Embodiment Construction

[0023] Such as image 3 , 4 As shown, the improvement of the present invention to the lithium battery is to replace the collector tube with the multi-collector connected with the metal collector ring 14 at one end of the collector needle or the collector post 15, and the collector needle or the collector post of the multi-collector Insert it into the positive electrode package 5.

[0024] When the positive electrode package uses a carbon package hollow structure, the carbon package specifications are 25.0mm in outer diameter, 10.0mm in inner diameter, and 46.0mm in height, and the positive electrode current collector is used figure 2 The structure of the positive electrode current collecting cylinder shown is that the steel collecting cylinder has a diameter of 11.0mm and a length of 46.0mm (collecting cylinder for short), and the use of Figure 4 The structure of the multiple current collectors of the positive electrode shown has a current collector needle (15) with a diam...

Abstract

The invention relates to a lithium battery, which is made up of a shell, a bottom film, metal lithium negative electrode, side film, a positive electrode cover, a upper cover film, flow gathering barrel, sealed pin, connecting nickel band, top cover, a glass insulator, a positive end. the character lies in: one end of the flow gathering pin or the gathering pole is connected to a metal flow gathering ring, forms the multiple flow gathering body to replace the flow gathering barrel, the pin or the pole are inserted into the positive electrode cover. The uncontrollable change of positive electrode size and shape can be avoided when inserting the flow gathering barrel into the positive electrode cover, the uniformity and controllability of the battery can be improved, and the performance is improved.

Description

technical field [0001] The invention relates to the battery field, in particular to the improvement of the lithium battery structure. technical background [0002] The long-life high-energy lithium battery has a service life of more than 10 years. The uniformity and reliability requirements of this type of battery performance are very high. Therefore, in the battery production process, the quality of each spare part must be strictly controlled, so that the performance data of all spare parts and materials are in a controllable, reliable and predictable state. [0003] Existing cylindrical lithium batteries with metal lithium (Li) as the negative electrode, such as Li / SOCl 2 , Li / SO 2 , Li / MnO 2 and other types of batteries, generally figure 1 structure shown. figure 1 The fully sealed battery structure shown in , consists of the bottom film 2 at the bottom of the battery, the metal lithium negative electrode 3 between the inner surface of the cas...
