Why have lithium battery electric vehicles only become popular until now?

As we all know, electric vehicles have many advantages, such as light weight and convenient operation, but the disadvantages are also obvious-short cruising range. Most electric vehicle companies focus on the battery to deal with the short range. After the invention of the rechargeable lead-acid battery in 1859, battery technology has been rapidly developed. In 1881, the world's first electric car was born as a tricycle powered by a lead-acid battery. But the weight of lead-acid batteries has always been a pain point for all electric vehicle companies. The use of lead-acid batteries has greatly increased the quality of electric vehicles, which cannot meet the requirements of lightness of electric vehicles themselves, and this has resulted in later lithium batteries. Lithium batteries for electric vehicles have the advantages of high voltage, large specific energy, long cycle life, good safety performance, low self-discharge, and fast charging speed. Lithium batteries were born 40 years ago and were developed by British American John Goodenough (John Goodenough is known as the father of lithium batteries). In fact, it was British chemist Whittingham who first discovered the room temperature charging ability of lithium ion. However, due to not well handled, the lithium battery electrode crystallization short-circuit problem, in the use after subsequent processing, the lithium battery fire and explosion often occur one after another. In this context, Goodenough and his team started research on lithium batteries. The Gudinaf team continued four years of research and found in 1980 that the use of oxide lithium cobalt oxide materials can improve the crystallization problem of lithium electrodes. Two years later, in 1982, the Goodenough laboratory discovered a more stable and cheaper material, lithium manganate. The world's first lithium battery electric car was born in 1996, more than 20 years ago. Since lithium batteries have so many advantages, why have they just been popularized until now? A large part of the reason is that the price is too expensive. With the development of society, electric vehicles are progressing in science and technology, and the quality of life is improving. People's requirements for electric vehicles are more and more not just confined to the present. Due to the limited volume of electric vehicles, the volume of lithium batteries is limited, which leads to short cruising range of electric vehicles, which cannot meet people's current requirements. This is also the country has been encouraging the popularization of electric vehicles, until now there are no signs of starting.
