CR2032 button cell

How can hydrogen CR2032 button cell break through the core technology?

In recent years, new energy vehicles have become a hot topic in the automotive industry, and major automobile manufacturers are developing new energy vehicles. Although the number of new energy vehicles in the market is not very large, as new energy vehicles are favored by policies, the new energy battery industry has also received focus. For example, lithium batteries are highly concerned by the industry, and solid-state batteries and CR2032 button 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 CR2032 button cells go hand in hand, or will hydrogen CR2032 button cells lead the trend?

Hydrogen CR2032 button cell technology is a substitute for lithium battery technology

Taking the operation of gas stations today as an example, a complete set of energy production and transportation networks are needed to support the charging of CR2032 button cells. For example, the safety issues of hydrogen itself, the safety of hydrogen fuel filling, and the safety issues during operation are not something that can be solved overnight; in layman's terms, the hydrogen storage device of a hydrogen 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.

As early as the 1990s, when there were no lithium batteries, hydrogen CR2032 button cell vehicles entered the public eye as a new energy vehicle with great potential; during that period, the future of hydrogen CR2032 button cell vehicles was bright, but for a period of time afterwards, hydrogen CR2032 button cells were far from ideal development. In fact, no one doubts the market prospects of hydrogen CR2032 button cell passenger cars. Compared with other energy sources, hydrogen energy has significant advantages in extraction and application. It can not only be extracted through traditional fossil energy, but also prepared through renewable energy, and has the advantages of high calorific value, clean and pollution-free, and convenient storage and transportation.

Why has hydrogen CR2032 button cell not been developed?

CR2032 button cells are different from batteries in our conventional concept, because they are not energy storage devices, but power generation devices. From a professional perspective, CR2032 button cells convert the chemical energy of fuel directly into electrical energy; for example, the core of hydrogen CR2032 button cells is a proton exchange membrane (which can only allow protons to pass through). This membrane separates hydrogen into protons and electrons (two protons H+ and two electrons 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 battery for storage; in layman's terms, the final products of CR2032 button cell power generation are only electricity and water.

Since CR2032 button cells are so "environmentally friendly", what limits their development? The core technology of CR2032 button 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 CR2032 button cells in the world, but this company refuses to sell the product to any country, which has hindered the development of CR2032 button cells.

As we all know, the power system of CR2032 button cells is the main reason for the increase in the cost of CR2032 button cell vehicles, and the subsequent "charging" is also a major problem. 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 high construction costs are obviously the biggest obstacle to the rapid development of hydrogen refueling stations. In addition, the catalyst of hydrogen CR2032 button cells is platinum; you should know that platinum has a very low global production and is expensive, about twice that of gold.
