batéria
Batéria is a term often used in some Slavic languages, including Slovak and Czech, to refer to an accumulator or electric battery. An electric battery is a device that stores chemical energy and converts it into electrical energy through an electrochemical reaction. This electrical energy can then be used to power various electronic devices. The most common type of battery is the galvanic cell, which consists of two or more electrochemical cells. Each cell contains an anode (where oxidation occurs), a cathode (where reduction occurs), and an electrolyte that allows ions to move between the electrodes. Batteries can be primary, meaning they are designed for single use and cannot be recharged, or secondary, which are rechargeable and can be used multiple times. Common examples of rechargeable batteries include lead-acid batteries, nickel-cadmium (NiCd) batteries, nickel-metal hydride (NiMH) batteries, and lithium-ion (Li-ion) batteries. The term "batéria" encompasses all these forms of electrical energy storage.
