated or otherwise and impregnated with a solvent such as propylene carbonate or N-methyl-pyrrolidone saturated with an ionically conductive salt such as ammonium perchlorate. A variant consists in forming the separator with a gel of reticulated polymer basically containing polyvinylidene fluoride and a mineral charge such as magnesia.
