Samsung develops battery technology that charges five times faster

Smartphone charging Samsung develops new battery technology than could charge your phone in just 12 minutes 0

As well as having a much larger capacity, this new graphene based battery will be able to charge much faster than current batteries.

The firm's lithium-ion batteries - like the one found in the Galaxy Note 8 - take a little more than an hour to charge from zero, depending on the model.

Finally, the graphene ball batteries are reportedly capable of maintaing workload temepratures of around 60 degrees Celsius, making them a prime candidate for use in future electric cars.

The full findings of SAIT were published on Nature this month.

SAIT's team used a chemical vapor deposition process to grow a graphene-silica assembly, called a graphene ball. Unsurprisingly, Samsung has already patented the technology in South Korea and the US. These "balls" were then used as material for advanced lithium-ion batteries.

Lithium-ion batteries were first commercialized in 1991 and have since been the standard for use in electronic devices.

An organic light-emitting diode (OLED) display was successfully created using transparent electrodes made by graphene, a promising advanced material, by Korean researchers. Samsung says that this new technology is going to reduce the charging time of lithium-ion batteries to just 12 minutes. The graphene-ball coating improves cycle life and fast charging capability by suppressing detrimental side reactions and providing efficient conductive pathways. Samsung is developing a new battery that could bring significant changes to smartphone batteries.
