Description

Technical Field

[0001] The present invention relates to the technical field of lithium batteries, and in particular to a lithium battery with good high temperature resistance effect. Background Art

[0002] A lithium battery is a battery that contains lithium in its electrochemical system. It is a rechargeable battery that mainly relies on the movement of lithium ions between the positive and negative electrodes to work. A lithium battery mainly consists of a positive electrode, a negative electrode, a diaphragm and an electrolyte. The positive electrode is the positive electrode material coated on an aluminum foil, and the negative electrode is the negative electrode material coated on a copper foil. The diaphragm is used to isolate the positive and negative electrodes to prevent electrons from passing through, while allowing lithium ions to pass smoothly. The electrolyte plays a role in conducting lithium ions. During the discharge process of a lithium battery, lithium ions pass through the diaphragm from the negative electrode to the positive electrode, and electrons return from the negative electrode through an external circuit to the positive electrode to form an electric current. The charging process of a lithium battery is the opposite of this. Lithium batteries have the advantages of long service life, strong power storage capacity and green environmental protection, and have been applied to all aspects of life.

DETAILED DESCRIPTION

[0031] The present invention is further described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

A square hole 11 is opened in the middle of the upper end of the box cover 6. A T-shaped lifting plate 12 is inserted into the T-shaped hole 11, and the protective component 5 is installed at one end of the T-shaped lifting plate 12.

When the lithium battery body 2 works for a long time and generates a lot of heat When the heat is discharged, the heat is dissipated through the heat dissipation component 3. When the temperature sensor 16 detects that the temperature in the placement box 1 is too high, the signal is transmitted to the integrated control panel 15. The integrated control panel 15 controls the start of the ventilation component 4 to accelerate the heat dissipation speed of the lithium battery body 2. The heat dissipation effect is good, thereby improving the high temperature resistance of the lithium battery body 2.

When in use, the wind direction of the exhaust fan 401 at the bottom of the storage box 1 is the same as that of the exhaust fan 401 in the box cover 6. The air outlet duct 407 and the air inlet duct 408 are installed below and above the heat dissipation fins 303. When the lithium battery body 2 generates a large amount of heat after working for a long time, the heat is first transferred to the U-shaped heat pipe 302 through the heat dissipation base 301, and the U-shaped heat pipe 302 transfers the heat to the heat dissipation fins 303 for heat dissipation. When the temperature sensor 16 detects that the temperature in the storage box 1 is continuously too high, the signal is transmitted to the integrated control panel 15, and the integrated control panel 15 controls the exhaust fan 401 and the semiconductor cooling sheet 403 at the bottom of the storage box 1 to start, and the external The cold air generated by the air and semiconductor refrigeration plate 403 is transported to the installation groove 10, and then transported to the first ventilation cavity 404 and the second ventilation cavity 405 through the ventilation pipe 406, and then the cold air is blown onto the heat dissipation fins 303 through the air outlet pipe 407 to cool the heat dissipation fins 303. At the same time, the exhaust fan 401 in the box cover 6 is started, and the generated hot air is transported to the first ventilation cavity 404 and the second ventilation cavity 405 through the air inlet pipe 408, and then transported to the external environment through the installation groove 10. The heat at the upper end of the lithium battery body 2 can also be discharged through the air inlet pipe 408, so as to quickly dissipate the heat of the lithium battery body 2, and the heat dissipation effect is good. The dustproof net 402 plays a dustproof role.

[0035] like Fig. 9 and Fig.10As shown, T-shaped limit plates 29 are fixedly installed on both sides of one end of the mounting plate 9, a buffer pad 30 is fixedly installed on one end of the T-shaped limit plate 29, and one end of the buffer pad 30 is in contact with the lithium battery body 2.

At this time, the spring 507 is slightly squeezed. When the lithium battery body 2 is collided and shaken by external force, the buffer pad 30 at one end of the T-shaped limit plate 29 buffers the lithium battery body 2 laterally and longitudinally. The deformation force generated by the spring 507 and the buffer airbag 503 buffer the impact force and inhibit the lithium battery body 2 from moving upward.
