What Are Lithium-Ion Batteries and Why Are They So Popular

These are solid-state batteries that use lithium as the primary ion for exchanging charges, hence the name. They are popular due to their high thermal stability, flexible and lightweight design, extended life cycle, and increased safety compared to other battery types.

How Do Lithium-Ion Batteries Work

While lithium-ion batteries come in various shapes and sizes, they all work on the same basic principle. A carbon-covered anode stores the lithium, whereas the cathode is made from lithium oxide doped with cobalt. The electrolyte is usually lithium hexafluorophosphate, which has high ionic conductivity without dissipating too much heat.

During the discharging process, the lithium anode loses electrons, oxidizing into lithium ions and displacing the lithium ions within the electrolyte. The lithium absorbs the electrons within the cathode and reacts with the carbon to form lithium carbide. The oxygen ions react with the cobalt and create cobalt oxide. The reactions are reversed during the charging process.

The Benefits of Using a Lithium-Ion Battery

Lithium-ion batteries have several benefits over other variants that make them suitable for various applications. These include, but are certainly not limited to, the following.

Safety

Being solid-state batteries, lithium-ion doesn’t dissipate too much heat. None of the ions changes its state, so there are no significant thermic reactions. It makes the battery safer than other variants like lead-acid and nickel-cadmium. Moreover, because no highly toxic materials are involved, the repair and disposal of lithium-ion batteries are much safer.

Lifespan

Thanks to high thermal stability and negligible electrolyte loss, lithium-ion batteries can function adequately for a long time. While typical lead-acid batteries have an average lifespan of three years, a Li-ion battery can last well over five years, going over a decade, if kept under strict environmental control.

Resilience

Li-ion batteries are highly durable since they can be sealed tight to resist the harmful elements of their surroundings. Such batteries are waterproof, dustproof, able to withstand severe vibrations, and can survive high-speed impacts against rigid surfaces, provided they have the correct case covers.

Weight

Lithium has a high rate of conductivity, despite being one of the lightest metals on the planet. Therefore, you can build a high-capacity battery that can power a bus without weighing as much as one. The weight-saving measures also augment other features. So, you have a battery fit for highly specialized tasks, like powering a drone or running a mini-cooler on a fishing boat.

Fast-Charging Capabilities

Have you ever seen phone or car advertisements that claim to recharge within surprising timeframes? Chances are, all of them use lithium-ion batteries. Thanks to its solid-electrolyte design, it is swift to divert a high volume of charges to the electrodes. That doesn’t just allow for more high current output but also a level of fast charging that would make any other type of battery explode.

Design Flexibility

Li-ion batteries have no aqueous solutions, making them suitable for a wide range of designs. You can manufacture the battery as cylinders, sheets, boxes, or any other frame without worrying about leakage or stress points.

5 Best Lithium-Ion Batteries on the Market Today

While you can get lithium-ion batteries from most major battery manufacturers available in your area, some stand out for their performance and value. Here are a few of them that retain the top spot for their respective fields.

Samsung AA Li-ion Batteries

How To Choose the Right Lithium-Ion Battery for Your Needs

When choosing the correct lithium battery, you must consider a few factors.

Environmental Conditions

Lithium-ion batteries are highly susceptible to changes in temperature. It can’t operate efficiently in temperatures below 12°C (53.6°F) and above 40°C (104°F). Thus, if you encounter such temperatures, it is best to choose a battery with good insulation.

Current Density

Lithium-ion batteries have high thermal stability, but they still have limits to the maximum current output. If you desire high current density, then you should go with lithium-iron-phosphate variants. For improved voltage capacity, lithium hexafluorophosphate is best used as an electrolyte.

Source of Electricity

The source of electricity that you use to recharge determines which battery suits you best. If you charge with high-density sources like power grids or solar energy, you should prefer high-capacity batteries, preferably ones with more than 200 Ah.

Ease of Replacement

Depending on which manufacturer supplies your lithium-ion batteries, your battery may have a different lifecycle. Some offer a 3-year warranty while others offer more than five. You should choose the one depending on how easy it is to replace the battery. Keep in mind that a more extended lifespan usually means higher costs.

Tips for Taking Care of Your Lithium-Ion Battery

You can make your battery last much longer than its rated lifespan through a few simple steps.

Keep the battery in an isolated chamber and at a consistent temperature.
Check the terminal voltage using a multimeter every few months.
Clean the terminals with a mild solvent if you spot any dirt or rust.
If the seal of the battery is light, keep the surface tidy by cleaning it with a soft cloth.
