Which will become the mainstream of automotive power r03 battery technology, fuel cell battery or lithium-ion battery technology? At present, the mainstream technology route to replace petroleum vehicles is lithium-ion battery and fuel cell battery. The biggest advantage of fuel cell battery is its high energy density, but lithium-ion battery started earlier, has a higher degree of commercialization, and has a lower vehicle cost. Moreover, charging can use the existing power grid system. Compared with fuel cell battery, the entire hydrogenation and hydrogen supply supporting network must be built from scratch, and the cost is also lower. Therefore, the core of the competition between the two is the competition of energy density VS cost.

Which one will become the mainstream of automotive power r03 battery, fuel cell or lithium-ion battery technology?

At present, solid-state lithium-ion batteries are promoted and applied earlier than hydrogen fuel cell batteries. Solid-state lithium-ion battery technology is relatively mature and has certain commercial uses. Hydrogen fuel cell batteries are expected to replace fuel vehicles first in long-distance heavy-load. Solid-state lithium-ion batteries are upgraded versions of liquid r03 battery systems. They are likely to be widely used in the field of new energy vehicles in the future. Hydrogen fuel cell batteries have already been used in the field of new energy vehicles. Most new energy lithium-ion battery manufacturers have also begun to promote hydrogen fuel cell batteries.

In fact, hydrogen fuel cell vehicles and current lithium-ion battery pure electric vehicles are similar in basic principles. They are both driven by electric motors, but the biggest difference between the two is the way electricity is manufactured and stored. The electricity of lithium-ion battery pure electric vehicles is supplied by the outside world, which is the charging we are familiar with, but hydrogen fuel cell batteries have their own "generators", and unlike extended-range electric vehicles that rely on internal combustion engines to generate electricity, hydrogen fuel cell vehicles do not make any noise.

Compared with lithium-ion batteries

1. Lithium-ion batteries have the advantages of high ion conductivity, high mechanical strength and high energy density. Benefiting from the original technical accumulation and industrial resources in the field of lithium-ion batteries in China, they can be mass-produced at a low cost. Fuel-power batteries, as another development branch, are also highly respected by the industry.

2. Fuel-power batteries have the characteristics of light weight, long life, high energy density, short refueling time, longer driving range and no environmental impact. However, its key components, such as proton exchange membranes, catalysts, bipolar plates and other core technologies, have long been monopolized by foreign countries, which seriously restricts industrial development. In addition, China has not yet formed a fully matched hydrogen energy ecological chain for hydrogen production, storage and refueling. The construction of hydrogen energy infrastructure is insufficient, and it is difficult to promote it on a large scale in a short period of time.

3. The important obstacles to the development of fuel-power batteries are high cost and complex hydrogen production process. The entire supporting network for hydrogen refueling and supply must be built from scratch. Hydrogen is obtained by electrolysis or steam reforming. However, these two methods are quite expensive. The cost of producing the same quality of natural gas is 1/2 or even 1/3 of that of hydrogen production. The production cost of lithium-ion batteries is relatively low. In addition, they are very convenient to recharge and reuse. Compared with other portable energy sources, they are more cost-effective.

There are a large number of household passenger cars and buses with short travel distances, which are more suitable for loading high-energy-density, small-volume lithium-ion batteries. Moreover, compared with fuel-powered batteries, lithium-ion battery technology is relatively mature. Commercial vehicles, logistics vehicles and heavy trucks need sufficient passenger space and long driving range. Loading solid-state lithium-ion batteries will take up space and add weight. Fuel-powered batteries are light in weight, and fuel enters the vehicle body through external circulation to supply power. They are the first choice to replace fuel power in long-distance and heavy-load situations.

In theory, hydrogen fuel-powered batteries are 100% environmentally friendly energy. The principle of hydrogen fuel-powered batteries is that hydrogen and oxygen undergo a chemical reaction, and the energy generated is converted into electrical energy to drive the car. The "waste" generated by hydrogen combustion is water, which does not pollute the environment at all. Therefore, many experts believe that hydrogen fuel is the ultimate substitute for gasoline in the future.

From the perspective of the two technologies, lithium-ion batteries are superior in terms of energy efficiency, safety, and basic supporting facilities, while fuel cell batteries are relatively stronger in terms of the maturity of their endurance technology. In the long run, electric vehicles are definitely the direction of future automobile development. Although lithium-ion batteries are the mainstream now, hydrogen energy also has considerable potential as a zero-pollution, environmentally friendly raw material.
