Portable lithium battery

Abstract

The invention discloses a portable lithium battery which comprises a box body. A handle is arranged at the top end of the box body; the handle is arranged inside the box body in a penetrating mode and is fixedly connected with the box body by a bolt; a display is arranged at the end part of the box body; the display is embedded into the outer lateral surface of the box body and is adhered to the box body by glue; a prompting lamp is arranged at the bottom of the display; a cathode interface and an anode interface which are arranged in a straight line shape are arranged at the bottom end of the prompting lamp; columnar charging ports are formed at one sides of the cathode interface and the anode interface; universal rollers are arranged at the bottom of the box body; the universal rollers are arranged inside the box body in a penetrating mode and are fixedly connected with the box body by bolts; a rectangular box door is arranged at the tops of the universal rollers. According to the portable lithium battery, the display at one side of the box body can be used for displaying information, such as a current electricity quantity and a case whether the lithium battery needs to be charged or not, so that intellectualization is improved.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a portable lithium battery. Background technique [0002] The so-called "lithium battery" is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. The lithium metal battery was first proposed and studied by Gilbert N. Lewis in 1912. In the 1970s, M.S.Whittingham Proposed and began to study lithium-ion batteries. Due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the development of science and technology, now Lithium batteries have become the mainstream, and lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. [0003] However, the existing lithium batteries...

AI Technical Summary

Problems solved by technology

[0003] However, the existing lithium batteries use liquid lithium-ion batteries for power storage and discharge, and it takes a long time to charge them. Due to the many times of charging and overcharging, it is very easy to cause the lithium battery to explode, and the safety is low. Short cycle life, heavy weight, self-discharge, expensive, high production requirements, high cost, limited use conditions, high and low temperature use is dangerous, and its use function is too single
