Why does battery generate less terminal voltage difference when current
Some reasons the voltage of a battery goes down under load: Internal resistance. A simplistic first-order model of a battery is a voltage source in series with a resistance. As you draw current, the current causes a voltage across the resistance. That voltage subtracts from the internal voltage source to give you what you get on the terminals.

Why Do Batteries Get Hot?
Batteries generate energy through chemical reactions that happen within them. The electrolyte in the battery reacts with the electrodes, causing a flow of electrons. This flow of electrons generates a current that can be used to power devices. However, these chemical reactions can also generate heat.

6 Frequently Asked Questions about “Why do batteries 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).
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 when a battery is connected to an external circuit?
When the battery is connected to an external circuit, such as a flashlight, the electrons flow from the negative electrode to the positive electrode, producing an electric current. This process is called oxidation-reduction (or redox for short). The chemical reactions inside the battery generate heat, so batteries can get hot during use.
What happens when a battery is used up?
However, a battery only contains a fixed amount of reactants, and, once these have been used up, the chemical reactions stop – the battery is dead! a battery The first ever battery was demonstrated in 1800 by Count Alessandro Volta.
How does a battery store electricity?
The battery's job is to store as much electricity as possible, as fast as possible. It does this through a chemical reaction that shunts lithium ions (lithium atoms that have lost an electron to become positively charged) from one part of the battery to another.
What happens in an electric battery?
This is exactly what happens in an electric battery. When a conducting wire is connected between the positive and negative terminals of a battery, one end of the wire becomes positively charged and the other end negatively charged.
