We found that dynamic cycling enhances battery lifetime by up to 38%. Moreover, we determined the window for the tip-over C-rate that balances time-induced ageing and cycling ageing for this commercially relevant chemistry to be approximately between 0.3C and 0.5C, in the range of realistic average C-rates.
Cycling, or the charge–discharge cycle that a battery experiences throughout its lifespan, is one important component. Every cycle alters the composition of a battery physically and chemically, breaking down the electrode materials and forming undesirable compounds that lower the battery performance and capacity .
Cycling degradation in lithium-ion batteries refers to the progressive deterioration in performance that occurs as the battery undergoes repeated charge and discharge cycles during its operational life . With each cycle, various physical and chemical processes contribute to the gradual degradation of the battery components .
To assess the extent of degradation induced by the ageing cycles, we applied standardized diagnostic cycles conducted periodically during the cycling experiments to probe the state of the batteries, as commonly reported in the literature 8, 68, 69, 70.
Over time, the gradual loss of capacity in batteries reduces the system’s ability to store and deliver the expected amount of energy. This capacity loss, coupled with increased internal resistance and voltage fade, leads to decreased energy density and efficiency.
Addressing battery degradation through technological advancements, efficient battery management systems, and improvements in battery chemistry remains crucial to prolonging the lifespan of EV batteries and ensuring the long-term viability and attractiveness of electric vehicles in the transportation sector .

Wireless Battery Life vs. Weight Reduction : r/MouseReview
After watching some mouse weight reduction mod videos, it seems you can drop about 7 grams (>10% of overall weight of many premium mice) by going from a 500mAh battery to a 150mAh battery. My question is, would you like to see companies offer even lighter mice at the expense of shortening the battery life by just using a 150mAh battery to start with? Personally I always …
