This is when internal reactions occur within the battery cell even when the electrodes are not connected via the external circuit. This results in the cell losing some of its chemical energy over time. A high self-discharge rate seriously limits the life of the battery—and makes them die during storage.
Electrochemical energy storage devices, such as supercapacitors, are essential contributors to the implementation of renewable, sustainable energy [1].Their high cyclability and fast charge/discharge rates make supercapacitors attractive for consumer electronics, defense, automotive, and aerospace industries [[2], [3], [4], [5]].Many electrode materials, such as …
Capacitive reverse electrodialysis (CRED) is a newly proposed technology to generate electricity from mixing of salt water and fresh water (salinity gradient energy) by using a membrane pile as in reverse electrodialysis (RED) and capacitive electrodes. The salinity difference between salt water and fresh water generates a potential difference over ion selective membranes, which can be …

Richard Pattle was the first who remarked that the combination of river water with seawater can be used as a power source in a ''hydroelectric pile'' (Pattle, 1954, Pattle, 1955a).He stated in 1954: ''The osmotic pressure of sea-water is about 20 atmospheres, so that when a river mixes with sea, free energy equal to that obtainable from a waterfall 680 ft high is lost''.
Addressing global water scarcity by producing fresh water from seawater or wastewater is an urgent priority [1].Capacitive Deionization (CDI) is an electrochemical water treatment technology that removes ions from water via capacitive charging and electrosorption [2], [3] holds great promise for desalination and water purification applications.
