The power battery pack used in new energy vehicles is lithium batteries, and the batteries used in traditional vehicles are lead batteries. Therefore, the difference between new energy batteries and traditional car batteries is still very large.

First of all, in terms of battery materials, the lithium batteries used in new energy vehicles are composed of metal lithium aluminium alloys and lithium-ion polymers; the materials of lead batteries are metal lead and lead dioxide. Regarding price, the materials used in lead batteries are cheaper than those used in lithium batteries, so the overall price of batteries is also cheaper.

Furthermore, from the perspective of energy density, the energy density of lithium battery packs used in new energy vehicles is higher, reaching 200-260wh/g; the energy density of lead-acid batteries used in traditional vehicles is even lower, basically only reaching 50~70wh. /g. And at the current level of technology, the energy density of lithium batteries is constantly increasing, while the energy density of lead batteries can only remain unchanged.

Then there is the service life. Lithium battery packs used in new energy vehicles have a longer service life than lead batteries used in traditional vehicles. The cycle charging times of lithium battery packs can reach about 2000 times, and the cycle charging times of lead-acid batteries used in traditional automobiles is generally about 300-350 times.

Now new energy vehicles generally use lithium battery packs, and the advanced level of lithium battery pack technology is also a major factor restricting the development of electric vehicles.
