Abstract

The invention discloses a rechargeable micro shell lithium ion battery structure and a processing technology thereof. The battery comprises a sealing assembly and a winding body, wherein an electrolyte is arranged in the sealing assembly, and the winding body is soaked into the electrolyte; the sealing assembly consists of a shell, a cover cap and a seal ring, the shell and the cover cap are made of metal materials respectively, and the seal ring realizes insulation between the shell and the cover cap; the winding body is provided with a positive lug and a negative lug, the positive lug is electrically connected with the cover cap, and the negative lug is electrically connected with the shell. The disadvantage that disposable button cells in the current market cannot be recharged for utilization is abandoned, and a rechargeable micro shell lithium ion battery is creatively provided. The battery is simpler in structure, lower in cost and higher in space utilization rate.

Description

technical field [0001] The invention relates to the technical field of hard-shell batteries, in particular to a structure and a preparation method of a rechargeable miniature hard-shell lithium-ion battery. Background technique [0002] With the rise of wearable products, the diversification and miniaturization of battery products are becoming more and more obvious. The miniaturization of products will increase the requirements for the manufacturing process level and product design level. When the product is miniaturized to a certain extent, there will be a sharp increase in the requirements for the process manufacturing level, and there will be a big change in the product design concept, and there will even be a decisive change. Opposite change. [0003] For a long time in the past, due to the limitation of the manufacturing level and design concept, the secondary micro-lithium-ion rechargeable battery has not been able to achieve industrial production, and even experiment...
