High temperature primary battery for Venus surface missions

Long-Lived In-Situ Solar System Explorer (LLISSE) Potential Contributions to Solar System Exploration

“…to the next decade of Solar System Exploration. T. Kremic 1 and G W. Hunter 1 , 1 NASA Glenn Research Center, 21000 Brookpark Rd., Cleveland, OH 44135 USA, tibor.kremic@nasa.gov, gary.w.hunter@nasa.gov Introduction: Venus, while having similar size, mass, and location in the solar system to Earth, differs from Earth in key ways and holds many scientific mysteries despite the number of missions that have targeted it in the past. Primary known differences from Earth include climate, atmosphere, and perhaps most notably the extreme surface conditions.…”

“…In addition, Venus surface conditions present formidable engineering challenges to landers due to the high temperature, pressure, and reactive chemistry. To date, landed missions have not been able to last more than about 2 hours on the surface, limited in landing site options, and could deploy only one lander per mission [1]. Such short durations have resulted in significant knowledge gaps about the surface conditions of this important body in the solar system.…”

Effect of the supergravity on the formation and cycle life of non-aqueous lithium metal batteries

“…Explaining the formation and evolution of the universe and planets, exploring extraterrestrial life, and establishing permanent human settlements in space are significant reasons why researchers from all over the world are obsessed with outer space 1 , 2 . Complicated service conditions cause various devices (rockets, satellites, and detectors) to be in short-term or long-term special environments, including microgravity and supergravity (Fig.…”

Facile fabrication of graphene-based high-performance microsupercapacitors operating at a high temperature of 150 °C

“… 8 In order to enable the entire device to work at high temperatures, all the components must possess good thermal stability. So far various materials have been developed for different components to increase the operating temperature of conventional (stacked) batteries and supercapacitors, 9 such as molten salts, 10 ceramics, 11 and room-temperature ionic liquids (RTILs) 12,13 for high-temperature electrolytes, clay material for high-temperature separators, 12 and biochar 14 and transition metal sulfides 10 for high-temperature electrodes. However, it is still challenging to integrate the compatible components to fabricate high-performance MSCs in a simple manner.…”
