Bulletproof batteries (Day 259)

Lithium batteriesLithium ion batteries are used as high density power sources for a range of devices from mobile phones (see my blog ‘The next generation of ultra-fast charging batteries‘) to electric vehicles.

But the use of lithium batteries hasn’t been without some issues. For example, in 2013 Boeing was forced to ground its entire 787 Dreamliner fleet after problems were detected with the lithium ion batteries in the plane’s electrical system.  The batteries reportedly burst into flames under some conditions – not a good state of affairs at 43,000 feet!

This safety issue obviously requires addressing, so researchers at the University of Michigan (U-M), US, have been working to develop an advanced type of barrier between the electrodes in a lithium-ion battery.
