Lithium iron phosphate is a widely used cobalt-free cathode material for lithium-ion batteries. It is known to experience certain kinds of defects in its crystal structure, however, and a recent study led by researchers at the Skolkovo Institute of Science and Technology explores the existence of hydroxyl groups in phosphorus vacancies.

Researchers often use similar defect models for barium titanate and strontium titanate even though the materials experience different dominant metal vacancies. New research suggests this practice is suitable in some cases, but researchers should tread more carefully in others.

New research from MIT shows that firmness isn’t the most important parameter for developing a solid electrolyte that is effective against dendrite formation—instead, a defect-free surface, which doesn’t provide a place for dendrites to form, is key to a better battery.
