What type of mobile power use?

- Oct 24, 2016 -

First, lithium cobalt oxide (LiCoO2)

Lithium cobalt oxide (LiCoO2), commonly known as liquid lithium-ion battery, common form had 18650 and square shapes. 18650 battery is 18 mm in diameter, height 65 mm of cylinder batteries (larger version looks like the 5th battery), is widely used in laptop batteries, due to laptop batteries, universal, now on the market for more than 60% of mobile power and 18650 battery. In commercial lithium ion battery is basically layered structure of LiCoO2 lithium cobalt oxide cathode material. The theoretical capacity of 274mAh/g, the actual capacity is about 140mAh/g, there have also been reports the actual capacity has reached 155mAh/g. Cathode materials for the higher operating voltage (voltage of 3.7V of the average), the charge voltage stability, small size, high energy, good performance, high conductivity, the production process is simple, easy to manufacture and so on.

For your secret analysis: mobile power supply 3 battery types

Main advantages: maturity of the technology, a wide range of applications, compact.

Main drawback: service life cycle in about 300 times, low security, poor resistance to overcharge, not suitable for high rate discharge, waste pollution to the environment.

Second, nickel, cobalt and manganese (LiNiCoMnO2)

NI-co-MN ternary materials (LiNiCoMnO2), is a kind of polymer lithium-ion battery, a common form of square bale shape (lithium cobalt oxide can also make the box shape, but after forming hard, pinch can be distinguished by hand). Ternary materials as the Smartphone is developing rapidly in popularity in the past two years, areas of use is also increasing. Ternary composite cathode materials for precursor product, is based on nickel, cobalt and manganese salts as raw material, manganese and nickel ratio can be adjusted according to the actual need, ternary material relative to lithium cobalt oxide cathode battery battery safety, service life is high lithium cobalt oxide, at 500 times the cycle life.

Main advantage: diversity in size, using a very wide range, not explosive, high safety factor.

Main drawback: higher prices, waste pollutes the environment, current performance is weak.

Third, the lithium iron phosphate (LiFePO4)

Lithium iron phosphate (LiFePO4) and the multiplicity of ferroelectric, the previous biggest difference between two types of batteries is the positive pole of the battery joined the iron. Li-Fe has just started in recent years, is a potential material. Its safety performance and cycle life is unmatched by any other material and most important of these is the battery specification. 1C charge/discharge cycle life up to 2000 times, single-cell charging voltage 30V, no burn, puncture and not explode.

Lithium iron phosphate cathode materials for large-capacity battery pack more in series to meet electric needs of frequent charge and discharge. And with nontoxic, pollution-free, safe performance and sources of raw material, long life and other advantages, is ideal for next-generation lithium-ion batteries cathode materials. Iron with large capacity electric buses, base stations and big UPS for energy storage applications, mobile power, AA batteries just beginning to test the waters of which mass production, which makes ferroelectric gradually in the bulk-UPS, small storage batteries, lawn lamp, are widely used in power tools.
