UV Curable Cathode Binder
- Miltec UV curable binders have been shown applicable to multiple cathode materials and LTO anodes, all with very promising results.
- Cathode samples have been prepared, with excellent results using NMC, LMO, LCO, LFP, NCA, LFP/NCA, LTO
- High-power applications single layer cathodes
- High-energy double and multilayered cathodes
- Proven Manufacturing Consistency
- Under evaluation by OEM’s and cell manufacturers in US, China, Korea, Japan, and Europe
- Developed a UV binder that is NMP-Free allowing for high-speed curing with reduced manufacturing costs.
- UV Curable Gel Polymer Electrolyte – Awarded a US DOD contract to develop pouch cell prototypes for two military battery applications.
- Miltec UV Curing System is installed on a Battery Manufacturer line demonstrating UV technology for Military BB2590, F35 JSF, and 6T batteries.
- Major challenges of capacity, impedance, and long-term cycling have been overcome for cathodes with a UV process.
- UV Process with power batteries has the performance to compete with PVDF-NMP
- UV Multilayer cathode process can be used to produce energy batteries (94-3-3, ~30 mg/cm 2 ).
UV Curable Ceramic Coated Separator
- Developed a UV curable separator ceramic coating with UV Curable binders that achieves excellent resistance to shrinkage and abrasion while maintaining required porosity values.
- UV Ceramic coating for separators shows higher temperature resistance, high adhesion, greater
chemical and oxidation resistance resulting in greater voltage stability.
- Tests show a separator coated on both sides reduced the shrinkage to below 3% after heating to 180°C.
- Developed a printed ceramic pattern process that reduces the weight, allows for higher ion flow (more power) through the coated separator, adds structural strength and does not lead to dendrite growth.
- The Separator UV binder is compatible with a variety of ceramic fillers, including alumina and boehmite powders.
- Coating properties adaptable to different coating methods (i.e., gravure, flexographic).
- Binder chemistry adaptable to meet different performance specifications for porosity and shrinkage resistance.
