Brightrix’s core products are based on two battery types — Terpolymer Lithium Battery and LiFePO4 Battery.
Terpolymer Lithium Battery
This new polymer electrolytes composed of acrylonitrile‐methyl methacrylate‐styrene (AMS) terpolymer, 1 M Formula ‐EC/PC, and an inorganic filler have been prepared. Depending on the composition of the components, these electrolytes exhibit a wide range of mechanical and electrical properties. The ionic conductivity reaches Formula in a polymer electrolyte containing 27% AMS terpolymer, 64% Formula ‐EC/PC, and 9% silanized fumed silica at room temperature to give homogeneous films which exhibit good mechanical properties. These systems showed good compatibility with lithium electrodes and a sufficient electrochemical stability to allow safe operation in the rechargeable lithium batteries. The capacity and cycling performance of a Li/polymer electrolyte/Formula solid‐based polymer electrolyte were investigated.
LiFePO4 battery is a new generation of Li-ion battery that uses LiFePO4 as cathod material instead of LiCo2O4. The excellent safety (100% non-explosive) and good cyclic performance etc. LiFePO4 Cells is regarded as”the coming of new era of Li-ion batteries”, and especially becomes the top choice of cathod materials for power battery.
LiFePo4 Cells Features:
- Excellent safety
- Good performance of anti-overcharge
- Good discharge Capability
- Great cyclic performance
- Good Storage
- LiFePO4 Cells could be used in the consumer mobile electronics market, especially has the trends to be applied in Hybrid Electric Vehicles, Electric Bikes and Scooters etc

|NiCd||1.2V||> 40wh/kg||-20 – 50 °C||>1000||Safe||Bad||0.7|
|NiMH||1.2V||>80 wh/kg||-20 – 50 °C||>500||Safe||Good||1.2-1.4|
|LiMnxNiyCozO2||3.7V||>160 wh/kg||-20 – 40 °C||>500||better than LiCo||OK||1.5-2.0|
|LiCoO2||3.7V||>200 wh/kg||-20 – 60 °C||> 500||Unsafe w/o PCM||OK||1.5-2.0|
Brightrix has successfully developed lifepo4 battery technology widely on Electric vehicle application. Batteries can offer high peak power even near the end depth of discharge, almost the same as fully charged state
Brightrix lithium iron phosphate battery is widely used on Electric car, such as battery electrical vehicle (BEV), plug-in hybrid electrical vehicle (PHEV) and hybrid electric vehicle (HEV).
Light traction vehicles, like electric scooters, motorcycles, and some other similar light vehicles, are the huge market for LiFePO4 battery application, definitely would flourish in the following years.
Brightrix has developed the LifePO4 battery which is applied for energy storage area. The producing technology is optimized for cost lowing down, nearly same to most AGM batteries. The application ranges from small portable personal energy storage to medium size family energy storage to buffer the green energy generated by wind turbine or solar panel, to large enterprise or utility level energy storage.
Brightrix has developed the LifePO4 battery which is applied for marine storage area.
For industrial application, here are lots of battery powered motive and tools, for carrying cargo, lifting, handling and other usage. They formerly using lead acid and recent years using some of Ni-Cd batteries, now there time for LifePO4 batteries.
LFP cells are now used in some solar powered path lights instead of NiCd. Their higher working voltage allows a single cell to drive an LED without needing a step-up circuit. And the high tolerance to modest overcharging (compared to other batteries) means that the batteries can be connected to photovoltaic cells without complex circuitry. Some models claim to be 24x brighter than baseline path lights.
RC model cars may use these batteries, especially as RX and TX packs as a direct replacement of NiMh packs or LiPo packs without need for voltage regulator, as they provide 6.6v nominal voltage over 7.4v of LiPo packs, which is little higher and may require to be regulated down to 6.0v.
