Everything from our phones and computers to cars uses batteries. Batteries have become so ingrained in the western world that we often take their power and value for granted. But over the past couple of decades, thanks to the revival of the electric vehicle, batteries are gaining an improved reputation - holding great potential in the race toward climate change remediation.

A surge in the notoriety of EVs and renewable energy storage has researchers seeking ways to make alternative energy more efficient, cheaper, and more eco-friendly. Streamlined models deliver more promise for the future of all types of batteries outside the realm of the standard lithium-ion.

Researchers at the University of Adelaide emulated the potential of batteries with their recent venture into quantum batteries, a game-changer for the alternative energy sector.

Before we get into this breakthrough, we must first understand what a quantum battery is and how it differs from lithium-ion batteries.

One Step Closer

According to an article published by Medium, lithium-ion batteries differ from quantum in that the former relies on a set of chemical reactions within a cell, whereas the latter works based on Quantum Mechanic's four basic principles; physical state, physical quantity, composition, and dynamics.

With the theory of quantum mechanics, particles can maintain energy indefinitely. Hypothetically, quantum batteries could provide a no-loss energy supply and, following the concept of superabsorption, charge quicker.

A significant drawback with this theory is that it is just a theory. Proving the concept of superabsorption presents a major challenge.

This is where the team at the University of Adelaide comes into play. To navigate the theory of superabsorption, the team conducted varying assessments and constructed "several wafer-like microcavities of different sizes which contained different numbers of organic molecules. Each was charged using a laser."

Dr. James Q. Quach, who works in the School of Physical Sciences at the University of Adelaide, explained how the process was possible in an article published on the University's website:

"The active layer of the microcavity contains organic semiconductor materials that store the energy. Underlying the superabsorbing effect of the quantum batteries is the idea that all the molecules act collectively through a property known as quantum superposition."

The team found as "the microcavity size increased and the number of molecules increased, the charging time decreased." Findings are published in Science Advances.

Researchers have taken a significant leap in the journey to creating a usable quantum battery.

"The concepts that Dr. Quach and his team have worked on opens up the possibility of a new class of compact and powerful energy-storing devices," said Peter Veitch, a professor at the University.

The Possibilities of Quantum Batteries

Suppose quantum batteries were to be implemented into modern society successfully. There would no longer be a requirement to purchase as many batteries as often or to charge current batteries as frequently, effectively lowering the product's price point.

Further, the potential for use in various devices, like vehicles, computers, and phones, could help substantially lower our environmental footprint.

That isn't to say lithium-ion batteries aren't beneficial in their current state. But there's always room for improvement, and quantum batteries could provide a significant source of progress. The potential for quantum batteries could send ripples throughout the alternative energy arena, effectively promising a future with far fewer greenhouse gasses and a steady, affordable supply of energy.
