Fuel - powered batteries and lithium-ion battery technology which will become the mainstream lithium-ion battery for vehicles? At present, lithium-ion batteries and fuel-powered batteries are the mainstream technology routes to replace petroleum vehicles. The biggest advantage of fuel power battery is its high energy density, but lithium ion battery started early, has a higher degree of commercialization, and the cost of the whole vehicle is lower. Moreover, the charging can use the existing power grid system. Compared with fuel power battery, the entire supporting network of hydrogenation and hydrogen supply has to be built from scratch, and the cost is lower. So the core of the competition between the two is energy density versus cost.

Fuel - powered batteries and lithium-ion battery technology which will become the mainstream lithium-ion battery for vehicles?

Currently solid state lithium ion batteries to earlier than hydrogen fuel power battery by promoting use of solid state lithium ion battery technology is relatively mature, has the certain commercial USES, and hydrogen fuel power battery to replace fuel car is expected to take the lead in in long-distance overloading, solid state lithium ion batteries belong to the liquid lithium electricity system upgrade, the future in the field of new energy vehicles have the possibility of large scale, Hydrogen fuel-powered batteries have been used in the field of new energy vehicles, and most new energy lithium ion battery manufacturers have also begun to promote hydrogen fuel-powered batteries.

In fact, hydrogen fuel-powered cell cars and lithium-ion battery type electric vehicles are basically the same, both rely on electric motors to drive, but the biggest difference between the two is the way electricity is produced and stored. Lithium-ion battery-powered pure electric cars get their electricity from an external source, known as charging, but hydrogen-powered batteries have their own "generator" and are quiet, unlike extended-range electric cars, which run on internal combustion engines.

Fuel powered cells and lithium-ion batteries are compared

1. Lithium ion batteries have the advantages of high ionic conductivity, high mechanical strength and high energy density. Benefit from the original technical accumulation and industrial resources in the field of lithium ion batteries in China, mass production can be realized with low cost. Fuel - powered cells are another branch of development that is also gaining traction.

2, Fuel power cell has the characteristics of light weight, long life, high energy density, short recharge time, longer range and no environmental impact. However, its key components such as proton exchange membrane, catalyst, bipolar plate and other core technologies have been monopolized by foreign countries for a long time, which seriously restricts the development of the industry. Moreover, hydrogen energy ecological chain fully supporting hydrogen production, hydrogen storage and hydrogen processing has not been formed in China, and hydrogen energy infrastructure construction is insufficient, making it difficult to be widely promoted in a short period of time.

3. The major obstacles to the development of fuel-powered cells are the high cost, the complexity of the hydrogen production process, and the need to build the entire hydrogenation and hydrogen supply network from scratch. Hydrogen is obtained by electrolysis or steam recombination. But both methods are expensive, with the cost of producing gas of the same quality at half or even a third of that of producing hydrogen. Lithium-ion batteries are relatively cheap to produce and are easily recharged, making them more cost-effective than other portable energy sources.

The large number of household passenger cars and buses and their shorter distances make them more suitable for carrying lithium ion batteries with high energy density and small volume. Moreover, compared with fuel power batteries, the technology of lithium ion batteries is relatively mature. Commercial vehicles, logistics vehicles and heavy trucks should have sufficient passenger space and long endurance capacity. The loading of solid lithium ion batteries will take up space and increase the load, while the fuel power battery itself is light, and the fuel enters the vehicle body for power supply with the help of external circulation, so it is actually the first choice to replace the fuel power in the aspect of long-distance and heavy load.

Theoretically hydrogen fuel power battery is 100% energy of environmental protection, the principle of hydrogen fuel power battery is made up of hydrogen and oxygen produces chemical reaction, the energy is converted into electrical energy, and thus drive cars, hydrogen combustion of "waste" is water, completely don't cause pollution to the environment, so quite a number of experts believe that hydrogen fuel will be the future eventually substitute for petrol.

From the perspective of these two technologies, lithium-ion batteries are better in terms of energy efficiency, safety and basic supporting facilities, while fuel power batteries are more mature in terms of battery life technology. In the long run, electric vehicles are definitely the direction of future automobile development. Although the current mainstream is lithium ion battery, hydrogen energy also has considerable potential as an environmentally friendly raw material with zero pollution.
