There is growing interest in lithium ion aircraft batteries for military aircraft as a means to achieve substantial savings in weight and maintenance costs. However, the potential gains of lithium-ion battery technologies are largely limited due to safety hazards associated with the organic liquid electrolytes, which are flammable, volatile and corrosive. There is thus a significant need to develop lithium-ion capabilities without compromising safety for both military and civilian aircraft applications. Through the proposed research, Lionano will seek to develop a solid-state lithium ion battery to provide this capability. Lionano technology has the potential to greatly impact the military aviation sector, as well as the commercial aviation industry, through the development of a safe, light weight lithium-ion battery which increases operating ranges and decreases fuel costs.
Benefit: The proposed all-solid-state battery will eliminate the liquid electrolytes normally used in conventional lithium-ion batteries with a solid electrolyte, allowing the installation of a lithium metal anode that holds far more energy than a conventional graphite anode. Additionally, replacing the flammable electrolyte will eliminate the need for complex and expensive cooling systems in larger batteries, resulting in safer, smaller, and cheaper batteries. This all-solid-state battery will also feature superior capacity, durability, and charging rate, which will satisfy the unmet needs of transformative electrical energy storage applications. Within the global military battery market, the Lithium battery category is expected to have $700 Million revenue in 2016 with 7% growth.
