Zinc–iodine battery with outstanding stability now a reality

18-Jun-2025 - Researchers at the University of Adelaide have developed a new dry electrode for aqueous batteries which delivers cathodes with more than double the performance of iodine and lithium-ion batteries. “We have developed a new electrode technique for zinc–iodine batteries that avoids traditional wet ...

Using batteries to produce hydrogen peroxide from air for industrial applications

"This method is very sustainable, low-cost, and highly energy-efficient"

12-Mar-2025 - Hydrogen peroxide (H2O2) is widely used as a bleach, disinfectant, and oxidising agent, among other things. However, industrial production ofH2O2is expensive and uses a lot of energy owing to the rare and precious metal catalysts used in its production. Researchers at the Indian Institute of ...

Fresh iron from old mining sludge

Great interest in pilot plant

06-Dec-2024 - It sounds like utopia: mining sludge is transformed into valuable metals and new building materials. Over the past three years, researchers at TU Bergakademie Freiberg have successfully trialled this innovative process in a pilot plant. The team succeeded in extracting iron and zinc from mining ...

On the way to emission-free mining: extracting metals with microorganisms

Innovative process for the bioleaching of copper, indium and zinc developed

12-Jul-2024 - Microorganisms work in an underground bioreactor and convert ores or residual materials from mining into the valuable metals copper, indium and zinc. Innovative membrane filters then filter the valuable metals from the resulting process water. In a pilot plant of a current mining project near ...

Density matters for better battery material performance

Key to better electrochemical performance found?

23-Nov-2023 - Zinc — cheap, abundant, environmentally friendly — may be the answer to better batteries, but there’s a major problem: Aqueous zinc ion batteries (AZIBs) cannot match lithium-ion batteries in terms of power output. To test what electrode material composition might be able to bring AZIBs up to ...

New energy storage system combines battery and electrolyser

Tool for the energy transition: Only one tenth of the material costs of a lithium-ion battery

11-Oct-2023 - A research consortium with the participation of TU Berlin is working on a novel zinc-hydrogen battery that can store electricity with a high degree of efficiency and releases not only electrical energy but also hydrogen when discharging. This is achieved by combining the negative zinc electrode ...

Ecological Revolution: Zinc batteries with double efficiency and the ability to produce hydrogen

27-Jul-2023 - The renewable energy revolution wants to build a climate-friendly future for the world. But the move away from fossil fuels will remain a challenge as long as efficient means to store green energy are still lacking. A research consortium has set itself the goal to tackle exactly this problem with ...

Meteorites reveal likely origin of Earth’s volatile chemicals

Outer Solar System played a bigger role than previously thought

03-Feb-2023 - By analysing meteorites, Imperial researchers have uncovered the likely far-flung origin of Earth’s volatile chemicals, some of which form the building blocks of life. They found that around half the Earth’s inventory of the volatile element zinc came from asteroids originating in the outer ...

A paper battery with water switch

Just add a drop of water

02-Aug-2022 - A team of researchers at Empa developed a water-activated disposable paper battery. The researchers suggest that it could be used to power a wide range of low-power, single-use disposable electronics – such as smart labels for tracking objects, environmental sensors and medical diagnostic devices ...
