Dry Cell Construction pdf Free. How to Make a Dry Cell Battery - Lesson 1: Introduction to Batteries, Construction and You This set of lessons will teach you how to make a dry cell battery that uses copper and zinc as the negative and positive electrodes, respectively. We will also give you some safety tips for working with batteries; we attempt to cover every aspect of the construction process in this series. The first lesson is available now, but please check our blog periodically for new posts! The lessons are numbered so that you can jump around if need be, but it does help to take the course from start to finish so that each new post builds upon previous content. If you have any comments or suggestions - please send them to us at lessoninbattery@gmail.com, and we will make sure they get read and addressed! Dry Cell Construction pdf Free. How to Make a Dry Cell Battery - Lesson 2: Making the Rods and Plates The second set of lessons in this series covers making the positive plates and negative rods for your dry cell battery. This is very important because these plates are responsible for storing energy for your battery, so it's important that they be strong enough to do their job! In addition, the negative rods must be big enough to allow electrons from your battery to pass through on their way into your metal grid. If you missed the first set of lessons, go back and check them out, since we've built up a lot of infrastructure for you to draw from! Dry Cell Construction pdf Free. How to Make a Dry Cell Battery - Lesson 3: Making the Grid and Connections For this lesson we will start putting all of our components together and building them into a functioning dry cell battery. This is the fun part; we'll need to make a grid for our plate and rods, solder them together, and insulate it with tape or some other materials. At the same time, we will make connections to your battery's terminals so that it can be plugged into something like a 9V battery power source. We also discuss battery safety with regards to working with batteries; click the link above to check out our article on how bad things can get! Dry Cell Construction pdf Free. How to Make a Dry Cell Battery - Lesson 4: Insulation The final step in our dry cell system is insulating your rods and plates. This keeps them from shorting out on each other and prevents frictional heating, which results in less energy being stored in your battery. It's very important to make sure that there is no contact between the plates and rods when you insulate, otherwise they will become hot and oxidize. By the way, we used cardboard for our insulation in this lesson. It's cheap and easy to find (you can always recycle old boxes or something like that), and it does a pretty good job keeping things insulated. I would never use aluminum foil though; it melts at 275C, and can short your battery out in a heartbeat! Dry Cell Construction pdf Free. eccc085e13
