6 FAQs about [How does a double-liquid battery generate current]
How does a battery produce electricity?
“The ions transport current through the electrolyte while the electrons flow in the external circuit, and that’s what generates an electric current.” If the battery is disposable, it will produce electricity until it runs out of reactants (same chemical potential on both electrodes).
How do lithium ion batteries work?
When you unplug the power and use your laptop or phone, the battery switches into reverse: the ions move the opposite way and the battery gradually loses its charge. Read more in our main article on how lithium-ion batteries work.
What happens when a battery is wired up in a circuit?
When the battery is wired up in a circuit, an electrochemical reaction takes place. Positively charged ions move from one electrode to the other through the electrolyte. Negatively charged electrons flow from one electrode, out of the battery, out through the circuit, and back to the other electrode.
What happens when a battery reacts with an electrolyte?
Whatever chemical reactions take place, the general principle of electrons going around the outer circuit, and ions reacting with the electrolyte (moving into it or out of it), applies to all batteries. As a battery generates power, the chemicals inside it are gradually converted into different chemicals.
What is a battery & how does it work?
“A battery is a device that is able to store electrical energy in the form of chemical energy, and convert that energy into electricity,” says Antoine Allanore, a postdoctoral associate at MIT’s Department of Materials Science and Engineering.
What happens if a battery runs out of reactants?
If the battery is disposable, it will produce electricity until it runs out of reactants (same chemical potential on both electrodes). These batteries only work in one direction, transforming chemical energy to electrical energy. But in other types of batteries, the reaction can be reversed.
