Poly(ethylene) microspheres are prepared by S. R. White and co‐workers via a solvent evaporation technique and used to demonstrate autonomic shutdown of a Lithiumion battery operating unsafely. These ca. 4 μm diameter microspheres can be coated directly onto an electrode surface, as shown on page 583 . When the internal battery environment reaches a critical temperature (110 °C), the microspheres melt and form a conformal coating on the electrode surface, effectively halting Li‐ion transport and permanently shutting down the battery cell.
