Before its formulation, the success of Sondheimer’s picture of electrons in metals as a degenerate Fermi gas was a mystery2. Even in a simple alkali metal such as Na, the Coulomb interaction between electrons is larger than the Fermi energy. Why wasn’t this a problem for understanding the...
layer capacitances of many Farads a technically feasible option. When two electrodes are inserted into a common electrolyte solution, the respective double layer capacitancesCDL1andCDL2act as two capacitors connected in series. Although according to eq.2the measured capacityCof the capacitor is only...
Secondary batteries still have a limited lifespan, known as the lifecycle. The lifecycle of a secondary battery is based on how many times the battery can be fully recharged until the capacity of the battery drops to below 80% of the original capacity. The rechargeability of a secondary ...
