Abstract
Charge-discharge characteristics of the Li-ion battery with the anode of 94.5% mass content of active material and 4% mass content of CMC/SBR(mass ratio 3 : 5), or 96.5% mass content of active material and 2.0% or 2.5% mass content of acry-lonitrile multi-copolymer LA133 were compared. The cell expansion,cycle performance and safety performance were investigated. The cell with the anode of 2.5% LA133 had the best comprehensive performance,exhibited a energy density of 455 Wh/L at the current of 1.00 C (3.0 ~ 4.2 V), 10.44% higher than the cell with the anode of 4.0% mass content of CMC/SBR. The capacity retention was more than 91% after 300 cycles at the current of l.00 C (3.0~4.2 V) .Environment and safety test showed that the battery had high environment adaptability and reliability.关键词
