Lithium-ion Battery | Is it Really the FUTURE of Automotive Batteries!?!

As we all know humans are more aware than ever about saving the environment. One of the solutions came to our mind is electrifying vehicles especially cars. It is estimated in the future that more than 80% of the car on the road will be electric. But the question is when that future will commence? or should I say it is here with Lithium-ion battery?

Ultium Battery
Electric Vehicle Battery

Everyone is well aware that still the consumers are not convinced by electric vehicles. There are two main reasons for this argument. The first and foremost reason is the range of electric vehicles. Considering the range of their internal combustion engine counterparts they are fairly less range. On the other hand, the time to fully charge the battery for usable kilometers is also in many hours. This is where Lithium-ion batteries come in.

Why Lithium-ion battery?

  • The electric vehicles all across the globe use different types of batteries. Lithium-ion batteries are the most reliable battery having the least charging time with the maximum range possible. Improving the battery, even more, can help reduce the problems that the electric vehicles face.
  • In other words, the Lithium-ion batteries have a fairly high capacity that produces more power as compared to the other car batteries. The capacity of a battery refers to the charge that the battery holds. On the other hand, the performance is the maximum output that the battery can produce in a specific interval of time.
  • Having a large storage density allows the large scale use of the Lithium-ion battery.
  • The density refers to the ratio between the storage capacity of the battery and its weight. For comparison, the density of a battery is measured in Wh/Kg. For instance, a Lithium-ion battery density is about 300 to 500 Wh/Kg which is almost 10 times more than lead-acid battery if not less.

Now let us have look how this works

The Lithium-ion battery is based on the circulation of electrons which leads to a potential difference between the two electrodes or the terminals Positive terminal and Negative terminal. All this rig is immersed in an ionic liquid that is conductive in nature that is it can let the current pass through it.

When the battery is powering a device due to the flow of charge all the electrons are accumulated on the negative terminal or the negative electrode of the battery. A total of the opposite process is followed when charging the battery.

Lithium-ion Battery use

Here are some vehicles across the world currently using Lithium-ion batteries.

Model Battery Charge Times

Is Lithium-ion battery actually the future?

We are still waiting for an even better alternative than the Lithium-ion battery. Research is in progress developing a battery called a solid-state battery. But till then Lithium-ion battery represents the perfect compromise between capacity, volume, and the mass in the electric vehicle sector. It is capable of high voltages, easy recharging, and durability.
