Lithium-ion batteries are currently the preferred technology to power electric vehicles, but they're too expensive for long-duration storage

With the rapid reduction in the costs of renewable energy generation, there is a growing need for energy storage technologies.

Researchers have developed a low-cost device that can selectively capture carbon dioxide gas while it charges.

Millions of people around the world lack access to electricity. Decentralised solar-battery systems are key for addressing this problem.

Researchers have used a widespread species of blue-green algae to power a microprocessor continuously for a year—using light and water.

Hydrogen fuel cells convert hydrogen to electricity with water vapour as the only by-product, making them an attractive green alternative.

Turmeric and gold are used to create an electrode that requires 100 times less energy to efficiently convert ethanol into electricity.

In the constant search for environment-friendly alternatives to lithium-ion batteries, proton batteries are proven to have great potential.

Red bricks — some of the world’s cheapest and most familiar building materials — can be converted into energy storage units.

Hydrogen fuel cells convert hydrogen to electricity with water vapour as the only by-product, making them an attractive green alternative.

Researchers have optimized the design of a nuclear battery generating power from the beta decay of nickel-63, a radioactive isotope.

Researchers developed rechargeable batteries that can store up to six times more charge than ones that are currently commercially available.

From flat battery to full charge in just five minutes -- an Israeli start-up has developed technology it says could eliminate range anxiety.

Molten-salt battery locks in energy for months without losing capacity and marks step toward seasonal storage of grid-scale energy.

Researchers developed a material that could give fuel cell systems a competitive edge over battery systems that currently power most EVs.

Lithium-ion batteries, fuel cells and many other devices depend on the high mobility of ions in order to work properly.

Physicists have discovered a new way to coat soft robots in materials that allow them to move and function in a more purposeful way.

The system hoists 30 tonne “mobile masses” into the air using excess energy. When the need arises for the power, the mass descends.

Solid-state batteries, currently used in small electronic devices like smart watches, can be safer and more powerful than lithium-ion cells.
