Batteries & battery technology
Looking at battery technology and developments.
An hour long video (58:32min) from Michigan Engineering; looking at batteries of the future. It is a series of lectures centred round the physical chemistry of the various battery types and how this affects their future development and usefulness.
It discusses the Lithium-Oxygen / Lithium-Air battery which, if it is ever realised promises great things but, it has some serious problems. IBM are part of a consortium involved in their development with the 'Battery 500' project; the aim, to develop a Lithium-Air battery with a range of 500 miles between charges. (February 2013)
Hopes are riding on electric motors to power the cars of the future. Their Achilles heel is the batteries. They're too heavy, too short-lived and take too long to re-charge.
Now researchers at the Karlsruhe Institute of Technology (KIT) are working on a new type of battery that doesn't employ either lead or lithium.
They're using metal fluoride to store three times the charge of current in state-of-the-art batteries. (February 2012)
