Technology that could cut charging time to a fraction of a second — with a Polish scientist’s contribution

From smartphones to energy storage systems, today’s world runs on lithium-ion batteries. They power about 70% of all rechargeable devices — from everyday electronics to electric vehicles. Lithium has become the foundation of modern portable energy: it’s light, efficient, relatively inexpensive, and widely available. However, its extraction and processing are linked to environmental degradation, health risks, and geopolitical tensions in the supply chain.

As a result, more and more scientists are seeking alternative solutions. One of the most promising research directions is quantum batteries — a technology that, just a decade ago, existed only as a theoretical concept. The idea was developed by Robert Alicki from the University of Gdańsk and Mark Fannes from KU Leuven. Today, research teams around the world are working on making it a reality.

Charging in the blink of an eye — and energy from light

Quantum batteries store energy in the form of photons, rather than ions or electrons, opening entirely new possibilities. In theory, they could charge many times faster than current cells and even store energy directly from light. What’s more, theoretical models suggest that, under certain conditions, they could release more energy than they absorbed — if they share a quantum state with the powered device.

While it sounds like science fiction, real progress is being made in laboratories. Scientists at the Royal Melbourne Institute of Technology in Australia have created a prototype that retains energy 1,000 times longer than earlier designs — from nanoseconds to microseconds. Francesco Campaioli from the research team compares it to a phone that charges in half an hour and can last 20 days in standby mode.

From prototype to practice

The road to commercial application is still long. The biggest challenge is precisely controlling energy storage and release in a world where the laws of quantum physics can be unpredictable. Experts emphasize that the success of this technology could revolutionize power supply for small devices — particularly the Internet of Things, sensors, and autonomous off-grid systems.

Quantum batteries will not replace lithium-ion batteries in electric cars or large-scale energy storage. However, they could fill a niche, offering compact, integrated power sources that simultaneously store and process energy — much like a solar panel with a built-in battery.

A future written in photons

If researchers manage to overcome the technical barriers, quantum batteries could reach our pockets sooner than expected and significantly change the way we charge and power everyday devices.
