Akkumulátor

Akkumulátor is a general term for a rechargeable energy storage device. It is a type of electrical battery that can be discharged and recharged by applying an electric current. This ability to be recharged makes it distinct from primary cells, which are designed for single use and must be discarded after their chemical contents are depleted.

The core principle behind an akkumulátor is electrochemistry. Within the akkumulátor, chemical energy is converted into electrical energy during discharge and electrical energy is converted back into chemical energy during charging. This reversible chemical reaction is facilitated by specific materials known as electrodes (anode and cathode) and an electrolyte that allows ions to move between them.

Common types of akkumulátor technologies include lead-acid, nickel-cadmium (NiCd), nickel-metal hydride (NiMH), and lithium-ion (Li-ion). Each type has its own advantages and disadvantages in terms of energy density, lifespan, cost, and safety. Lithium-ion batteries are currently prevalent in portable electronics and electric vehicles due to their high energy density and relatively long cycle life.

Akkumulátor are essential components in a vast array of modern technologies, powering everything from smartphones and laptops to electric cars, grid-scale energy storage systems, and uninterruptible power supplies (UPS). Their widespread adoption is crucial for enabling mobile devices and supporting renewable energy integration.
