laenguvõime

Laenguvõime, often translated as "charge capacity" or "loading capacity" in English, refers to the maximum amount of electrical charge a device or material can store. This is a fundamental property in the field of electrochemistry and is particularly relevant for energy storage devices such as batteries and supercapacitors. The unit of measurement for charge capacity is typically the Coulomb (C) or, more commonly in the context of batteries, Ampere-hours (Ah).

The charge capacity is determined by the amount of active material present in the device and the electrochemical reactions that occur during charging and discharging. For a battery, a higher charge capacity means it can store more energy and therefore provide power for a longer duration. This capacity can degrade over time due to various factors, including cycling, temperature, and chemical side reactions.

In supercapacitors, charge is stored through electrostatic processes, and their charge capacity is also a key performance metric. Understanding and maximizing laenguvõime is crucial for developing more efficient and longer-lasting energy storage solutions for a wide range of applications, from portable electronics to electric vehicles and grid-scale energy storage. The concept is distinct from energy density, which relates the stored charge (and thus energy) to the volume or mass of the storage device.
