ECE5340, Spring 2022
Due May 21, 2022
1. Find the amount of Lithium that is required for a Tesla vehicle with 75kWh, battery pack.
If 30% of the world vehicles change to electric vehicle, calculate the amount of Lithium,
Nickel and Cobalt that are needed for the next 10 years.
Assume the following cell chemistry:
C6 / Li[Ni1/3Co1/3Mn1/3]O2 cells.
Search and write about sustainability of Lithium, Nickel and Cobalt for the 30% global
electrification of vehicles and justify your response.
2. Battery design for EV and Bill of Materials
Vehicle Specification:
Design an optimized battery pack for an EV with 250 mile range that consumes 200
Wh/mile. The battery pack output voltage is 200V
Battery Specification:
The battery chemistry is based on Silicon (Si) anode and lithium-rich mixed oxide cathode
(Li[Ni1/3Mn1/3Co1/3]O2). “Si // 4Li[Ni1/3Mn1/3Co1/3]O2”.
 The single cell nominal voltage is 4.0 V.
 The ratio of active material to non-active material in the battery pack is 75%.
1. Calculate the specific energy density of the battery.
2. Design a building block cell with 10 Ah capacity and calculate amounts of anode and
cathode.
3. Design battery pack to meet the vehicle requirements and report battery
configuration.
4. Provide Bill of Materials (BOM) for the anode and cathode of the battery pack.
