Phase II SBIR Double Layer Electrode Technology for Advanced Space Power Technologies

Under Phase II of this SBIR, Quallion is continuing 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 is building prototype cells and will perform testing to validate their performance and to generate data for further analysis. Quallion will present initial data which will include rate capability, capacity, and cycle life characterization on test cells.
