Abstract

The invention provides a lithium battery allowing the internal temperature and pressure to be detected, belonging to the technical field of battery manufacturing. According to the lithium battery, thetechnical problems that the internal temperature and pressure of an existing lithium battery cannot be conveniently detected, and the like are solved. The lithium battery comprises a battery cell, abase, a cap and a cylindrical shell, wherein the base is fixedly arranged at the lower end of the shell, the cap is fixedly arranged at the upper end of the shell, the battery cell is inserted into the shell, a PCB is arranged at the bottom of the base, and a temperature sensor and a pressure sensor are respectively arranged on one side, facing towards the inside of the shell, of the PCB; and a data transmission wire is connected to the PCB, a through hole is formed in the base, and one end of the data transmission wire penetrates through the through hole and stretches out of the shell. By arranging the temperature sensor and the pressure sensor in the lithium battery, the temperature and the pressure in the shell can be detected in real time, and related numerical values can be transmitted to a detection instrument, so that the internal pressure and temperature parameters of the battery can be timely and accurately evaluated by an operator.

Description

technical field [0001] The invention belongs to the technical field of battery production design and relates to a lithium battery capable of detecting internal temperature and pressure. Background technique [0002] Lithium batteries have the advantages of high safety, large specific capacity, and low self-discharge rate, and have been widely used in the fields of digital electronics and power batteries. During the use of lithium batteries, heat will be generated, which will cause the temperature of the battery to rise, and the impact of temperature on the battery is very important; when the temperature of the battery reaches above 50 ° C, the stability of the interface of the internal materials of the battery will decrease, and the side reaction of the electrolyte will decrease. Increase, the cycle stability of the battery will decrease, and the battery life will be shortened. When the temperature rises further, the battery material will decompose, which will intensify the...
