AC6726 LiMn2O4 Single-Side Coated Aluminum Foil

LiMn2O4 Single-Side Coated Aluminum Foil Description

LiMn2O4 (LMO) Single-Side Coated Aluminum Foil is a specialized cathode material used in the development and prototyping of lithium-ion batteries. It consists of a uniform layer of lithium manganese oxide coated on one side of high-purity aluminum foil, which acts as a lightweight and conductive current collector. LiMn2O4 is valued for its three-dimensional spinel crystal structure, which allows for excellent lithium-ion diffusion, leading to high-rate capability and fast charging performance.

This cathode material is known for its superior thermal stability, safety, and environmental friendliness compared to cobalt-based materials. It operates at a voltage plateau of around 4 V vs. Li/Li⁺, providing moderate energy density and good cycling stability. The single-side coating design makes it ideal for controlled laboratory studies, allowing researchers to investigate cathode behavior under various test conditions.

The foil is manufactured by dispersing LiMn2O4 powder with a conductive additive and binder in a solvent to form a slurry, which is then coated onto the aluminum substrate, dried, and calendared to ensure a consistent and robust electrode layer. This product is commonly used in battery R&D, educational demonstrations, and performance evaluations for electric tools, e-bikes, and other medium-power applications.

1.       Common Preparation Methods

The preparation of LiMn2O4 (LMO) Single-Side Coated Aluminum Foil begins with the formulation of a slurry composed of LiMn2O4 powder, a conductive carbon additive such as Super P, and a binder like polyvinylidene fluoride (PVDF) dissolved in N-methyl-2-pyrrolidone (NMP). The slurry is mixed thoroughly to achieve uniform dispersion and proper viscosity. This mixture is then evenly coated onto one side of a high-purity aluminum foil using a precise coating method such as doctor blade or slot-die coating. After the coating process, the foil is dried under controlled conditions to evaporate the solvent and solidify the electrode layer. The dried coated foil is then subjected to calendaring, where it is compressed using rollers to achieve the desired thickness, electrode density, and surface uniformity. After calendaring, the material is cut or slit into specific shapes and sizes for laboratory use or further assembly. The final product is inspected for coating adhesion, thickness consistency, and surface integrity to ensure it meets quality standards for lithium-ion battery research and development.
