Clay-Like MXene Ti3C2Tx (LiF Etching) as Cathode Host for Aqueous Zn-I2/Br2 Battery, 5 g/bottle, CAZIBCCMTCT

Clay-like Ti3C2Tx MXene, produced via the Minimally Intensive Layer Delamination (MILD) method using an LiF etchant solution, represents one of the most versatile and high-performance physical forms of MXene for advanced energy storage. When applied as a cathode host matrix in aqueous zinc-iodine (Zn-I2) or zinc-bromine (Zn-Br2) batteries, this clay-like morphology offers distinct processing and electrochemical advantages over traditional accordion-like powders or vacuum-filtered films.

The key functional features of Clay-like Mxene Ti3C2Tx are: (1) Direct Processability & High Active Loading: Because of its viscous, moldable texture, clay-like MXene can be directly blended with high-purity iodine (I2) or bromine precursors and rolled, extruded, or doctor-bladed into thick-film electrodes without requiring complex polymeric binder slurries or hazardous organic solvents (like NMP). (2) Enhanced Polyhalide Confinement: The enriched -O and -OH surface terminations act as strong chemical anchoring sites. They exhibit high adsorption energy toward intermediate polyhalide species (I3^-, Br3^-), effectively trapping them at the cathode and preventing the destructive shuttle effect. (3) Superior Compaction & Volumetric Energy Density: Unlike fluffy, highly expanded accordion-like MXenes that suffer from low tap density and excessive void space, clay-like MXene pastes can be mechanically consolidated or calendered to achieve higher compaction densities. This maximizes the volumetric energy density of the halogen cathode without entirely collapsing the ion-transport channels. (4) Metallic Conductivity & Fast Kinetics: It maintains the intrinsic high electrical conductivity of 2D transition metal carbides, ensuring rapid electron transfer to the insulating iodine or halogen-complexed species during fast charge-discharge cycles.
