There are two popular types of batteries readily available to consumers. The first of these are the single-use ones we call primary. Although nowadays we should find second purposes for them through a process we call recycling.
The second type of popular batteries are rechargeable. In other words, we can re-use them by reversing the chemical process that took place when they discharged. However they can’t last forever either, and so eventually we have to recycle them too.
The Most Popular Types of Primary Batteries
There are several different types of primary batteries, depending on their chemistry and the materials inside. The most popular ones are:
- Zinc carbon batteries are the all-purpose industry standard for general use.
- The zinc chloride variety lasts longer, but this advantage comes at a cost.
- Alkaline batteries last even longer but may cost correspondingly more.
- Lithium batteries are even more expensive than that, but are longest lasting.
- Specialist button batteries of various sizes are available in diverse chemistries.
Different Secondary Cells Available On the Market
Secondary battery cells, as we mentioned can recharge. This is a great advantage, although there is an upfront investment. We can purchase some secondary batteries loose in a store. While others are installed inside devices, and may need specialists to replace them. The commonest types of secondary batteries are:
- Nickel cadmium cells, which are the most popular type of battery. Each one may be equivalent to well over 100 alkaline, single-use batteries.
- More durable nickel metal hydride secondary batteries. Their high capacity and low drain makes them suitable for electronic equipment.
- More expensive lithium-ion batteries are lightweight, and even higher in energy density. They are increasingly popular.
- Industry-standard lead acid batteries are the energy source of choice for automobiles, and some energy storage applications.
We discuss recycling primary and secondary batteries in our next post. Don’t be far away. We will back soon.
