• ITMO Students Make a Battery That Can Be Wirelessly Recharged up to 500 Times

  In spite of their many disadvantages, batteries remain one of the key components in contemporary electronics. While changing their structure entirely is impossible due to the chemical and physical processes happening inside, scientists, startups, and major companies are searching for ways to reinvent them or adopt totally new approaches. One such approach was suggested by students of ITMO’s School of Physics and Engineering – their nine-volt battery can be recharged wirelessly with a regular smartphone charger. ITMO.NEWS breaks down the science behind the new device.

• Scientists Propose an Inkjet Printing Technology for Battery Elements to Make Them Compact and Flexible

  A group of St. Petersburg scientists has proposed a new method of manufacturing electrodes for lithium-ion batteries that power laptops, smartphones and tablets. The researchers have shown that these elements can be printed on an inkjet printer, which will reduce the electrodes’ thickness by 10–20 times and open up new opportunities for manufacturers of compact electronics. Their article has been published in the journal Energy Technology.
