The development of batteries to today, especially lithium batteries are very close to their theoretical physical limits, we very much need the innovation
of battery materials, technology and form.
Recently, Kavan Modi and colleagues from Monash University in Australia added a surprise to the battery community: using quantum technology to greatly reduce charging time
.
Quantum-based technologies have many advantages over traditional techniques, and the team considered nanoscale battery models
with quantum energy states.
They found that if multiple identical quantum batteries interacted, charging times could be greatly reduced, and surprisingly, they were not entangled
with each other.
Recent studies have shown that when the same several batteries are put together and let them interact, more power
can be extracted from quantum batteries.
So Modi and his collaborators saw the dawn
of reverse-charging quantum batteries.
The team imagined several identical quantum cells, each moving from an initial low-energy state to a higher-energy (charged) state
through some external field measure.
Previous studies of the so-called "quantum speed limit" have found that when different subsystems – the batteries – interact with each other in this case, the time required
to go from the initial to the final quantum state can be shortened.
The research team showed that N quantum batteries in a statistical mix of nonlinear states can be charged N times
by interactively rather than independently.
This is a study with theoretically infinite possibilities, and hopefully the team will bring us more surprises
