A newly developed battery could keep the lights on in low-income countries with minimal cost, helping the world meet pollution reduction goals without sacrificing modern comfort, reports TCD.

Tech Xplore reported that researchers at Sweden's Linkoping University created a modest but effective battery that can be used more than 8,000 times without dipping below 80% of its performance capabilities.

To do this, they used zinc and lignin. The combination resulted in a battery with a similar energy density to lead-acid products without the harmful toxins. Unlike other zinc-based batteries, which lose their charge in just hours, the zinc-lignin product can last for around one week.

Linkoping University professor of organic electronics Reverant Crispin believes the technology could be a crucial tool as developing countries invest in their infrastructure, ensuring clean energy is reliably available.

Lithium-ion batteries are currently used to power most electric vehicles, a more planet- and lung-friendly mode of transportation because of the lack of tailpipe pollution. They are also used for renewable energy storage, something that is crucial as the world phases out dirty fuels.

However, as detailed by the US Department of Energy, these batteries are generally more expensive, and there's the risk of very rare but serious fires.
