We are in the first episode, the diversification of the future mobile phone charging method for a lot of discussion. We see a big trend, that is, charge the phone system will become more diverse and composite. Will also become more environmentally friendly. However, in many ways the new charge, which can not completely replace the traditional charging method.
In such cases, mobile phones, another group of scientists, in order to address this limitation of power supply in the other direction to forward. That is how to produce more of the battery.
Second, more powerful battery.
In the fantasy future of mobile phone batteries, let us first take a look at some of the traditional mobile phone batteries. Earlier mobile phones used nickel-cadmium batteries, which the traditional “Big Brother” mobile phone on the use of this battery. Later, more environmentally friendly nickel metal hydride batteries emerged. It is more environmentally friendly, because the battery does not contain high cadmium contamination, and that the battery is more compact, more storage capacity. With the technology, lithium ion polymer lithium battery, and subsequently appeared. These batteries lighter than nickel metal hydride batteries, larger capacity. Nickel-metal hydride batteries in particular, it has higher security, and appearance is not as strict size limitations. Now, the pride in lithium battery production costs decreased, and the type of battery capacity and safety of the advantages of convenience, it has the majority share of the mobile phone market. But we can sure, now commonly used in lithium batteries can not meet the growing demand for mobile applications. Scientists can choose to build on existing lithium batteries improve, or to pursue new ways of making batteries for mobile phones in order to make the development of critical help.
Ring Road Battery
Ring road battery is a very interesting attempt, its simply not the hope that the battery capacity, to strengthen the cell phone battery. This new concept is to change the battery the battery charging time to improve the fighting capacity of the battery.
Today, we use the conventional mobile phone batteries, its charging time usually takes a few hours time. And that we are forced to carry a spare battery for mobile phones. When the phone is really no electricity, we would need several hours to ensure the battery charger and power networks remain connected to the battery.
But let us imagine that if the phone battery charge time from several hours to tens of seconds of time? This is not unfounded paranoia. MIT scientists on current lithium battery research shows that the reason can not be charged lithium atoms inside the battery more quickly move, mainly because of iron phosphate lithium ion difficult to pass materials in the nano-channels. Scientists pointed out that if the lithium iron phosphate material on the smear layer could serve as a secondary focus of lithium phosphate transport system, it pushes the ions move through the channel and quickly, then the battery charging rate will be greatly improved. In the ten seconds to complete the charge on the cell phone battery is completely possible. And this is a rapid ion channel in a way which is “Ring Road batteries” the source of the name.
Methanol fuel cell
Fuel cell development has started from the very early, already has about 160 years. It is reported that since 2001, had started in the fuel cell business for mobile terminals research. 2003 STMicroelectronics STMicroelectronics has developed a small portable terminal for mobile phone and other small fuel cell technology. Toshiba in 2004, the development of direct methanol fuel cell (DMFC), a few days ago as “the world’s smallest DMFC” were included into the 2006 edition of “Guinness Book of Record.” Later, the synthesis of East Asia in Japan in January 2006 issued the improved DMFC electrolyte membrane. This technology makes the proton conductivity increased by 1.5 times, continuous operation time was increased from 5000 hours to 7000 hours. At the same time Italy’s Acta
SpA in January 2006 at the 2nd Tokyo International Exhibition on hydrogen fuel cells on display the available ethanol powered fuel cell. Battery without the use of expensive platinum metal raw materials, thus greatly reducing the cost of battery production.
Among the methanol fuel cell technology, scientists generally agreed that only one of the two next most likely be in small electronic devices, commercial applications. They exchange membrane fuel cell (Proton
Exchange Membrane Fuel Cell; PEMFC) and direct methanol fuel cells (Direct Methanol Fuel
Cell; DMFC). They all have small size, light weight, can work at room temperature, and other advantages. However, compared to two years, scientists prefer to direct methanol fuel cell research, because of its higher security and lower production costs.
In the scientists under study so hard, we can finally see some use of the fuel cell test products. Toshiba 2008 in Mobile World Congress
2008, shows a built-in fuel cell phone.

From the thickness, although smaller than the new ultra-thin fashion products, but earlier than the large number of smart phones is entirely acceptable.

Mobile phone top interface can directly add to the fuel cell filled with methanol fuel.

The same phone with a lithium battery. Phone designers call this a “hybrid phone.” Lithium batteries used to charge fuel cells. Scientists pointed out that the application of this hybrid would make the effect of higher battery.

50 ml bottle of 99.5% concentration of methanol fuel cells can be 10-15 times the charge. Each charge can make phone for 6 hours of talk state, if the use of traditional battery only 3-4 hours. But to really practical up, scientists still have to face three problems. First, the battery manufacturing costs need to be better controlled. The second is the situation of self-heating fuel cells also needs to be better controlled. The last is the security, because the home Methanol is a toxic substance.

As the fuel cell by the technology constraints, the use of methanol fuel cell size is often not small. Commercial fuel cell phones now are often used as an external portable cell phone charger set. This is true, this Toshiba made a collection of mobile phone batteries on the experiments, and indeed very special.
And with technology, the volume of methanol fuel cells are also being gradually reduced, the next graph is displayed to the industry this year, SONY, can be placed in her hands methanol fuel cell.

Hydrogen fuel cells
Another branch of fuel cells is hydrogen fuel cells. As the name suggests, this is no longer using methanol fuel cells of this toxic substance, but the use of hydrogen. In this way, the battery will become more environmentally friendly.
Early this year, U.S. scientists in the hydrogen fuel cell technology has made great breakthrough, developed the specifications of only 3 mm of hydrogen fuel cells. This small portable devices such as mobile phones development of great significance. The small size, but the unit storage ability of fuel cells more likely to become mainstream in the future, mobile phone batteries.

The figure this guy is the smallest hydrogen fuel cell, although it can only provide 0.7 volts and 0.1 mA of current, obviously can not drive mobile phones, but scientists believe that with continued efforts to make it one day sooner or later be applied.
Than above this message, MOTO, have suggested a more encouraging. MOTO claimed that Canada Angstrom
Power Company and the MOTO will cooperate in hydrogen fuel cells, through both technology design and production of a MOTOSLVR
L7 mobile phone, using hydrogen fuel cell. The flying time is the traditional cell phone twice. MOTO said there is hope in 2010 for the product and consumers.

Now robust in much of the world’s No. 2 player in hydrogen fuel cells are favorably. They also demonstrated a hydrogen fuel cell powered mobile phones. The product reacts with water and metal to obtain hydrogen as a fuel. Then the response element hydrogen reacts with oxygen to produce electricity. Based on this technology, in theory, the next phone users need only add water, they can charge a mobile phone.
