Abstract

Direct atomic layer deposition (ALD) on composite electrodes leads to ultrathin conformai protective coatings without disrupting inter-particle electronic pathways. Al2O3coated 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 NC. (Figure Presented)
