5 Differences Between the Capacity Lithium Battery and the Power One

APR 20, 2023   Pageview:414

There are several types of batteries available in the world. Each type of battery has its uses and features. Lithium batteries are among the top battery types we use daily. You may not be aware that several types of lithium batteries are available for our use. Capacity lithium and powerful lithium batteries are among the most usable batteries in the world.

You might think that power and capacity lithium batteries are the same because they are both lithium batteries. But you need to correct yourself here because both batteries are comparatively different. 

Suppose you are curious to learn how power lithium batteries and capacity lithium batteries are different. In that case, you must invest your time in this article because it will give you in-depth knowledge about power and capacity lithium batteries.

What is a capacity lithium battery?

Capacity lithium battery is a type of lithium battery you can see everywhere in your life. A capacity type of battery emphasising large or high capacity. High capacity generally applies to higher equipment's high storage, longer life, and storage requirement, like mobile phones, torches, and more.

In short, the main specification of these batteries is large capacity. For example, the capacity of most 18650-capacity batteries on the market is more excellent than 3000mAh, known as a capacity lithium battery.

What is a power lithium battery?

Power-type batteries emphasise the high performance of the battery. These batteries also need a large battery charge and discharging current. 

The main specification of these batteries is to discharge at 10 C or above temperature. These batteries can be charged with a high current voltage. They are most commonly found in electronic cigarettes (vapes), electric vehicles (EVs), drones (UAVs), toy racing cars (RCs), model aeroplanes, and other high-power devices.

What is the difference between battery capacity and battery power?

Power lithium batteries and capacity lithium batteries are generally based on the product and the user's needs. The following are the top specific differences between power lithium batteries and capacity lithium batteries-

1. Discharge Rate

The discharge rate of power lithium batteries is comparatively higher than capacity lithium batteries. The instantaneous of this battery is relatively larger, and may reach up to 30C. At the same time, a capacity lithium battery can only support 1C times the discharge rate.

2. Composition Material

Composition material is also considered the main factor in choosing a battery. The capacity lithium battery has a finer composition material than the power lithium battery. At the same time, the power lithium battery pack consists mainly of positive and negative particles. While the energy density is not high, the use of diaphragm materials and electrolyte conductivity is improved, resulting in higher conductivity. 

3. Voltage Level

When the voltage increases, the corresponding output voltage also increases. Thus power lithium battery types are built to meet the requirement of some high-power equipment. You will be shocked to learn that the direct impact of the parallel connection of this battery is that the current of the overall battery increases, and the voltage remains the same. The capacity is affected by the current of the output; the battery capacity connected in this way is comparatively larger, known as a capacity lithium battery.

4. Uses

Some large pieces of equipment, like electric cars, electronic cigarettes, and starter power, require explosive batteries because the voltage of small power batteries does not have the potential to achieve the need for driving power. Hence, a powerful lithium battery is an ideal solution.

On the other hand, capacity lithium batteries are commonly used in outdoor flashlights, portable power, logo lights, and more because these pieces of equipment are required to maintain long power and slight power discharge. These batteries are like climbing a mountain, and running needs endurance, which requires a high capacity.

5. Current Size

Last but not least, the current size is another crucial factor distinguishing power lithium batteries from capacity lithium batteries. Power lithium battery packs have more lug materials in the positive and negative electrodes than higher-capacity lithium batteries (the goal is to reduce lug resistance and meet higher currents).

What is the capacity of a lithium battery?

Remember, battery capacity measures the charge stored by the battery. However, the battery capacity is typically measured in Amp-hr. The battery capacity emphasises the maximum number of energy that can be removed from the battery under specific conditions. Lithium battery capacity depends on different factors, including density, weight, and more. However, the capacity of the most common negative electrode material in lithium-ion batteries is 372 mAh/g.

Suppose you want to know the exact battery capacity of these batteries; you must multiply the Ah by 0.3 gm. It will help you to find the exact capacity of the lithium battery. 

How is a lithium battery different from other batteries?

Lithium batteries are becoming extremely popular than other batteries, like lead-acid batteries. Many people prefer lithium batteries over other types of batteries. The following are the factors that distinguish lithium batteries from other batteries-

1. Lightweight

The energy density and battery capacity value of these batteries is higher than those of lead-acid batteries. That is why the weight and size of the lithium battery are comparatively less than other batteries at the same capacity. This results in more straightforward operation and installation of lithium batteries.

2. Quick Charging 

Lithium batteries are charged far faster than other batteries. Suppose a lead acid battery took 7 to 8 hours to charge. At the same time, lithium batteries took 2 hours to charge. This is why lithium batteries are installed in electric cars and vehicles.

3. Cycle Life

The cycle life is the number of charges and discharges a battery goes without disturbing a battery's performance. Usually, a lithium battery goes under 5000 cycles, which is relatively more significant than other batteries. At the same time, a battery like lead-acid goes up to 500 cycles.

Conclusion 

Capacity and power lithium batteries are two types of lithium batteries that are entirely different. Power lithium battery is used for equipment that needs more power to operate. On the other hand, capacity lithium batteries are used in equipment that needs large capacity.
