TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Process: The assembling of lithium-containing cathode, anode, separator material and electrolyte involves providing a partially or totally assembled alkali ion battery comprising cathode, anode and electrolyte, where the cathode comprises a material chosen from non-delithiated and partially or totally delithiated cathode materials, and adding polymerizable monomer to electrode and/or electrolyte of partially or totally assembled alkali ion battery. The production of alkali ion battery involves providing alkali ion battery comprising lithium-containing cathode, anode and electrolyte, partially or totally delithiating the cathode by charging the battery at least partially, partially and/or totally disassembling the battery, reassembling the battery using delithiated cathode by adding a monomer to the delithiated cathode and/or to the electrolyte, and polymerizing monomer by oxidizing monomer in the reassembled battery by applying an external charge to the battery and/or to the reassembled battery. The monomer is polymerized on and/or in the matrix of the cathode and/or working electrode, to form polymer-cathode composite material and/or composite polymer-working electrode. The production of alkali ion battery further involves sealing the partially assembled alkali ion battery, the pre-assembled or disassembled alkali ion battery and/or the electrochemical device comprising the electrolyte with the monomer. The electrolyte, cathode and anode are selected so that and/or interact such that, upon charging, a polymer is formed from monomer.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Compounds: The cathode or working electrode comprises a material chosen from lithium-containing layered, olivine or spinel-related solid materials, or lithium-containing compound (a) of formulae: AMY', AMOXO4 and AN'2O4.
