What is LiFePO4 Battery and why it’s better than other lithium batteries?

What is the LiFePO4 Battery?

The LiFePO4 battery is a type of lithium-ion rechargeable battery. LiFePO4 stands for Lithium (Li) Iron (Fe) Phosphate (PO4). LiFePo4 Battery knows by many Names Like lithium iron phosphate battery or LFP battery. LFP batteries use lithium iron phosphate (LiFePO4) as the cathode material alongside a graphite carbon electrode with a metallic backing as the anode.

Lithium iron phosphate batteries can be used in high-temperature environments, where lithium-ion cells should never be used above +60 Celsius. Lithium iron phosphate cells have greater cell density than lead acid, at a fraction of the weight.

Types of Lithium Batteries

Lithium Cobalt Oxide (LiCoO22) Battery
Lithium Nickel Manganese Cobalt Oxide (LiNiMnCoO2) Battery
Lithium Titanate (LTO) Battery
Lithium Manganese Oxide (LiMn2O4) Battery
Lithium Nickel Cobalt Aluminum Oxide (LiNiCoAlO2) Battery

Advantage Of LiFePO4 Battery

Lithium iron phosphate batteries (LiFePO4 or LFP) offer lots of benefits compared to lead-acid batteries and other lithium batteries. Longer life span, no maintenance, extremely safe, lightweight, improved discharge and charge efficiency.

One important advantage Of the LFP batteries over other lithium-ion batteries chemistries is thermal and chemical stability, which improves battery safety. Lithium iron phosphate cells have less cell density than lithium-ion. This makes them less volatile, and safer to use. LiFePO4 batteries are the safest and most stable lithium battery chemistry. Unlike other lithium batteries, lithium iron phosphate battery does not catch fire or explode.

LiFePO4 is an intrinsically safer cathode material than LiCoO2 and manganese dioxide spinels through the omission of the cobalt, with its negative temperature coefficient of resistance that can encourage thermal runaway.

Is LiFePO4 better than lithium-ion?

The lithium iron phosphate battery has advantages over lithium-ion, both in terms of cycle life (it lasts 4-5x longer), and safety. This is a key advantage because lithium-ion batteries can overheat and even catch fire, while LiFePO4 does not.

What is the difference between NMC and LFP Batteries?

LFP batteries deliver at least 2500 – 3000 full charge/discharge cycles before reaching 80% of the original capacity. Typical NMC batteries deliver 500 – 1000 full charge/discharge cycles before reaching 80% of the original capacity. This means that LFP batteries provide FOUR times more cycle life than typical LCO batteries.

New tests prove that LFP Lithium Batteries have a Longer Life span than NMC.

Testing conducted by various testing labs, during the study and testing of LiFePO4 Batteries, some interesting facts come out. LFP chemistry is superior compared to NMC – it is safer, offers a longer lifespan, and is generally less expensive than NMC, and NCA.

Low Cost and Low Impact on the Environment

lithium iron phosphate battery is known for its low cost with some estimates putting it as much as 70 percent lower per kilogram than nickel-rich NMC. The cost advantage comes from its chemical composition. Iron and phosphorus are mined at enormous scales across the globe and are widely used in many industries.

LiFePO4 Batteries Usage

Lithium iron phosphate batteries are widely used in passenger cars, buses, logistics vehicles, low-speed electric vehicles, Solar Power Storage, etc. due to their safety and low-cost advantages.

The energy density of LFP batteries is lower than the alternative of lithium cobalt oxide (LiCoO2) and has a lower operating voltage. In spite of these challenges, it’s impossible to deny the benefits of LFP batteries in EV vehicles.

Higher discharge rates needed for acceleration, lower weight, and longer life make this battery type ideal for forklifts, bicycles, and electric cars. 12V LiFePO4 batteries are also gaining popularity as a second (house) battery for a caravan, motor home, or boat.

Tesla Motors currently uses LFP batteries in certain vehicles.

Gas Turbine Types: Overview of Types and Profitable Applications

The four major types of gas turbine engines are discussed here. In the aviation sector, the most common propulsion technology is the aircraft turbine engine. There are different varieties of turbine engines, each with its own unique set of maintenance and overhaul requirements. As a result, choosing the correct business to do repairs and maintenance on your aircraft turbine engine is critical. Keep in mind that such a wide range of gas turbine designs can only be found in aircraft gas turbines. The configuration of gas turbines used in power plants is similar to that of turbojet engines, which will be addressed later.

Turbojet Engines

Turbojet engines were the first form of the gas turbines. Even though they don’t seem like reciprocating engines, they work on the same principle: intake, compression, power, and exhaust. Air is pushed at a rapid rate to the fuel inlet and ignitor of the combustion chamber in this type of engine. By expanding air, the turbine causes faster exhaust gases.

Turboprop Engines

A turboprop engine is the second type of gas turbine. It is a turbojet engine with a propeller coupled via a gear system. The operation of a gas turbine of this sort is as follows:

  • A shaft connected to a transmission gearbox spins while the turbojet spins.
  • A transmission box slows the spinning process, and the transmission mechanism is coupled to the slowest moving gear.
  • The air propeller spins, creating thrust.

Turbofan Engines

Turbofan engines are combined with the world’s top turbojets and turboprops. A duct fan can link a turbofan engine to the front of a turbojet engine. The fan then provides an extra push, which aids in cooling and decreases engine noise.

Turboshaft Engines

Turboshaft engines, the fourth gas turbine type, are mostly employed in helicopters. The most significant distinction is that turboshaft engines use the majority of their power to spin turbines rather than propel them out the back. A turbojet engine with a big shaft attached to the back is known as a turboshaft engine.

Components of a Gas Turbine Engine

Propulsive thrust can be generated using a gas turbine engine. In the case of a pure jet engine, this can power a generator, pump, or propeller while also creating thrust through the nozzle. While the gas turbine engine is a basic system, due to the high operating temperatures and strains, components for a powerful machine must be carefully constructed and produced from expensive materials. As a result, gas turbine engines are often limited to big units where they are cost-effective. A compressor (takes in and compresses the air), combustor (applies fuel to the air and ignites it), turbine (converts high-speed gas energy into rotary power through expansion), gearbox and shaft (provides rotary power to the driven devices), and exhaust nozzle are the main components of a gas turbine (runs out of the turbine part the low emissions of spent gas).

Gas turbine gearboxes are widely used in today’s gas turbine designs. Based on the turbine’s rotational speed and power output, this component is responsible for effectively delivering the turbine’s produced power to the moving parts. However, recent versions use direct drive, which means there is no gearbox inside the gas turbine engine and the turbine rotational power is sent directly to where it is needed.

Gas turbine control system

The gas turbine control system monitors and safeguards the gas turbines. With integrated control system solutions, you may get superior performance for a connected plant. It scales and adapts to changing requirements in thermal and renewable power generation, oil and gas, and safety applications with ease. IS200VCMIH1B and IS200VCRCH1B are some examples of GE control system parts.
