With the popularization of Apple computers and smart phones, the consumer market has more and more requirements for mobile phones, especially lithium batteries for smart phones. In addition to the data electronics industry, lithium batteries are also widely used in new energy vehicles, mobile communication base stations and other venues. Lithium batteries have greater energy density, that is, under the same volume, rechargeable batteries include a large amount of output power than NiMH rechargeable batteries. Therefore, like the current rechargeable batteries, they are generally all lithium batteries, which are light in weight and small in size, and can consider a certain volume regulation.
The 12v lithium-ion battery pack has high safety, long life and high low temperature efficiency. Main application areas: solar light energy storage batteries and solar street lights. The price of 12v lithium-ion battery pack is mainly composed of three parts: lithium battery cell, lithium battery protection board and shell. The selection of formed nickel sheets, copper-nickel composite sheets, jumpers, etc. will affect the cost. Different connectors (such as aviation plugs, ranging from ten yuan to thousands of yuan) have a greater impact on the cost. The PACK process also affects cost.
12v lithium ion battery pack cell: lithium battery according to the different cathode materials, lithium manganate (3.6V), lithium cobalt oxide (3.7V/3.8V), nickel cobalt lithium manganate (3.6V), lithium iron phosphate (3.2 V), lithium titanate (2.3V/2.4V) and other lithium batteries of various material systems, the lithium batteries of different material systems, their voltage platform, safety performance, cycle times, energy density ratio, working environment temperature, etc. Not the same, so the price will also be different.
12v lithium-ion battery pack brand: Different lithium battery brands have obvious price differences. The key is that the quality (safety, consistency, stability, production process, etc.) of each brand of lithium batteries is basically related to the price. proportional.
12v lithium-ion battery pack capacity: when the voltage of a 12v lithium-ion battery pack is determined, the larger the capacity, the higher the cost and the higher the price.
Lithium battery protection board quality and circuit principle: A good-quality 12v lithium-ion battery pack uses high-quality electronic components and lithium battery protection boards. At the same time, there are multiple protection circuit principles, which not only improve the charging and discharging circuit, but also have constant temperature and constant voltage, over Multiple designs such as charging, over-discharging, over-current, and short-circuiting create a safe environment for you and your equipment, so the price will be affected by these two factors.
