Researchers from Maryland University, USA, have come up with a bold idea of new battery material. The new battery composed of a sliver of wood coated with tin. It has shown promise for being compact and tiny,
long-lasting, efficient and environmentally friendly energy storage. The team
thinks that this wood-based batteries would be best suited
for large-scale energy storage due to the relatively
low cost of the materials involved.
The idea was inspired by wood fibers from trees are supple and naturally designed to hold
mineral-rich water, which is very similar to the electrolyte in
batteries. Using wood sliver also helps to solve the problem of today's sodium-ion batteries
often use stiff, non-flexible substrates, which are too rigid to release
the stress that occurs as ions flow through the battery.
The wood battery has already shown itself to
be rather promising. It has successfully lasting through a full 400
charge-discharge cycles.
Commercializing this technology doesn't seem to be hard as none of
the materials involved are very expensive and the manufacturing
doesn’t seem as though it would be very expensive either.
