點(diǎn)擊量：次
電気自動(dòng)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獨(dú)特な點(diǎn)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、サイクル壽命のいずれからも最適です。
しかし、現(xiàn)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。これは理想的な狀況ですので、ガソリン車のレベルには達(dá)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(wù)です。
新型電池の努力は多面的で、グラフェン電池、金屬空気電池、リチウム硫黃電池、スーパー容量電池などがあり、いずれも自動(dòng)車産業(yè)の革命を引き起こす。しかし、今最も突破可能なのは固體電池で、実験室で実証されたはずです。大企業(yè)は一刻を爭う研究開発をしています。誰が先に量産するかを見ます。
但目前最好的鋰電池還是只能作到500公里左右的續(xù)航能力，這個(gè)還是理想功況下的，所以達(dá)不到燃油車的水平。開發(fā)新的電池是新能源汽車的繞不過的任務(wù)。
新型電池的努力是多方位的，有石墨烯電池，金屬空氣電池，鋰硫電池，超級(jí)電容電池等等，任何一種取得突破都將引起汽車業(yè)的革命。但目前最有可能突破的是固態(tài)電池，應(yīng)該在實(shí)驗(yàn)室得到了證實(shí)，大公司們都在爭分奪秒的研發(fā)，看誰最先量產(chǎn)。
燃料電池汽車目前最具代表性的是豐田的MIRAI，續(xù)航500多公里，還可充當(dāng)移動(dòng)發(fā)電站，后備箱的插座，夠普通家庭一星期的用電。兩大弊端，一是用700個(gè)大氣壓的壓力儲(chǔ)氫，一旦泄漏或爆炸后果都不堪設(shè)想。再是加氫站太少，無處加氫。催化劑用鉑并不是大問題，一是用量少，二是已出現(xiàn)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.
