Cybercab: A Comprehensive Case for the LFP 4680

Battery Performance and Cost

1. 🔋 Tesla's LFP 4680 battery pack could offer 302 miles range for the Cybercab, exceeding the 200-mile goal while potentially being the cheapest, safest, and most durable option in the automotive industry.
2. 💰 LFP 4680 cells have a 70-80% lower cost per kWh per cycle compared to nickel cells, with 4,000 cycles vs. less than 1,500 cycles for nickel cells.

Safety and Environmental Impact

1. 🌿 LFP 4680 cells are inherently cobalt-free, non-toxic, and have fewer public relations issues than nickel batteries, which rely on cobalt for stability.
2. 🛡️ The lower energy density, smaller cells, and higher ratio of inert material in LFP 4680 battery packs could slow fire spread, making them potentially the safest option for the Cybercab.

Manufacturing and Innovation

1. 🏭 Tesla's dry electrode coating process is the cheapest on the market, but its success depends on ramping up the cathode coating process, which is still awaiting updates.
2. 🔬 Tesla's purchase of CATL LFP production equipment and potential development of nickel-doped LFP cells suggest ongoing innovation in LFP technology for improved performance.
