Description
技术领域technical field
本实用新型涉及扣式电池的技术领域，尤其是一种成本低，接触性好的扣式电池负极片。The utility model relates to the technical field of button batteries, in particular to a button battery negative plate with low cost and good contact performance.
背景技术Background technique
传统的扣式电池的负极片的生产包装工艺是先将连接网点焊在负极金属壳体的内底面，然后将锂片压合在连接网上，可是连接网一般不会十分贴合的焊接在负极金属壳体内底面上，也就会导致与连接网压合的锂片不会十分贴合金属壳体内底面，进而导致整个电池的接触性不好；同时，大量的使用连接网，成本相对较高，而且连接网还占据了电池内部的有效成分，让负极的有效释放性减弱。The production and packaging process of the negative plate of the traditional button battery is to first spot-weld the connecting network on the inner bottom of the negative metal shell, and then press the lithium sheet on the connecting network, but the connecting network is generally not welded to the negative electrode very well. On the inner bottom surface of the metal shell, the lithium sheet pressed with the connecting grid will not fit the inner bottom surface of the metal shell very well, which will lead to poor contact of the entire battery; at the same time, a large number of connecting grids are used, and the cost is relatively high , and the connecting network also occupies the active components inside the battery, which weakens the effective release of the negative electrode.
实用新型内容Utility model content
本实用新型要解决的技术问题是：为了解决上述背景技术中的问题，本实用新型提供一种成本低，接触性好的扣式电池负极片。The technical problem to be solved by the utility model is: in order to solve the above-mentioned problems in the background technology, the utility model provides a button battery negative plate with low cost and good contactability.
本实用新型解决其技术问题所采用的技术方案是：一种扣式电池负极片，具有由锂带冲压的锂块。The technical solution adopted by the utility model to solve the technical problem is: a negative plate of a button battery, which has a lithium block punched by a lithium belt.
进一步地，锂带为方形长带。Further, the lithium strip is a rectangular long strip.
进一步地，锂块为圆形。Further, the lithium block is circular.
本实用新型的有益效果：本实用新型的扣式电池负极片中取消了连接网，使得成本大大地降低，同时生产工序得到了简化，效率得到了提高，扩大了电池内部的有效空间，负极的有效释放性提高了10％，锂块与负极金属壳体内底面的接触性更好。Beneficial effects of the utility model: the utility model cancels the connecting net in the negative plate of the button battery, so that the cost is greatly reduced, and at the same time the production process is simplified, the efficiency is improved, and the effective space inside the battery is expanded. The effective release is increased by 10%, and the contact between the lithium block and the inner bottom surface of the negative metal casing is better.
