Can a car equipped with a lead acid battery be replaced with a lithium battery?

Yes, but at least two questions need to be considered. One is the issue of security; the other is the question of costs. There are currently four types of lithium batteries on the market, namely lithium manganate, ternary lithium, lithium iron phosphate and lithium titanate. Among them, ternary lithium batteries are more familiar to friends, including nickel-cobalt-manganese and nickel-cobalt-aluminum. With the different proportions of various materials, various subspecies can be included in great detail. However, in terms of safety, the safety factor of lithium batteries is not enough. Lithium cobalt oxide and ternary lithium cannot be selected as automobile starting batteries in the high temperature environment of automobile engine compartment. Lithium titanate has also experienced spontaneous combustion during use processes.real tion and repair. It's something that spontaneously ignites upon charging when used on an electric passenger vehicle. The remaining lithium manganate has a short lifespan, so it only has about 500 times and is not suitable as a starter battery. The lithium iron phosphate battery that can be used has no problem with its safety factor, and it also has the characteristic that the cell voltage reaches 3.65V when charging. Make a starter battery with a nominal voltage of 12 V and connect 4 of them in series. It can support a maximum voltage of 14.6V, which is quite close to the 14.4V of a fully charged 12V lead acid battery. When starting the battery, the operating current is often more than 200A at the time of starting, so the capacity should be at least 50Ah, and the market value of one cell is 2.5 yuan/1, which is cheap. 4 cells costtent 500 yuan. Four strings of 400 amp protection panels cost at least around 450 yuan. Insulating materials, waterproof materials and copper plates for connecting batteries in series are added. Even if you make such a battery yourself, the cost will be more than 1,000 yuan. After 5 years of use, even if you buy a Varta 12v60AH battery and use it for 6 or 7 years, the price will only be about 700 yuan. You can exchange the rest for at least 120 yuan, which is half the cost compared. to the use of lithium iron phosphate batteries. In terms of weight, although lithium batteries are lighter than lead-acid batteries, for a car that weighs one ton, the weight saved by the battery will not exceed 20 kilograms, which is not as good as d 'save 10 kilograms of load for one inhabited person. spatialship. When using lithium batteries as baStarting tteries in cars, issues such as safety and cost also need to be considered. Therefore, when choosing a battery, you need to consider all factors.
