[0041] The present invention will be further described below in conjunction with the embodiments.

[0042] Embodiment 1:

[0043] In order to solve the problem that the existing ribbon solid-state batteries generally lack external force protection mechanisms when in use, and lack internal power-on and power-off protection structures, which leads to the battery being easily damaged during use and is not conducive to use, the following solution is disclosed. For details, please refer to Figure 1-Figure 4The inside of the battery protective shell 1 is also fixedly connected to a protective air cushion 112, and the protective air cushion 112 is provided with multiple groups.

The inside of the battery protective shell 1 is also provided with a battery element 122, and the battery element 122 is provided with multiple groups. The multiple groups of battery elements 122 are connected to the inside of the battery protective shell 1 through the mounting groove 121, and the multiple groups of battery elements 122 are connected to each other through the conducting wires. The inside of the battery protective shell 1 is also fixedly connected to a conductive electrode 123, and the conductive electrode 123 is provided with two groups, and one group of conductive electrodes 123 is connected to the battery protective shell 1. The positive electrodes of one group of battery elements 122 are connected, and the conductive electrode 123 of the other group is connected to the negative electrode of the battery element 122 of the other group. The conductive electrodes 123 of the two groups are respectively connected to the two corresponding wires 22. Two groups of reset springs 13 are provided, and the other end of the reset spring 13 is fixedly connected to a copper sheet 131. The inside of the battery protective shell 1 is also fixedly connected to an electromagnet 132, and the electromagnet 132 is electrically connected to the wire 22. The bottom of the copper sheet 131 is fixedly connected to a fixed magnet 133, and the fixed magnet 133 matches the electromagnet 132. When the device is used, the flexible pad 11 on the outside of the battery protective shell 1 and the upper protective shell 12 can play a role in the inside of the battery protective shell 1. The flexible pad 11 and the upper protective shell 12 are both made of carbon fiber, which has high hardness and light texture, so that the overall weight of the device is reduced, and the arrangement of the aluminum wire mesh 111 and the protective air cushion 112 can make the battery element 122 inside the battery protective shell 1 have a good protective effect.

When the external power is cut off, the electromagnet 132 loses power. Under the action of the reset spring 13, the copper sheet 131 is reset and re-contacted with the battery element 122, so that the excess current is diverted, avoiding the occurrence of damage to the battery element 122 due to excessive power-off current, thereby achieving a good protection effect on the battery element 122 and the battery protective shell 1, and improving the use effect.
