Hexagonal boron nitride (hBN) is widely used in batteries to improve safety, thermal management, and performance by acting as an electrically insulating yet highly thermally conductive material. This prevents thermal runaway, a dangerous overheating event, especially important in electric vehicle (EV) batteries. Its electrical insulation prevents short circuits between cells or with other components.

With Star Burst wet jet milling, hBN can be exfoliated in water or other solvents. The technology exfoliates hBN layers by collision, all while preserving the aspect ratio of the materials.

This approach significantly enhances the thermal conductivity and the electrical insulation performance of hBN.
