Scientists build a battery that charges 70 percent in two minutes and lasts for 20 years
Get ready: In the near future, you may be able to charge your dead smartphone to mostly full during a single commercial break; your Tesla's range will go from zero to hundreds of miles in the parking lot while you make a quick grocery run; and — best of all — your devices won't need replacement batteries for two decades.
Scientists at Nanyang Technological University in Singapore hacked the lithium-ion battery's charging mechanism, replacing the traditional lithium-ion's graphite anode with a gel made from titanium oxide, a food and sunscreen additive found in abundance in soil. A new technique transformed the gel's titanium dioxide particles from spherically-shaped to ultra-thin nanotubes, speeding up the chemical reactions that charge the battery while increasing its longevity to 10,000 charging cycles — 20 times the typical 500 cycles of current battery technology.
