As the functions of mobile devices continue to improve, the battery life is stretched, so various wireless charging technologies and fast charging technologies are widely mentioned, but it is not easy to popularize. In order to solve the fundamental problem of battery life, researchers have recently begun to develop a quantum battery.
The physicists of the four countries of Britain and Italy have proved the feasibility of quantum cells in the Journal of New Physics of the British Physical Society (IOP). The "quantum acceleration" caused by the intertwining of multiple qubits can accelerate the charging process, so Quantum battery charging is faster than traditional batteries.
According to reports, the quantum bits in a quantum battery can be in the form of ions, neutral atoms, photons, etc. Charging means that the qubits are changed from a low energy state to a high energy state, and the discharge is reversed.
Quantum bits are an important factor in determining the length of quantum charging time. The researchers found that in the charging process, the entangled quantum passes a shorter distance between the low energy state and the high energy state than the quantum without entanglement, and the more the quantum bits, the stronger the entanglement and the faster the charging process. The charging time is inversely proportional to the number of quantum bits.
New technology: quantum battery turned out to be a lithium battery and another opponent
John Gould, a physicist at the International Center for Theoretical Physics at Abdul Salam, Italy, said: "The storage capacity of quantum systems is orders of magnitude smaller than that of everyday electrical equipment. We just theoretically proved that we are giving Quantum physics can bring acceleration when the system inputs energy."
However, the above technology still has limitations. The work of quantum cells is not disorderly energy release, and it cannot guarantee that it can work normally and effectively. In addition, the storage capacity of quantum batteries for the power consumption of mobile phones, electric vehicles and other equipment. too small. So, after the quantum battery technology is mature, will lithium batteries be eliminated?
