Different electronic devices have different power requirements. And based on these specific power requirements, different type of batteries are built to suit a specific type of power need.

Just as different types of batteries supply different types of needs of electronic gadgets, there are also different types of technology being used by each of these battery types. They are based on different kinds of chemical principles to produce the power. The elements used for each type of chemical principle are different from one battery type to the next.

Listed below are the most common battery types being used for today’s various electronic gadgets.

NiCd Battery

A NiCd battery is also a type of rechargeable battery. It uses metallic cadmium as negative electrodes. The advantage of NiCd batteries are that they are lighter in weight when compared to their counterparts. It has good charging efficiency and has a small variation in voltage during discharge. They are lower capacity batteries when compared with NiMH batteries. Major area of usage for NiCd batteries are cordless and wireless telephones, emergency lighting, model airplanes, as well as power tools. NiCd batteries are also being used in various electronic devices as well as in electronic toys.

NiMH Battery

A NiMH battery is a type of rechargeable battery that uses hydrogen-absorbing alloy as negative electrodes. These batteries are high capacity batteries if compared to other rechargeable battery types (like NiCd). These batteries are used in all-electric plug-in vehicles, as well as in hybrid vehicles. NiMH technology is used extensively in rechargeable batteries for consumer electronics. Due to their high capacity, long-lasting attribute and easy recharge functions, they are extremely popular among electronic gadgets users.

Li-Ion Battery

This is the most popular and easily identifiable battery type in these gadget-crazy times. One can find these batteries in any or almost every mobile phone being used by people in all parts of the world. A Li-ion battery is a rechargeable battery in which a lithium ion moves between the anode and cathode. During discharge, lithium ion moves from anode to cathode; and from cathode to anode while charging. Due to their high energy efficiency Li-ion batteries are not only being used in electronic devices such as mobile and laptops but also in defense, automotive, and aerospace applications.
