There are so many fresh ideas for batteries from laboratories and universities, it is becoming difficult to keep count. We aim to cover the most significant developments, as we ponder whether we will ever see them on the market. Meanwhile, we all need to keep purchasing batteries for our devices. This article lists the four types of batteries in our stores right now
The Four Types of Batteries Available Today
The four types of batteries that are easy to find include alkaline, nickel-metal-hydride, lithium-ion, and lead-acid chemistries. We describe their applications in the next four paragraphs, so you can make the right purchasing decisions that are also safe.
The First of the Batch: Alkaline Batteries
Alkaline batteries were the first slip-in-your-pocket batteries. They are still extremely popular, because they deliver low-volume electricity for a fair price, for a comparatively long time.
This makes alkaline chemistry an ideal companion for low demand devices like flashlights, clock radios, and key fobs.
The Second Type of Battery: Nickel-Metal Hydride
Nickel batteries don’t hold their charge as long as alkaline ones do, but they deliver more power for more demanding devices. In return for this, they take longer to charge than alkaline ones.
Use nickel batteries for more complex, energy-hungry devices like electric razors, toothbrushes, and others with moving parts.
Are Lithium-Ion Batteries ‘King of the Energy Road’
It certainly seems to be that way, because these batteries charge faster and hold considerably more power. That’s why you find them in electric vehicles and home solar installations.
The tide is steadily turning against them in places like United States Congress. This is because their materials are difficult to recycle, and can catch fire.
Why Still So Many Lead-Acid Batteries?
Lead-acid batteries were the first practical, portable devices for storing electricity, and they still do so reliably and safely. Their technology is elegantly simple compared to lithium-ion, although their density is lower.
Lead-acid batteries are easy to recycle, and their materials can’t catch fire. The U.S. market for these, the last of our four types of batteries, is worth $47 billion. This should grow to $58 billion by 2029.
