An elaborate guidance of lithium ion solar battery- FAQs and uses

In the fast-paced world of endless innovations in tech and widespread digitalization of ways of doing things, energy has been the key to nearly everything. For centuries, the human race has relied upon fossil fuels for all kinds of power. From lighting our homes to powering our cars and other appliances, everything has always been about fossil fuels. But with the recent outcry about climatic change and saving our planet, everybody now realizes the urgent need to change the way we generate our power. And that answer lies with sustainable energy—the solar system in particular, which is the optimal choice for home energy storage.

The solar revolution has been on for decades. Solar power has been and is still providing cutting edge solutions to the energy requirement of people from different continents and races. However, one of its big challenges has been that it is widely received as an intermittent power source. The sun is not shining always. Luckily, the question is now addressed by the new energy storage technologies championed by lithium battery technology. If you want to go completely off the grid, lithium ion solar battery will help you achieve this dream. This battery offers many advantages over regular tubular lead acid battery. However, what is the best solar battery? Which solar batteries last longest? Are lithium-ion solar batteries the best energy storage option?

1.What is a lithium ion solar battery?

To better understand what a lithium ion solar battery is, maybe we should start by understanding what lithium batteries are all about. Lithium-ion batteries are rechargeable batteries with carbonic acid esters organic solvents and LiPF as the electrolyte. The cathode material of Li- ion batteries is mainly lithium cobalt acid, lithium manganese acid, lithium iron phosphate, lithium nickel acid, lithium nickel cobalt manganese acid and other active materials, and the anode active material is usually graphite, lithium titanate or carbon material similar to graphite structure. During charging and discharging, lithium ions are embedded and de-embedded back and forth between the two electrodes. When charging, lithium ions are removed from the cathode and embedded into the anode through the electrolyte, which is in a lithium-rich state, while the opposite is true when discharging.

So back to the question, what is a lithium ion solar battery? Lithium-ion solar batteries are like every other lithium-ion battery, but this time around, they are specially designed to pair with a solar system and store excess solar energy for later use. This rechargeable battery helps maintain a balance between power generation from the solar system and the demand by the consumer. Lithium-ion solar batteries are widely used for home energy storage, such as Powerwall battery, which was first launched in 2015 by Tesla.

The lithium ion solar battery, Powerwall , promoted interest in home energy lithium-ion solar batteries. The success of Powerwall about seven years ago also created hope of making an affordable solar battery technology for residential purposes, building on the lithium ion solar battery technology. Before the first lithium ion solar battery, most solar systems used lead-acid batteries. But with the advent of the more efficient lithium ion solar battery, it is clear that we will be seeing more lithium-ion solar batteries and fewer lead-acid batteries. But then, are lithium-ion solar batteries good for solar panel systems?

2.Is lithium ion battery good for solar?Are lithium ion solar batteries the best energy storage option?

Right after the success of the Powerwall, lithium-ion batteries quickly move to the top of the solar battery food chain. Lithium-ion batteries have more cycles than lead-acid batteries. Lithium-ion battery's ability to save energy makes it a strong battery option for solar systems. They are lightweight, maintenance-free, offer a long lifespan, and low self-discharge.

Whether you plan to use your solar system every day or occasionally, you don't have to worry about your solar battery losing superabundant capacity as it idles away as long as you're using a lithium-ion battery for your solar system. While lithium-ion batteries are more expensive than lead-acid batteries, they are more cost-effective in the long run as they eliminate maintenance costs and have a longer cycle life. If you want to power your home with solar energy 24/7, a lithium-ion battery is your best bet.

There are many solar battery options out there. Still, none comes close to lithium-ion solar batteries when it comes to efficiency. The higher efficiency rating of your lithium-ion battery means that you get to use more of the energy that your solar system produces and stored in the batteries. Lithium-ion batteries can provide you up to 95% efficiency compared to other battery options. However, this is apparently not the only reason lithium-ion solar cells are gaining popularity.

Besides being more efficient than other solar cells, lithium-ion solar cells are smaller and lighter thanks to their high energy density, saving time and effort in installing them. In addition, lithium-ion batteries do not contain heavy metal pollution, so they are far more environmentally friendly than lead-acid batteries.The long cycle life of lithium-ion batteries is also a significant advantage over other batteries. To sum up, the performance of lithium battery in all aspects is obviously better than other batteries, they will be your best energy storage option.

3.Which solar batteries last longest?How long does a lithium ion solar battery last?

Solar batteries are a huge investment you'd be making for your residential energy purposes. If you want to stick with sustainable energy permanently, solar batteries can help you store excess energy, which you can use at night or on cloudy days. However, making the best out of your solar system depends heavily on the solar battery you choose to use. Generally, solar batteries have a lifespan of five to 15 years. However, how long a solar battery will last you depends on: how often you use the battery, the battery environment, the battery type and condition of loading.

One way to determine how long a solar battery will last is to pay attention to its depth of discharge (DOD). Your solar battery's DOD tells you the percentage of its stored energy to use. The higher the battery's DOD, the longer it will last you. However, Using your battery below its common DOD will shorten the lifespan of your solar battery. There are three major types of solar batteries—the lead-acid solar battery, lithium ion solar battery, and saltwater solar battery. These batteries offer different storage capacities and cycle life. Out of the options, lithium-ion batteries last the longest.

The cheaper alternative, the lead-acid battery, they offer fewer cycles and one of the weakest lifespans in solar battery technology. Using such batteries, you can only utilize a portion of the energy stored in the battery. Lead-acid batteries may be a more cost-effective option, but when you consider that their lifespan will force you to change the battery continually, you'll quickly discover that going with the lithium-ion battery is your best bet. Finally, saltwater batteries are relatively new to the solar battery race. This battery technology uses salt instead of corrosive materials in storing and discharging energy. They are much safe and easy to use. Compared to lead-acid batteries, saltwater batteries lasts longer but fall below lithium-ion batteries.

When it comes to solar batteries for home solar systems, lithium-ion batteries are the best. They offer a longer lifespan and more energy. The DOD is the ratio of actual capacity to nominal capacity. Therefore, when purchasing batteries, we should pay attention to the actual DOD of batteries. The DOD of a normal brand new lithium ion battery should be 100%, and when the DOD becomes 80% after long-term use, the battery can be considered as discarded or used in steps.

Therefore, the number of cycles of a cell should be defined as the number of cycles available before DOD drops to 80%. While lead-acid batteries can last you for 5 years, lithium-ion batteries have up to 4,000 cycles when the DOD is 80% and can last for 10 years if charged and discharged on average once a day (4000/365≈10.96). With this battery's long shelf life and high DOD, you don't have to worry about your solar power going off quick.
