How to release the energy after the device stores it

How do batteries store energy?

Batteries store chemical energy and convert it into electrical energy. However, the standard description of electrochemistry does not explain specifically where or how the energy is stored in a battery.

What does a battery store?

Batteries are valued as devices that store chemical energy and convert it into electrical energy. Unfortunately, the standard description of electrochemistry does not explain specifically where or

How to calculate the energy stored in a capacitor or inductor?

The energy stored in the state of a capacitor or inductor should be calculable by integrating the power absorbed by the device. Suppose we want to know the energy stored in an inductor in a given state.

Can a device store energy if L is a constant?

If L is a constant (which is often dt dt dt true) then v = L di which means vdt = Ldi, which we can substitute dt into the equation for Energy above yielding: which in all likelihood you will have seen before in a physics class. In both of these cases, the device can store energy and therefore its source-like constitutive relation makes some sense.

How does a battery convert chemical energy into electrical energy?

Batteries are valued as devices that store chemical energy and convert it into electrical energy. Unfortunately, the standard description of electrochemistry does not explain specifically where or how the energy is stored in a battery; explanations just in terms of electron transfer are easily shown to be at odds with experimental observations.

What is the increasing demand for batteries due to?

The storage of energy in batteries continues to grow in importance, due to an ever increasing demand for power supplying portable electronic devices and for storage of intermittently produced renewable energy. The analysis provides an explanation of basic electrochemistry that will help students better understand this important topic.
