Question

A battery produces less electrical energy than the total amount of chemical energy contained in its reactive substances. Which statement correctly explain why the electrical energy produced by a battery is less then expected

Answer 1

Answer:

The energy conversion does not fully occur due to various energy losses.

Explanation:

There are many different types of batteries, but all have three basic components: positive electrode (cathode, or "positive terminal"), negative electrode (anode or "negative terminal"), and electrolyte.

Charging a battery forces ions from  cathode to  anode;  the battery reverses the flow. Over a period of time, this process wears out  cathode, which results in reduced capacity.

Also there can be heat loss inside the system as well which is produced by the conversion from chemical energy.

Hence the chemical energy does not fully convert to electrical energy.
