Enevate HD-Energy Technology

Enevate HD-Energy Technology

Enevate Corporation, which we first spotted on the battery start-up radar two years ago (here and here), has announced a breakthrough in battery cells for electric vehicles.  (and yes, we are aware how often we have reported such claims.)

According to the Enevate, its new HD-Energy Technology NCM-based cells with silicon-dominant anode are capable of fast charging in just minutes, while meeting automotive requirements for energy density, range, and cost.

The company said that in just 5-minutes a long-range BEV could replenish up to 240 miles (390 km) of range, or or up to 50 miles (80 km) of range with a 60-second charge.

The HD-Energy Technology cells accept up to 10C charging - up to a 75% state-of-charge.

Volumetric energy density is said to be over 750 Wh/L, and those batteries can be charged down to -40°C.

Well, if the prices also are indeed competitive (and longevity/stability of the cells isn't an issue), we hope that market introduction is just around the corner.

"This new extreme fast charge technology breaks down the barriers to electric vehicle adoption. EVs have been challenged primarily due to their limited range and drivers’ “range anxiety,” long charge times, and high cost. Now, Enevate’s groundbreaking silicon Li-ion battery technology in EV cells (NCM-based) can be charged in 5 minutes at up to a tested 10C charging rate to 75% capacity with uncompromised range and energy densities of over 750 Wh/L, where conventional graphite cells suffer significant degradation with extreme fast charging.

This 5-minute charging allows flow-through charging stations where EV drivers wait just a few minutes to “fill up” just as they would with regular gas stations. In addition, with such short charging times, smaller batteries can be used in some EVs making them much more affordable."

"Enevate’s HD-Energy battery technology can safely charge and discharge down to -40°C and capture more energy during regenerative braking, extending their range in cold climates. A key safety benefit is that Enevate’s HD-Energy Technology is inherently resistant to lithium-plating during fast charge and also during charging in low temperatures, which is a major challenge for conventional graphite Li-ion cells."

Founder & Chief Technology Officer Dr. Benjamin Park said:

“The benefits of Enevate’s silicon-dominant HD-Energy Technology enable next-generation features that take EVs to the next level. Extreme fast charges for very short and convenient charging times, higher energy density leading to longer driving ranges, and cold temperature operation with inherent safety advantages make this technology ideal for electric vehicles.”

Lithium-ion battery pioneer Dr. John Goodenough at University of Texas in Austin said few years ago:

“Enevate’s film-based silicon-dominant anode and cell is a truly novel approach and great practical fit for use in EVs addressing the major barriers to EV adoption.”

Enevate's silicon-dominant EV battery technology features up to 10C charging rates with over 750 Wh/L energy density.
