Memory effect

Memory effect, also known as battery effect, lazy battery effect, or battery memory, is an effect observed in nickel-cadmium rechargeable batteries that causes them to hold less charge. [ 1 ] [ 2 ] It describes the situation in which nickel-cadmium batteries gradually lose their maximum energy capacity if they are repeatedly recharged after being only partially discharged.

Understanding memory effects in Li-ion batteries: evidence of a kinetic

In batteries such as Ni–Cd or Ni–MH the (dis-)charge potential profile is influenced by their history. In other words, these batteries "memorize" the history of (dis-)charge, e.g. depth of charge or discharge in previous cycles, and they behave differently according to that history. 1–3 This effect has critical consequences on the performance of a battery as it
