  The idea of ​​the project is simply: The beginning of the challenge problem is how to find a source of energy storage that withstands high temperatures and lasts for a longer period on Venus, so we made a market survey of what exists and searched for the best batteries, and we found a lithium-ion battery and decided to make adjustments to it to suit the new conditions We made changes in both the cathode and the electrolyte where: We Can use sulfur in cathode material instead of Li to increase solubility by grafting polymers to prevent significant solubility of sulfur to the electrolyte .By adding advanced carbon hosts to sulfur cathode on porous carbon, graphene-based composites and carbon nanotubes/carbon nanofibers which have high electronic conductivity and porous framework thus improving active material loading and usability efficiency. However, due to the weak interaction with carbon substrates, LiPS binds very weakly to the cathode structure which leads to the dissolution of LiPS. Hence polar substrates (metal oxides/sulfides/nitrides/senides) are used in the cathode structure. Which helps to increase the interaction with polysulfides.In electrolyte We use Dibutyl ether electrolyte which improves both the performance of the cathode and anode, while providing a high degree of conductivity and interfacial stability.Butyl ether is generally stable to oxidation and reduction and strong acids such as HI and HBr can bind to this ether. And in the presence of oxygen, butyl ether is oxidized to phobic oxide or hydroperoxide, which enables it to get rid of precipitates from the cathode so as not to affect the battery. One of the most common anode materials used today is lithiated graphite, LixC6 , which is composed of graphene sheets intercalated with lithium. New materials such as those based on Silicon and other elemental blends are being researched. Lithiated graphite has a unit cell with a HCP structure. Finally, covering the battery with A special ceramic membrane prevents the electrical cell from igniting., then It will be suitable for the Venus environment and challenge opportunities .

●    Lithium-ion batteries work by using the transfer of lithium ions and electrons from the positive electrode to the negative electrode. At the anode, neutral lithium is oxidized to Li +. These Li+ ions then migrate to the cathode, where they are incorporated into LiCoO2. This results in the reduction of Co(IV) to Co(III) when electrons are received from the reaction of the anode at the cathode. Since lithium is involved in the reactions on both electrodes, the battery can be recharged by running the reactions in the opposite direction.

●     It is used in portable devices such as cell phones, wristwatches, and laptop computers due to its relatively light weight. Another advantage of its light weight is that it can be used in space technologies such as satellites and space probes. Its high energy density makes it suitable for use in all electric vehicles as well as in electrical instruments and medical implants. Lithium-ion batteries are also used to store solar and wind energy. In all these cases, secondary batteries are generally used.,

So that all of this we make changes in it to be more suitable to our situation.

We used it for basic information and take details about Venus and basic information about its environment.

We also used statistics and real pictures of Venus.

 We knew the NASA Hackathon because the event was held at our university, Zewail University, and we assembled the component team. I am Eman, a student in renewable energy engineering, as well as Alaa, while Kholoud is a student in aerospace engineering, and Omar is a student in computer science and artificial intelligence, Cairo University.We chose this important challenge and developed a plan to solve it, as Omar made a market survey showing the existing batteries and their efficiency, so that Alaa would then choose one of them with high protection and put it to work, and then Kholoud put in detail what the challenge requires and what we need to change from Characteristics of the battery and after that I did a research on changing the cathode and electrolyte with a new material to match the current situation and fit the conditions of the planet Venus. And whoever was deaf to put a cover for the battery that would bear the heat and keep the electric battery from igniting, it is made of ceramic faience.. We have benefited from the hackathon in how Thinking and planning the work of the idea through mentors who helped us understand the way to communicate the idea in a good way, and we hope that we have not fallen short and the idea reached.
