An electrochemical device that ensures good safety

Abstract

The invention discloses an electrochemical device with good safety, which comprises a housing and a storage battery body. The storage battery body is arranged inside the housing, and four evenly distributed third connecting rods are hinged on the four side walls of the housing. , the other end of the third connecting rod is hinged with a fourth T-shaped slider, and the fourth T-shaped slider is slidably connected with a vertically arranged side plate, and the side plate is provided with two vertically arranged second sliders. The fourth T-shaped sliders are all slidably connected in the second chute, wherein a second spring is connected between the two fourth T-shaped sliders, and the second spring is located in the second chute, and the side plate The bottom ends of each are slidably connected with two symmetrically arranged second T-shaped sliders. The device has a reasonable structure and a novel design, can protect the inside and outside of the storage battery, prevent the storage battery from catching fire or exploding due to a short circuit caused by severe impact or vibration, and has high safety.

[0002] Now people's life is inseparable from the use of electricity, and various battery products have been fully integrated into our lives. The interior of the battery is equipped with anode and cathode electrodes, and organic electrolytes or polymer electrolytes are filled in the space between the cathode and anode. Electricity is generated by the oxidation and reduction reactions of the cathode and anode with the electrolyte solution. If the battery is overcharged, excess metal ions are extracted from the cathode and inserted into the anode. As a result, metal ions with very high reactivity are deposited on the On the surface of the anode, the cathode also becomes thermally unstable, and the organic solvent used as the electrolyte undergoes a decomposition reaction. The resulting sharp exothermic reaction reduces the power generation efficiency of the battery. Over time, the battery will catch fire or explode, and when the battery is damaged When there is a relatively severe vibration or impact from the outside world, the cathode and anode in the battery will be partially short-circuited, and a very large amount of heat will be generated locally around the short-circuited part, which will shorten the battery life. Therefore, it is necessary to avoid such rapid heating inside the battery. For this reason, we Propose an electrochemical device that ensures good safety
