Replacing batteries in new energy vehicles generally costs tens of thousands or even hundreds of thousands. At present, the battery life of new energy vehicles is relatively long, generally more than ten years. But when it comes time to replace the battery, the technology will advance, the technology will develop and the cost will be low. The actual price may only be a fraction of the current price.
Lithium-ion batteriesThere are two different types:
Today, new energy vehicles mainly use lithium-ion batteries. However, lithium-ion batteries are also divided into different types based on the materials of their positive electrodes. It is used in two types of new energy batteries, one is lithium iron phosphate battery.
The other is a batternary lithium polymer erie containing three elements: cobalt, manganese, and nickel. We will talk about ternary lithium batteries later.
The lifespan of lithium batteries is limited:
Although such a lithium battery can be charged repeatedly, its lifespan life is also limited. With prolonged use, the active lithium and active materials in the battery will be lost and the battery will end its life. It's as if the lithium ions were workers and the active materials were factories. There are no more workers, the factory has closed its doors and there are no more products. A pair of shoes costs 80 yuan.
For power batteries, the industry generally believes that when the capacity is less than 80% of the original, they are considered to be at the end of their life, not completely de-energized.
