Lithium battery case with good heat dissipation effect

Abstract

The invention discloses a lithium battery case with a good heat dissipation effect. The lithium battery case comprises a battery body, wherein a positive plate is arranged at the left side of the bottom of an inner cavity of the battery body; a negative plate is arranged at the right side of the bottom of the inner cavity of the battery body; the top of the battery body is fixedly connected with a protective shell; a positive terminal and a negative terminal are arranged at two sides of the top of the battery body separately; and the tops of the positive terminal and the negative terminal penetrate through the protective shell and extend to the top of the protective shell. Through arrangement of the protective shell, an opening, a first shell, a second shell, a vent board, a spring, a vent circular board, a rubber disk and a vent hole, heat generated by the battery during working can be timely discharged, the battery can work at good temperature, the work efficiency of the battery can be effectively improved, the probability of an overheating problem of the battery is greatly reduced and the service life of the battery is prolonged.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a lithium battery casing with good heat dissipation effect. Background technique [0002] Lithium battery is a primary battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. It is different from rechargeable batteries. Lithium-ion batteries are different from lithium-ion polymer batteries because the chemical properties of lithium metal are very active. , so that the processing, storage and use of lithium metal have very high environmental requirements, so lithium batteries have not been used for a long time. Lithium-ion batteries have entered a large-scale practical stage. Lithium-ion batteries will generate a lot of heat during use. Traditional lithium-ion batteries cannot dissipate heat well, which will not only affect the working efficiency of the battery, but may also Because the internal temperatur...

[0002] Lithium battery is a primary battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. It is different from rechargeable batteries. Lithium-ion batteries are different from lithium-ion polymer batteries because the chemical properties of lithium metal are very active. , so that the processing, storage and use of lithium metal have very high environmental requirements, so lithium batteries have not been used for a long time. Lithium-ion batteries have entered a large-scale practical stage. Lithium-ion batteries will generate a lot of heat during use. Traditional lithium-ion batteries cannot dissipate heat well, which will not only affect the working efficiency of the battery, but may also Because the internal temperature of the battery is too high, the battery damage problem occurs, which greatly shortens the service life of the battery.
