JGu Demertri Budke Professor Hu Yunan has a battery unit and a device for measuring the state of charge. Rechargeable battery is the core of many new technologies, for example, new use of renewable energy. In more detail, they are used for electric vehicles, mobile phones and laptops.

German Meizi Johnnes Gitten Fort University (JGU) and the Simo Himhumholz Research Institute (HIM) proposed a non-contact method to test the charging state and any defect of lithium-ion batteries. To this end, the atomic magnetometer is used to measure the magnetic field around the battery unit. Professor DmitryBudker and its team usually use atom magnetic methods to study basic problems of physics, such as looking for new particles.

Magnetic gauge is used to describe the terms measured by magnetic field measurement. A simple example of the compass is that the contaminable quality of the compass on the earth uses the non-contact quality of the battery of the atom magnetometer to ensure that the demand for large-capacity rechargeable batteries is therefore regarding the determination of the smart and accurate diagnosis technology of the battery. Many new developments will depend on whether it can be processed to supply sufficient capacity and long life.

UGqr. ARNEWITNBROCK, Working Group, Professor DmitryBudker, JGU Physics, said: "Quality assurance for rechargeable batteries is a huge challenge. Non-contact methods may supply new motivation for improved battery quality.

"Helmhoz Research. The team broke through by using an atomic magnetometer. This idea is proposed in the conference call between Budker and his New York University Colleague Alexejerschow.

"Our technology is essentially the same as the working principle of magnetic resonance, but it is simpler because we use atom magnetometer", the team's Wickenbrock of this study said. The atomic magnetometer is a light pump magnetometer that uses a gaseous atom as a probe of a magnetic field. They are commercially available, and they are used for industrial use and basic research.

The Budker team of JGU and HIM has also developed its own advanced magnetic sensor, and they use these atom magnetisms for physics basic research, such as looking for dark matter, and trying to handle riddles in substances and anti-substances. Immediately destroy each other. Simple approach can realize fast and high-throughput measurements in the case of battery measurement, place the battery in the background magnetic field.

The battery will change the background magnetic field and measure changes to the atomic magnetometer. Wickenbrock added: "This change provides us with information about battery charging, residual power and possible damage. "The process is very fast, we think it can be easily integrated into the machining process.

". "Refudited reports on electronic smoke explosions and limited injuries to certain types of mobile phones carrying some types of mobile phones, to test the defects in the battery. The author points out in the nearest PNAS paper: "The diagnostic ability of this technology is expected to evaluate cells during research, quality control or operation.

"Last summer, the same Working Group organized two activities related to using atoms and nuclear physics, with international high-level participation. About 200 researchers from all over the world answered current atomic magnetic force measurement and other forms of quantum measurement technology issues. .
