Abstract

The invention discloses a novel lithium battery as well as a manufacturing process and application thereof, which belong to the field of batteries. The novel lithium battery comprise a cylindrical battery main body, the diameter d of the battery main body is more than or equal to 18 and less than 21 mm, and the height h of the battery main body is more than or equal to 650 mm. The battery main body comprises a shell, a battery core body arranged in the shell and electrolyte filling the shell, and a clamping ring is integrally formed in an inner cavity at the bottom of the shell. Compared withthe traditional 18650 battery, the novel lithium battery provided by the invention has the advantages that the performance is improved by setting battery capacities with different sizes, and meanwhile, the performance application on an electric tool is met.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a novel lithium battery and its manufacturing process and application. Background technique [0002] Power tools are widely used in construction, housing decoration, automobiles, machinery, electric power, bridges, gardening and other fields because of their convenient portability, simple operation, and diverse functions, and they can greatly reduce labor intensity and improve work efficiency. . [0003] Cylindrical lithium-ion batteries have become the mainstream of power tool batteries because of their consistent model, light structure, small size, light weight, and environmental protection. However, ordinary 18650 cylindrical lithium-ion batteries cannot meet the requirements of electric impact drills and electric wrenches. This type of power tool generates high-intensity vibration during operation, and the traditional 18650 battery can no longer meet the application requirements of...
