New Technology: Quantum Battery turned out to be one more lithium battery opponents

With the continuous improvement of mobile devices, battery life will be stretched, so all kinds of wireless charging technology and fast charging technology is widely mentioned, but it is not easy to popularize. To solve the fundamental problem of battery life, some researchers recently started to develop a quantum battery.

The physicists from Britain, Italy and other four countries proved the feasibility of quantum batteries in the New Physics magazine of the British Physics Society (IOP). The quantum acceleration caused by the entanglement of multiple quantum bits can speed up the charging process. Therefore, Quantum battery charging faster than the traditional battery.

According to reports, the quantum cell quantum bits can be ions, neutral atoms, photons and other forms, charging that the qubit will change from a low energy state to a high energy state, while the discharge is the opposite.

Quantum bit is an important factor in determining the length of the quantum charge. The researchers found that in the charging process, the entangled quantum has a shorter distance between low and high energy states than the non-entangled quantum, and the more the quantum bits and the stronger the entanglement, the faster the charging process will be. The charging time is inversely proportional to the number of qubits.

John Gould, a physicist at the Abdus Salam International Center for Theoretical Physics in Italy, said: "Quantum systems have several orders of magnitude smaller electricity storage capacity than conventional electrical equipment. We have only theoretically proven that in giving a When the system inputs energy, quantum physics can bring about acceleration. "

However, there are still limitations of the above-mentioned technologies. The work of a quantum battery is not a disorderly energy release, and can not guarantee its normal and effective work. In addition, the quantum battery requires electricity for devices such as mobile phones and electric vehicles, too small. So, after the quantum battery technology is mature, lithium batteries will be eliminated?
