Researchers create battery capable of keeping a smartphone running for 5 years

Lithium batteries are present in a variety of electronic equipment and devices, and scientists are currently developing ways to make them more effective and sustainable. A team of scientists say they have created the most efficient battery yet, promising more than 1,000 kilometers of autonomous vehicle or even keeping a smartphone running for five days, both without recharging.

According to the study recently published by researchers at Monash University, Australia, in the journal Science Advances, the developed lithium and sulfur battery is capable of storing four times more energy than currently available on the market. "The approach used not only enables high levels of performance and a long 'life cycle', but also reduces production costs and the production of environmentally harmful waste," says Matthew Hill, a member of the research team. , in press release.

To create it, the scientists used the same base found in typical batteries, reconfiguring the design of sulfur cathodes so as not to lose performance even in wear and tear. The project is in the prototype phase, but according to Mainak Majumder, one of the team's researchers, the project received more than $ 2.5 million for testing in 2020.

In addition to projects that promise to make lithium batteries more effective, there are also researchers looking for solutions for heavy metal addiction. The IBM Research Lab has developed a new type of battery technology that uses substances extracted from seawater.

The announcement of the new technology comes at a time when battery manufacturers are struggling to reduce the cobalt content in their products. As the electric vehicle market expands, the natural resource found mostly in the Democratic Republic of Congo has become increasingly scarce.
