Description

Technical Field

[0001] This utility model relates to the field of lithium battery technology with positive and negative adapter plates, and in particular to a lithium battery with positive and negative adapter plates. Background Technology

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the positive / negative electrode material and a non-aqueous electrolyte solution. Due to the highly reactive chemical properties of lithium metal, the processing, storage, and use of lithium metal require very high environmental standards. With the development of science and technology, lithium batteries have become mainstream. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium-ion batteries. The main principle of the discharge process of lithium batteries is to convert chemical energy into electrical energy.

[0003] However, lithium batteries usually need to be assembled before use. Welding equipment is used to weld the output end of the lithium battery, and the assembly process is relatively complicated, which makes it difficult for lithium batteries to be disassembled and recycled.

[0004] In a lithium battery with a positive and negative adapter plate, published on January 3, 2025 (authorization announcement number CN 222300812 U), although it claims to achieve solderless assembly of the customer product and the lithium battery as a whole, thus solving the problem of the cumbersome assembly process of existing lithium batteries, soldering is still required. For example, two solder pads are used to solder the tabs. However, soldering is prone to problems such as cold solder joints, leading to poor contact and affecting its normal use.

[0005] Therefore, in this utility model application, the applicant has carefully researched a lithium battery with a positive and negative electrode adapter plate to solve the above problems. Utility Model Content

[0012] The positive electrode ear is electrically connected to a third conductive button, which is fastened and fixed to another first conductive button and connected in a conductive manner.

[0013] As a preferred embodiment, the battery body includes a housing and a battery cell located inside the housing. The housing has a receiving cavity with a rear opening. The positive electrode tab and the negative electrode tab are electrically connected to the battery cell, respectively. The battery cell is located inside the receiving cavity. The negative electrode tab and the second conductive button both extend out of the housing. The positive electrode tab protrudes from the front end face of the housing. The adapter plate is installed at the rear opening.

[0014] As a preferred embodiment, the positive electrode tab is electrically connected to a third conductive button via a conductive sheet.

[0015] As a preferred embodiment, the conductive sheet has an L-shaped structure, including a vertical conductive portion extending in the up-down direction and a horizontal conductive portion extending in the front-back direction.

[0017] As a preferred embodiment, the adapter plate is detachably installed at the rear opening.

[0018] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0019] Its main feature is that the two tabs and the adapter board are electrically connected by conductive buttons, which achieves complete solderlessness, is easy to assemble, and avoids poor contact caused by poor soldering, which would affect the normal use of lithium batteries.
