Biomass could yield green batteries

Turn an acid found in plants into a salt, add a dash of lithium, and you have a recipe for environmentally benign batteries.

Lithium-ion batteries are widely used in electronic devices including computers, and in some electric and hybrid electric vehicles. The minerals used to make today's lithium-ion batteries are a limited resource and require high temperature processing, which emits carbon dioxide.

An alternative is using phytic acid -- widely found in grains and seeds -- to produce tetrahydroxybezoquinone, which, in turn, can be processed into a lithium salt suitable for batteries.

These all-organic batteries operate at voltages that are too low to be practical, but future research promises to improve their performance.
