This prototype quantum battery can now store up to 1000 times more energy than the previous battery device.

Quantum batteries in theory, can store more energy and charge faster than conventional batteries. But practically, they tend to lose all of their energy in nanoseconds. Scientists have developed a new prototype that can store energy 1000 times longer than previous devices.
The matter in quantum physics acts in a surprising way. Superradiance, a phenomenon where the energetic atoms release far more light pulse than they do individually. The reverse phenomenon of Superradicance is called Superabsorption, where the atoms cooperate to absorb light.
Francesco Campaioli, a researcher from Royal Melbourne Institute of Technology in Australia, with his team, experimented with triplet states, to prolong the life of quantum batteries. Triplet states are defined as the state of electrons in a molecule after absorbing the light energy. The researchers studied the state at which the electron tends to absorb light rather than to emit it, leading to storing energy longer in quantum batteries.
Two different layers of materials are needed, one layer containing the dye of Rhodamine 6G which absorbs light and transfers the absorbed light to the next layer. The next layer stores the light energy rather than emitting, and the second layer is made up of a compound called Palladium Tetrahenylorphyrin,
These layers are separated by a polymer and help light from a green 514 nanomenter laser to energise the device. These three layers help store light energy 1000 times longer than it enters the device.
Even this improvement seems negligible, as it only stores for microseconds, 1000 times than the nanoseconds. It is equivalent to having the phone charged in 30 minutes and in idle can run up to 20 days.
