Could lithium batteries be the future of new energy vehicles

New energy vehicles in recent years as if dormant for many years, waiting for the opportunity to move the actor, after waiting for an opportunity, a appear, on the explosion overnight red, but a lot of people think that new energy vehicles and fuel cars compared, is a small fresh meat level, little imagine, it is actually and fuel cars with the age of the "old bacon". The world's first electric car predates the internal combustion engine. In 1873, Robert Davis, a British man, made the world's first practical electric car.

At present, the world's new energy vehicles are divided into a variety of, mainly: pure electric, hybrid, new fuel vehicles.

Although hybrid is a relatively popular new energy vehicle at the present stage, if we want to completely get rid of fuel oil, then the ultimate form of new energy vehicle development in the future, hybrid models will be gradually phased out, pure trams and new fuel vehicles will take place.

However, I think the most promising development in the future is the new fuel, because the shackles of the new fuel is relatively less.

At present, the pure charge can be divided into several groups, such as pure with a battery electric cars-and companies like byd has accomplished in lithium batteries, not in the battery, motor, electric control and other new energy vehicles is limited by technology, so its development prospects relative to other restricted by technology of auto enterprises to better, even tesla so once favored by the industry of car companies, because they do not have independent production capacity of the battery, led to a serious shortage of production capacity, so go to the point of very dangerous. As the main use of the car is lithium ion battery, this kind of battery can be recycled, this kind of rechargeable battery was born in 1996, the safety, capacity, cost performance and so on have been improved a level.

There are also carmakers specialising in hydrogen, such as Toyota, Honda and hyundai. ClarityFuelCell Mirai of Toyota, Honda, modern Nexo, hydrogen fuel compared to pure electric vehicles, charging time is short, so also have greater range, its energy conversion efficiency can reach 60%, and won't produce any pollution, can do real zero emissions, but the shackles of hydrogen fuel is there much, such as to store hydrogen fuel, is a very technical things, believe that back you junior high school chemistry elements table, all know that hydrogen is the top of the list, inside it there is only one electron, therefore the volume of a hydrogen atom is very small, even if again populated container, Hydrogen atoms also escape easily, and they're less stable and can be dangerous if you're not careful.

At present, the technology of hydrogen is relatively immature, leading to its rising cost. Coupled with inadequate infrastructure, hydrogen has a long way to go. Similar and methanol fuel, methanol is relatively better, however, because of its cheap, and also won't produce pollutants, but its energy density is small, compared with the same volume of gasoline, methanol car range of shorter, and corrosive to metal, use of methanol fuel cars, need to be specially engineered engine, but the methanol has been listed as future development of alternative fuels, despite the filling station and other infrastructure, its prospect is very considerable, at present, the geely automobile in the study had considerable attainments, methanol automobile unveiled a methanol car.

Of course, one of the industry's biggest surprises is graphene batteries. I have to mention that zhengdao group is very dedicated to graphene batteries. At this year's Beijing auto show, zhengdao group unveiled its plug-in electric vehicles H500, K350 and HKGT. They prefer to use their own fuel and generator extender to charge the battery, so that the range of these vehicles can reach or exceed 1000km. Graphene batteries, which the company has been working on, can also achieve a combined range of 1,000 km. Moreover, it has the advantages of long life of the core components and 100% increase of the program.

Graphene batteries can be used because lithium ions can move rapidly and massively between the graphene surface and the electrode, which can compress the charging time to the maximum. However, it has to be said that graphene is quite expensive. If we can achieve mass production in the future and reduce the cost, that would be great.
