Secondary storage devices encourage long-term archiving and storing of rarely accessed data in less expensive drives. Devices like compact disks (CDs) and flash drives, which are deemed secondary storage devices, can be used to transfer data from one device to another. Secondary storage devices can be classified into three broad categories.
Electrochemical energy storage (EcES), which includes all types of energy storage in batteries, is the most widespread energy storage system due to its ability to adapt to different capacities and sizes [].An EcES system operates primarily on three major processes: first, an ionization process is carried out, so that the species …
