TU Hamburg researchers develop energy storage system using pure water, challenging textbook electrochemistry

Summary

Researchers at the Technical University of Hamburg (TU Hamburg) have developed an energy storage system using pure water, challenging the established electrochemical principle that pure water cannot serve as an electrolyte due to its poor conductivity. The innovation involves trapping water in a confined space between graphene layers and clay, creating a capacitor-like storage system. This approach allows energy to be stored and released despite water's natural insulating properties, potentially offering a safer, more environmentally friendly alternative to conventional batteries and supercapacitors.
