LFP batteries stands for Lithium iron phosphate(LiFePO4) batteries, which is known as li-phosphate batteries as well. They use phosphate as cathode material. In addition, they benefit from the low resistance properties that enhance their thermal stability and safety.
LFP batteries technology and applications:
LFP was invented in the year 1996. Its anode material is LiaC6, the cathode material is LibFePO4 and the carrier is Li+. They use LFP batteries in different applications like electric cars, electric buses and electric trucks. In addition, they use in electric motorcycles and scooters which need a longer life cycle and increased safety. LFP batteries offer many advantages over the NMC batteries traditionally used in Electric Two-wheelers.
LFP provides good electrochemical performance with lower resistance. This is enabled by the nano scale phosphate cathode material. The main benefits are long cycle life, higher current rating and thermal stability which means extra safety.
Why Should We Use LFP Batteries?
Durability and performance:
The efficiency of a LiFePO4 battery is very high and can range between 93 and 98%. Lithium iron phosphate battery storage systems can be charged and discharged around 5000 times.
Environmental compatibility:
Lithium iron phosphate batteries are one of the few cobalt-free lithium-ion batteries. They also do not contain other toxic heavy metals like lead and nickel which are commonly used in other batteries. Lithium iron phosphate, in contrast, is a substance that is in its chemical composition a naturally occurring mineral. Lithium iron phosphate-based batteries are considered to be safe, not toxic, and of low environmental impact.
Safe Battery Technology:
LFP battery storage systems have superior thermal and chemical stability than those based on cell technologies made with other cathode materials. They provide better safety characteristics, especially concerning potential fire hazards caused by improper overcharging or short circuit conditions.
LFP – Ideal Battery For Indian Conditions:
Given India’s tropical weather conditions, it is imperative for the battery pack to offer high temperature resistance.
LFP batteries are well suited for hot climates, because — unlike cobalt-based batteries—they are not hazardous at high temperatures. Not just the energy output but the chemistry and the safe operating temperature range are also very important.
From today’s perspective, lithium iron phosphate-based batteries are one of the safest battery technologies, low toxicity, well-defined performance, long-term stability, etc.
