AG13 battery

release time:2024-07-19 Hits:     Popular:AG11 battery

Icebergs in front, sea of fire behind. The core technology of hydrogen fuel cell power AG13 battery is still a flaw!

 

At present, the number of new energy vehicles in the market is not large, but as new energy vehicles enter the road of rapid development, the new energy AG13 battery industry has also developed rapidly. At present, lithium batteries have been deeply recognized by the industry, and solid-state batteries and fuel cells are also expected to have better performance. In the field of power batteries, it can be said that the routes are diversified and promoted simultaneously. So, in the future, will lithium batteries, solid-state batteries, and fuel cells go hand in hand, or will hydrogen fuel cells lead the trend?

 

Is the lack of development of hydrogen fuel cells due to technical flaws?

 

Although fuel cells have received attention, "fuel cells" are still an unsolved mystery. In fact, fuel cells are different from batteries in our conventional concept, because they are not energy storage devices, but power generation devices. From a professional perspective, fuel cells directly convert the chemical energy of fuel into electrical energy; for example, the core of hydrogen fuel cells is a proton exchange membrane (which can only allow protons to pass through). This membrane separates hydrogen into protons and electrons (two H+, which are actually protons, and two e-), and allows them to take two paths. Protons pass through the proton exchange membrane and react with oxygen to form water, and the flowing electrons pass through the circuit to form an electric current, which can drive the motor or enter the AG13 battery for storage; in layman's terms, the final products of fuel cell power generation are only electricity and water.

 

So what limits the development of fuel cells, which are so "environmentally friendly"? The core technology of fuel cells lies in "proton exchange membrane"; and currently, in addition to DuPont in the United States, there is only one company in Japan that can commercially supply proton exchange membrane materials for hydrogen fuel cells (but this company refuses to sell the product to any country). So what are the restrictions besides technical restrictions?

 

As we all know, the power system of fuel cells is the main problem that leads to the increase in the cost of fuel cell vehicles, and the subsequent "charging" is also a major problem. For example, the construction cost of a hydrogen refueling station with a hydrogen refueling capacity of more than 200 kilograms is more than 10 million yuan. Such a high construction cost is obviously the biggest obstacle to the rapid development of hydrogen refueling stations. In addition, under current technical conditions, the catalyst of hydrogen fuel cells is platinum. The global production of platinum is very low and the price is expensive (about twice that of gold).

 

Hydrogen fuel cell technology is a substitute for lithium AG13 battery technology and even the terminator

 

Taking the current gas station operation as an example, the fuel cell charging requires a complete set of energy production and transportation networks as support. For example, the safety issues of hydrogen itself, the safety of hydrogen refueling and the safety issues during operation are not something that can be solved overnight; in layman's terms, the hydrogen storage device of the hydrogen refueling station should meet the requirements of being able to withstand high pressure, having online monitoring functions, automatic alarm in case of danger, and good economic efficiency. However, it is undeniable that the hydrogen fuel cell technology route is a substitute for the lithium AG13 battery technology route and even the terminator.

 

As early as the 1990s, when there were no lithium batteries, hydrogen fuel cell vehicles entered the public eye as a new energy vehicle with great potential; during that period, the future of hydrogen fuel cell vehicles was bright; and before the Beijing Olympics, Beijing opened a fuel cell bus demonstration line (with a single vehicle cost of 30 million yuan), but this fuel cell bus equipped with Mercedes-Benz was only a "flash in the pan". In fact, no one doubts the market prospects of hydrogen fuel cell passenger cars. Compared with other energy sources, hydrogen energy has significant advantages in extraction and application. It can not only be extracted from traditional fossil energy, but also prepared from renewable energy, and has the advantages of high calorific value, clean and pollution-free, and convenient storage and transportation.

 

Looking back, the investment in hydrogen refueling stations is incomparable to that of ordinary gas stations and even charging stations. You should know that the infrastructure of hydrogen refueling stations mainly includes hydrogen compressors, accumulators, refrigerators, etc., and the purchase of these equipment alone currently requires about 25 million yuan; not counting the land price, construction investment and later operation costs. Even if hydrogen fuel will become mainstream in the future, the current technical issues have not made key progress, and there are not many people who need hydrogen fuel at present. Therefore, the author believes that if domestic hydrogen energy wants to get a share of the future AG13 battery market, technology is still the key at present.
