The Great Old Alkaline Battery9904839
All of us know about the great old alkaline battery as guaranteed inside the course of our lives is the use of these cells to power any number of devices in and around the house. The alkaline battery was first introduced in the early 60's, as a answer to portability issues within commercial installations, but of course with the explosion of the portable market and carry all gadgets, these had been then introduced to the customer market in the truck loads and the revolution of energy started from there.
They come in two types - normally they are either rechargeable or disposable and they are made up of a number of materials that can include either zinc, iron and manganese oxide. The chemical make up of the batteries differ greatly from the old zinc chloride batteries, and where they might include the exact same voltage as these batteries, the one advantage that they do have is that the have a a lot larger energy density and the self drain status is much reduce than the zinc chloride counterpart. This indicates that you can maintain your alkaline batteries on the shelf for much longer before it drains all the power away via normal electrical decay. The purpose they are called alkaline batteries is because they have an alkaline inside the battery matrix made of potassium hydroxide, which is far different from the acidic electrolyte used in the older zinc chloride and carbon batteries.
Within this the negative terminal, or the anode, is made of a material of zinc powder, which gives the aspect of the battery much much more surface area and a greater rate of reaction for great electron flow, and it also contains a good terminal, or a cathode that is made from manganese. The capacity of the battery is quite standard fare, with 1.5 volts becoming the normal rating that you would get, but because of the denser energy storage within the cells, it can last up to 5 times longer than older zinc batteries. 1000mA is the regular current that can be supplied by the alkaline battery, and that increases with size. Greater rated and bigger alkaline batteries like the D and C cells, are much bigger and have a lot larger current storage. One factor you should note about the alkaline battery is that over time and misuse, there might be leakage problems.
This is fairly typical and the leakage of the battery generally is the potassium hydroxide, which when coming into contact with the skin, can cause problems and irritations. What ever you do, do not mix battery types and recharge batteries not meant to be recharged - a nicely as storing them properly and maintaining them out of the heat. As of late, the alkaline battery is being replaced with the much more expensive and a lot much more effective lithium ion battery but we should not forget the many years that the good old alkaline battery has served the world of portable gadgets and electronic devices nicely and will continue to as a inexpensive alternative to the much more costly solutions out there.
