Envia’s GM-backed battery delivers big power density, decrease prices, complications for rivals

Envia's GM-backed battery delivers huge energy density, lower costs, headaches for competitors

In the event you’re a type of fearful concerning the battery in your costly EV operating out, look away now. Envia has unveiled a brand new cell that boasts a document-breaking power density of 400Wh/kg (most presently supply between one hundred and one hundred fifty). It is estimated that when commercialized, this might convey the price of a 300-mile vary EV right down to as little as $20,000. The efficiency good points come from a particular manganese-wealthy cathode and silicon-carbon nano-composite anode mixture. The battery maker can also be partly owned by GM, which unsurprisingly means we’re more likely to see these very cells in its EVs sooner or later. Maybe with the correct selection of upholstery, we’d see even higher financial savings? Need to know extra? Faucet the absolutely charged press launch parked simply after the break.

Envia Methods Achieves World Document Power Density for Rechargeable Lithium-Ion Batteries

Breakthrough four hundred Watt-hour/kilogram Lithium-ion Battery Poised to Revolutionize Value, Vary and Security in Electrical Automobiles

NEWARK, Calif., Feb 27, 2012 (BUSINESS WIRE) — Envia Techniques, a know-how chief in excessive-efficiency, low-value lithium-ion power storage options immediately introduced check outcomes that confirm the corporate’s subsequent-era rechargeable battery has achieved the very best recorded power density of four hundred Watt-hours/kilogram (Wh/kg) for a chargeable lithium-ion cell. When commercialized, this four hundred Wh/kg battery is predicted to slash the worth of a 300-mile vary electrical car by chopping the price of the battery pack by greater than 50 %.

The testing of Envia’s subsequent-era lithium-ion battery was carried out by the Electrochemical Energy Techniques Division on the Naval Floor Warfare Middle (NSWC) in Crane, Ind., underneath the sponsorship of ARPA-E. Exams at numerous biking charges at NSWC confirmed that Envia’s automotive battery cell demonstrated power density between 378-418 Wh/kg for charges between C/three to C/10 for a forty five Amp-hour (C/three) cell. Comparable cells have been biking in Envia’s check labs for over 300 cycles. NSWC Crane may even check these cells to validate biking efficiency.

“Because the inception of Envia, our product staff has labored tirelessly and logged over 25 million check channel hours to optimally develop every of the lively elements of the battery: Envia’s proprietary Si-C anode, HCMR cathode and EHV electrolyte,” stated Dr. Sujeet Kumar, Envia Methods co-founder, president & CTO. “Slightly than only a proof-of-idea of power density, I’m happy that our staff was profitable in truly delivering four hundred Wh/kg automotive grade forty five Ah lithium-ion rechargeable cells.”

“Envia’s new battery know-how represents precisely the type of innovation and breakthroughs that ARPA-E is in search of from the American analysis and improvement group,” stated ARPA-E Director Arun Majumdar. “We hope that this low value and excessive density battery know-how allows broad unfold adoption of electrical automobiles throughout the nation and around the globe.”

“In an business the place power density tends to extend 5 % a yr, our achievement of greater than doubling state-of-artwork power density and decreasing value by half is a big step in the direction of realizing Envia’s mission of mass market affordability of a 300-mile electrical car,” stated Envia Methods Chairman and CEO Atul Kapadia.
