Abstract

The invention provides an L-shaped lithium ion battery and a formation method thereof. The battery comprises a battery cell, a shell coating outside the battery cell and an electrolyte filled in the shell, wherein the battery cell is manufactured by means of a laminating process and comprises an L-shaped positive plate, an L-shaped negative plate and an L-shaped diaphragm arranged between the L-shaped positive plate and the L-shaped negative plate. According to the L-shaped lithium ion battery and the formation method thereof provided by the invention, on the one hand, the capacity of the battery is increased effectively, so that the time of endurance is prolonged and the capacity of endurance of the battery is ensured; and on the other hand, the inflating problem of the battery is solvedthoroughly, so that the performance of the battery in a follow-up using process is ensured.

Description

technical field [0001] The invention relates to the technical field of lithium-ion batteries, in particular to an L-shaped lithium-ion battery and a formation method thereof. Background technique [0002] Lithium-ion batteries have been widely used in various fields because of their good capacity characteristics, power characteristics, cycle performance, self-discharge performance and safety characteristics. In recent years, wearable devices, smart phones and tablet computers have been widely used. At present, these devices basically use lithium-ion batteries as energy sources. However, due to the limited internal space, conventional circular and square lithium-ion batteries cannot be used. Make full use of its internal space, resulting in short cruising time of this type of equipment. For example, the battery life of a smart watch is about 24 hours. If more functions are turned on, the power consumption will increase, so that the user has to charge twice a day to use it no...
