IRVINE, Calif.--(BUSINESS WIRE)--Enevate, a pioneer in advanced silicon-dominant lithium-ion (Li-ion) battery technology capable of extreme fast charging for electric vehicles (EVs), announced its new 4th generation technology optimized for high volume commercialization and manufacturing at gigafactory scale. Enevate is providing a solution to a difficult problem for automotive OEMs and EV battery manufacturers – providing extreme fast charging with high energy density and at lower material cost than conventional Li-ion batteries, while being compatible with existing battery fabrication facilities.
The new XFC-Energy™ technology achieves 5-minute charging to 75 percent capacity with 800 Wh/L cell energy density. Today’s conventional large-format Li-ion EV cells are at 500-600 Wh/L and typically take over 1 hour to charge.
“Mass EV adoption by consumers and fleet owners will depend to a large degree on advanced battery technology that will remove current barriers to entry such as long charging times and limited range,” said Christian Noske, Chairman of Alliance Ventures (Renault-Nissan-Mitsubishi). “Enevate is a key enabler for electric vehicles that are affordable, easy and quick to charge, and clean.”
Dr. John Goodenough, a recipient of the 2019 Nobel Prize in chemistry for groundbreaking work in the development of lithium-ion batteries and who has served on Enevate’s Advisory Board since 2010, added: “I salute the Enevate team for reaching this next important step in fulfilling the company’s mission to develop and commercialize innovative battery technologies to accelerate the adoption of electrified mobility.”
Enevate’s 4th generation XFC-Energy technology stands to be a game-changer for the EV industry, providing a path to produce extreme fast-charge EV batteries at low cost and high-volume production. Enevate is currently working with multiple automotive OEMs and EV battery manufacturers to commercialize its technology for 2024-2025 model year EVs, utilizing existing manufacturing infrastructure with minimal investment required, a core goal of its development.
Enevate’s 4th generation is the latest result of over 74 million hours of battery cell testing by Enevate’s scientists, 1 million meters of electrodes produced in the company’s R&D pilot line, and 2 billion test datapoints.
Enevate Founder and Chief Technology Officer Dr. Benjamin Park noted that Enevate’s XFC-Energy technology has been designed for large-format pouch, prismatic and cylindrical EV cells, utilizing its pure silicon anode paired with nickel-rich NCA, NCM and NCMA advanced cathodes.
“Enevate’s extreme fast charge technology enables a future where gas stations become drive-through EV charging stations – a win-win for consumers and the environment as electric vehicles replace those using gasoline,” Dr. Park said. “Enevate’s technology will help close the usability gap between today’s EVs and gas cars.”
Dr. Park will be discussing Enevate’s technology on January 15 at the Advanced Automotive Battery Conference in Weisbaden, Germany, in a presentation titled “Charging Ahead: Commercializing Fast-Charge Si-Dominant Li-ion Cells for EVs.”
