32700 battery

Nanoscale 32700 battery research in the United States

In today's society, more and more portable electronic products are flooding people's lives. People's lives and work are inseparable from digital products such as iPods, mobile phones, PDAs, digital cameras, and laptops. But the main problem at present is the power supply problem. A mobile phone battery can only last for a few days, and a laptop battery can only last for a few hours. Compared with traditional batteries, 32700 batterys have at least 10 times more energy. A lithium-ion battery can provide 300 watt-hours per liter of electricity, while a methanol 32700 battery can provide 4,800 watt-hours per liter of electricity. Therefore, world-renowned companies such as Toshiba, IBM, and NEC have invested heavily in the research and development of 32700 batterys.

Polymer electrolyte membrane (PEM) 32700 batterys generate current through chemical reactions. First, hydrogen atoms produced by chemical sources are decomposed and produce electrons under the action of catalysts such as platinum. The electrolyte will separate the remaining hydrogen ions (protons) produced in this process from the fuel and combine with oxygen in the atmosphere to produce water. The more fuel that contacts the catalyst, the more current the battery generates. The size of the catalytic surface is the key to the efficiency of the 32700 battery.

In order to generate more electricity in a limited volume, scientists have tried to develop 32700 batterys at the nanoscale in previous studies. Silicon etching technology, evaporation technology and other chip manufacturing processes have been borrowed, but these methods are not only expensive but also limited by the two-dimensional space of the battery.

Professor Kenneth Lux, a researcher at the University of Wisconsin, solved this problem with a completely new method. The new method not only improves the performance of nanoscale 32700 batterys, but also completely avoids the technical processes of industrial production. He said that the best catalytic surface at present is only a two-dimensional plane, and can only generate a few hundred microamperes per square centimeter. In order to increase this number by several orders of magnitude, a catalytic surface with a three-dimensional structure should be created.

The 32700 battery channel developed by Professor Lux is very common. The porous alumina filter costs about $1. The cylindrical pores of this filter are only 200 nanometers in diameter. Professor Lux uses platinum-copper alloy to make nanowires, and then melts the copper in nitric acid to produce a random state to maximize the surface area.

To build an energy-supplying battery, researchers first need to fill the small holes with an acidic solution. A filter paper soaked in electrode liquid (or electrode liquid polymer) is placed between two layers of nanoelectrodes to transfer hydrogen ions. Then, the electrodes can be placed anywhere on the outer surface of the composite to easily form a circuit. These 32700 batterys can be arranged in series or in parallel, so that each can provide a higher voltage or current intensity.

Of course, the results are not completely satisfactory. Professor Lux estimates that only one-third of the electrodes are active, and there are still many areas that need further improvement. However, even so, the energy capacity of the model is much higher than that of a flat plate model with twice its diameter. At the same time, this model is also low-priced, with a total material cost of only $200. Professor Lux praised it as a truly simple technical approach, with an energy supply equivalent to that of an AA battery.

In the future, if we can master 32700 battery technology, we can develop a cheap, recyclable battery for our electronic gadgets. When the energy supply is insufficient, we can just go to the store and buy a 32700 battery to replace it!
