After a power battery reaches 70% of its battery capacity, it can no longer work in the original "job", but the retired power battery, if its module is qualified, can also be used in echelons for other places with battery demand. So what is the power battery cascade utilization, and what is its significance? Let's introduce Pengmi Technology.
To put it simply, it refers to the process of continuing to use a used product that has reached the original design life, and then restores its function in whole or in part through other methods, which belongs to the same or downgraded application.
For power batteries, cascade utilization is a high-power used lithium battery, which is disassembled, tested and reassembled, and then used with low power until it is scrapped.
1. Profitable.
Only when an industry is profitable can it develop commercially and form a certain scale, and the same is true for the cascade utilization of power batteries. With the popularization of new energy vehicles, the production of battery materials is slowly growing, 600,000 tons of cobalt metal, 100,000 tons of nickel, 170,000 tons of lithium carbonate, and 900,000 tons of lithium metal.
The power battery can be dismantled and dismantled, and these materials can be obtained from it and benefits. In the future, the amount of scrapped new energy vehicles will increase, and the number of scrapped power batteries will also increase year by year, and the market prospect is very broad.
2. Save resources.
Power batteries contain a large number of metal elements, such as nickel, cobalt, graphite, etc., among which metal elements such as cobalt and lithium are relatively scarce in China, because they are difficult to mine, cobalt is generally distributed in mines, Qinghai, Sichuan and other difficult conditions, and the magnesium ion content in the salt lake is relatively high, and the difficulty of extracting lithium is also very large.
Therefore, the reuse of power batteries, to a certain extent, can increase the supply of resources and save resources.
3. Protect the environment.
There are heavy metal elements such as nickel, cobalt, manganese, and lithium inside the power battery, which will cause irreversible damage to the environment if discarded at will.
