The Battery

There are many different types of batteries and vehicles, but the main one, the most efficient one, is lithium-ion. These batteries have 4 main components: a positive electrode, a negative electrode, a separator, and an electrolyte.  All batteries are generally similar in the way they work. When charging, the lithium ions from the positive electrode move through the electrolyte over to the negative electrode. It is here that the lithium ions stay until the battery is turned on and power is needed to power the car. Once the car is turned on, the lithium ions start moving back through the electrolyte from the negative electrode to the positive electrode. It is this process that creates energy which powers the battery for the car, thus powering the engine, which then in turn makes the car move. If the car is turned off, then the ions will cease to flow through the electrolyte at such a high rate that is necessary to power the car (some discharging will still occur, just at a much slower rate). Similarly, if the lithium ions all move over to the positive electrode side of the cell, and there are no more ions moving through the electrolyte, the battery will have no power and the car will shut off.


Advantages

Electric car batteries have many clear advantages over normal car batteries. First of all, they don't use gas. It is estimated that electric car owners can save more than $1,500 annually of gas money. Additionally, electric cars have a very efficient way of storing and retaining their energy whilst driving. The battery will shut off when the car is stopped in order to save power, and while braking, the battery will actually recharge itself. This is called regenerative braking. Finally, the average driving range of BEVs on a single charge in this day and age is somewhere around 80-100 miles, which is more than enough for the majority of driver's daily use. However, car manufacturers are attempting to develop batteries that can power cars for around 200 miles on a single charge, or even all the way up to 265 miles without dying. 


Disadvantages

However many advantages there are for electric batteries, there are also disadvantages that have not been solved quite yet. First of all, the batteries potentially do not create zero emissions. They create zero exhaust emissions, and this is what most of the population believes to be the only emissions that matter, but the batteries also could produce heat-trapping gases in its manufacturing. And there is also the amount of pollution created during the extraction of fossil fuels in order to create the battery in the first place. So maybe these batteries aren't as clean as we may think. Additionally, these batteries are decently expensive to make. The Chevy Volt had a 16 kWh pack, and the battery pack cost about $500-$600 per kWh, so that would be around a minimum of $8,000 to manufacture. So it is not the cheapest way to make a car battery, but the goal is to have the number down to around $250 per kWh by 2020. And finally, we have the disposal of the batteries when they finally die, which is an issue in its own that we are still trying to figure out a safe way to do so.


Conclusion

Currently, electric batteries are not the most popular choice for a battery nor are they anywhere near being the most common used in cars on the road. However, as they continue to get more efficient, cheaper, and easier to dispose of, they can become the most common car battery in our world. It is just a matter of time before it happens, as being environmentally friendly becomes more popular and necessary.
