New high-performance lithium LiFePO4 cells

Lithium Iron Phosphate - LFP - LiFePO4-cell

After more than a year of intensive testing, we are now using a new high-performance lithium LiFePO4 cells to replace the cells used in our products.

This new generation of cell retains all the safety and robustness of those used in our products to date and adds two major improvements:

  • Specific Energy improved by 25% : It is possible to accommodate 1/4 more energy in the same volume.
  • Improved operation life by 50% : Cycling tests performed show a performance of 3000 cycles of full charge-discharge cycles (100% depth of discharge) at 1C. This represents a 50% increase in the number of cycles compared to the previous generation.
    At a DoD of 80% at 1C, the number of cycles performed rises to 4500.

Below chart shows the estimated number of cycles for our new generation of Lithium LiFePO4 cells, according to the discharge power and DOD figures. The test conditions are those of a laboratory (constant temperature of 25°C, constant charge and discharge power).

Life Cycle chart of new LiFePO4 cell generation

We can read from the chart the below figures :

  • 3 000 cycles at 100% DoD @ 1C
  • 4 500 cycles at 80% DoD @ 1C
  • 10 000 cycles at 60% DoD @ 1C
  • etc.

It should be noted that following the number of completed cycles, the cell still have a nominal capacity > 80% of the original capacity.

Our main product ranges: PowerBrick, PowerRack and PowerModule, will benefit in the coming months from this new generation of cells with an increase in capacity, a reduction in weight but also a significantly improved lifespan.

The E-mobility market today

Electro-mobility becomes more democratic

It is the ability or property for people or objects to move in a space, by a means of transport using partially or totally electrical energy.

Today, electromobility meets a major challenge in the fight against global warming. That of the replacement of polluting thermal engines by electric models more respectful of the environment.

According to figures released by the IEA (International Energy Agency), the number of electric cars in circulation around the world has sharply increased in 2016. With more than 750,000 units sold (40% more than the previous year), the market of green vehicles has exceeded the symbolic bar of 2 millions of units.


Some key figures:

  • China has become the main market for electrically powered cars. With more than 336,000 new registrations, it concentrates more than 40% of global sales in 2016. Moreover, there are 200 million electric two-wheelers and more than 300,000 electric busses.
  • In second place is Europe with more than 215,000 green cars in 2016.
  • In Norway, electric cars account for 1/3 of new car sales.
  • Next come the United Kingdom, France (where electromobility represents only 1.5% of the market share), Germany, Sweden and the Netherlands.
