Revolutionary warm paste technology transforms into emergency power source in minutes (IMAGE)
Caption
Researchers have developed a novel method to transform commercially available warm pastes into functional iron-air batteries for emergency power generation. The technology redirects the chemical energy that would normally produce heat (reaching temperatures up to 41°C as shown in thermal imaging) into electrical energy instead. The conversion process involves reconfiguring the warm paste's iron-based materials by adding hydrogel layers and catalysts to create electrochemical reactions (Cathode: O2 + 2H2O + 4e− → 4OH−; Anode: Fe + 3OH− → FeOOH + H2O + 3e−). This innovative approach repurposes the same chemical energy source - transforming heat-generating warm pastes into electricity-producing batteries through a simple assembly process involving non-woven powder backing layers and catalyst components.
