It is the first ever lithium-ion battery – the same type of battery found in everything from smartphones to solar energy storage systems – that is simultaneously high capacity, biodegradable, and capable of controlling remotely. “Our proof-of-concept application in animal models demonstrates an exciting new avenue of wireless and biodegradable devices for the management of arrhythmias.” Constructed from biocompatible hydrogel droplets, the battery can operate within a living body without interfering with its physiology. To date, it is the smallest hydrogel lithium-ion battery and has a superior energy density,” said Yujia Zhang from the University of Oxford’s Department of Chemistry, who led the research into the battery. By including magnetic particles to control movement, the battery can also function as a mobile energy carrier.” The research was published in the journal Nature Chemical Engineering on Friday, in a study titled ‘A microscale soft lithium-ion battery for tissue stimulation’.
