We’re already aware of which are the most popular batteries for solar power system applications. Batteries such as lead-acid and lithium batteries are popular choices for these kinds of applications.
Among these two lithium batteries are considered the better option for their efficiency and power output. But there is a new kind of battery in the market that’s being claimed as the better alternative to lithium batteries. We’re talking about graphene supercapacitor batteries.
Today at Thinpack Power, we’re going to find out all about graphene super capacitor battery for solar power systems. We’re also going to show just how efficient these batteries are over the other options and why you should be using them. Let’s get started right away.
What Are Graphene Supercapacitor Batteries?
To understand what a graphene supercapacitor battery is, we will first need to understand what graphene and supercapacitors are. Once we have a basic understanding it will start to make sense why these batteries are better for a solar power system.
If we’re going by molecular structure, then graphene is an allotrope of carbon. The atoms of graphene are arranged in a hexagonal nanostructure. And since it’s a single layer of atoms, it’s also one of the thinnest materials that exist today.
Thanks to its thin structure, it has some of the best conductive properties ever. And this also allows for better storage of electrostatic charges.
It’s also incredibly lightweight, which makes it perfect for using portable battery packs and supercapacitor batteries.
A supercapacitor is like an upgraded version of a capacitor for storing energy. Instead of using chemical energy, capacitors store electrostatic energy. Supercapacitors just do it much better.
The main working principle behind a capacitor and supercapacitor is pretty much the same. Both make use of conducting metal plates to build up a charge. A separator plate allows the charges to stay away from each other. The flow of the charges from one plate to another is what causes the current to flow.
In a supercapacitor, one of the key differences is that the plates have a much larger surface area. That means the amount of charge that could be stored also increases. Activated charcoal is often used to coat the conducting plates to increase the surface area.
Another key difference from a regular capacitor is the separator. Instead of a thick dielectric layer, a thin insulator is used. The distance between the two plates is also reduced which increases the overall efficiency of energy storage.
How Super Capacitor Battery for Solar Improves Efficiency
We’ve covered the basics of graphene and supercapacitors. A graphene supercapacitor battery combines the best of both worlds and works like a charm. But how do they improve the efficiency of solar power systems? That’s exactly what we’re going to talk about now.
Increased Life Cycle
As we’ve mentioned in the intro, there are several batteries that are popular choices for solar power systems. But all of these work by producing electricity from a chemical cell. That’s one of the major drawbacks of those batteries.
Since those batteries rely on chemical reactions, it also means that they degrade the more they are used. There is a limit to how much electricity you can get from a chemical cell because of this. But that’s not the case for a graphene super capacitor battery for solar power systems.
Supercapacitor batteries rely on electrostatic charge. This is why, theoretically, it’s possible to charge and discharge them without any damage to their lifespan. Sometimes, the batteries will be rated for fixed charging cycles. But even then, they outperform chemical batteries in every possible way.
No Toxic Chemicals
Lead, Acid, Lithium, Cobalt, Manganese. These are some of the common elements that are used to make the electrodes in a traditional battery. Some of these are critical elements, meaning their supply is limited. While others are simply harmful.
But given how a super capacitor battery for solar power systems is made, no such elements are used. This eliminates the toxic waste and use of hazardous elements. Graphene supercapacitor batteries are essentially “cleaner” in that sense.
Small Internal Resistance
In batteries that you’re used to, you will notice that there’s mention of internal resistance in them. What this tells you is basically how much energy will be needed to even start the chemical reaction.
Why is this relevant to you? If your battery has a high amount of internal resistance, you’re basically losing energy every time you use the battery. This is where the inefficiency of the traditional batteries comes from.
How is a super capacitor battery for solar energy system any different then? In a graphene supercapacitor battery, there’s little to no internal resistance. At Thinpack power, we ensure that fact during the manufacturing of these supercapacitor batteries.
Thanks to that, you’re not losing any power from this battery. That’s why a graphene supercapacitor battery is able to perform at 97-98% efficiency.
For a solar power system, efficiency is one of the biggest factors. Now you know, why we’re recommending super capacitor battery for solar power applications.
Works in Low Temperatures
You might be using a graphene supercapacitor battery in an extremely cold climate to power a solar energy system. If that’s the case, you will surely come to appreciate the fact that graphene supercapacitor batteries can operate in extremely low temperatures perfectly.
Take a typical Li-ion battery for example. When charging, the battery can go as low as 0 degrees Celsius. For discharging, it can operate up to -20 degrees. But a graphene super capacitor battery for solar power system can operate at as low as -40 degrees!
This also makes the battery a good choice for cold-weather applications. Next time, you need a battery for cold weather, make sure to put a graphene supercapacitor battery on the list.
Less Costly Maintenance
Another way how a super capacitor battery for solar power systems can improve efficiency is by reducing costs. This combines everything that we’ve been talking about so far.
The improved efficiency, the higher life cycle, and the ability to operate in cold temperatures. All of these means that you need to spend less in order to maintain these batteries.
And if you design a hybrid system with other batteries, the efficiency will improve even more. This will allow the system to run for a longer period of time without maintenance than if you were to use traditional batteries.
And eventually when you have to maintain the battery systems, it will cost you a fraction of what the alternative could be. All the more reason to make the shift to graphene super capacitor battery for solar power systems. Make sure you check out Thinpack to get your hands on graphene supercapacitor batteries.
Some Problems of Using Super Capacitor Battery for Solar
There are some really strong reasons, why you should be using a graphene super capacitor battery for solar power applications. However, there are some drawbacks to it as well. If you’re seriously considering using this battery, you need to be aware of these.
Low Operating Voltage
A trade-off of having high efficiency and a potentially unlimited charging cycle is the low operating voltage. Graphene supercapacitor batteries are not suited for applications where you require a higher voltage.
If you still need higher voltage anyways with these batteries, it’s possible to achieve it by connecting the supercapacitor batteries in series. While it would work as intended, it will increase the internal resistance of the battery and make it less efficient.
Life Cycle Reduction at Higher Voltages
We’ve already mentioned that one of the main benefits of using a graphene super capacitor battery for solar power systems is the higher lifespan of the batteries. But that’s only under ideal conditions. What happens when the conditions are less than ideal?
Typically, a graphene supercapacitor battery will drop down to around 80% efficiency after 10 years of operation. This is still comparatively better than other alternatives.
But if you apply more than the intended voltage for these batteries, it can seriously impact the life cycle. If that were to happen, you would see a decrease in the efficiency of a super capacitor battery for solar in less than 10 years.
If you’ve read everything up until now, it should be clear to you why we’re recommending a graphene super capacitor battery for solar energy systems. The efficiency and performance that this battery can provide over the competition are just the tip of the iceberg.
When you take into account the other factors such as no toxic elements and less cost for efficiency, it starts to make even more sense to use it. Although the cost might seem more upfront, in the long run it evens out thanks to its efficiency.
