👉 A microbattery is a small battery that can be charged and discharged very quickly, typically at a voltage of less than 1 volt (V). These batteries are commonly used in portable devices such as smartphones, tablets, and e-readers. They are designed to power tiny electronic components like lights, sound effects, or even simple sensors. Microbatteries work by using an electrolyte that is dissolved in water, which allows the voltage to be changed very quickly. This makes them ideal for use
