The Prospective Battery

18 Jun

The first battery was developed by Alessandro Volta in 1800 using alternating layers of metal and blotting paper soaked in salt water. His invention looked very much like a stack of coins, and it provided very slight voltage. However, his formation soon lead to many innovations that have resulted in the modern day battery. We rely on batteries for many functions that we take for granted. They are found in our alarm clocks, watches, cell phones, computers, and cars. How can one forget the specialized batteries of netbooks and notebooks? They have a significant impact on our lives.

Some of the common battery compositions include Lithium Ion – found in many of our consumer electronics including: laptops, digital cameras, and cell phones. These batteries offer good quality charging at temperature extremes making them an appropriate choice for Toshiba, Dell, HP and Lenovo laptop batteries. Nickel cadmium and Nickel metal hydride are used to make many rechargeable batteries. Alkaline based battery is a disposable battery such as Energizer and Duracell, and the lead acid battery is a deep cycle battery found in our automobiles. One of the chief criteria in judging the quality of a battery is its power and energy to weight ratio. While bigger batteries are able to provide more energy, they often do not meet the size requirements in many of our customer electronics.

One of the most hopeful technologies is the fuel cell. Similar to today’s batteries, a fuel cell relies on an electrochemical reaction to produce energy or potential. However, what is unique about it is that it converts hydrogen and oxygen into water to generate electricity. The advantage of the fuel cell, unlike the traditional battery, is that over time a traditional battery will end up losing its power, or you will constantly need to recharge it; while a fuel cell is continuously being recharged due to the flow of chemicals.

Although we may not see fuel cells appear on a broad scale for at least five to ten years, they have very little negative effects. The first applications will be for home and small business use, providing a means for support and supplementary power. Cars will eventually incorporate this technology to help better the environment. Once this technology has proven to be reliable in both of these categories the fuel cell may then make it to large scale power source.

Today, there are companies developing solar and energy storage products, based on nanotechnology using carbon nanotubes. Many deem the ultimate replacement for fossil fuels will be fulfilled by the use of photovoltaic cells, combined with a suitable technology to accumulate hydrogen. The vital energy cycle for future generations will then be using the sun as the primary source of energy, converting it to electricity via photovoltaic methods, using the photovoltaic electricity to electrolyze water, store the hydrogen from the electrolysis process, and use this hydrogen by reconverting it in a fuel cell into electricity. This technology will ultimately result in:

  • Electric field controlled hydrogen storage in carbon nanotubes, i.e. FHSN (Field controlled Hydrogen Storage Nanoparticles)
  • Nickel carbon nanotube batteries, Ni/CN batteries

Batteries play a significant role in our lives and will continue to do so in the foreseeable future. The future of batteries for laptop computers, camcorder, lithium, cordless phone, UPS, alarm systems, watch, hearing aid,still and video camera, digital camera, power tools, cordless drills, and other power supplies, is ever shifting. Technologies such as fuel cells, solar cells, and improvements in the lithium ion battery considerably make our lives easier.

Basic battery technology has not changed much in the past century, but battery chemistries have become more sophisticated. Modern goods are driving a superior need for expediency – which often means wireless and rapidly rechargeable – longer cell life, higher energy density and complete safety and stability of the power source. However, your chief concern in buying a laptop battery as well as batteries for notebooks and netbooks will be to choose the battery that fits your equipment. For this you will have to know the model number of your laptop. It is always recommended to buy battery from the same company as that of your laptop to prevent compatibility issues.
