Simple Self-Charging Battery Offers Power Solutions for Devices

A new type of battery combines negative capacitance and negative resistance within the same cell, allowing the cell to self-charge without losing energy, which has important implications for long-term storage and improved output power for batteries. In Applied Physics Reviews, researchers at the University of Porto and the University of Texas at Austin report making their very simple battery with two different metals, as electrodes and a lithium or sodium glass electrolyte between them.
