Early electric and hybrid-electric vehicles were frequently powered by nickel-metal hydride (NiMH) batteries. Assume that the discharge reaction for these batteries is given by TiNigH + NIO(OH) TiNi5 + Ni(OH)2, and that the cell voltage is 1.2 V. Nowadays, NiMH batteries have been superseded almost entirely by Li-ion batteries. Assume that the discharge reaction for the latter is given by Lice + CoO2 + Co + LiCoO2, and that the cell voltage is 3.7 V. i. Calculate the specific energy of the two batteries, that is, the energy per kg reactant material, in units of kWh/kg. The molar masses of TiNigH, NIO(OH), Lice and Cooz in units of g mol- are 342.3, 91.7, 79.0 and 60.0, respectively. ii. Use the results obtained in part (b) i. to estimate the distance a car can travel at speed 100 km h - with a NiMH battery Li-ion battery. Assume that either battery contains 100 kg of reactant material and operate at an efficiency of 50 %. Furthermore, assume that a total drag force of 400 N needs to be overcome by the car to travel at a constant speed of 100 km h-1.
