There’s still confusion among consumers whether batteries are the same as cells. A cell in battery terms is a single containment of everything necessary to store electricity. Whereas a battery is strictly speaking an assembly of more than one of these cells. To add to the confusion there are different types of batteries (which are actually cells).
Let’s Straighten This Confusion Out
Let’s talk about the lowest denominator of batteries, which are individual cells. Assembling these in set for electric vehicles does nothing to change these principles:
1… A Primary Cell has a single life. A factory makes it somewhere, and charges it up. When a user has discharged that cell that’s the end of its useful life, unless someone recycles it. This is not good for the circular economy but the price is lower in a store.
2… A Secondary Cell is a different type of battery from a primary one. That’s because a user can replenish the charge a number of times, using a suitable device. This is a far better solution for the green economy, but the price is higher in a store.
Two Different Types of Secondary Batteries
Secondary, rechargeable cells play a vital role in storing electricity for future use. Typical applications include grid-level storage, and smoothing of electricity from renewable sources. Power utilities use the technology to overcome variable weather conditions. This is our hope for a healthier future.
However, secondary batteries also play a vital role at industrial / commercial level. That’s where they provide back-up power for data centers, hospitals and other real-time activities You would probably not be reading this post but for a secondary battery somewhere. Someday soon we may all drive electric cars.
And finally, rechargeable batteries are everywhere in our private lives too. They power our phones, laptops and mobility devices to mention just a few applications. We live in a world of secondary batteries when we take a good look around us. What would we do without them?
