Charged up

Down to Earth - - THE FORTNIGHT -

Are you frus­trated by the slow charg­ing of your phone's bat­tery or feel the need to re­place it very of­ten? Here is some good news to cheer you up. Lat­est re­search and ad­vances in lithium-ion bat­tery tech­nol­ogy now makes it pos­si­ble to charge the bat­tery in a few min­utes. What's more, the bat­tery is ex­pected to last for 20 years. Sci­en­tists at the Nanyang Tech­nol­ogy Univer­sity, Sin­ga­pore, have de­vel­oped ul­tra­fast charg­ing bat­ter­ies that can be recharged up to 70 per cent in only two min­utes and can last more than 10 times com­pared to ex­ist­ing lithium-ion bat­ter­ies.
