Abstract

The invention relates to the technical field of ultrathin batteries, in particular to a novel ultrathin battery. The novel ultrathin battery comprises a positive electrode substrate, a negative electrode substrate, a positive electrode granular material, a negative electrode granular material, a diaphragm, a positive tab and a negative tab, wherein the positive electrode particle material and thenegative electrode particle material are respectively coated on the positive electrode base material and the negative electrode base material, the positive electrode base material and the negative electrode base material are separated by using a diaphragm, and the positive electrode base material, the negative electrode base material, the positive electrode particle material, the negative electrode particle material, the diaphragm, the positive electrode lug and the negative electrode lug are packaged by using aluminum plastic films and are filled with electrolyte. The invention further provides a preparation process of the novel ultrathin battery, the production process is simplified, the processing is simple, the production consumables are small, the yield is high, the production cost islow, the battery capacity is high, the appearance is smooth and not easy to soften, the hardness meets the high-strength use requirement, and the novel ultrathin battery has market prospects and is suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of ultra-thin batteries, in particular to a novel ultra-thin battery and a preparation process thereof. Background technique [0002] With the continuous development of battery technology, people put forward more requirements for the performance of batteries. The ultra-thinning of batteries is an important development direction of batteries. [0003] At present, those skilled in the art have realized the ultra-thin design of the battery, and proposed various implementation methods. However, the production and manufacture of ultra-thin batteries in the prior art still has the following defects, such as complex production process, difficult processing, large battery production consumables, high production cost, low battery capacity, insufficient capacity, low appearance flatness, and due to thin thickness Lead to defects such as the battery is prone to softening and hardness is not enough. [0004] The abov...
