Beschreibung
Zusammenfassung:	FIELD: electric engineering. ^ SUBSTANCE: negative electrode is suggested for secondary chemical current source with nonaqueous electrolyte, including current collector and structure of active material, formed on one or both its surfaces, containing electro-conductive material with low capacity for connection to lithium, at least on one side of current collector, while aforementioned active material structure contains from 5 to 80% mass of active material particles, containing material with high capacity for forming connections with lithium. Such a structure of active material preferably includes a layer of active material, containing particles of active material, and surface covering layer, which is present on a layer of active material. ^ EFFECT: improved cyclic characteristics. ^ 5 cl, 10 dwg, 7 tbl, 103 ex
