Potential NASA Commercial Applications: NASA is unique to the government in the fact that its mission takes it into a celestial operating environment that is inherently difficult to navigate. This environment is extremely hazardous, contains a variety of reactive oxidants, highly energetic radiation, rapidly moving debris and the like. This places stringent requirements on all components NASA chooses for its missions, and these components govern or limit the extent to which NASA can operate in such an environment. A secondary battery with a net energy density greater than 500 Wh/kg and stable performance past 500 cycles would significantly extend NASA's mission capability. Given design constraints, an energy dense battery would be smaller and allow for the deployment of larger, more complex sensors. More importantly, the use of a strong solid electrolyte would significantly increase the safety of the battery, allowing it to be deployed as a critical component. Should the battery fail, the solid polymer would help prevent damage to other equipment and reduce potential for personal injury. NASA is currently planning on deploying lithium ion batteries onto the ISS to replace its aging nickel-hydrogen cells (Clark 2013). The Hubble telescope also uses nickel-hydrogen cells. Li-ion batteries w/ 500 Wh/kg would increase lifetime, which would result in significant cost savings to due a reduction in space walks. Such a cell would also reduce operational risk when deployed on probes, rovers and the like.
