The pages below document comparisons between various other battery cell types and the Lithium-ion batteries that was used in the previous car.
The previous Li-ion cell was the Lithium-Nickel-Manganese-Cobalt-Oxide (NMC) type. The 2020 Battery Tech report below documents the specific details of the cell used for MSXIV:
However, we’ll probably find and use newer versions if we choose to run it back with NCM cells, so do some research on modern NCM cell specifications (gravimetric and volumetric density [Wh/kg and Wh/L], charge cycles, capacity, discharge rate, nominal voltage, maximum voltage, cost, etc.), and compare these specs along with general pros/cons (ex. safety, cost, availability) with other battery cell types.
Make sure to keep track of interesting or useful websites you find during your search that can be used as reference later (maybe make a section at the bottom of your page with links used).
If you come across any other battery cell technologies that seem like possible good options for our car, bring them up in the mech-battery-box channel and we’ll see if we can do an investigation into them as well!
After the initial Research, we will move into a mock battery pack design where we design the best possible pack for each battery cell type, based on standard voltage and weight requirements. More details will come on this part soon.
If you have any other questions, feel free to ask them in the mech-battery-box channel, or DM @Owen Li, @Eric Zhao, or @Micah Black on Slack.
