Batteries and Chargers

An electric battery is an instrument that consists of several electrochemical cells capable of converting the chemical energy it stores into an electric current.

What types of batteries exist?

There are different types of batteries, among which we can distinguish by their electrochemical characteristics between:

Lithium-Ion (Li-ion) batteries
Lead Acid Batteries
Lithium Polymer (LiPo) Batteries
Nickel-Metal Hydride Batteries
Nickel-Cadmium Batteries (Ni-Cd)
Nickel-Iron (Ni-Fe) Batteries
Fuel cells: This type of battery transforms chemical energy into electrical energy. Part of a fuel (usually hydrogen) and an oxidizer (in many cases oxygen) to produce water, electricity in the form of direct current and heat.
High Capacity Capacitor or Supercapacitor: As an energy and capacity storage element, we find these elements. It is a high capacity capacitor with a much higher capacitance value than other capacitors, but with lower voltage limits.
Batteries or electric cells are elements that transform chemical energy into electrical energy through a transient chemical process. This electrical energy can be accessed through two terminals of the battery, the positive pole and the negative pole.
Supercapacitor (SC), also named Ultracapacitor and Supercaps: As an energy and capacity storage element, we find these elements. It is a high capacity capacitor with a much higher capacitance value than other capacitors, but with lower voltage limits.
Non-Rechargeable Batteries:This electrical energy can be accessed through two terminals of the battery, the positive pole and the negative pole as they are common in the general use.

How can we recharge a battery once its energy is exhausted?

The first thing we have to indicate is that there are batteries that, due to their technology and design, can be recharged, and others that are not rechargeable. Even if we try to recharge a battery that is not prepared for it, the risk of explosion is high.

To restore power to rechargeable batteries, we use a battery charger. It is an instrument used to supply an electric current to a rechargeable cell or a battery to restore its electrical charge.
