12v lithium battery is a lithium battery pack composed of 3 or 4 lithium batteries in series. The capacity of the battery is determined by the capacity of the single cell and the number of cells connected in parallel. It is a new type of safety and environmental protection. rechargeable battery.
12V lithium battery classification
12V lithium batteries are divided into 12V lithium ion batteries, 12V lithium iron phosphate batteries, 12V cylindrical lithium batteries, and 12V polymer lithium batteries according to different materials and packages.
1. 12v lithium-ion battery
12V Li-Ion batteries are connected in series with 3 or 4 Li-Ion batteries. The combined battery pack, the capacity of the battery is determined according to the capacity of a single cell, or the capacity of the batteries connected in parallel, is a new type of safe and environmentally friendly battery.
Battery capacity
There is no standard capacity, which is determined according to the specific requirements of electrical appliances or equipment. The general capacity is: 2200mah, 5AH, 10Ah, and some electric vehicles have a capacity of 20AH or 50AH. The more batteries are connected in parallel, the greater the capacity.
Volume
The volume of the 12V lithium battery should be determined according to the capacity of the battery, and there is no uniform specification. The larger the battery capacity, the larger the volume.
Weight
Many devices now require lithium batteries with large capacity and light weight, such as electric vehicles, which used to use lead-acid batteries in the past. Now many electric vehicles have become lithium batteries, because lithium batteries have large capacity, light weight and small size.
Charge and discharge current
The charging and discharging current of the lithium battery is determined according to the power of the device. On the basis of constant voltage, the greater the power of the device, the greater the current that needs to be output.
2. 12V lithium iron phosphate battery
The 12V lithium iron phosphate battery is a battery pack composed of four lithium iron phosphate cells connected in series. The lithium iron phosphate cell is a lithium battery with lithium iron phosphate (LiFePO4) as the positive electrode material. The nominal voltage is 3.2V.
12V lithium iron phosphate battery advantages
12V lithium iron phosphate battery has a long life. Under the same conditions, lithium iron phosphate batteries can be used for 7 to 8 years.
Safe to use. The 12V lithium iron phosphate battery has undergone strict safety tests and will not explode even in a traffic accident.
Fast charging. Using a special charger, the battery can be fully charged after 40 minutes of 1.5C charging.
The 12V lithium iron phosphate battery is resistant to high temperature, and the hot air value of the 12V lithium iron phosphate battery can reach 350 to 500 °C.
The 12V lithium iron phosphate battery is green, non-toxic, non-polluting, has a wide range of raw material sources and is cheap.
3. 12V polymer lithium battery
The polymer lithium battery is developed on the basis of the liquid lithium ion battery. Its positive electrode and negative electrode materials are the same as the liquid lithium ion battery, but it uses gel electrolyte and aluminum plastic film as the outer packaging. It is called lithium polymer battery, also known as polymer lithium battery.
The 12V polymer lithium battery has a nominal voltage of 12V and is widely used in digital products, power tools, special wearable devices and other fields.
12V polymer lithium battery advantages
higher energy density
better security
Flexible design and customizable shape
good discharge characteristics
Protection plate design is simple
12V lithium battery price
The price of 12V lithium battery is mainly composed of three parts: battery cell, protection plate and shell. At the same time, due to the power consumption and current of the electrical appliance, the material of the connecting piece between the cells (conventional nickel sheet, formed nickel sheet , copper-nickel composite sheet, jumper, etc.) selection will affect the cost, and different connectors (such as plugs, ranging from ten yuan to thousands of yuan) may also have a greater impact on the cost, and different PACK processes will also affect the cost.
12V lithium battery pack
The 12V lithium battery pack is a lithium battery pack composed of 3 or 4 lithium batteries connected in series, and several lithium batteries are connected in parallel. Therefore, the capacity of the 12V lithium battery can be customized.
Common capacity of 12V lithium battery pack
4Ah, 5Ah, 7Ah, 8Ah, 9Ah, 10Ah, 12Ah, 17Ah, 18Ah, 20Ah, 30Ah, 40Ah, 50Ah, 100Ah, 200Ah, etc.
12VDC lithium battery
The 12V DC lithium battery is converted by a step-up/step-down circuit to stabilize the output voltage of the lithium battery at about 12V to meet the use of constant voltage working equipment. It is a standard DC battery with universal and easy compatibility. Change some of its characteristics to meet the use of different electrical equipment.
12V lithium battery application field
Lighting industry: solar street lights, solar insecticidal lights, solar garden lights, solar energy storage power, etc.;
Power field: power tools, robots, AGV, vacuum cleaners, electric sprayers, RC fields, etc.;
Consumer electronics: Bluetooth audio, loudspeaker fields, LED lamps and various electronic equipment, etc.;
Energy storage field: communication base stations, data centers, home energy storage, wind and photovoltaic energy storage, etc.;
Special fields: medical equipment, security power, special equipment, etc.
Factors affecting the price of 12V lithium battery
Batteries
Lithium batteries include lithium manganate (3.6V), lithium cobalt oxide (3.7V/3.8V), nickel cobalt lithium manganate (3.6V), lithium iron phosphate (3.2V), lithium titanate depending on the positive electrode material. (2.3V/2.4V) and other battery cells of various material systems, the voltage platform, safety factor, cycle times, energy density ratio, operating temperature, etc. of the cells of different material systems are different, so the price will also be different. different.
Brand
Different lithium battery brands have obvious price differences, mainly because the quality (safety, consistency, stability, production process, etc.) of each brand of batteries is basically proportional to the price.
Capacity
When the voltage of the 12V lithium battery is determined, the larger the capacity, the higher the cost and the higher the price.
Protection board quality and circuit design
High-quality lithium batteries use high-quality electronic components and protection boards, as well as multiple protection circuit designs, which not only improve the charging and discharging circuit, but also have multiple designs such as constant temperature and constant voltage, overcharge, overdischarge, overcurrent, and short circuit. You and your equipment create a safe environment to use, so the price will be affected by these two factors.
Because the lithium battery market is very chaotic, many lithium battery manufacturers insure the price at will, and the quality is not necessarily guaranteed, so everyone must look for the quality and pay attention to the quality when purchasing. Welcome to Mylion factory to customize the required lithium battery.
