MIT’s team headed by Gerbrand Ceder has developed aninnovative technique that could immensely reduce the Lithium-ion battery charging times from hours to mere seconds. Their Eureka movement comes with the coating of lithium phosphate that is applied to an existing battery. The coating works in a way which attracts ions faster to the tunnels leading to the battery terminal and charging faster. A normal mobile phone could get charged in just 10 seconds whereas a big electric car could go full in just a few minutes.
However, one problem I see here is faster the battery recharge; faster the discharge will be too. Now I wouldn’t want to carry my phone’s charger everywhere because it will potentially reduce the battery talk time even though it can back up again in few seconds.
The technology nonetheless looks promising and the implementation in the real world will be the key which will probably take more 2-3 years.
