For the battery industry, quick determination of the ageing behaviour of lithium-ion batteries is important both for the evaluation of existing designs as well as for R&D on future technologies.
Forecasting the lifetime of Li-ion batteries is a critical challenge that limits the integration of battery electric vehicles (BEVs) into the automotive market. Cycle-life performance of Li-ion batteries is intrinsically linked to the fundamental understanding of ageing mechanisms.
(Color figure online) Figure 3 shows how the discharge capacity decreases as a function of the discharge cycle number. In the first discharge cycle, on average, the batteries deliver 92.8% of the nominal capacity (2600 Ah). In the subsequent cycles the discharge capacity slowly drops. The decrease in capacity is more or less linear.
The charging rate of quantum batteries, however, is a superextensive property, as it grows exponentially with size: the charging per unit scales with N, meaning that quantum batteries with larger capacity actually take less time to charge, a counterintuitive and fascinating behavior radically different from that of classical batteries.
These correlations underpin the unique properties of quantum batteries. Quantum batteries are a redesign of energy storage devices from the bottom up. They are modeled with the simplest quantum energy storage system: a collection of identical qubits, which can be sub-atomic particles, atoms or molecules.
The observable ageing effects originate from various chemical and physical mechanisms from the molecular to the macroscopic level. 7, 9, 28 These mechanisms, subsequently called ageing mechanisms, depend on the operating conditions to which the battery is exposed.
