In our fight against climate change, Electric vehicles can play a very important role. Electric Vehicles could help in reducing greenhouse gas emissions, air pollution, and vehicular noise pollution.
But charging time is an important concern when one plans to buy these environmentally-friendly electric vehicles.
Now, California-based startup Enovix Corporation has come up with a solution. This startup has unveiled its next-generation 3D Silicon™ Lithium-ion batteries. The company demonstrated the ability of its 0.27 Ah Electric Vehicle (EV) test cells. Its battery can be charged from 0% to 80% in only 5.2 minutes, and over 98% in less than 10.
“Fast charge capability can accelerate mass adoption of EVs and we’ve been able to demonstrate a level of performance that meets and exceeds many OEM roadmaps,” said Harrold Rust, Co-Founder, CEO, and President of Enovix.
“EV manufacturers are in pursuit of batteries that support longer range, while the public and private sectors work to increase EV driver access to fast chargers. We’re proud to support these goals to help electrify the automotive industry and demonstrate our batteries are an exciting option to power long-range, fast-charging EVs.”
The battery cells are built with silicon anodes having a capacity of 1,800 milliamp-hours (mAh) per cubic centimeter (cc). This gives it a much higher energy density. For comparison, conventional lithium-ion cells which are built with graphite anode have a capacity of 800mAh/cc.
Startup showed in its tests that even after six months at elevated temperatures, their batteries had a minimal capacity loss. This pairing also projects a lifetime of over 10 years for Enovix batteries.
