Description

technical field [0001] The invention relates to the application field of batteries, in particular to a novel ultra-thin battery and a preparation method 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 and so on. [0004] The above technical defects seriously limit the development of ultra-thin batteries, and become an obstacle to further popularization and applicat...
