Improved safety of the 12V 100AH LiFePO4 battery
The P-O bond in the lithium iron phosphate crystals is strong and difficult to decompose, even at high temperatures or when overcharged, the structure does not collapse and heat up or form strong oxidising substances like lithium cobaltate, so it has a good safety profile. It has been reported that a small number of samples were found to burn during pin prick or short circuit tests in practice, but there was no case of explosion, while overcharging tests using a high voltage charge that was several times higher than its own discharge voltage still revealed an explosion. Nevertheless, the overcharge safety has been greatly improved compared to that of ordinary LiCoO2 batteries with liquid electrolyte.
Improvements in the life of the 12V 100AH LiFePO4 battery
The 12V 100AH LiFePO4 battery is a lithium-ion battery using lithium iron phosphate as the cathode material.
Long-life lead-acid batteries have a cycle life of around 300 times, up to 500 times, while lithium iron phosphate power batteries, cycle life of more than 2000 times, the standard charge (5 hours rate) use, can reach 2000 times. The same quality of lead-acid batteries is “new half year, old half year, maintenance maintenance and half year”, at most 1 ~ 1.5 years, while 12V 100AH LiFePO4 battery in the same conditions of use, the theoretical life will reach 7 ~ 8 years. Considered together, the performance to price ratio is theoretically more than 4 times that of lead-acid batteries. The high current discharge can be charged and discharged quickly with a high current of 2C. Under a special charger, the battery can be fully charged within 40 minutes at 1.5C and the starting current can reach 2C, whereas lead-acid batteries do not have this performance.
12V 100AH LiFePO4 battery high temperature performance
Lithium iron phosphate electric heat peak up to 350 ℃ -500 ℃, while lithium manganese acid and lithium cobalt acid only in about 200 ℃. Wide operating temperature range (-20C – 75C), with high temperature resistance lithium iron phosphate peak electrical heating up to 350 ℃ – 500 ℃, while lithium manganate and lithium cobalt only in the 200 ℃ or so.
12V 100AH LiFePO4 battery large capacity
Battery in often in the full not put out of the conditions of work, the capacity will quickly lower than the rated capacity value, this phenomenon is called the memory effect. Like NiMH and NiCd batteries have memory, but 12V 100AH LiFePO4 battery does not have this phenomenon, the battery can be charged and used no matter what state it is in, without having to be discharged and then recharged.
12V 100AH LiFePO4 battery is light in weight
A 12V 100AH LiFePO4 battery of the same capacity is 2/3 the size and 1/3 the weight of a lead-acid battery.
12V 100AH LiFePO4 battery is environmentally friendly
The 12V 100AH LiFePO4 battery is generally considered to be free of any heavy and rare metals (NiMH batteries require rare metals), non-toxic (SGS certified), non-polluting and compliant with European RoHS regulations, making it an absolutely green battery certificate. So lithium batteries are favored by the industry, mainly because of environmental considerations, so the battery is included in the “863” national high-tech development plan during the “Tenth Five-Year Plan”, becoming a key national support and encourage the development of the project. With China’s accession to the WTO, the export volume of Chinese electric bicycles will increase rapidly, and the electric bicycles entering Europe and America are already required to be equipped with non-polluting batteries.
