The first hours of a lithium-ion battery’s life largely determine just how well it will perform. In those moments, a set of molecules self-assembles into a structure inside the battery that will affect the battery for years to come.

Researchers from Virginia Tech’s Future Materials Laboratory and MInDS Laboratory have recently demonstrated that high-intensity focused ultrasound (HIFU) is a promising, non-invasive stimulus with multiple superior and unique capabilities to induce localized heating and achieve temporal and spatial thermal effects in polymers.
