What is Lithium-ion battery?

These released electrons run from the anode to the cathode. Along the way they power the device in this case a propeller during the charging process the electrons are replaced and return    to the anode.

You would have seen that some devices have lithium? Polymer batteries and some devices have lithium ion batteries but what are the differences?

In these two type of battery technologies?? So to understand about them, let's get started Firstly let's talk about their working, so firstly we  will discuss the working of lithium-ion battery.

 Working of lithium-ion battery

There are primary four components of a lithium ion battery which are : Positive Electrode which    is Connected to battery's positive terminal and the Second is Negative Electrode which is connected to battery's negative terminal.

And the Third is Electrolyte which is between these two terminals and the fourth is Separator which prevents contact between cathode and anode. 

Now the positive electrode is commonly made from alchemical compound called lithium cobalt oxide.

And the negative electrode is made from carbon? 

And the electrolyte used in this type of battery?? Is a lithium salt in an organic solvent. Now you? May be thinking,

 What is the need of Separator??

The need of separator is that it is used to prevent contact between cathode and anode to prevent electric short circuit.

while It allows the transportation of ions which are needed to close the circuit during the passage of current in an electrochemical cell.

Now, when the battery charges up, the lithium cobalt oxide (a positive electrode) gives off some of its lithium ions which move through the electrolyte and hence the battery stores the energy. 

And during discharge these lithium ions go back to the lithium cobalt oxide from carbon and hence the battery provides energy to our device, so it can works.

Now let's move to the working of lithium Polymer battery:

A lithium-ion polymer Battery popularly known as lithium polymer Battery, it is a rechargeable battery that uses lithium-ion technology which uses polymer electrolyte instead of a liquid electrolyte.

Now let's talk about advantages And disadvantages of lithium-ion And lithium polymer batteries. 

Generally both Type of battery have their own pros and cons?. 

So let's firstly go through pros and cons of  lithium-ion battery:

Here, we have pros of lithium-ion battery. The first is : It has very high energy Density due to which it can have high charge Storing capacity in a small size. 

The next is : It has lack of memory effect. 

Let's understand the term Memory  effect. Memory Effect is an effect which causes battery to hold less charge over time. 

we can also say that it is that effect which Makes difficult to charge the battery over time.

Now, let's again come to the pros of lithium Ion battery, the next pros we have got is : It has Cheap cost of production as compared to lithium polymer battery and the last pros we have got  It is a low maintenance battery.

 Earlier, we have Talked about the pros of lithium-ion battery.

Now let's talk about the cons of lithium-ion battery. 

The first is it has gradual self- discharge But this not matters too much for The phones which are always in use.

The next is : These batteries are inherently Unstable and also suffer from aging and are Possibly dangerous, if the barrier which is In between positive and negative electrode. 

Ever gets violated, the chemical reaction can Make combustion. 

The next cons we have got is Their efficiency is decreased with time and the Last cons of lithium-ion battery which we have got is : The lithium-ion battery is fragile and needs A protection circuit to maintain safer operations.

Now let's move to pros and cons of lithium polymer battery. Let's firstly discuss the pros of lithium?? Polymer battery. 

The first is : It is flexible and Have robust design. The next we have got is : It has Lower chance of leaking electrolytes and hence? 

They are a bit safer. The next one we have got is?: It also has a very low self discharge level? And the last we have got is : These batteries??

Are light in weight because of which they? Result in better energy density per kg?

Till now, we were talking about the? pros of lithium polymer battery?.

Now let's talk about the cons of? Lithium polymer battery. The first is?: It has shorter life cycle. The next we have? Got is : These batteries have low energy density?? And hence store less amount of energy than same?sized lithium-ion battery. The next we have got is?: The manufacturing cost of lithium-polymer battery?is also high and the last cons of lithium-polymer battery we have got is : Since their manufacturing?cost is high, so their price is also high. Hope, now you have understood about the working and pros &?cons of lithium-ion battery and lithium- polymer battery.

Lithium battery for solar energy:

lithium-ion batteries in terms of the primary differences a homeowner is going to see in living with a lithium iron phosphate battery as opposed to traditional lead acid is the longevity or the life expectancy of that battery typical homeowner running a solar system depending on how they're sized it originally could expect it within a 10-year window they're going to replace their batteries at least twice more than likely three times. The lithium iron phosphate batteries are warranted for a 10-year performance warranty, so you're not going to have any consideration of changing your batteries for at least 10 years frankly it's more function of total energy throughput however with a 38 megawatt hour total energy throughput the length of the battery is more dependent upon how you're using and how often you're using it, but 10 years would be a excellent example of maintenance-free worry-free energy storage.

