Les batteries sont l''élément central qui alimente nos appareils. Au fil du temps, les performances des batteries se détériorent et leur capacité à tenir la charge diminue. Cela s''explique par le fait que la durée de vie de la batterie atteint sa limite. Le cycle de vie de la batterie est donc un paramètre très important.
The most popular alternative today is rechargeable batteries, especially lithium-ion batteries because of their decent cycle life and robust energy density. Their low power density and elevated ESR, which may significantly restrict their capacity to provide power when confronted by large current loads, are their major drawbacks [ 30 ].
