Comprehensive knowledge of high capacity lithium ion battery- concept, FAQs and uses

Do you ever feel tired of charging your devices' batteries now and then? And even after charging their batteries, they still get drained quickly? Or do you want your device to run for longer durations? If so, high capacity lithium ion battery may be what you've needed all along. Check this out: a lithium ion battery with high battery capacity to ensure your battery-powered devices run for longer durations after a single full charge.

You'll get to understand the following by reading this article: what high capacity lithium ion battery is and its  benefits, application scenarios of a high capacity lithium ion battery, how to maintain your high capacity lithium ion battery and so on. Let’s jump right in!

1.What is battery capacity?Which battery has the highest capacity?

Battery capacity is one of the important performance indicators to measure battery performance. It refers to the amount of electricity released by the battery under certain conditions (discharge rate, temperature, termination voltage, etc.), that is, the capacity of the battery. Battery capacity is usually measured in ampere-hours (Ah).

You can also calculate the capacity of your battery using milliampere hours (mAh). 1mAh = 0.001Ah - it is a measure of charge. A battery with the highest capacity has high Ah (or mAh) rating. The higher the Ah rating, the higher the battery capacity. You’re probably thinking to yourself, “What capacity does a lithium ion battery have?”

2.What capacity does a lithium ion battery have?What does high capacity mean with regard to lithium ion batteries?

Lithium batteries usually have a capacity of 2200~ 6500mah. Ternary Li-ion battery cells have a nominal capacity between 2300mAh and 3600mAh. With the rapid development of wearable devices and electric vehicles, the standard of "high capacity" battery is also increasing.

Lithium-ion batteries with lithium metal as the anode have a capacity potential 10 times higher than traditional lithium-ion batteries. Graphite as the anode material of traditional lithium ion battery, storage capacity of 380mAh/g. However, this is much lower than the theoretical capacity of lithium metal 3860mAh/g. Therefore, lithium metal is a more ideal anode material for high capacity batteries.

3.Is higher battery capacity better?

That's not the case, higher battery capacity is not always better. Battery capacity depends entirely on the app, and you can figure out how much battery capacity you need for use. Although higher capacity lithium-ion batteries mean you can give your device a longer life after a single full charge,or say they do away with the constant need for charging devices after short durations, it's vital to buy batteries that are fit to work to prevent unnecessary repairs and power loss.

4.What makes a battery high capacity?How do I increase the capacity of my lithium battery?

You've read that a ternary lithium ion battery cell has a nominal capacity of 2300mAh to 3600mAh. You are probably wondering what makes a high battery capacity. The actual capacity of the battery depends on the number of active substances in the battery and the utilization rate of active substances. The more active substances are, the higher the utilization rate of active substances is, and the greater the capacity of the battery. Conversely, the smaller the capacity.

Lithium-ion batteries have a particularly high capacity because for a given mass, Li has the most particles and can give away the most electrons. You can increase your battery's capacity by connecting your battery cells in parallel. It is worth noting that a parallel battery connection does not increase the battery's voltage. However, all battery cells that are to be connected in parallel must have the same nominal voltage.

A parallel connection works by connecting a negative terminal of one lithium ion battery cell to the adjacent lithium ion battery. The same applies to positive terminals. Doing so increases the capacity by minimizing total resistance.The only major issue that you’ll face is that the size of the battery will increase significantly.

5.What is the application of high capacity lithium ion battery?

Since high capacity lithium ion battery can power devices for longer durations, they are used to power the following:

① Smart robots

Smart robots are artificial intelligent (AI) systems that learn from their environment, build on their capabilities, work alongside human beings and learn their behavior. As such, they need high capacity batteries to power them.

② Wireless communication

High capacity lithium ion battery stores power for wireless communication devices. Examples of wireless communication devices are satellite communication, radar, and Global Positioning System (GPS).

③ Electric vehicles

Electric vehicle manufacturers use high capacity batteries to power their vehicles. These lithium ion electric vehicle batteries can power an electric car for 300 miles, if not long after a single full charge.

④ Backup batteries

High capacity lithium ion battery can back up a house or institution that primarily depends on electric power. Whenever there is a blackout, your high-capacity backup batteries kick in to help you complete your work or watch your movie comfortably.

6.Does high capacity mean high voltage?

No, a high capacity is not the same as a high voltage. As you've read earlier, high capacity batteries enable your battery to run for longer durations. On the other hand, high voltage means that your battery has a higher electric potential difference.

7.How to maintain battery capacity?

Your lithium ion battery capacity can reduce significantly should you fail to handle it well. Here’s how you can maintain your battery’s capacity:

① Limit charging temperature

Lithium-ion batteries are sensitive to temperature. Charging them in extremely low or high temperatures degrades their internal components, compromising the battery's capacity.

② Charge your battery using the recommended charger

Charging your high capacity lithium ion battery using the wrong charger will, of course, damage the battery. It would be best to use the charger recommended by your battery's manufacturer.

③ Follow the battery manufacturer’s instructions

Your high capacity lithium ion battery probably has a set of instructions on how you should handle it. Following the manufacturer’s instructions to the letter may at times seem senseless, but they are indeed highly beneficial. Following the manufacturer’s instructions will help you maintain the battery’s high capacity.

8.How long will a high capacity battery last?

If handled correctly, your high capacity lithium ion battery should last for around 4,000 charging cycles.

9.What is the highest capacity for a rechargeable battery?What is the maximum capacity of a 18650 battery?

The capacity of rechargeable batteries has not yet reached the limit, there are two ways to increase the battery capacity. One is to add special additives, which can greatly increase the capacity of the negative electrode; the other method is to replace the positive and negative materials, and re-pair and combine the positive and negative materials. However, it should be noted that the larger battery capacity does not mean longer cruising range.

Rechargeable batteries often work under the condition of being fully charged, and the capacity will quickly drop below the rated capacity, a phenomenon called memory effect. Like nickel-metal hydride and nickel-cadmium batteries, there is memory, but lithium batteries do not have this phenomenon. No matter what state the battery is in, it can be used at any time without having to discharge it before charging. However, since different battery types vary with regard to capacity, a 18650 rechargeable battery has a maximum capacity of 3600mAh per cell.

10.Conclusion

High capacity lithium ion battery is rechargeable and highly beneficial to the modern world. Capacity refers to the amount of electricity generated in your Li-ion battery due to a chemical reaction. High capacity lithium ion batteries are made by connecting lithium ion battery cells in parallel. These batteries are powerful as they are used to power electric vehicles, wireless communication devices, and smart robots, among other things.

You can take care of your high capacity lithium ion battery by following the manufacturer’s instructions. You can also do that by avoiding charging the battery in extreme temperatures. Finally, always charge your high capacity battery using a recommended charger. Doing so will help you prevent lithium battery capacity loss.
