High-Level Project Summary
Venus planet has high pressure and temperature on its surface , so the tasks to Venus has very short durations also the current batteries can't stand the high pressure and temperature on its surface. The battery in this project can operate in Venus and the other planets , where its anode is made of lithium silicide , which gives high energy to the battery , which can power the landers and rovers in Venus surface at more than 60 ๐๐๐ฆ๐ .

Detailed Project Description
The challenge ((Exploring Venus Together)) talks about the inability of the current batteries used in landers and rovers to operate in Venus surface due to:
- High pressure of Venus surface (92 bars).
- High temperature of Venus surface (approximately 452 ยฐC).
that cause failures to the current batteries , which leads to very short durations of missions. The new lithium โ ion (lithium silicide โ lithium cobalt dioxide) battery in the project has high energy density (approximately 38 billion joules per one mole of lithium silicide anode of the battery) because its anode is made of lithium silicide , also it has low discharge rate and self โ discharge rate , also it can withstand the conditions of Venus surface , which gives the opportunity to discover Venus surface at very long durations.
Space Agency Data
We used in our project the data provided by NASA in the ((Exploring Venus Together)) challenge resources. These resources helped and inspired us to doing our project and making the idea. Our team has known the technology and the energy density of lithium โ sulfur battery through the NASA resources , which helped us to make the idea of our project.
Hackathon Journey
At first , the choosing of a challenge related to chemistry was barely hard. However , the challenge ((Exploring Venus Together)) was our choice. Working on the solution of the challenge was challenging because it took much effort to find the idea of the project and making the idea as that we present to you now.
