One of the main roadblocks to wide adoption of EVs is how quickly the battery can be fully charged. While Tesla’s Supercharger could put a Model S P85D back on the road in 30 minutes to an hour, a Dodge Charger Hellcat can pull up to and away from the pump in three minutes, barring a run inside the 7-Eleven for a cup of coffee and a couple of donuts.
That roadblock may come down sooner than later, thanks to researchers at Singapore’s Nanyang Technology University.
The university recently unveiled a new battery that could be recharged to 70 percent capacity within two minutes, and boasting a lifespan of 20 years over the two to three years of life found in current lithium-ion batteries.
The secret? Replacing the graphite anode in those batteries with a nanogel composed of titanium oxide, a chemical commonly found in soil, sunscreen and food. Invented by Professor Chen Xiaodong at the university’s School of Materials Science and Engineering, the gel will be taken to the next level with a proof-of-concept grant to help fund a large-scale prototype.
Meanwhile, at least one company has already purchased a license to develop the titanium oxide battery for production down the road. Chen himself believes his invention will enter the marketplace within the next two years, knocking down more than just the long-charging barrier in so doing:
Electric cars will be able to increase their range dramatically, with just five minutes of charging, which is on par with the time needed to pump petrol for current cars.
Equally important, we can now drastically cut down the toxic waste generated by disposed batteries, since our batteries last ten times longer than the current generation of lithium-ion batteries.
Ease of manufacturing and lower replacement costs may further widespread adoption within the industry, in turn increasing adoption rates for whatever EVs come down the line in the future; the nanogel — a mixture of titanium oxide and sodium hydroxide — is stirred together at a given temperature for easier integration into current production systems.
