New battery tech promises a longer life, 70-percent charge in 2 minutes
Researchers in Singapore have developed a new battery that charges up to 70-percent in two minutes, and will retain its ability to hold a charge 10 times longer than current batteries. The new lithium ion battery could vastly improve both mobile devices and electrical cars, and it will be on the market in two years, according to Science Alert.
The new lithium ion battery was designed by researchers at Nanyang Technological University in Singapore. Along with allowing for rapid charging, the new battery will last ten times longer than current batteries. A standard battery is limited to around 500 charging cycles before it wears out, giving it a lifespan of around three years, give or take. The new battery will allow for 10,000 charge cycles, increasing its life to around 20 years.
The speed at which it charges and the lifespan will not only improve mobile devices, it could potentially change electrical cars.
“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,” Professor Chen Xiaodong, the leader of the research team said in a statement. “Equally important, we can now drastically cut down the toxic waste generated by disposed batteries, since our batteries last 10 times longer than the current generation of lithium-ion batteries.”
Electrical car manufacturers are constantly working on their own ways to improve battery life though, so the industry may decide to head in a different direction. Still, the potential is there.
The advancement comes thanks to the development of a new material created from common materials. Traditional batteries use graphite in the anode – the negative pole of a battery. The new battery uses a gel-material created from titanium dioxide nanotubes, which the team designed.
Those nonotubes are one thousand times thinner than a human hair, and they allow electrons and ions to transfer faster than ever before, which also forces more energy into the battery. That leads to faster charging and a longer life.
And if that wasn’t enough, titanium dioxide is inexpensive and readily available, and commonly found in the soil. That means the new batteries will be comparatively cheap, and they will only get cheaper.
Expect to see these batteries hitting commercial devices in the near future.
