There is a growing need for high power electrochemical cells, in particular rechargeable batteries for use in portable electronic devices.  One development is the use of nanomaterials.  Nanomaterials provide a high surface area which has the potential to provide a higher reaction rate.  However this may also increase less desirable side-reactions, reducing the safety of the cells.  Therefore the search for stable materials is important.

In his Dalton Perspective, Stanley Whittingham from the State University of New York, USA looks at the opportunities and challenges for inorganic nanomaterials and their applications in the anode, cathode and electrolyte components of electrochemical cells for energy storage.  Lithium-transition metal oxides and phosphates are highlighted, as well as tin-cobalt alloys.

Nanomaterials have a key role to play in the next generation of batteries, Whittingham says.
