The Great Old Alkaline Battery
  • All of us know about the great old alkaline battery as assured within the course of our lives is the use of these cells to power any number of devices in and about the house. The alkaline battery was first introduced in the early 60's, as a answer to portability issues inside industrial installations, but of course with the explosion of the portable market and carry all gadgets, these were then introduced to the consumer market in the truck loads and the revolution of energy started from there.

    They come in two types - usually they are either rechargeable or disposable and they are made up of a number of materials that can consist of either zinc, iron and manganese oxide. The chemical make up of the batteries differ greatly from the old zinc chloride batteries, and where they may contain the 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 lower 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 through regular electrical decay. The reason they are known as alkaline batteries is because they have an alkaline within the battery matrix made of potassium hydroxide, which is far various from the acidic electrolyte used in the older zinc chloride and carbon batteries.

    Inside this the negative terminal, or the anode, is made of a material of zinc powder, which gives the aspect of the battery much more surface area and a greater rate of reaction for great electron flow, and it also consists of a positive terminal, or a cathode that is made from manganese. The capacity of the battery is quite regular fare, with 1.5 volts becoming the regular rating that you would get, but simply because of the denser energy storage inside the cells, it can last up to 5 occasions longer than older zinc batteries. 1000mA is the regular current that can be supplied by the alkaline battery, and that increases with size. Higher rated and larger alkaline batteries like the D and C cells, are much larger and have a lot bigger present storage. One thing you should note about the alkaline battery is that over time and misuse, there might be leakage issues.

    This is fairly typical and the leakage of the battery generally is the potassium hydroxide, which when coming into contact with the skin, can trigger issues 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 becoming replaced with the much more expensive and a lot more effective lithium ion battery but we should not neglect the many years that the good old alkaline battery has served the globe of portable gadgets and electronic devices well and will continue to as a inexpensive alternative to the more pricey solutions out there.
