Silicon-dominant Li-ion technology also delivers additional automotive requirements including energy density, range, and cost

2 November 2017 - IRVINE, Calif.--(BUSINESS WIRE)

Enevate, a lithium-ion (Li-ion) battery technology company, announces HD-Energy® Technology for Electric Vehicles (EVs) which features extreme fast charging in only 5 minutes with high energy density and long driving range that adds up to 240 miles (390 km) or up to 50 miles (80 km) range with a 60-second charge. This fast charge and very short charging times are better than any other Li-ion technology available today, while meeting automotive requirements for energy density, range, and cost. Enevate licenses its silicon-dominant HD-Energy® Technology to battery and EV automotive manufacturers and suppliers worldwide.

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.

“The benefits of Enevate’s silicon-dominant HD-Energy Technology enable next-generation features that take EVs to the next level,” says Founder & Chief Technology Officer Dr. Benjamin Park. “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.”

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.

Lithium-ion battery pioneer Dr. John Goodenough at University of Texas in Austin agrees, saying “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.”

The facility’s location also leverages PSA’s parts supplier base and facility operations to support just-in-time inventory. This move towards digitised inventories reduces the need to hold excess inventory, which lowers storage costs, while shortening turnaround time from weeks to days due to improved availability of spare parts. In the long run, PSA will expand the scope of these services to the wider maritime industry, including ship owners, to help build its business adjacencies.
