An electro-chemical battery uses the materials inside it to release electricity, for us to use in the world beyond. These principles work equally well in the deepest gold mine, and in outer space as far as our astronomers have explored. We provide fascinating insights into our world of batteries in this, and the next few posts. Read on and explore this essential technology.
The Essential Technology in Our World of Batteries
Every battery, or cell comprising it, has a negative anode component, and a positive cathode one. In our deep cycle, gel batteries these are the pairs of lead plates. In the alkaline battery image, the electrodes are the manganese dioxide, and zinc powders.
A controlled chemical reaction takes place between the cathode and the anode when we charge, or discharge a battery. This reaction needs to be regulated to prevent a spontaneous runaway chemical reaction, as reported occasionally in electric scooters with lithium-ion batteries.
That task is the job of the electrolyte separator, which is the sulfuric acid solution in our gel lead-acid batteries. The corresponding feature in the alkaline battery image is a porous separator. Those three components we mentioned must be internally compatible, and able to produce a particular voltage and current. Stay with us, and learn more about our world of batteries.
How and Why Electro-Chemical Batteries Go Flat
Batteries deliver electrical energy to external devices that have similar voltage and current requirements. We should never attempt to mismatch these, because this could damage the battery, and / or the device. However, a particular battery only contains a limited amount of this power. It goes ‘flat’ when this energy is exhausted.
This is the end of the road for single use, ‘primary’ alkaline batteries. At this point they should go for recycling and recovering of their materials. Other batteries, notably our deep cycle, gel lead-acid batteries may recharge many times over. Although they do lose some of their electro-chemical potential every time they do so, until they too are ready for recycling.
