Looks like they've cracked the cycling issue to me, halaleuya !

• Achieve control over cross-linking behavior for standard water-based battery binders
• Demonstrate battery slurry processability and electrode coating
• Demonstrate improved electrode coating integrity when submerged in water

In recent development work, AnteoTech has been testing the use of a modified version of AnteoCoat in the production of a Cross Linked Binder for use in Li Ion batteries.

The Cross Linked Binder program is looking to enhance electrode coating cohesion and connectivity by improving on the properties of conventional binders used in the industry. Binders are used to glue the active materials and conductive agent together with the current collector to allow electrons to flow from/to the outside circuit through the active materials–conductive agent–current collector chain.

Binders make up only a small part of the electrode composition, but they play an important role in ensuring the long-term cycling stability and rate capability of electrodes used in Li Ion batteries.

The industry’s focus on the use of silicon in anodes, which expands and contracts during charge and discharge, creates an urgent need for advanced binder systems that are cost-effective and work with current industry processes.

AnteoTech has been working to produce a water-based binder system that will enable low cost industrial scaled usage and create improved electrode cohesion for application in anodes containing active materials such as graphite and silicon.