Lithium batteries have this sticker shot for people the upfront cost of the original in banking compared to LED is probably going to be four times what the lead acid would be overall cost when you look at them, you know leveled cost of energy storage over a ten-year period the reverse happens for a system like a solar homeowner would have whether living with these batteries and exercising them every day their cost of energy storage over a 10-year period will be likely in the 1/3 to 1/5 of the cost it would be for lettuce and batteries over that same period

of time. Benefit

One of the biggest benefits the lithium as a storage mechanism for residential storage systems is simply the recharge efficiency when you have a lead-acid battery because that's the nature of the chemistry in that battery okay the typical charging algorithm you'd use incorporates a bulk and absorption and then a float stage with a lithium battery you don't have that mechanism it relates to almost entirely bulk charge, and it would go through that stage equivalent to a bulk stage of a for a lead-acid battery for its entire charge cycle what that means because you're avoiding the absorption stage and that is the most time-consuming stage of a lead acid battery bank it means you're going to recharge your batteries in about 1/5 of the time. Existing solar system with an existing array for example could expect that they're going to see between 15 and 30 percent improvement in their overall system performance because they aren't losing that power on just useless exchange of electrons in and out of the battery for an installer or a homeowner

That wants to put in a new system today that basically means that they could size their solar array to be fifteen to thirty percent less than they would otherwise it's fairly compelling when you look at an installation of these batteries and talk about and installer putting these in two volt cells to make a 48 volt system it's 24 batteries in series that's 24 cable connections that they have to be paid you know 200 bucks an hour to install that still has to be serviced that has to be maintained that has to be temperature regulated and any screw-up along the way and that battery is now garbage lithium-ion phosphate batteries protect themselves it's like there's a person inside constantly looking at voltage temperature cycle life you know any of these other things that can be detrimental to the health of a lead acid battery it's taken care of by the processor and the board inside the battery it doesn't work for you, they're completely maintenance-free there's no vent venting no gassing its.

that's purely along the top, there's something I wanted to show you with these 18650 batteries, that I'm not sure that some of you are aware of, and it really in my mind, it needs to be addressed, when you're creating a battery for like an e-bike or what have you. Because of the jarring or the knocking of the batteries against each other and especially as your soldering them that you want to make sure that you're being careful So I just want to let you be aware of something.

What I'm going to do, is I'm going to cut the protective casing off of this one.

So here we have the battery and this instance we have a little, let's zoom out a little..A little plastic cap on top which comes off quite easy. And what i want to do, so that's the positive terminal, this is the negative, but if you. Notice, it's all one sheath, so this is negative as well. I haven't tested it, but only logic says that this is negative. So I'm wondering if this top bit here, is in fact. Positive and this is negative? So What I'm going to do is get my multi-meter. Re-establish the camera, so I've set the meter, now what I'm going to do is touch this part on the body, ok... so that that is negative.NSO now I'm going to touch this edge, this outer rim and the centerpiece.

So as I thought. So this gap here when bridged, will short the battery, so you need to be really careful in the wiring and where the wires rest, because if they're resting on top, and they're laying flat, and they're breaking through the plastic,

what's going to happen is you're going to have a short or a fire.

And if you got this thing between your legs, s you are riding along on your bike, that's not going to be good. So what I have decided to do is to take some extra precaution and cover these in some shrinks wrap tubing, or some heavy-duty tubing, but I think it is just standard heat shrink tubing, but it should give it some nice, much heftier protection than this flimsy stuff. It might even be Mylar, I don't think it's Mylar, it's weird, I'm looking at the viewfinder and doing it all upside down. So yeah, next step is I'm going to show you how to protect these. Here I have some electrical tubing, some protective tubing. I'm going to open this up, pop that down in, and I'm just going to overlap it by about, just over 18th inch. This end as you can see it's pretty long, so what I'm going to do is I'm going to cut this so it's nicely overlapping each side. I'm allowing for a bit of shrinkage, I'm going to center it inside and that should be enough to protect it, and this really is a lot thicker than this, and I would rather have these in my setup as a battery than a bunch of these where they could absolutely, very easily short out.

In taking apart the battery packs the other day I thought, wait a minute. I think the side is also negative. So I want to show you So I want to show you the effect, but I do not want to burn out my battery, so I have just a strand here. i'm just going to touch this across the two. And that is purely along the top. that is ridiculous, so yeah, i am glad I discovered that.
