電気自動車の電池としては、何世代かの発展を経て、鉛電池が始まりました。その後、ニッケルカドミウムとニッケル水素電池、最後はリチウム電池です。これはリチウム電池には独特な点があるということです。リチウム電池は、エネルギー密度、電力比、サイクル寿命のいずれからも最適です。
しかし、現在の最高のリチウム電池は500キロぐらいの航続能力しかないです。これは理想的な状況ですので、ガソリン車のレベルには達しません。新しい電池を開発するのは新エネルギー車の回りくどい任務です。
新型電池の努力は多面的で、グラフェン電池、金属空気電池、リチウム硫黄電池、スーパー容量電池などがあり、いずれも自動車産業の革命を引き起こす。しかし、今最も突破可能なのは固体電池で、実験室で実証されたはずです。大企業は一刻を争う研究開発をしています。誰が先に量産するかを見ます。
但目前最好的锂电池还是只能作到500公里左右的续航能力，这个还是理想功况下的，所以达不到燃油车的水平。开发新的电池是新能源汽车的绕不过的任务。
新型电池的努力是多方位的，有石墨烯电池，金属空气电池，锂硫电池，超级电容电池等等，任何一种取得突破都将引起汽车业的革命。但目前最有可能突破的是固态电池，应该在实验室得到了证实，大公司们都在争分夺秒的研发，看谁最先量产。
燃料电池汽车目前最具代表性的是丰田的MIRAI，续航500多公里，还可充当移动发电站，后备箱的插座，够普通家庭一星期的用电。两大弊端，一是用700个大气压的压力储氢，一旦泄漏或爆炸后果都不堪设想。再是加氢站太少，无处加氢。催化剂用铂并不是大问题，一是用量少，二是已出现替代物。As batteries for electric vehicles, after several generations of development, they began as lead-acid batteries, followed by nickel-cadmium and nickel-hydrogen batteries, and finally lithium batteries. This shows that lithium batteries are unique. Whether in terms of energy density, specific power or cycle life, lithium batteries are the best choice at present.
But at present the best lithium batteries can only run for about 500 kilometers, which is still under ideal conditions, so it can not reach the level of fuel vehicles. Developing new batteries is an unavoidable task for new energy vehicles.
The efforts of new batteries are multifaceted, including graphene batteries, metal-air batteries, lithium-sulfur batteries, supercapacitor batteries and so on. Any breakthrough will lead to a revolution in the automotive industry. But the most likely breakthrough at present is solid-state batteries, which should be confirmed in the laboratory. Large companies are scrambling for research and development to see who is the first to produce the batteries.
At present, the most representative fuel cell vehicle is Toyota's MIRAI, which lasts more than 500 kilometers. It can also serve as a mobile power station and a socket in the backup box, which can be used by ordinary families for one week. One of the two drawbacks is that hydrogen is stored at 700 atmospheric pressure, and the consequences of leakage or explosion are unimaginable. Then there are too few hydrogenation stations and no place for hydrogenation. Platinum used as catalyst is not a big problem. One is low dosage, the other is that substitutes have appeared.
