[0002] Lithium battery is a common rechargeable battery that uses lithium metal or lithium compounds as the positive electrode material and stores and releases electrical energy through the migration of lithium ions between the positive and negative electrodes. Lithium batteries have the advantages of high energy density, light weight, long life and low self-discharge rate, and are widely used in mobile devices, electric vehicles and energy storage systems. There are many types of lithium batteries, such as lithium-ion batteries, lithium polymer batteries and lithium iron batteries. The working principle of lithium batteries is to convert electrical energy through the embedding and de-embedding of lithium ions in the positive electrode material during the charging and discharging process.

[0003] For some large electric equipment, such as electric cars, electric bicycles and other tools for daily life and production, energy storage devices with higher voltage or larger capacitance are usually required. Therefore, lithium batteries are usually used in parallel or in series with multiple battery modules. Traditional lithium batteries are mostly connected in series or in parallel through external wires, which is inconvenient during assembly.

When assembling the lithium battery, the insertion strip 2 of the first lithium battery is inserted into the inner side of the slot 3 of the second lithium battery, so as to realize the assembly of the lithium battery, thereby forming a lithium battery pack.

[0028] See also Figures 1 to 6A slot 4 is provided at the upper end of the lithium battery body 1, and the slot 4 is annularly distributed at the four corners of the upper end surface of the lithium battery body 1. An L-shaped conductive bar 6 is provided on the upper surface of the lithium battery body 1, and the L-shaped conductive bar 6 is centrally symmetrically distributed. The L-shaped conductive bar 6 is fixedly installed on the upper surface of the lithium battery body 1 by screwing a nut on the electrode column 18. The L-shaped conductive bar 6 can be made of, but not limited to, copper metal. The L-shaped conductive bar 6 is electrically connected to the electrode column 18. A conductive block 5 is embedded in the inner side of the slot 4. A connecting thread column 17 is fixedly provided on the upper surface of the conductive block 5. The conductive block 5 is fixedly installed on the lower surface of the L-shaped conductive bar 6 by screwing a nut on the connecting thread column 17. The conductive block 5 can be made of, but not limited to, copper metal. The conductive block 5 is fixedly installed at both ends of the lower surface of the L-shaped conductive strip 6, and the conductive block 5 is electrically connected to the L-shaped conductive strip 6. A blind hole 10 is opened at one end of the conductive block 5. A conductive component and a spring 11 are arranged inside the blind hole 10. The conductive component can be made of, but not limited to, copper metal. The conductive component is slidably arranged inside the blind hole 10. One end of the spring 11 abuts against the inside of the blind hole 10, and the other end of the spring 11 abuts against one end of the conductive component. The spring 11 is always in a compressed state. An electric wire 12 is arranged inside the blind hole 10, and one end of the electric wire 12 is fixedly connected to the inner wall of the blind hole 10, and the other end of the electric wire 12 is fixedly connected to one end of the conductive component. The electric wire 12 acts as a bridge, so that the electric block 5 and the conductive component are electrically connected through the electric wire 12.

[0029] See also Figures 2 to 4 The conductive component is composed of a sliding column 7, a neck column 8 and a connecting plate 9. The sliding column 7 is slidably connected inside the blind hole 10. The spring 11 abuts against one end of the sliding column 7. The electric wire 12 is fixedly connected to one side of the sliding column 7. The neck column 8 is fixedly arranged at the end of the sliding column 7 away from the spring 11, and the diameter of the neck column 8 is smaller than the diameter of the sliding column 7, so that the sliding column 7 slidably connected inside the blind hole 10 can slide within a certain range. The connecting plate 9 is fixedly arranged at the end of the neck column 8 away from the sliding column 7, and the diameter of the connecting plate 9 is larger than the diameter of the neck column 8. A connecting groove 15 is opened on one side of the conductive block 5. A toothed baffle 16 is fixedly provided on the edge of the connecting groove 15. When the lithium battery is assembled, the spring 11 will push the conductive component slidably connected to the inside of the blind hole 10, so that the connecting plate 9 at one end of the conductive component of the first lithium battery extends into the inside of the connecting groove 15 of the second lithium battery, and the connecting plate 9 abuts against the inside of the connecting groove 15. The toothed baffle 16 fixedly provided on the edge of the connecting groove 15 abuts against the side edge of the connecting plate 9 close to the neck column 8, so that the connecting plate 9 extending into the inside of the connecting groove 15 will not fall off from the inside of the connecting groove 15, thereby ensuring a stable electrical connection between the two lithium batteries.

[0030] See also Figures 2 to 6The upper surface of the conductive block 5 is provided with a plug hole 14, and an isolation plate 13 is inserted into the inner side of the plug hole 14. Before the lithium battery is assembled, the side of the connecting plate 9 away from the neck column 8 abuts against the side of the isolation plate 13. At this time, the conductive component is retracted inside the conductive block 5. When assembling the lithium battery, the plug 2 of the first lithium battery is inserted into the inner side of the slot 3 of the second lithium battery, and the structural column of the battery can be rotated out. Then, the isolation plate 13 inserted into the inside of the plug hole 14 is pulled out. At this time, the isolation plate 13 no longer resists the conductive component slidably connected to the inside of the blind hole 10. Under the action of the restoring force of the spring 11, the spring 11 pushes the conductive component slidably connected to the inside of the blind hole 10, so that the neck column 8 The connecting plate 9 fixed at one end extends into the interior of the connecting groove 15. At this time, the toothed baffle 16 fixed at the edge of the connecting groove 15 resists the edge of the connecting plate 9, so that the connecting plate 9 is stably abutted against the interior of the connecting groove 15, thereby making the two lithium batteries stably electrically connected, thereby improving safety. By setting a connecting component composed of a conductive block 5, a spring 11 and a conductive component, when assembling the lithium battery, it is only necessary to unplug the corresponding isolation plate 13 to realize the series and parallel connection of the lithium batteries. There is no need to connect additional wires, thereby reducing the risks brought by connecting additional wires and further improving safety, thereby making the lithium battery easier to assemble during use and making the composition of the lithium battery more efficient and convenient.
