All Charged Up: Engineers Create a Battery Made of Wood
18th July 2013
The “wood” is actually microscopic wood fibers that are fashioned into thin sheets. The sheets are then coated with carbon nanotubes and packed into small metal discs.
The wood batteries use sodium ions, rather than the lithium ions that are found in the batteries of cellphones and laptops. In this case, the charged particles move around in the wood fibers, creating an electric current. It turns out wood is a good medium for sodium ions to move around in.
We have the technology.
