Lithium Iron phosphate battery

Lithium Iron Phosphate Battery

Lithium Iron Phosphate Battery (LiFePO4) also short form (LFP)

A lithium Ion rechargeable battery Use LiFePO4 as a anode material A relatively new and revolutionary battery for Industrial and consumer electronics

LFP vs Other kinds of Lithium battery

Three types:  Lithium Cobalt Oxide (LiCoO2) (LCO) (Use in most consumer electronic devices, mobile phone, tablets, notebook)  Lithium Manganese Oxide (LiMn2O4) (LMO) 

Lithium Iron Phosphate (LiFePO4) (LFP)

LFP vs Other kinds of Lithium battery

LCO LMO * Higher energy density * Safety concerns, relatively easy to catch fire, explode (recent 787 planes battery issue) * Safer * High temperature performance very bad, decade extremely fast at 50C * More expensive

LFP vs Other kinds of Lithium battery

LFP *

Best Safety Characteristics

(not required BMS, battery management system and protection module) * Long cycle life (>2000 times) * Good availability on material * Higher discharge current * Lower energy density ( increase energy density overcome by our proprietary Nano Technology to )

Major Advantages and Characteristics of LFP

Safest and the Most Environmental friendly (overcharge and overheat can cause fire and explosion for other Lithium battery but not LFP) Fast “forced” Charging (because an overvoltage can be applied) Large overcharge tolerance and Safer Performance (can overcharge 30V w/o protection circuit, i.e. best for high power and large capacity application) Higher energy density (specific capacity> 145Ah/kg, gravimetric energy density is 130Wh/kg)

Major Advantages and Characteristics of LFP

Simplified Battery Management system and Battery Charger (because large overcharge tolerance and self-balance characteristics, i.e. low cost) Longer Cycle life (LiCoO2 is around 300, LFP can be > 2000) High Temperature Performance > 70C, remain stable even at 160C High current discharging (e.g. standard 2-5C, continuous high current discharge can be 10C, temporary high current discharge can be 20C (10s)) No Memory effect
