Making a battery that can store more energy requires a larger cathode containing more lithium ions. However, the thicker the cathode, the slower the ions will move through it. This reduces the battery's power, leading to sluggish acceleration. PARC wants to evade this trade-off by constructing cathodes from two materials: one dense, and optimised for storage; the other porous, for the speedy transfer of charge.
