dell laptop battery

A few years ago, including Toshiba and NEC, including a number of Japanese companies claimed that they are available for mobile phones, laptops, Sony VGP-BPS8 Battery and music players use micro fuel cells. This battery must be recharged, just add a little look into the interior of alcohol on the line, and consumers seem to escape the shackles of chargers, batteries era seems to end.

Since it is a silence. Even today, she supported the fuel cell is also difficult to find wrong in the market of it, what is?

Bad branding first cake

In fact, these companies are also the victims. She had not expected a small fuel cell turned out to be a “difficult birth children.”

The researchers found that the battery inside the material too sensitive to temperature and humidity, but also vulnerable to carbon monoxide poisoning. Their creation of the best portable fuel cell performance was only reluctantly, and they claim to replace the lithium batteries, not on the competitive market.

Is being developed currently two main types of fuel cells: proton exchange membrane (PEM DELL Latitude D630 battery ) and solid oxide type. Both can and air along the opposite direction to make the fuel through the layer of special film.

Exchange Membrane PEM coated with a layer of catalyst can, these catalyst of the fuel (usually hydrogen atoms) e away the hydrogen atoms are so positively charged hydrogen ions, which may be through the film, and on the other side connect from the oxygen in the air to water. Is then taken to the charge and hydrogen-ion complex of Rush, the brain, and this process was a continuous current.

to use Indeed, PEM cells from the 60’s had started the last century, it can be at 170 ℃, it is still working to an acceptable temperature. PEM cells, but it is a fatal weakness: it requires pure hydrogen to produce electronics, now no one can see an economically viable way to do this. This forced many developing PEM cell manufacturers have turned to alcohol. In comparison, alcohol is certainly cheap, but it contains low-energy, is a weak source of energy.

The principle of the solid oxide type is exactly the opposite. to penetrate air, oxygen atoms in the other side of the membrane, and was gone electrons with atoms of hydrogen and carbon monoxide can be taken to water and carbon dioxide. Since such a high temperature at 1370 ℃ work, solid oxide batteries once abandoned by the developers. However, it can be used to provide a higher density of hydrocarbons (eg butane) as fuel, and can thus significantly higher than the PEM-cell current. In the liquid, butane is the energy density of 7.4 kWh / l, while the methanol is only 4.4 kWh / L, lithium batteries are usually deliver only able to 0.3 kWh of electricity.

And the end, our best blog here hot batteries:Dell Latitude E6400 battery, Dell Latitude X300 battery ect.
