HANGZHOU, Dec. 23 (Xinhua) -- A team of researchers from Zhejiang University have developed a new type of aluminum-graphene battery that can be charged in seconds, instead of hours.

The team, led by professor Gao Chao, from Department of Polymer Science and Engineering of Zhejiang University, designed a battery using graphene films as anode and metallic aluminum as cathode.

The battery could work well after quarter-million cycles and can be fully charged in seconds.

Experiments show that the battery retains 91 percent of its original capacity after 250,000 recharges, surpassing all the previous batteries in terms of cycle life.

In quick charge mode, the battery can be fully charged in 1.1 seconds, according to Gao. The finding was detailed in a paper recently published in Science Advances.

The assembled battery also works well in temperatures range of minus 40 to 120 degrees Celsius. It can be folded, and does not explode when exposed to fire.

However, the aluminum-ion battery cannot compete with commonly-used Li-ion batteries in terms of energy density, or the amount of power you can store in a battery in relation to the size, according to Gao.

"It is still costly to make such battery. Commercial production of the battery can only be possible until we can find cheaper electrolyte," Gao said.
