A mobile phone lithium-ion battery suitable for low temperature environment

Abstract

The invention discloses a mobile phone lithium ion battery suitable for low temperature environment, comprising a lithium ion battery body, an annular cavity is opened on the side wall of the lithium ion battery body, and a friction ring is slidably connected to the inner wall of the annular cavity, and the annular cavity is slidably connected to the inner wall of the annular cavity. A heat preservation board is embedded on the inner wall of the cavity, a strip groove is formed on the side wall of the lithium ion battery body, and a driving device for driving the friction ring to move up and down is installed in the strip groove. In the invention, the capacitor and the helical coil are connected in series through the temperature control sheet under low temperature to form an LC series circuit, and an oscillating current with periodic changes in size and direction is generated in the LC series circuit, so that there is an iron core inside. The spiral coil generates a magnetic field whose magnitude and direction are constantly changing, and can push the magnetic friction ring to slide up and down in the annular cavity. Discharge in a low temperature environment will damage the battery or mobile phone.

Description

technical field

[0001] The invention relates to the technical field of machinery, in particular to a mobile phone lithium-ion battery suitable for a low temperature environment. Background technique

[0002] The working principle of the lithium-ion battery is that the internal electrolyte changes through a chemical reaction, and a potential difference occurs between the positive and negative electrodes to generate current. At present, most of the batteries used in electronic products such as mobile phones are lithium-ion batteries.

[0003] Among them, the ambient temperature of the battery is a key factor affecting the performance of the battery. In low temperature areas such as northern my country, the outdoor temperature in winter can often reach -30 °C. In this low temperature environment, the electrolyte moves quite slowly, so It affects the transfer activity of lithium ions between the positive and negative electrodes, resulting in a smaller discharge current of the ba...
