If you have visited this site before, and we sure hope you have, then you’ll know it’s all about batteries. We also write about global warming because we are concerned and our options are running out. If you are just visiting you’ll find a rich source of new information on these important topics. Today we decided to write an introductory battery module as the basis for everything else you’ll discover here.
The Electrochemical Cell is the Basic Battery Module
A mega battery for an electric car contains thousands of individual cells assembled into connected sets. Some of these are structurally similar to AA batteries. In fact, single batteries are called ‘cells’ in the purest sense, although the store clerk may not know it.
Each individual cell or battery module as the case may be, has two outside connections allowing its electricity to flow. The negative terminal is the source for this, while the circuit completes at the positive one. Meanwhile the ions that provide the energy flow in the opposite direction inside the battery. When they have all made the journey, the battery is flat.
Rechargeable Compared to Primary Battery Cells
Primary cells only work once, because the chemical process inside damages them. It is extremely foolish to attempt to recharge a primary battery module. That’s because it could explode and you might suffer harm.
Secondary, rechargable batteries on the other hand allow multiple replenishment. These send the ions back to where they started so the batteries recharge in a reverse process. You can compare this to a yo-yo if you like. Up and down, and up and down until your wrist times out.
Rechargeable batteries also cannot keep going forever. They lose a few ions during each electrochemical cycle. When their days are over and their energy spent they should go to a recycling point. Those people will know how to recover their materials so they can regenerate as new batteries again.
