Research news: Silicon anodes may help to improve lithium-ion battery capacity

Lithium ion batteries are widely used in mobile electronics and already have been deployed in data centers as part of Uninterruptible Power Supply systems as well.

Researchers from the University of Eastern Finland introduced new technology to Li-ion batteries by replacing graphite used in anodes by silicon. Without using nanoparticles it is possible to quadruple anode capacity, the researchers say.

But the research is still at early stage. “We now have a good understanding of the material properties required in large-scale use of silicon in Li-ion batteries. However, the silicon we’ve been using is too expensive for commercial use, and that’s why we are now looking into the possibility of manufacturing a similar material from agricultural waste, for example from barley husk ash,” Professor Vesa-Pekka Lehto explains.
