MOF derived composites for cathode protection: coatings of LiCoO 2 from UiO-66 and MIL-53 as ultra-stable cathodes

A mechanochemical synthetic method of preparing LiCoO2 coated by MOF-derived metal oxide composites is introduced. Mono-dispersed ZrO2 and Al2O3 are applied as protection layers. These composites show 148 mA h g(-1) at a current density of 2325 mA g(-1) and excellent thermal stability (55 °C).
