The Technology Of Iron Phosphate Lithium Battery Is Mature, Why Is Electric Bicycle Rarely Used?

"Why don't electric bicycles be completely converted into lithium iron phosphate batteries?" Recently, a car friend commented on this question. The reason why "expensive" electric bicycles are not suitable for lithium batteries can be summarized. Lithium iron phosphate batteries have no heavy metals and battery recycling. The rate is more than 95%, the electrolyte is almost non-polluting, and some types can even drink. The price of so many batteries is naturally not low.

Although the price is lower than the ordinary nickel-cobalt-manganese ternary lithium battery, the sales price per kwh is also about 1,500 yuan. The price of some miscellaneous electric bicycles is only over 1,000 yuan, allowing consumers to pay more. The price is only for environmental protection. How many people are willing to pay?

Although the lead-acid battery has serious heavy metal pollution and the electrolyte is sulfuric acid, the price is low enough. After the limit of 48V, the cost of the ordinary 12V-20a battery is also half the cost of the lithium iron phosphate battery. If the old one is replaced, the price can be much lower.

However, the actual cost of the iron-lithium battery is still very cost-effective. The number of cycles of replaying more than 2000 times can ensure that the capacity attenuation is controlled at about 70%, while the ordinary lead-acid battery is also 1/3 of the level of the iron battery. Not enough. Therefore, according to the frequency of power exchange calculation, the iron battery is actually worthwhile, but the excessive budget of the car has prevented many consumers from enthusiasm.
