Research Institution
This Small Business Innovation Research Phase II project will advance an efficient and lightweight energy storage device for Solar Power Generation Systems by developing a high energy density lithium-air battery with the recharge capability developed in the Phase I. Specifically, the project advances high energy density cells by focusing on increasing the energy density of these cells. Our high-energy air cathodes, with an increased oxygen diffusion rate, are incorporated into the cells. Several areas to optimize the cells have been identified and will be investigated. These cells produce power by the lithium reacting with the air cathode. This significantly decreases the weight by consuming oxygen from the air. Yardneys experience and technologies in oxygen cathodes and powers sources will be adopted in the design of the lithium-air batteries. Advantages of the proposed lithium-air battery include: a safe design, high energy density, a lightweight design, and a high energy density cathode. BENEFIT: The proposed high energy density lithium- air battery has the potential to be used as a lithium-air battery or a lithium-oxygen battery (like a fuel cell). The lithium-air battery could provide energy storage for Solar Power Generation Systems, UAVs, small robots, and aerospace equipment. This technology may also be used to power vehicles on the land, air or sea, and even space. The lithium- air batteries are adaptable to powering electronics. Lithium-air batteries have the potential to replace fuel cells and batteries currently used to power electronic equipment. The strength of the system is its very high energy density. Its lightweight nature and flexible design provide adaptability to many commercial products such as cell phones and computers.
