An international team of scientists has revived Thomas Edison's concept for a nickel-iron battery, aiming to improve renewable energy storage. Edison envisioned this battery design in the early 20th century as a potential alternative to lead-acid batteries for electric cars, believing it could offer a 100-mile range and a seven-hour recharge time. The researchers drew inspiration from nature, using beef byproduct proteins and graphene oxide to create a carbon scaffolding. This aerogel structure, formed by superheating and baking the ingredients, significantly increased the surface area for chemical reactions. The resulting prototype demonstrated rapid recharging in seconds and remarkable durability, enduring over 12,000 cycles, equivalent to approximately 30 years of daily use. While its storage capacity currently lags behind lithium-ion batteries, the design shows promise for storing energy from renewable sources like solar farms.
