DESTEN introduces 900 kW fast charger, EV

China-based DESTEN, an ultra-fast charging battery pack and solution provider, has developed an ultra-fast charging solution alongside a DESTEN-designed and -engineered electric car which can charge from 0% to 80% state of charge in 4 minutes and 40 seconds.

DESTEN introduced the technology in Jakarta, and plans to showcase these innovations in a global roadshow starting in Asia, then The Middle East, Europe, and North America.

DESTEN’s ultra-fast charging solutions enable drivers to charge an electric car as quickly as refueling a traditional combustion engine-powered car. DESTEN said its ultra-fast charging makes charging more accessible for EV drivers in urban and high-density areas, as well as reducing the total number of charging systems required to service EV charging demand.

DESTEN’s ultra-fast charging capability is the result of its discoveries in materials and cell structures, featuring novel chemical formulations produced on a custom manufacturing line. DESTEN says the cell can achieve 3,000 cycles and more than 1.5 million kilometers of total driving range.

Fast charging usually entails high levels of heat build-up within batteries. Despite ultra-fast charging speeds, DESTEN batteries retain high thermal stability, remaining cool throughout operation. The batteries are also certified by external testing organizations to maintain temperatures of less than 15 degrees Centigrade above ambient temperatures during operation.

Unlike other batteries, DESTEN battery cells do not require water cooling. This reduces costs and battery cooling systems’ weight, resulting in energy and cost savings.

DESTEN’s ultra-fast charging cells also allow for much-improved energy recuperation from driving. This creates the opportunity to design smaller battery packs for electric vehicles which cost less, making EVs more affordable.

With UN 38.3 certification, the battery has passed all safety tests, making it an ideal technology for automotive-grade battery solutions.

DESTEN’s battery cell technology is produced from primarily renewable energy sources, resulting in a smaller carbon footprint.

I was pleased to discover that Desten actually do provide some specs on their website, even though they ain't pretty:

160Wh/kg at the cell level is pretty limiting, and no real mention of costs or the need for buffer batteries to provide the charge, as is highlighted amongst other points in the article here:

So progress, of a sort, but with severe limitations.

When this first came out two years ago as part of the Piech Mark Zero it looked interesting. However, with more research it does not appear to be that special.
It is not the CATL Enerspeedy or GAC Aion battery since they only go to 5C.
10C is possible with Silicon anodes, though 3 years ago they were still at the lab level.
My guess is the chemistry is a Niobium Titanate (NTO) anode and NMC622 cathode. Toshiba had a NTO/NMC battery with 138 Wh/kg and 350Wh/l three years ago based on advanced SCiB tech. Other researchers added Molybdenum doping or Carbon coating to improve the battery. These batteries are capable of 10C charging and will last over 3000 cycles.
An NTO/NMC battery is not cheap and who needs 900 kW charging (this is no problem for the Piech Mark Zero GT since it costs $200k). The real question is who needs sub 5 minute charging, I.e. Extreme Fast Charging or XFC. Maybe Taxi or Package Delivery fleets. Even long range trucks could be charged overnight.
This battery has several problems: cost, energy density, and material issues.

The GAC Aion V can actually charge at 6C and almost 600A. On a 480kW charger, so 0-80% charge in 8 minutes. GAC uses a 3d Graphene based anode and the SUV costs less than $40k in China. Unfortunately, with CCS standard 350 kW is all we can expect.
