Chargeable battery

Abstract

The present invention discloses a chargeable battery which comprises at least one battery cell(2), an outer cover(23) for enclosing the battery cell(2), the anode and cathode(8) of the battery, an electricity charging and discharging circuit comprising a protecting circuit of the electricity charging and discharging circuit. The electricity charging and discharging circuit is integrated into a circuit board(4) and is encapsulated into the outer cover(23) of the battery together with the battery cell(2). Wherein, the sidewall surface of the battery is concave provided with an electricity charging socket(3), the two terminals of which are respectively connected with the anode and cathode of the electricity charging and discharging circuit. Through combining the two anodes and cathodes at the two terminals of the battery, the rechargeable battery disclosed in the present invention can provide two power supply modes. Through adopting the rechargeable lithium battery structure, the invention has the advantages of convenient electric charging operation and taking, as well as compatible with the structures of various electric appliance products.

Description

technical field [0001] The invention belongs to the technical field of rechargeable batteries, and in particular relates to a secondary battery with an improved structure of a charging socket. Background technique [0002] Rechargeable battery is a kind of high energy density, high discharge voltage, light weight, small size and easy to carry. It is widely used in the fields of electronics, home appliances and IT products. When charging is required, the charging process should be completed through a specific charger. The charger usually includes a suitable battery box, which is positioned and electrically connected by spring compression. Since the battery box adopts spring compression, use Over time, the elasticity of the spring will deteriorate, the reliability of the connection will be reduced, and it is difficult to ensure normal operation for a long time. [0003] On the other hand, the general structure of the currently used battery is that one end of the battery is po...

Problems solved by technology

[0002] Rechargeable batteries are characterized by high energy density, high discharge voltage, light weight, small size, and portability. They are widely used in the fields of electronics, home appliances, and IT products. Generally, rechargeable batteries are used in When charging is required, the charging process must be completed through a specific charger. The charger usually includes a suitable battery box, which is positioned and electrically connected by spring compression. Since the battery box is pressed by a spring, the use Over time, the elasticity of the spring will deteriorate, which will reduce the reliability of the connection and make it difficult to ensure long-term normal operation

[0003] On the other hand, currently commonly used batteries generally have a positive pole at one end and a negative pole at the other end. There is only one power supply method, and there are various battery boxes in small appliances and IT products on the market. Therefore, a single power supply The battery of this type obviously cannot adapt to the needs of such structurally diverse electrical products, and its compatibility has defects.
