Abstract

The present invention discloses an identification-free polar chargeable battery, which comprises a battery cell(2), an outer cover(23) for enclosing the battery cell(2), 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 anode of the battery is respectively protruding arranged at a first anode(11) and a second anode(12) which are arranged in the middle parts of the two end faces of the battery. A cathode(6) is arranged on the sidewall of the battery with protruding parts. Therefore, the chargeable battery can provide power supply to the electric devices not only through the first anode(11) and the cathode(6), but also through the second anode(12) and the cathode(6). The outer cover(23) also can be provided with a signal chip(13), the starting and ending terminals of which are respectively positioned at the two end faces of the battery. The chargeable battery always can obtain normal power supply, no matter how the appliances are arranged. Therefore, the present invention has fairly convenient application and also is more beneficial for the senior and the children.

Description

technical field

[0001] The invention belongs to the technical field of rechargeable batteries, and in particular relates to a secondary battery whose positive and negative electrode structures are improved so that the polarity does not need to be identified during use. Background technique

[0002] At present, in the field of battery technology and application, batteries are used as power sources for electronic and electrical products. When installing batteries into electrical products, it is usually necessary to follow the "+, -" poles on the battery and compare the positive and negative poles marked on the battery box of the electrical product. Installation and use can ensure normal operation. If the label is unclear or the ambient light is insufficient or even in a dark environment, it is particularly inconvenient to place the battery; sometimes due to negligence, accidentally reverse the polarity of the battery, which will not only cause the electrical product to fail to ...
