FIELD: electrochemistry.SUBSTANCE: lithium-aluminium anodes are used in lithium current sources (LCS), which are used as power sources for memory long-term storage and supporting; in complex process equipment, operating at given program; in systems of fluid and gas flow rate metering and analysis; in medical technology as most reliable and compact. Promising direction in production of chemical current sources and, in particular, LCS, is creation of anodes of film structure. Disclosed is lithium-aluminium anode, which includes base containing powder of lithium-aluminium alloy, characterised by that polymer film from secondary cellulose acetate (SCA) filled with aluminium powder and LiAl alloy powder formed with lithium intercalation into polymer film filled with aluminium powder is used as base. LCS polymer base provides plasticity material enables variation of thickness of electrode, provides uniform distribution of lithium in layer and enables variation of electrochemical characteristics.EFFECT: technical result of invention is increased number of lithium-aluminium anode cycling.1 cl, 1 tbl, 3 ex |
