Nickel cadmium Dell XPS L501X Battery (Ni - Cd) : it is used in the notebook battery patriarch level character, but because it has serious memory effect and the use of nickel anode materials (Ni) toxic and environment will produce pollution, therefore was soon notebook abandon, instead more excellent nimh batteries. Nimh batteries (Ni - MH) : it and nickel cadmium Dell XPS L501X Battery structure principle basic same, but will cathode with performance better and more environmental nontoxic nickel metal hydride material. Although only a small change, but has brought about great increase in performance. It also has a make nickel cadmium battery the advantages of dust is memory effect is not obvious, so that we need not again for the unpleasant memory effect worry and more convenient to use. Although the performance of ni-mh battery is very good, but with the development of technology it is lighter, energy density higher lithium battery has been replaced, became a laptop batteries in the history of flower yesterday.

Lithium discount Dell XPS L501X Battery: a lot of people think that to lithium battery means we are now commonly used lithium polymer batteries, actually lithium battery including metal lithium ion battery (Li - MO2) and lithium polymer Dell XPS L501X Battery (Li - ion) two. Because Li - MO2 cell in 1989 to enter the market occurs when fire explosion and die young, so it from the line of sight of people soon disappeared, replaced by a more safety of lithium polymer batteries. It is light weight, in the same capacity of the cases it weight only about half of the nimh batteries, so it quickly became a mobile portable equipment of the new favorite, most of the notebook computer use, is now the backbone laptop batteries.

Fuel Cell (Fuel Cell) : Fuel Cell is the notebook Replacement Battery for Dell XPS L501X future star, it has a lot of kinds, including proton exchange membrane Fuel Cell (PEM), alkaline Fuel Cell (AFC) and solid oxide Fuel Cell (SOFC) and so on many kinds of, but because the Fuel Cell start-up time and operation temperature and other reasons in fact for laptop computers use Fuel Cell only proton exchange membrane (PEM) Fuel Cell. PEM fuel cell is the use of fuel methanol, by positive and negative electrode composition it power generation principle is to methanol reforming for hydrogen through after input negative, oxygen input positive, through the role of catalyst, hydrogen atoms into protons and electrons, by different path into positive, electronic through the internal circulation produce electricity, proton through the electrolyte to achieve positive, and oxygen and electronic combination produce water and heat.

Experts agree that restrict the fuel cell commercial application the biggest factor is the fuel cell to use metal platinum (Pt) that platinum catalyst production cost has been in high.At present the production cost of fuel cell in the $500 to $1000 / kw. Research shows that only when the fuel cell production costs fell to $50 / kw level around can truly accepted for consumers. Fuel cell is the major reason for high cost has not been formed batch production, once in mass production stage, the price of fuel cell will certainly greatly reduced.
