SBIR-STTR Award

Quallion LLC’s (Quallion) proposal responds to SBIR Solicitation No. MDA10-034 entitled “Advanced Space Power Technologies”. In our response, Quallion is targeting an electrode development for “beneficial materials development for space-quality lithium rechargeable cells that enable them to accommodate higher energy densities(>200Wh/kg at the battery level); higher charge and discharge rates with suitable voltage characteristics”. Rate capability and energy density are determined by design configuration, and the materials in the battery. Even the inert components like current collectors and separators can contribute to losses in the available capacity and rate capability of the battery. Quallion proposes an electrode design that will reduce the overall internal resistance and increase the mechanical integrity of the electrodes. Phase I will identify an electrode design and process through physical, electrochemical analyses and cell tests. Phase II will further validate the process at a greater scale of manufacturing and large cell testing.

Quallion LLC proposes to continue development of its double-layer electrode technology for lithium ion batteries. The double-layer electrode technology increases adhesion of active materials to improve mechanical strength and the increased surface area increases conductivity. Quallion will refine its electrode design based on lessons learned in Phase I by adjusting the composition of coating materials and the electrode coating process, and incorporating the double-layer electrode into commercial satellite cell designs. Quallion will build prototype cells and perform testing to validate their performance and to generate data for further analysis.
