Abstract

A winding type curved surface battery comprises a winding core which comprises a positive plate, a negative plate and a diaphragm; the battery also comprises a shell matched with the roll core and wraps the roll core; the diaphragm is arranged between the positive plate and the negative plate; the positive plate, the negative plate and the diaphragm are wound to form a roll core; the positive plate and the negative plate are connected with adapter foils, and the other end of each adapter foil is connected with a tab; the roll core can be bent into a curved surface shape with radian along the length direction of the positive plate and the negative plate in a spreading state; and the adapter foil can be bent, so that the tabs can extend in the length direction of the spread state of the positive plate and the negative plate.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a wound-type curved surface battery. Background technique [0002] With the improvement of people's pursuit of quality of life, products in the field of sports and health and fashion are popular, and the demand for wearable products such as sports bracelets, heart rate monitoring bracelets and smart watches has exploded, and the market is in urgent need of a ring-shaped battery. For the power supply of such products, there are many wristband batteries with laminated structure in the market, which are complicated in manufacturing process, low in efficiency and high in cost. Generally, the battery tabs of the general winding type are usually arranged on the side of the winding direction of the pole piece (the length direction of the pole piece in the unfolded state), and in order to adapt to the ring-shaped product, the battery usually needs to be bent into a suitable arc, and th...
