Part 3) A lithium ion battery has an energy density of uE = 1.28 × 10° J/m³. To produce a parallel plate capacitor with the same energy density, how large would the plates need to be if the capacitance was equal to the configuration from part 1) and a charge of Q| = 6.43 × 10-ºC was stored on the plate.? A = m Check
