2. Guangdong Thermal Precision Technology Co., Ltd. was established in 2021 and is located in Meizhou City, Guangdong Province. It is a company mainly engaged in the manufacturing of computers, communications and other electronic equipment.
The cell types of industrial lithium batteries include 18650 cells, polymer cells and lithium iron phosphate cells.
1, 18650 battery core
This cathode material has a high operating voltage (the tenAverage operating voltage is 3.7V), stable charging and discharging voltage, small size, high specific energy, good cycle performance, high conductivity, and production process Simple and easy to carry out.
Main advantages: mature technology, wide application range, small size. Main disadvantages: service life is about 300 times, poor safety performance, poor overcharge resistance, not suitable for high-rate charging and discharging, and pollute the environment after being scrapped .
In the mobile power supply market, 18650 batteries used in power supplies include: imported 18650 batteries, domestic 18650 batteries and dismantled 18650 batteries.
2. Polymer battery core
Main advantages: diversified volume, very wide use range, not easy to explode and s factorhigh security. Main disadvantages: higher price, environmental pollution after disposal, and poor high-current charging and discharging performance.
Polymer batteries are not divided into domestic, imported or disassembled batteries like 18650 batteries. They are divided into three grades, namely A, B and C.
3. Lithium iron phosphate battery
Main advantages: 2000 cycle lifespan, high current charge and discharge, low internal resistance and less heat, safe, environmentally friendly and non-toxic. Main disadvantages: It is expensive, has not yet been used on a large scale in the field of digital products and is little known among consumers.
Detailed Information
Lithium batteries generally come in two shapes: cylindrical and square. The internal structure of the battery is a spiral winding structure, with a minsulating material made of very thin and highly permeable polyethylene film separated between the positive and negative electrodes. The positive electrode includes a current collector composed of lithium cobalt oxide (or lithium nickel cobalt manganate, lithium manganate, lithium iron phosphate, etc.) and a foil 'aluminum.
The negative electrode consists of a current collector made of graphitized carbon material and copper foil. The battery is filled with an organic electrolyte solution. In addition, a safety valve and PTC element (used in some cylindrical types) are installed to protect the battery from damage caused by abnormal conditions and output short circuits.
The voltage of a single lithium battery is 3.7V (the positive electrode of lithium iron phosphate is 3.2V), and the capacity of the battery cannot be infinite. Therefore, lithium batteriesSingle iums are often connected in series or parallel. .To meet the requirements of different occasions.
