Samsung researchers have developed a new battery material that could recharge your mobile phone in just 12 minutes. It could help your phone last much longer off a single charge. Samsung also says that the batteries are perfect for electric vehicles.

The company has announced that researchers at the Samsung Advanced Institute of Technology (SAIT) have developed a new battery material it is calling a “graphene ball”.

According to Samsung, a battery based on graphene ball technology can be charged five times faster than a standard lithium-ion battery. This material can also boost battery capacity by up to 45 per cent, which is a huge increase.

In theory, a battery based on the ‘graphene ball’ material requires only 12 minutes to fully charge,” says Samsung.

Additionally, the battery can maintain a highly stable 60degree Celsius temperature, with stable battery temperatures particularly key for electric vehicles.

The new battery technology developed by Samsung SDI and its partners uses the graphene balls (a 3D structure synthesized from silicon dioxide, Si02) to cover cathode and anode material. Graphene balls on the cathode suppress damaging side reactions while also providing efficient conductive pathways. This enables faster charging (as graphene features 140 times faster electron mobility than silicon) and increases the number of cycles a cell can withstand.

According to Samsung, a battery cell featuring graphene balls has a 27.6% higher volumetric energy density compared to a similar cell without graphene balls. Furthermore, the cell also retains 78.6% of its capacity after 500 cycles at between 5°C and 60°C.

Dr. Son In-hyuk, who led the project on behalf of SAIT, said, “Our research enables mass synthesis of multifunctional composite material graphene at an affordable price. At the same time, we were able to considerably enhance the capabilities of lithium-ion batteries in an environment where the markets for mobile devices and electric vehicles is growing rapidly. Our commitment is to continuously explore and develop secondary battery technology in light of these trends.
