A lithium ion storage battery, comprising a lithium ion cell (1), a positive electrode terminal (2), a positive/negative electrode insulation sheet (3), an electrical connector (4) and a housing (5) used as a negative electrode, wherein the lithium ion cell (1) is arranged in the housing (5), the electrical connector (4) is arranged between the lithium ion cell (1) and the shell (5) and used for connecting electrodes of internal cells, the positive electrode terminal (2) is installed on one end of the lithium ion cell (1), the positive electrode terminal (2) and the housing (5) are isolated and packaged by means of the positive/negative electrode insulation sheet (3), a circuit board (6) is arranged between a battery positive/negative electrode and the lithium ion cell (1), a voltage/current control and overcharge/over-discharge protection circuit is integrated on the circuit board (6), and the battery positive/negative electrode is connected to the lithium ion cell (1) by means of the voltage/current control and overcharge/over-discharge protection circuit. The voltage/current control and overcharge/over-discharge protection circuit can adjust the voltage of the lithium ion battery to be 1.5V/1.2V, the shape and size of the housing (5) are designed according to requirements, and the lithium ion battery can substitute a traditional dry battery. A same port can be adopted for the charging and discharging ports, and no additional charging circuit is required. |
