In the present study, a manganese (Mn) oxide deposited hierarchical cobalt (Co) oxide structure was prepared as a supercapacitor electrode by a two-step hydrothermal process. A Co-oxide hierarchical structure was first prepared as a template on a graphite substrate by hydrothermal and post heat treatment (calcination) processes. Subsequently, the Mn-oxide was deposited onto the surface of the Co-oxide...
Carboxymethyl cellulose (CMC) is a commonly used thickening agent for water-based lithium (Li) ion batteries. Addition of CMC improves the electrochemical properties of most electrodes but excessive amounts may cause the corresponding electrode slurries to gel, making it unfavorable for casting. This study investigates the gelation mechanism of CMC with the popular active cathode material lithium...
