Hydroxyl-Carbon Coated Lithium Supplement for Moisture-Stable Cathodes

The patent introduces a binder as an intermediary substance during the sintering process. The binder forms a matrix that holds the lithium-containing cores together, preventing them from melting and forming plate-like hardening material. This allows the green body to maintain its shape and be easily demolded while still achieving the desired material density and structure after sintering.

The binder acts as a mediating phase that controls the hardness of the final product. By selecting appropriate binder materials and optimizing their content, the patent achieves a balance where the material has sufficient structural stability from the sintered lithium-containing cores while the binder matrix prevents excessive hardness, making the product easier to process and break when needed.

The patent creates a composite material system where lithium-containing cores are embedded in a binder matrix. The binder serves as a protective phase that isolates the moisture-sensitive lithium-containing cores from environmental moisture and carbon dioxide. This composite structure maintains the high energy density benefits of the lithium-containing cores while significantly improving their stability during storage and handling.

The binder serves as an intermediary coating material that provides both protection and conductivity. Unlike metal oxide coatings that are applied as thin films requiring precise control, the binder forms an integrated matrix during the sintering process, naturally achieving uniform distribution. The binder provides sufficient protection against moisture and carbon dioxide while maintaining good electrical conductivity, eliminating the trade-off between protection and conductivity.
