What is the difference between lithium iron phosphate battery and 18650?
18650 battery brands are: LG, HG2, Samsung 25R , Sony VTC4, Lishen LISHEN, BYD, BAK, etc. ?
The theoretical battery life of the 18650 is 1,000 charge cycles. Due to their large capacity per unit density, most of them are used in laptop batteries. In addition, 18650 is widely used in various electronic fields due to its very good work stability.
Recommended brands:
1. LISHEN
Tianjin Lishen Battery Co., Ltd. is a main company with independent intellectual property. Rights Technical, a high-tech joint stock enterprise specializing in the technical research, development, production and operation of lithium-ion batteries and power batteries. The company is located in the ind zonefactory of Huayuan, Binhai High-Tech Zone, Tianjin, covering an area of 400,000 square meters. It was established on December 25, 1997, with registered capital of 1.25 billion RMB and total assets of 600 RMB. billion.
At present, the company has an annual production capacity of 500 million Ah of lithium-ion batteries, and its products include hundreds of models divided into four series: round, square , flexible polymer and plastic packaging, and power batteries. .
2. Recommendation: Sony VTC4 2100mAh or LG HD2 2000mAh
Both can provide high current, good capacity, good voltage and low voltage when working. , their performance is very close. HB6 and HB2 can easily discharge 30A, but they are rated lower due to their smaller capacity. They also operate at very low temperatures.
3. Recommendation: LG HB6 1500mAh
HB6 and HB2 have relatively low capacities. These are the only batteries that can be used for extremely high currents. and they are also available The battery with the lowest operating temperature. Although HB2 is also very good, HB6 has a lower temperature and slightly higher capacity. It is larger and has a slightly higher voltage, so it is the winner of the 30A and above group.
4. BYD
BYD was founded in 1995 and is listed on the Hong Kong Stock Exchange and the Shenzhen Stock Exchange, respectively. It is mainly active in the securities sector. secondary rechargeable battery production business, the IT industry mainly includes mobile phones, computer parts and assembly, and the automobile industry, including traditional fuel vehicles and energy vehiclesnew, and uses its own technological advantages to actively develop solar power plants and energy storage. power plants, LED and electric forklifts, including other new energy products.
5. BAK
BAK Battery Co., Ltd. was established in 2001 with a registered capital of 660 million yuan, equivalent to 82.6 million US dollars. It was listed on the NASDAQ in the United States on May 31, 2018 and is a listed company in the United States.
It is a high-tech enterprise integrating R&D, production and sales of lithium-ion batteries. The newly built BAK Industrial Park covers an area of 360,000 square meters and has more than 8,000 registered employees. The daily output of lithium batteries reaches 1.5 million units, making it one of the largest professional lithium battery manufacturers in the world.
Key points for purchasing:
18650 batteries generally have the advantages of large capacity, long life, high safety performance and wide range of use. When buying an 18650 battery, you usually need to understand its capacity, current, voltage, working temperature, etc., and then choose the 18650 battery you like.
Pacific Automotive Network's lithium iron phosphate material has better cycle performance and can still maintain more than 80% of its original capacity after 5,000 1C cycles . Type 18650 lithium battery is a lithium battery commonly used in electronic products and is often used as the battery core in laptop batteries.
Of course, lithium iron phosphate, but lithium iron phosphate is very expensive to produce with low capacity. Its advantages are stability, a forte consistency and a high number of 18650 cycles are generally seen in lithium batteries. while lithium iron phosphate batteries are more common and relatively rare. Lithium iron phosphate as a lithium battery material has only emerged in recent years. The domestic development of large-capacity lithium iron phosphate batteries took place in July 2005.
Its safety performance and service life are unmatched by other materials, and these are also the technical indicators the most important power batteries. The lifespan of 1C charge and discharge cycle reaches 2000 times. A single battery will not burn when overcharged to 30V and will not explode if punctured.
The lithium iron phosphate cathode material facilitates the series use of large-capacity lithium-ion batteries. To meet the needs of frequent charging and discharging of vehicleselectric ass. It has the advantages of non-toxic, pollution-free, good safety performance, wide source of raw materials, cheap price, long service life, etc. It is an ideal cathode material for the new generation of lithium-ion batteries.
This new material is not the previous lithium-ion battery cathode material LiCoO2 LiMn2O4; Its safety performance and service life are superior to those of other materials. Incomparable, they are also the most important technical indicators of power batteries. The lifespan of 1C charge and discharge cycle reaches 2000 times. A single battery will not burn or explode when overcharged to 30V. Puncture does not explode. Lithium iron phosphate cathode material facilitates the use of large capacity lithium ion batteries in parallel and series.
