Update on nanoparticle materials

Enable IPC's subsidiary, SolRayo, Inc., is wrapping up its National Science Foundation Phase II grant research on commercializing the application of its nanoparticle solution to lithium-ion battery cathodes. 

The company has had some remarkable results. Applying the nanoparticle solution to lithium-ion battery cathodes decreases the degradation of the cathode materials allowing less expensive cathode materials to be used - previously these materials would degenerate too quickly for efficient use. These materials have particular benefits when used in high temperature or high power applications where the increased stress and degradation would normally be more apparent.

The company is completing tests on full cells with materials currently used in commercial batteries.  Although the program is officially ending, work still continues as SolRayo, together with three other entities, aim to make pouch cells which can be cycled at lower rates. The Company’s goal is to optimize the technology for licensing to larger battery manufacturers (i.e., maximizing the nanoparticles' effect on the companies existing cathode chemistries) as well as provide more standard nanoparticle-enhanced lithium manganese oxide materials to a cathode supplier for resale to other commercial battery manufacturers.

On another note, earlier this year SolRayo submitted a patent application regarding certain aspects of the preparation and deposition of the nanoparticle technology.
