High-Level Project Summary
Molten salt batteries depends on the process of electrolysis. Its mechanism works when water-salt solution is melted to liquid at a temperature of 150 Celsius to work as an electrolyte. That allows the ions of the two electrodes which are magnesium and nickel to flow though the solution making a chemical energy stored. It also uses a fibber glass separator as the molten salt battery’s stable chemistry not to allow ions to mix together. Then the battery is cooled to the solid state to keep the energy stored inside of it. The battery housing was chosen to be made of copper as it can handle the enormous amount of toxicity of Venus’s atmosphere.

Detailed Project Description
It works as a storage system that stores heat from the high temperature in venus and turns it into energy that provides the space trips, Molten salt batteries depends on the process of electrolysis. Its mechanism works when water-salt solution is melted to liquid at a temperature of 150 Celsius to work as an electrolyte. That allows the ions of the two electrodes which are magnesium and nickel to flow though the solution making a chemical energy stored. It also uses a fibber glass separator as the molten salt battery’s stable chemistry not to allow ions to mix together. Then the battery is cooled to the solid state to keep the energy stored inside of it. The battery housing was chosen to be made of copper as it can handle the enormous amount of toxicity of Venus’s atmosphere and it has been painted with silica to avoid corrosion from carbon dioxide gas , Molten salt battery also has theability to operate and handle temperature to 560 Celsius which is a property that will benefit us in venus planet. Another huge advantage in is that Molten salt batteries have very long life time that can reach 5000 cycles which basically can work for 20 years. It works with a capacity of 25–250 kWh per bank and percentage of efficiency 87, it appeared to be absolutely safe (non-flammable, non-explosive) and requires no additional construction measures (no fire protection, no temperature controversies), It is also much less expensive than a lithium ion battery , it must be able to handle venus' environment for 60 days and more, we choose copper as a material of the container of the molten salt because it would be the ideal material to cover our storage system because it can withstand the planet's high temperature while remaining unaffected by its toxic and harmful gases and painted it with silica that avoid corrosion from carbon dioxide gas.

This resource was crucially helpful as it helped us to know about resources of venus and the missions that we help to explore venus and we used it in finding the resource of the battery as we used the heat in venus as a resource
https://techport.nasa.gov/view/92914
It helped us to know the previous storage systems that had been used to explore venus and it helped us to develop a new and better storage system
Hackathon Journey
It was a great and helpful experience, we learned so much from it and our personalities had been developed, Now we can work in teams and we can develop ideas that could solve a great challenge and now we can make a storage system that provides energy, we chose this challenge because we learned about the problems that face the scientists to explore the planet that will help us to know our past and to find about new resources that we don't know and could help us in our planet, we faced some problems in our project as we didn't find all the information that we needed but we overcame this problem by asking professors in the field and we searched in different places, we'd like to thank the NASA community for their help their help and the resources that we used
