Global Nominee
A CHEMICAL REACTION BASED BATTERY CELL FOR VENUS NEXT MISSION LLISSE.
High-Level Project Summary
It is an energy storage system based on a simple but effective chemical reaction which is the future of a next-generation battery system. It is a Lithium/Lithium Carbonate battery. According to Electrochemistry, the Lithium and Carbonate reaction can generate up to 4400Wh of electricity per kg of Lithium. And if it is used for two minutes after every eight hours then it can last up to 3000 hours. But the main thing is Venus has a very harsh and challenging environment as it is the hottest planet in the solar system with 91% higher gravity than Earth. But this Battery can work perfectly at 500-degree Celsius. And the weight is just 2.8kgs and has a volume of 4000 cubic centimeters.

Abstract:
It is an energy storage system based on a simple but effective chemical reaction which is the future of a next-generation battery system. It is a Lithium/Lithium Carbonate battery. According to Electrochemistry, the Lithium and Carbonate reaction can generate up to 4400Wh of electricity per kg of Lithium. And if it is used for two minutes after every eight hours then it can last up to 3000 hours. But the main thing is Venus has a very harsh and challenging environment as it is the hottest planet in the solar system with 91% higher gravity than Earth. But this Battery can work perfectly at 500-degree Celsius. And the weight is just 2.8kgs and has a volume of 4000 cubic centimeters.
Origin of the Problem:
Basically, we dug up the resources and we found out the LLISSE (long lived in situ space exploration) program 2023. And we got the origin of the problem that why we need to design a project that can last for 60 days and how much energy has to be deliver and what would be the size of the proposed solution. This Resource [1] gives us direction towards the solution.
Proposed Battery:
The proposed battery is based on a chemical reaction between lithium reactant and carbon dioxide. As carbon dioxide electrolytically converts into carbonate and carbon monoxide at 90+bars of pressure. And in Venus harsh environment carbon dioxide is abundant just like nitrogen at Earth. So, if we take liquid or you can say molten lithium only in battery container, it will perform the following reactions:
Anode: 2Li 2Li+ + 2e-
Cathode: 2CO2 + 2e- CO3-2 + CO
And Overall, 2Li + 2CO2 Li2CO3 + CO
And this reaction happens in series which gives up to 1.14 volts.
In figure .1, you can see the proposed battery structural idea and the phenomenon of reaction approach.

Note: In the presence of Gold as catalyst this reaction receives a kick start and start giving 1.14V at t=0.
