Battery degradation refers to the gradual loss of a battery's ability to store and deliver energy over time. This process occurs due to various factors such as chemical reactions, temperature extremes, charge/discharge cycles and aging.
Mitigating battery degradation is critical for extending the lifespan of lithium-ion batteries, particularly in EVs and ESS. Here are several strategies to minimize degradation: Maintaining the battery charge between 20% and 80% is one of the most effective ways to prevent overcharging and deep discharging, which accelerate degradation.
Figure 2 outlines the range of causes of degradation in a LIB, which include physical, chemical, mechanical and electrochemical failure modes. The common unifier is the continual loss of lithium (the charge currency of a LIB). 3 The amount of energy stored by the battery in a given weight or volume.
Battery degradation rates vary depending on the type of battery used in energy storage systems (ESS), with the most common types being lithium-ion (Li-ion), lead-acid and flow batteries. These are the most widely used in ESS and typically degrade at a rate of 1–3% per year under standard operating conditions.
As a key factor, the discharge rate has great impacts on both the performance and degradation trend of batteries [1, 4, 5]. However, to our knowledge, the effects of discharge rate on battery capability degradation, especially its quantitative analysis is still an open and challenging problem.
For energy-focused applications, knowledge of degradation will benefit EV owners by reducing warranty costs and minimising degradation performance and range losses over their car's lifetime. Conidence in the state-of-health of the battery will also improve residual values, reducing the total cost of ownership.
