Magnetic resonance imaging (MRI) machines for batteries have been developed in the United States

A team of New York university scientists have developed an easier way to test a battery pack, which is usually dismantled to see its structure and damage.

Rise of 3 c products is growing with electric cars, people more and more need to safe and efficient battery, the battery detection way is still stagnant, professor of chemistry at the university of New York Alexej Jerschow, said the current can only a few tools under limited conditions, to diagnose without causing damage to the battery, the team developed a new type of machine, can with noninvasive technology provides more rapid and scalable detection method.

Lithium ion Battery safety controversial in recent years, also highlighted the Battery design and manufacture difficulties at the same time, maintenance engineers often have to disassemble the Battery to diagnose the Battery status, or even remove after to detect the flaw, therefore at New York university and the rochester institute of technology, the Battery prototype Center (' Prototyping Center) cooperation, want to find out do not disassemble the Battery can accurately detect the way, is expected to improve electric safety in the future.

Medical development today, for example, there are also many check non-intrusive way, such as magnetic resonance photography, principle, it is concluded that high resolution images of the magnetic fields, check without the anatomy of the human organs with condition and allow doctors more accurate diagnosis, the team also USES a similar process, by measuring the battery electrochemistry around the small magnetic field changes, to test whether the battery health.

According to its research in Nature Communications, the team used the technology to examine lithium-ion batteries in different states, including different battery life and damage conditions, and to compare changes in the magnetic field around the battery with changes in different battery states to work out the charging state of the battery and other battery defects. Electrode bending and defects and small foreign bodies are possible defects in the manufacturing process.

Matthew Ganter, a scientist atthe RIT battery prototype center, said the battery manufacturing process is important to ensure the quality and safety of the battery, while also saving businesses a lot of money and preventing future catastrophic battery failures. Christopher Schauerman, another scientist, says the work could strengthen not only the battery industry as a whole, but also New York's growing energy storage system.

Jerschow also said that as the technology matures, the machine is expected to predict battery failures and battery life in the future, and contribute to the development of the next generation of high-efficiency, high-capacity, long-life or fast-rechargeable batteries.
