Embodiment Construction

[0014] The lithium battery of the present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings.

[0015] For the convenience of description, this embodiment takes a ring-shaped stacked lithium / manganese dioxide battery as an example for illustration.

[0016] Such as figure 1 with figure 2 As shown, the lithium battery 100 includes an annular casing and a cell inside the annular casing. The casing mainly includes an annular body 10 and a cover 20 welded together, and an annular false cover 30 connected with the cover 20 . The cover 20 is provided with a plurality of electrode columns 21 which are insulated and connected to the cover 20 and electrically connected to the dummy cover 30 and the battery core. The cell mainly includes an electrolyte (not shown), and an annular negative lithium sheet 40 , a separator 50 , a positive electrode 60 , a collector ring 70 and an insulating sheet 80 arranged in the body...

Abstract

The invention relates to a lithium battery, in particular to a ring-shaped lithium battery. The lithium battery comprises a shell body and an electric core positioned in the shell body. The shell body is composed of a ring-shaped body and a cover body which are fixedly connected, wherein the cover body is provided with at least one through-hole; an electrode column positioned in the at least one through-hole is sealed by insulating materials; the electrode column is electrically connected with the electric core. The invention provides the lithium battery which has a ring-shaped body in outer structure; the ring-shaped lithium battery can be sleeved directly on column-shaped or long and thin electrical equipment, such as automobile valves; and the lithium battery is connected with a circuit board, which provides power for the electrical equipment. The invention has convenient and reliable use and small occupied area. The lithium battery with a ring-shaped structure not only is conveniently connected with the electrical installation, but also has efficient dissipation of heat energy generated in battery operation due to the ring structure and large heat dissipation areas, thus increasing safety performance of the battery.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to an annular lithium battery. Background technique [0002] Due to its high operating voltage, high energy density, low self-discharge, and long life, lithium batteries are ideal energy sources for long-life and high-reliability instruments and meters. Because of their wide operating temperature range, they are also the preferred supporting power source for automotive electronics. [0003] In terms of the shape and structure of batteries, the common ones are cylindrical lithium batteries, square lithium batteries, and button lithium batteries. Lithium batteries with different shapes and structures are suitable for different application fields. Lithium batteries with existing structures are inconvenient to be applied to columnar or slender electrical appliances. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide ...
