Why Do Rechargeable Batteries Fail to Hold Charge Over Time?
Rechargeable batteries fail to hold charge over time primarily due to chemical degradation and the cycling process that occurs during charging and discharging.
According to a study published in the Journal of Power Sources, the capacity fade in rechargeable batteries, such as lithium-ion and nickel-metal hydride, is largely attributed to the breakdown of the electrolyte and electrode materials over repeated charge cycles (Nagaura & Tozawa, 1990). These chemical changes result in increased internal resistance and reduced efficiency in storing electrical energy.
The underlying mechanism involves several factors, including the formation of solid electrolyte interphase (SEI) layers, which can impede ion flow, and the growth of dendrites that can create short circuits within the battery. Additionally, factors like temperature fluctuations and improper charging methods can exacerbate these issues, leading to accelerated aging and diminished capacity. As a result, users may find that their rechargeable batteries hold less charge over time, impacting their performance and usability.
