Lithium batteries are currently divided into cylindrical lithium batteries, prismatic lithium batteries, polymer-ion batteries and lithium iron phosphate batteries. At present, cylindrical lithium batteries are mainly used in laptop batteries, and prismatic and lithium polymer batteries are mainly used in digital. products (mobile phones, digital cameras, tablets, etc.), while lithium iron phosphate batteries are mainly used for power or energy storage (such as electric vehicles).
There are two types of lithium batteries used in mobile devices. phones, usually lithium polymer batteries and aluminum-cased lithium-ion batteries. Generally speaking, most non-removable batteries use lithium polymer batteries, while most removable batteriess use aluminum-cased lithium-ion batteries. For example, all Apple products use lithium. Polymer batteries, and most of Samsung's mobile phones use square lithium batteries, and tablet computers mainly use lithium polymer batteries. Oppo's mobile phone batteries use both square lithium batteries and lithium polymer batteries.
< p>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. Since the chemical properties of lithium metal are very active, the processing, storage and use of lithium metal 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, piLithium batteries have now become common.
Common rechargeable and non-rechargeable batteries include the 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, refer to an alkaline battery, a. 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 cells:
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, lithium iron phosphate, lithium manganate and lithium polymer.
New electric bikes include models using lithium batteries. The identification of lithium secondary batteries in the IEC standard is: ?
The identification of cylindrical lithium batteries is composed of 3 letters + 5 numbers.
