FORGE NANO, INC. — Department of Defense SBIR Phase I: N151-048

Description

Performance improvements and cost reduction efforts are perpetually underway to shipboard wireless technology device batteries to meet and exceed the safety, energy and lifecycle targets set forth by the Navy. All-solid-state batteries are being investigated to meet these target metrics as they offer ultimate safety, higher packing efficiency, and longer cycle life of high voltage batteries over state-of-the-art liquid-based batteries. However, all-solid-state batteries have not been widely commercialized on account of low performance resulting from low ionic conductivity of the solid electrolyte (SE), and insufficient cycle life resulting from surface reactions between SE and electrode materials. Surface coatings on battery powders can prevent material dissolution and enable the full potential for all-solid-state batteries including absolute safety under extreme conditions, shelf life and cycle life beyond the life of the instrument they power, high energy density as a result of enabled higher packing efficiency of all-solid-state batteries, and lower cost resulting from improved manufacturing capability. This SBIR Phase I project will focus on applying surface stabilizing coatings to high-impact battery materials for the purpose of creating a complete, high performance all-solid-state battery with a scalable roadmap using existing manufacturing capabilities.
