Electrochemistry

You might know how batteries work, but re-watching that in cool animation, with a video game track playing behind is always a delight. Oh and also, this’ll give you a brief idea about Why even rechargeable die with time. If you wanna go straight to that, skip to 3:07

Types of Batteries

A primary cell is a battery that is designed to be used once and discarded, and not recharged with electricity and reused like a secondary cell (rechargeable battery). The electrochemical reaction in the cell is not reversible, rendering the cell non-rechargeable. In a secondary cell, the reactions can be reversed by an external electrical energy source.

There’s a reason why car batteries can’t run the car itself but start them, the Engineer Guy explains how lead-acid batteries work, and how they compare with other types of batteries. He also explains how batteries are engineered to perform specific power requirements.

Here are some more interesting facts about different types of secondary cells.

Fuel cells

Hydrogen is a versatile fuel that can power almost anything. Fuel cells – an energy conversion device that can harness the power of hydrogen – are key to making it happen.

Here’s some more info about the fuel cell technology.

Lithium Ion

Lithium-ion batteries are used everywhere. From your smartphone to Tesla cars, everything uses Li Ion Batteries (LIBs). They feature high energy density, high discharge power, and long service life. These characteristics facilitated a remarkable advance in portable electronics technology and the spread of information technology devices throughout society. Here is a comparison of different types of lithium ion batteries and more.

However, if you have ordered a phone online, you must have seen a caution notice because the device contain LIBs. Although amazing, Li Ion batteries have a few cons:-

• Lithium ion cells and batteries are not as robust as some other rechargeable technologies. They require protection from being over charged and discharged too far.
• They need to have the current maintained within safe limits.
