摘要： In order to charge a rechargeable lithium-cobalt cell having a capacity C, the charging current undergoes several cycles (Z1, Z2) and each cycle (Z1, Z2) comprises high-current and low-current phases of different length. During a low-current phase, the current value is I1=C*0.090 (wherein I1 is in amperes and C is in ampere hours), and during a high-current phase, the current value is I2=C*0.165. It has been shown that the cell can thereby be charged at higher energy density and aging effects can thereby be reduced.
