AMSTERDAM, The Netherlands – Can we expect an imminent breakthrough in battery technology and with that in cheap energy storage systems? It’s not there yet; but something is appearing at the horizon. It’s about batteries fitted with electrodes made out of wood!
Science, the world’s leading journal of original scientific research, is publishing an article on the first research results of a Polish-Swedish group. Their study is called: “Searching for a better thermal battery.”
Main ingredients of wood
Their initial results point at electrodes made out of lignin with polypyrrole. Lignin together with celluloses are the main ingredients of wood. The current energy storage systems are made with rare and expensive metals like cobalt.
New electro-active substance
As in the near future electrical energy consumption is expected to explode; there is a big need for cheap battery materials that can be recycled. Will lignin and polypyrrole collected from trees bring that material? The Polish-Swedish research is still in its early stages. But the article in Science describes in detail the galvanic preparation of thin layers of a new electro-active substance on electrodes.
