Problems solved by technology

[0004] The existing lithium-ion batteries built into tablet computers are one whole or several large batteries or battery packs connected together. Compared with bendable screens, they belong to a steel structure and cannot be bent, so they cannot meet practical use. Require
Although the above-mentioned technical problems can be solved by adopting multiple batteries connected in series and parallel, the assembly structure of multiple batteries in series and parallel requires a large number of peripheral structures, resulting in a waste of space structure, resulting in a battery energy density that cannot meet the needs of electrical appliances. Actual demand

Abstract

The invention discloses a bendable lithium ion battery which comprises a packaging foil, a plurality of cells, a soft connecting wire and electrolyte poured in the packaging foil. The packaging foil is internally provided with a plurality of grooves which are used for internally accommodating the cells. The soft connecting wire is connected to the anodes and cathodes of the cells and leads the total anode and cathode ends out of the packaging foil. Compared with the prior art, the bendable lithium ion battery provided by the invention can be bended to a certain extent due to structural characteristics or even folded by one half, so that the bendable lithium ion battery can be adaptive to special demands of electronic products such as bendable screens.

Description

technical field [0001] The invention belongs to the field of batteries, and more specifically, the invention relates to a bendable lithium ion battery. Background technique [0002] With the development of modern society and the enhancement of environmental protection awareness, more and more devices, such as mobile phones, laptop computers, power tools and electric vehicles, choose to use rechargeable secondary batteries as power sources, providing rechargeable secondary batteries It provides a broad space for its application and development. Lithium-ion batteries have become one of the most widely used rechargeable secondary batteries because of their advantages such as high energy density, high open circuit voltage, long cycle life and environmental protection. [0003] At present, mobile electronic products such as mobile phones, tablet computers, and notebook computers have more and more functions, and their sizes are becoming thinner and thinner. While continuously me...
