These are all the best battery discoveries that could be with us soon, from over the air charging to super-fast 30-second re-charging
Monash University researchers have developed a lithium-sulphur battery that can power a smartphone for 5 days, outperforming lithium-ion. The researchers have fabricated this battery, have patents and the interest of manufacturers. The group has funding for further research in 2020, saying that continued research into cars and grid use will continue.
IBM Research is reporting that it has discovered a new battery chemistry that is free from heavy metals like nickel and cobalt and could potentially out-perform lithium-ion. IBM Research says that this chemistry has never been used in combination in a battery before and that the materials can be extracted from seawater.
uBeam uses ultrasound to transmit electricity. Power is turned into sound waves, inaudible to humans and animals, which are transmitted and then converted back to power upon reaching the device. The uBeam concept was stumbled upon by 25-year-old astrobiology graduate Meredith Perry. She started the company that will make it possible to charge gadgets over the air using a 5mm thick plate. These transmitters can be attached to walls, or made into decorative art, to beam power to smartphones and laptops. The gadgets just need a thin receiver in order to receive the charge.
