Why Do Crystallized Batteries Experience Capacity Loss?
Crystallized batteries experience capacity loss due to the formation of crystals within the battery that hinder efficient energy transfer. The crystallization typically occurs in lithium-ion batteries, affecting their performance and lifespan.
The U.S. Department of Energy defines capacity loss in batteries as “the reduction in the total amount of charge a battery can store and deliver over time.” This reduction affects the overall utility and efficiency of the battery.
Several underlying causes contribute to capacity loss in crystallized batteries. First, thermal conditions are a significant factor. Elevated temperatures can lead to degradation of the electrolyte and electrode materials. Second, charge cycles impact battery health. Frequent charging and discharging can promote the growth of lithium crystals, a phenomenon known as lithium plating. Lastly, extended periods of inactivity may also induce crystallization, as the battery’s components may settle and harden.
Lithium plating occurs when lithium ions deposit irregularly on the anode instead of integrating into the structure. This can cause a build-up of lithium metal, which decreases the available ions for generating power. Additionally, the electrolyte, which allows ions to move between electrodes, may degrade over time, reducing the battery’s efficiency.
Specific conditions that contribute to capacity loss include high temperatures, which can accelerate chemical reactions within the battery, and inadequate charging habits, such as overcharging or leaving the battery at a low state of charge. For example, consistently charging a battery to 100% or allowing it to discharge completely can lead to increased crystallization. Proper maintenance, including moderate charging practices and storing batteries at optimal temperatures, can help mitigate capacity loss.
