Over the past few years, some researchers have been working on alternative energy storage systems that leverage the principles of quantum mechanics. These systems, known as quantum batteries, could be more efficient and compact than conventional battery technologies, while also achieving faster charging times.
In a recent paper published in Physical Review Letters, a research group at University of Genova introduced a new spin quantum battery, a battery that leverages the spin degrees of freedom of particles to store and release energy. This battery is charged in a unique and advantageous way, without the need for an external field.
