New Li-ion batteries get a quick charge
Recently, researchers from University of technology Nanyang (NTU), Singapore, has developed a new battery that can be recharged to 70 percent capacity in just 2 minutes. The new battery also has longer lifespan – over 20 years. According to the researchers, the new lithium-ion battery new generation is almost 20 times less time to charge than conventional batteries in electric vehicles.
According to estimates, the driver of an electric car only takes about five minutes to charge the battery is comparable to the waiting time filling the gas tank of a conventional car at a gas station. Moreover, the new battery can withstand more than 10,000 charging cycles – 20 times more than available on the market today batteries.
Scientists replaced the traditional graphite that is typically used for the anode (negative electrode) in lithium-ion batteries with a new gel material made from titanium dioxide, a common, cheap and safe material. This material is now widely used as a food additive and also in the sunscreen lotions to absorb harmful ultraviolet rays.
In order to convert the spherical particles of titanium dioxide into tiny nanotubes, with a thickness of 1000 times smaller than a human hair, scientists have developed a simple method. These nanotubes accelerate chemical reactions and, consequently, provide ultra-fast charging battery.
The researchers have patented their technology and now they are planning to build a full-scale prototype of the battery. As expected, the new generation of quick loading of batteries will hit the market within two years. However, this technology has already attracted interest from industrial companies.
An equally important advantage of the new batteries scientists believe the opportunity to significantly reduce the amount of waste associated with the processing and recycling of old batteries. And thanks to the longer service life of the battery, drivers can save on the cost of replacement, which can reach more than 5000 US dollars. published
