FIELD: chemical current supplies; negative plates of lithium-ion cells.
SUBSTANCE: novelty is that negative plate of lithium-ion cell has current collector whose surface carries active layer based on mixture of modified graphite and acetylene black taken in proportion of 80 : 20 to 95 : 5, respectively. Content of modified graphite in the form of film, 0.05 - 0.1 μm thick, having specific surface area of 1500 to 2000 m2/g is 3 to 10 mg.
EFFECT: reduced irreversible capacitance of plate.
