Super-Conducting Electron Storage Packs for the Moon and Mars?

With superconductors practical at very low temperatures, I have wondered if N.A.S.A. has developed super-conductor storage 'batteries' for small space-craft. A variety of super-conductor 'battery' storage packs could be launched into space and made available for storing solar power and perhaps partly charge small ion engines.

Hundreds of super-conductor electron storage units might be deposited on the moon in various locations for electrical needs of astronauts and other. Although Mars is warmer than the moon, it might be worth studying the concept of landing super-conductor storage units there too in order that various space-craft roving on the surface could be recharged readily. Suoer-conducting technology would of course be useful on Alaska's North Slope and the rest of the Earth.

The moon would be a very good place for creating networks of super-conducting wire grids for surface transportation power. Solar panels of a thin film might be laid out nearby to input electrons to the super-conductor.

Has a study been done on thee maximum density of superconducting storage of electrons? What about the lightest weight for super-conducting materials? Can superconducting materials be designed integrated with thin film solar voltaic capture?

With the recent publication of the discovery of a substantial amount of ice in at least 42 craters on the moon-some as much as six feet in depth, it is disturbing mildly, to recall that some would exploit that rare resource for rocket fuel. Such valuable ice-water should be for drinking and growing plants within a 100% recycling containment context. Such profligacy with resources is remarkable yet consistent wit federal non-renewable macro-economic policy.
