According to its inventors, the battery is made of graphite and aluminum and is safe, cheap, flexible and fast-charging.
The scientists tested the prototype and said that it charged from empty full in less than a minute.
The results of their project were published in the journal Nature, on April 6.
The researchers explained that in the near future, these batteries can be paired with flexible screens and power smartphones that can be folded and charged much faster than the ones today.
Smartphones run on electronic batteries made of lithium and ion.
However, Hongjie Dai, a professor of chemistry at Stanford University and one of the authors of the study, said that lithium-ion batteries are more likely to explode, compared to the aluminum-ion new battery.
The newly invented battery can also last longer than the usual lithium-ion batteries, according to professor Dai.
Usually, a lithium-ion battery can be recharged approximately 1,000 times before losing its full capacity.
Although previous aluminum-ion battery models lost their full capacity after 100 charges, the new one created by the Stanford engineers lasted for more than 7,500 charges without losing its capacity.
This kind of longevity, in combination with the safety of this battery, could one day be the perfect candidate for energy storage on the electric grid, according to the researchers.
Although this is an impressive invention, the battery is not ready yet to replace the lithium-ion one.
The scientists explained that the aluminum-ion battery only packs approximately half the voltage, meaning that one would need more than one battery to power a device.
Also, the new battery has less than one third energy density, compared to regular lithium-ion batteries, which makes the battery to be heavier.
The engineers claim that the new battery is a lot safer than lithium-ion batteries, which are currently used to power millions of devices like smartphones, tablets and laptops. These batteries are known to be a fire hazard.
In 2006, millions of batteries made by Sony had to be replaced because hundreds of them caught fire.
According to its inventors, the new battery can continue to work without catching fire even if it’s drilled through. Lithium batteries can go off unpredictably, whether it’s in the air, in the car on in someone’s pocket.
