Influence of Water Mass Fraction on Performance of Lithium Ion Batteries
Abstract:
The influence of water mass fraction on the performance of Lithium-ion batteries was studied.The results show that the comprehensive electrochemical performance of Lithium-ion batteries is the best with the first discharging capacity (125±2) minutes at 300 mA,discharging time (48±3) minutes at 600 mA and 3.6 V cut-off voltage,resistance (38±3) mΩ,thickness (4.25±0.05) mm,capacity attenuation of 100 cycles (7.8±0.5)% when the water mass fraction is controlled within 0.015%.The experimental results were analyzed by the formation mechanism of negative SEI film and the reaction process of water in the electrolyte.
