Abstract

Direct atomic layer deposition (ALD) on composite electrodes leads to ultrathin conformal protective coatings without disrupting inter‐particle electronic pathways. Al2O3‐coated natural graphite (NG) electrodes obtained by direct ALD on the as‐formed electrode show exceptionally durable capacity retention even at an elevated temperature of 50 °C. In sharp contrast, ALD on powder results in poorer cycle retention than bare NG.
