Desten presents fast charging LFP batteries

Battery technology company Desten has just presented a fast-charging LFP battery. According to the company, the 22 Ah pouch cell can be charged from 20 percent to 80 percent SoC in six minutes. The 22 Ah pouch cell should also be suitable for electric cars.

The new LFP cell from Desten boasts a capacity of 22 Ah and a fast-charging capability of 6C. The new LFP cell is also said to have an energy density of 160 Wh/kg, reaching 80 per cent of its original capacity after more than 5,000 charging cycles. According to the developer, this is possible because the cell only heats up by 15 degrees when charging at 6C. This should also make this cell very safe. The 6C is not only possible when charging, but also when discharging. A complete charging process (theoretically) takes ten minutes, and the window from 20 to 80 per cent takes six minutes.

Desten Group began in Hong Kong and became known for fast-charging cells. The group incorporated a US company based in California. Desten has some very fast-charging NMC pouch cells that can be charged at up to 10C – the window from 20 to 80 per cent, which only takes 3 minutes and 40 seconds. For this new LFP cell, Desten only states a continuous discharge rate of 2C for the NMC cell with 10C (and a capacity of 19 Ah).

Desten says it is now working with its partners in North America, Europe and Asia to integrate its new LFP cells into platforms for electric vehicles and stationary energy storage systems. The company has already made the first samples available to OEM partners.

“LFP is becoming a leading chemistry for mass market applications,” remarked Thomas Gerhard Wilhelm Damitz, Chief Innovation Officer of DESTEN Inc. “By developing a combination of fast charging, safety, longevity and cost efficiency, the future of our grids and mediums of transportation are secured.”

LFP technology knowledge is largely located in China. Electric vehicle giant BYD, in particular, has specialised in the technology with its blade batteries first presented in March 2020. Last month, Daimler Truck, Paccar and Cummins announced they aim to build LFP batteries in the USA. Also starting up LFP battery production in the USA is Our Next Energy (ONE), supported by BMW among others, and is now developing the second generation of its Aries battery pack with LFP chemistry.

In Europe, Mercedes will be using LFP batteries from BYD. BYD uses the blade batteries in its own models, but also markets them to third parties. For example, the Chinese manufacturer supplies Tesla’s Berlin plant with blade batteries. The Toyota bz3 and the Kia EV5 will also feature blade batteries from BYD.
