Different Types of Batteries

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.

Dispose Your Batteries Properly

Battery Disposal Is A Serious Matter

Did you know that if you live in California, it is illegal to dispose of your batteries in your normal everyday trash?

Yes, that is how serious this matter is. Disposing of your batteries is an extremely important matter that various groups are now pushing for stricter laws on disposing matters which can be harmful to the environment.

Millions and millions of batteries are manufactures each and every year. In the United States alone, around 3 billion batteries are sold each year. And with the booming economy of countries such as China, with the corresponding demand for power supplies to power the millions of gadgets being bought by their increasing consumer population, this figure is only expected to grow every year. Batteries run electronic gadgets like laptops, cellphones, flashlights, and numerous electronic toys. And with the growing popularity of everything becoming mobile and wireless, the tendency to provide power to these devices in mobile cells can be expected to increase in use.

Harmful Elements From Batteries

The problem is that some batteries contain metals such as cadmium, mercury, lead and nickel that can seriously damage the environment through contamination if not disposed properly. Incinerating them would not actually solve the disposal problem properly as the ash which becomes the remnant of the burning still contains the metals. And the burning process can also release some harmful elements into the air. Batteries can also explode when it comes into contact with fire or exposed to extreme heat.

Organization To Help You Dispose Your Battery

Thankfully, there are various groups who care enough in helping individuals dispose their batteries properly. Sites like earth911.org can help you locate the nearest recycling and disposal stations in your area. Just enter in your zip code in the website’s interface and you will be provided a list of all the places where you can bring your batteries (and other recyclable material) to be disposed of.

Battery manufacturers also have their own disposal facilities where you can bring your batteries for disposal. Call the phone number printed in the product packaging, or visit the company’s website to know the details. Some cities and municipalities also have their separate depots where you can dispose your batteries. Just give your local government a call to find out.

Buy The Right Kinds Of Batteries

But aside from this, there are other things that people can do to help in preserving the environment and protecting it from the harmful effects of chemicals from these batteries. We can all start by buying the right kinds of batteries in the first place. Buy alkaline batteries which can be disposed together with your other household garbage simply because the chemicals found in alkaline batteries do not pose a threat to the environment. Or better yet, buy rechargeable batteries. They would even prove to be economically wise for you as a battery user since you can use a rechargeable battery over and over just by recharging it.

Technology should help us all move forward without destroying the environment in which we live in. Let us all do our share in protecting our environment. And we can start by doing the simple things like disposing our batteries properly.
