Where are the ternary lithium batteries and hydrogen fuel cells different?
At the same time of scientific and technological progress, it has also accelerated environmental pollution. The earth's resources will never end. The goal of actively developing renewable energy has been accelerating. We advocate environmental protection and environmental protection has become the theme that will never disappear in the present era.
With the increasing environmental pollution, smog has become a topic of discussion in recent years. Especially in the Imperial Capital, the imperial city that once stood majestic was also covered by the smog. As the world's oil resources continue to be mined, the days of "refueling" are getting farther and farther away from us. As a big car country, China naturally cannot be "oil". Ever since, advocating energy conservation and environmental protection has become the slogan of the country. With the development in recent years, new energy vehicles have emerged as a clean stream and have generated a hot topic. Major auto companies have joined the ranks of the new energy army.
The reason why new energy vehicles are developing rapidly is that they rely on batteries as the power source, which is different from traditional fuel vehicles. Pollution-free has become its biggest advantage, and it is reasonable for the state to pay for subsidies. As the core of electric vehicles, batteries have naturally become the focus of research and development of domestic and foreign car companies.
The batteries we are familiar with are also widely used by electric vehicles. One is a ternary lithium battery represented by Zotye, and the other is a hydrogen fuel cell headed by Toyota. Looking at the current development of electric vehicle batteries, these two types of batteries. There is still a big difference.
Let's talk about the ternary lithium battery that is favored by the new audience. First of all, the ternary lithium battery has high energy density and good cycle performance, thus extending battery life. With the rapid development of science and technology, major auto companies at home and abroad have designed their own battery management system, which ensures the safety of electric vehicles.
Fuel cell vehicles, as the name suggests, are based on fuel cells, and this technology is still not mature in China. However, it is widely used in some developed countries such as the United States, Japan, and South Korea. Especially in Japan, the largest automaker has already worked hard on hydrogen power. Toyota has launched Mirai, a new energy vehicle powered by hydrogen fuel, more than a year ago. It has already been sold in Japan.
There are many fuels for fuel cells, such as hydrogen, methane, ethanol, etc. The main fuel is hydrogen. Therefore, fuel cells are generally hydrogen-oxygen fuel cells. Fuel cells convert chemical energy directly into electrical energy, and then convert electrical energy into mechanical energy of the motor. There is no direct combustion process; the hydrogen internal combustion engine converts the chemical energy of hydrogen into heat and kinetic energy through combustion, and then converts this energy into mechanical energy through a reciprocating piston.
This fuel cell is different from the traditional lithium-ion battery, which can quickly fill the battery with fuel in 3-5 minutes, and the cruising range is farther. For traditional new energy car charging, this has become a luxury. Of course, in addition to convenient charging, hydrogen fuel cells still face many difficulties. Hydrogen fuel consumes more energy than ordinary electric vehicles, and pollution naturally becomes a big problem. Secondly, the price and maintenance cost of fuel cell vehicles are more expensive than electric vehicles. Compared with electric vehicles that are relatively environmentally friendly and economical, hydrogen fuel cell vehicles are eclipsed.
The rapid development of new energy vehicles has also driven the vitality of the battery industry, and also represents the development trend of the new energy vehicle industry.
