6. Fuel (hydrogen) wide variety of sources. Preparation methods varied by oil, methanol reforming hydrogen production, but also by electrolysis of water, bio-hydrogen production and other methods to obtain hydrogen.
7. This fuel cell for Sony np-qm91 added convenience. Liquids such as methanol can be used as fuel, the use of existing petrol filling station system that uses fuel and car fuel in much the same way within a short time to add fuel to add.
8. Environmental adaptability. Its high power density, overload large, may from time to rely on the air, it can amphibious use, to adapt to a variety of environmental and climatic conditions.

Currently, there are five kinds of known types of fuel Nikon en-el4 cells. Its name is in the relevant with adoption of the corresponding electrolyte.

1. Alkaline fuel cell (AFC) using potassium hydroxide solution as electrolyte. This electrolyte was highly efficient (up to 60 1 90%), but affect the purity of impurities, such as carbon dioxide is very sensitive. Hence the need to run in the pure state of hydrogen and oxygen. This limit will be applied to space flight and the international engineering and other fields.
2. Proton exchange membrane fue cell for Fujifilm np-40 (PEMFC) using very thin plastic film as the electrolyte. This electrolyte has a high power-weight ratio and a low operating temperature. Is applicable to fixed and mobile devices an ideal material.

5. Solid oxide fuel cell (SOFC) uses a solid electrolyte (Diamond oxide), the performance very good. They need to adopt the appropriate materials and processes for dealing with technology, because the battery operating temperature is about 1000 ℃.

At present, some research institutions, the ongoing fuel Dell vostro 1500 battery development and research. However, internationally recognized is that in the past decade, PEMFC technology has been developed to a practical stage. However, its process of industrialization has not yet matured. And the need to make further efforts to reduce the cost of this technology.

MP3 player makers early in order to reduce costs, once the use of 7 batteries for Nikon en-el7 as a power supply system, and as players get smaller and smaller, 7 cells had been eliminated, lithium batteries become a standard. The advantages of lithium batteries is self-evident, but it’s life span is limited, once the more frequent use of MP3 players, batteries, the actual use of time is getting short in the end may only persist in less than 30 minutes, MP3 player, hey Do It’s that throwing a fragmentation?

The battery is broken, how to do ?

If in the warranty period, this problem occurs, we suggest that you had better go to after-sales service, in most cases, you can enjoy a free replacement service, if privately inside the battery , Samsung sb-l160 replaced, then the one-year warranty is expired, not worth the candle.

If it is out of the warranty period, you can search through the network the first look at MP3 players in your hands lithium battery models used in what is, in particular the voltage to be consistent. Hot models in general the mainstream, such as Meizu, Apple, Samsung, Onda brands, on-line can directly buy a standard lithium battery alternative, as long as the instructions to meet with theCanon bp-911 battery gift of specialized tools, the machine can be themselves apart hands Quhuan of.

However, some significant part of the MP3 player, use lithium batteries are non-target, then how should we do? In fact, we can go to the local electronics mall to buy the same voltage lithium batteries (at best the same size), different voltage lithium batteries must not be receiving the MP3 player directly to the above. Such as original battery voltage is 1.5V, and the purchase of the battery for Dell gd761 voltage is 3.7V, then they must be connected to the middle of a step-down IC, so as to ensure that the circuit will not be burned.

Note that to extend the maintenance life of lithium battery

We need to stress, MP3 player, use in their daily attention and maintenance. If you buy a new MP3 player, then three times before the charge commonly referred to as an adjustment period, more than 12 hours should be sufficient to ensure the full activation of the lithium-ion activity. Although there is no Samsung sb-l320 battery memory effect, but there are also a strong inert, should be given the full activation can be guaranteed to use to achieve the best performance.

When the environment temperature reaches above 35 ℃, lithium Olympus li-12b battery-powered will not take as long as usual, when the ambient temperature to 4 ℃ below, also appears to reduce the use of time, the situation at this time is best not to charge the battery. To play the greatest performance of lithium batteries often need to use it, so that the electronic lithium battery is always in flux, if you do not often use lithium electricity, should be placed in the shade to reduce the passive reaction speed, and charge in advance, to prevent the battery due to excessive self-discharge, which led to over-discharge, reduced life expectancy, in the conditions permit, the best lithium battery for Nikon en-el8 once a month to “shallow discharge light filling.”
