(June 01, 2015) A
method for making elastic high-capacity batteries from wood pulp was unveiled
by researchers in Sweden and the US. Using nanocellulose broken down from tree
fibres, a team from KTH Royal Institute of Technology and Stanford University
produced an elastic, foam-like battery material that can withstand shock and
stress.
"It is possible to make incredible materials from trees
and cellulose," says Max Hamedi, who is a researcher at KTH and Harvard
University. One benefit of the new wood-based aerogel material is that it can
be used for three-dimensional structures.
