Polímero de algas pode melhorar baterias

(Notícia em Inglês)
By looking to Mother Nature for solutions, researchers have identified a promising new binder material for lithium-ion battery electrodes that not only could boost energy storage, but also eliminate the use of toxic compounds now used to manufacture the components.

Known as alginate, the material is extracted from common, fast-growing brown algae. In tests so far, it has helped boost energy storage and output for both graphite-based electrodes used in existing batteries and silicon-based electrodes being developed for future generations of batteries.

The research, the result of collaboration between scientists and engineers at Clemson Univ. and the Georgia Institute of Technology, is being reported in Science Express, an online-only publication of the journal Science that publishes selected papers in advance of the journal. The project was supported by the two universities as well as by a Honda Initiation Grant and a grant from NASA.
