Lithium iron phosphate battery

Source:

The lithium iron phosphate battery (LiFePO4 battery) or LFP battery (lithium ferrophosphate), is a type of rechargeable battery, specifically a lithium-ion battery, using LiFePO4 as the cathode material, and a graphitic carbon electrode with a metallic backing as the anode. The specific capacity of LiFePO4 is higher than that of the related lithium cobalt oxide (LiCoO2) chemistry, but its energy density is less due to its lower operating voltage. The main drawback of LiFePO4 is its low electrical conductivity. Therefore, all the LiFePO4 cathodes under consideration are actually LiFePO4/C.[3] Because of low cost, low toxicity, well-defined performance, long-term stability, etc. LiFePO4 is finding a number of roles in vehicle use, utility scale stationary applications, and backup power.

History

4is a natural mineral of thefamily (). Its use as a battery electrode was first described in published literature by Akshaya Padhi and coworkers of's research group at thein 1996,as a cathode material for rechargeable lithium batteries. Because of its low cost, non-toxicity, the natural abundance of, its excellent thermal stability, safety characteristics, electrochemical performance, and specific capacity (170/, or 610https://en.wikipedia.org/wiki/Lithium_iron_phosphate_battery

Boil water with Lithium Iron (LiFePO4) cell

Single Lithium Iron Phosphate (LiFePO4) cell used to boil a cup of coffee, simple demonstration of the power these cells provide. Unlikely majority of common battery technologies, fast discharge up to 10C (10 times the capacity) doesn’t have negative impact on the lifetime and number of cycles.

About the ZG cell in video: thin metal housing of the cell contribute to high energy density and is ideal for projects with limited free space. Frequently used in all sorts of moving machines (forklift etc.) or compact Energy Storage systems (ESS).

How to recycle the industrial large capacity LFP cells?

Blog EVPower

The large capacity LFP cells should be recycledin the same way as all other lithium or li-ion cells.

There is no change or difference because of the size of the cells. As with any other cells, you should recycle only cells that were fully discharged and have 0V potential on the terminals.

Follow these steps:

1) Discharge the cell completely to0V.
2) Short-circuit the terminals of the cell - connect the PLUS and MINUS poles of the cell with a conductive wire
3) Dispose of the cells at your recycling center or facility.
4) In some rare cases the recycling company may request some technical datasheets to verify the chemical composition of a cell. In this case please contact GWL and we will be happy to assist you.

Let us make the best use of the LFP technology and if need to be disposed of, let us make the better world by recycling in the most responsible way.

Micro Energy Storage Setup – 2019 update

Blog EVPower

Micro Energy Storage Setup

NOTE: this is a grid-tied system setup with an energy back up to the batteries. This system is grid-tied only. The micro-inverter works only when the grid is present. If the grid is down, the system does not work. It is NOT an off-grid system.

NOTE (2019 update): the illustrational picture shows a system we made in 2013 with some components which are no longer available (like the 36V regulator). We've nevertheless updated the list of components below so you can make the same system with components which are up to date and available in our e-shop.

* * * * *

A practical realization of a small size energy storage solution with 3.2 kWh of energy capacity with 230V/230W AC grid-tied power output. The basic concept of energy storage with easy expansion. The purpose of the installation is to store the energy in the batteries and release the energy slowly when needed.

Winston cells passed the China Army military safety tests

Blog EVPower

The photo shows the punch-through simulating a shooting from 45 mm calibre anti-tank gun.

Fully charged cells are punched through simulating the shoot-through from a military weapon. The purpose of the test is to see the safety and stability of the lithium cells.

As visible from the photo, the cells remained complete, did not burn, did not set on fire and did not explode. This kind of extreme abuse proved that superiority of the Winston Battery lithium cells. These cells are suitable for all kinds of applications including the heavy duty and military grade installations.
