Abstract
The invention provides an arc-shaped battery cell and an arc-shaped lithium battery. The arc-shaped battery cell comprises a battery cell body, a positive tab and a negative tab, wherein the battery cell body comprises a positive plate, a first hot melt adhesive coating layer, a diaphragm, a second hot melt adhesive coating layer and a negative plate which are sequentially stacked, the first hot melt adhesive coating layer and the second hot melt adhesive coating layer are adhered to the diaphragm, the positive plate is adhered onto the first hot melt adhesive coating layer, the negative plate is adhered onto the second hot melt adhesive coating layer, the battery cell body is of an arc-shaped structure, the positive tab is welded on the positive plate, and the negative tab is welded on the negative plate. The arc-shaped battery cell is easy to form, relatively good in surface smoothness and relatively good in shaping effect.
Description
technical field [0001] The invention relates to the technical field of lithium ion batteries, in particular to an arc-shaped battery cell and an arc-shaped lithium battery. Background technique [0002] Since the large-scale production of lithium-ion batteries was realized in the 1990s, it has rapidly occupied many battery fields due to its incomparable advantages such as small size, large capacity, non-toxic environmental protection, and long service life. on electronic products. With the renewal and development of science and technology, the market has higher and higher requirements for portable electronic products, and the requirements for its power supply have also increased accordingly. The space becomes an irregular shape. With the further development of electronic products, smart watches and smart bracelets are coming out one after another. Since they are worn on the wrist when in use, the equipped battery needs to be set according to the use status of the product, ...
