Currently, many electric vehicles use the the lead acid battery for the 36V/10Ah mold, with 360 Wh total energy, 26.4 lbs. (12 kg) weight, and can be used to drive 30 miles (50km), under 100% optimal circumstances. Its cycle life is only about 100 - 300 times, each 12v battery price is about 35 - 40 USD, the service life is about 12 months. A big problem is the pollution produced by lead acid battery. If LiFePO4 material is adopted as anode to make 10Ah battery, it requires 12 battery pieces as series in a whole pack. The whole mold is only about 7 lbs. (3-4 kg) weight, if it can be made 11 lbs (5 kg) weight, the ebike can travel over 48 miles (80 km) far in laboratory experiments.
Comparing LiFePO4 battery with other EV Batteries
There are three types of lithium ion cells based on different cathode materials. They are lithium cobalt oxide, lithium manganese oxide and lithium iron phosphate types. Although lithium cobalt oxide cell has the advantage of high energy density, it suffers from safety concerns. Lithium manganese oxide cell has been evaluated for the application on high rate due to the better safety characteristics. However, its high temperature performance is the major drawback.
While Lithium iron phosphate cell has the best safety characteristics, long cycle life (up to 2000 cycles) and good availability. It is very suitable for high discharge rate occasions such as EV (including e-bike, electric scooter, and electric car), power tools, UPS and solar energy system. According to different applications, Liberty can modify the design of battery pack to provide the best solution to satisfy our customer' s needs.
REMARKS
1. Although, Lead Acid battery is lower in cost and safety acceptable; however, with extremely toxic, worse for the environmental concern, short cycle life, heavy in weight, therefore, we don't put it as a group for comparison.
2. Nickel Hydride battery has a characteristic of low Power Weight Density, decayed faster under the high temperature, worse in memory effect, not suitable for high output usage.
3. The C-coated Lithium Iron Phosphate Battery has been proven as the most environmental friendly battery. It is the safest and most suitable for high output usage. It is also the best for storage battery usage.
Your any sample order would be highly appreciated and OEM welcome.
Long life
Under normal operation, lifespan of LiFePO4 battery is more than 1000 recharging cycles, while more than 800 cycles for LiMn2O4.
High power
Light weight, small size, high capacity, high energy density
Safe and reliable
Materials and techniques provide dual assurances to Real Force battery safety. We use safe materials of LiFePO4 on the positive pole and aluminum foil as packing material for our high power battery.
After series of safety test on over βcharge, over-discharge, short circuit, dropping, heating, crushing and nail penetration, our battery has no explosion or combustion risk, which proves that the safety performance of RealForce LiFePO4 .
batteries completely meets and even exceeds the international standard.
Low self discharge rate
The battery is endurable with less than 3% self discharge rate every month.
No memory effect
Battery can be charged or discharged at anytime, and battery capacity wonβt fall off even under multiple incomplete discharges.
Consistency
We control the whole production process and strictly follow the standard of ISO9001 quality control system; therefore, our batteries perform consistently on internal resistance, discharge platform and voltage holding.
Humanized design
Our light weight batteries can be freely assembled and flexibly used. Customized battery size, shape and capacity are available in accordance with customersβ demands.
