AA battery. From the information about the square battery, we know that the square battery is an AA battery. The square lithium battery logo consists of 3 letters and 6 numbers. The square size can be designed arbitrarily, and the cylindrical pile cannot be designed. compared with. The limitations of the multi-pole tab welding process for cylindrical batteries are slightly worse than those for square multi-pole batteries. The chemical activity of square lithium battery corners is low, the energy density of the battery is easily degraded after long-term use, and the battery life is short.
Lithium metal batteries were first proposed and studied by Gilbert N. Lewis in 1912. In the 1970s, M. S. Whittingham proposed and began studying lithium-ion batteries . The chemical properties of metallic lithium being very active, the processing, storage and useation of metallic lithium are subject to very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the development of science and technology, lithium batteries have now become common.
Common rechargeable and non-rechargeable batteries include 3.6V rechargeable lithium-ion button cell (LIR series). ) and 3V rechargeable lithium-ion button cells (ML or VL Series). Non-rechargeable batteries include 3V lithium manganese button cells (CR series) and 1.5V alkaline zinc manganese button cells (LR series and SR series).
The code for button batteries generally has an R followed by a number. These numbers directly represent the diameter and thickness of the battery, such as CR3032 lithium button, which refers to a diameter of 30mm and a thickness of 32mm. Some special diameter and thickness codes, such as LR41, referto an alkaline battery, one. A diameter of 7.9mm and a thickness of 3.6mm, SR43 refers to the silver oxide battery, 11.6mm in diameter and 4.2mm in thickness.
Here are some common button batteries:
LTC-3PN and LTC-5PN are lithium battery models produced by Eaglepicher Battery (China) Co., Ltd. in the USA.
Square lithium battery (square lithium battery) is a battery. Lithium-ion batteries are divided into square lithium batteries (such as commonly used mobile phone battery cells) and cylindrical lithium batteries (such as 18650, 18500, etc.) according to their appearance. ) and button-type lithium batteries; aluminum-cased lithium batteries, steel-cased lithium batteries and soft-packaged batteries according to the outer packaging materials according to the positive electrode materials; they are divided into lithium cobalt oxide, iron phosphate and lithium, lithium manganate and lithium polymer.
New electric bikes include models using lithium batteries. The identification of secondary lithium batteries in the IEC standard is: ?
The identification of cylindrical lithium batteries is composed of 3 letters + 5 numbers.
