Let’s assume that a first-generation Tesla Powerwall is made up of battery cells that use graphite (C6) in the anode and lithium cobalt oxide (LiCoO2 ) in the cathode. Assume each cell’s capacity is 2.7 Ah and has a voltage of 4.4 V. If the Powerwall’s total storage capacity is 7.00 kWh, how many cells are there? What is the total mass of anode (kg) and cathode (kg) material in the Powerwall? Assume that the energy content of 1 gram of graphite is 370 mAh/g, and the energy content of 1 gram of LiCoO2 is 137 mAh/g
