| 摘要 |
An electrical device, such as an electrochemical cell which comprises a conductive anode and cathode capable of mutual electrochemical reaction and separated by a solid electrolyte comprising: a) a matrix of cross-linked polymer main chains, optionally having side-chains linked to the main chains, which side chains comprise polar groups free from active hydrogen atoms, b) a polar aprotic liquid dispersed in the matrix, and c) an ionised ammonium or alkali metal salt dissolved in the matrix and/or liquid, characterised in that the liquid is present as at least 300 parts by weight per 100 parts by weight of the matrix, a cathode therefor, the electrolyte per se, and processes for the preparation of the electrolyte and the cathode. <IMAGE> |
