5Wh Small Environmental Friendly Hydrogen Battery Comes Out
In recent years, the demand for green renewable energy has been rising, and various innovative energy technologies have also emerged. Among them, the development of fuel cells using hydrogen as a raw material is favored by the industry because emissions do not contain harmful gases such as nitrogen oxides, particulate matter, and carbon dioxide, which serve as green energy sources that can improve environmental pollution and global warming. Compared with the rechargeable battery, the battery can achieve high efficiency and miniaturization, and the future popularity and market prospects are expected. However, although fuel cells using methanol and hydrogen have become widespread, methanol fuel cells are difficult to achieve high power, and although hydrogen fuel cells can realize high power, they are difficult to be miniaturized and difficult to handle. Higher.
With the demand for miniaturization of battery fuel itself and the need for AC/DC converter replacements for rechargeable batteries used in various smart terminals, the development of large-capacity, small-sized hydrogen fuel cells is imminent.
Recently, this area has finally made a breakthrough. At CEATEC 2012 in Japan, Rom demonstrated the hydrogen fuel cell developed jointly with Aquafairy. The two companies use original technology to cure calcium hydride into sheets. Rohm engineers said that sheets with a volume of less than 3 cubic centimeters react with water to generate approximately 4.5 L of hydrogen and 5 Wh of electricity. This type of hydrogen fuel cell is small in size and can operate at room temperature (-5°C to 40°C) and can be used for smart phone charging, batteries such as tablet PCs and PCs, power sources for outdoor and remote areas, and standby power sources in case of disasters. Since water and calcium-based fuels are used in the reaction, the products after the reaction are only water (steam) and there is no harmful gas such as carbon dioxide. After disposal, they can also be treated as general waste. Compared with other batteries in the past, they are An extremely environmentally friendly battery.
There are two kinds of hydrogen fuel cells used to charge smart phones. One is to insert a mobile phone to charge directly through a smart phone case, and the other is to charge a variety of devices through a USB extension cable. Both have a 5Wh The capacity can be filled with a mobile phone for almost 2 hours.
This innovative technology integrates ROHM's power circuit technology, application development technology, and hydrogen fuel cell technology. Next, ROHM, Aquafairy, and Kyoto University will conduct reliability evaluation and further improvement, and strive to enter the practical stage in 2013. In addition, the development of the sheet-type fuel cell is also expected to be used for seismograph power supply and is scheduled to be launched in April next year.
In the future, ROHM will integrate the circuit design, application technology and Aquafairy's fuel cell technology accumulated over many years to continuously promote the development of fuel cells for various applications. In addition, research and development has also received strong support from Professor Hirao Ichihiko of the Graduate School of Engineering, Kyoto University. In the future, the next generation of hydrogen generators and resource utilization systems will be jointly studied. Professor Ping Wei stated that the breakthrough in this technology was mainly to establish a technique for solidifying calcium hydride, one of the calcium compounds, into a small sheet and stably generate hydrogen through water droplets. At the same time, it also has a relatively light and thin integrated battery molding technology. Great breakthrough. He added that now the two companies and Near Meter Systems have started a 400Whr development of small, lightweight batteries. It is expected that the amount of power generation can be greatly increased, and this method will become the mainstream technology for hydrogen fuel cells in the future.
However, there are still some defects in the current products. Hydrogen fuel cells used for smartphone charging are disposable and expensive. Roma said that he hopes that the cost can be reduced to the level of ordinary dry batteries in the future.
The Peristaltic Pump can be used in liposuction surgery, in the process of swelling anesthesia, used to deliver saline.
The definition of swollen anesthesia is to infiltrate into subcutaneous adipose tissue by ultra-low concentration, high-dose, a large-volume local anesthetic (currently used lidocaine) as an anesthetic method for liposuction.
Swelling anesthesia was first proposed by Klein in 1987. It is also called [over-perfusion anesthesia". A large amount of solution containing adrenal and lidocaine is stably perfused into the skin through a peristaltic pump, causing edema and cell tissue gap in the subcutaneous tissue and its structure. The small blood vessels are separated and pressed to be locked, thereby achieving the effects of local anesthesia, pain relief, hemostasis, and tissue separation.
Swollen anesthesia can be used as separate local anesthesia or combined with general anesthesia or regional anesthesia.
The advantage of peristaltic pump in swelling anesthesia:
1, easy operated, non-contamination
2, foot pedal control ,safety & reliability
3, adjustable speed and left/right direction optional
4, Power-down memory function
