Charging still needed for mobile phones, tablets, and electric vehicles
Nanyang Technology University (NTU) Scientists have developed lithium ion batteries that are capable charging up to 70% in just two minutes.
Lithium ion batteries lasts up to two to three years are used in mobile phones, tablets and electric vehicles, but the battery developed by NTU Scientists claimed to last up to 20 years.
Scientists have replaced the traditional graphite used in anode in the battery with a new gel material made from titanium dioxide.
The team converted titanium dioxide into tiny nanotubes responsible for superfast charging of the battery.
NTU Assoc Prof Chen Xiaodong expects the batteries to get commercial release in the next two years.
The batteries are expected to overcome power issues related to electro-mobility where recharge time is more yet the battery life is less.
Manufacturing nanotube gel is very easy according to Prof Chen, and battery manufacturers will be able to integrate the new gel into their current production processes.
NTU professor Rachid Yazami said, "There is still room for improvement and one such key area is the power density – how much power can be stored in a certain amount of space – which directly relates to the fast charge ability."
"Ideally, the charge time for batteries in electric vehicles should be less than 15 minutes, which Prof Chen’s nanostructured anode has proven to do so."
