As major national policies are helping the development of new energy vehicles, many subsidy policies have accelerated the growth of new energy vehicles, but the popularity of new energy vehicles is followed by the recycling of retired batteries.

When a large number of power batteries are retired, the first thing to consider is the pressure of environmental protection, because the heavy metals, electrolyte solutes, organic solvents, etc. in the batteries are polluting, so the recycling of power batteries is necessary.

The recycling and reuse of power lithium batteries is the intermediate link between new energy vehicles and the reuse of power lithium batteries. Since 70% - 80% of the power battery capacity can still be used after the replacement of the power battery, if the power battery is directly recycled, it will cause great waste. Realizing the series recycling of the power battery can achieve the purpose of reducing the cost of the power battery by 30-60%.

The power lithium battery echelon utilization terminal is mainly for household energy storage, storage, new energy distributed generation, disaster prevention headquarters, communication base stations, micro electric vehicles, electric bicycles and other fields. The energy density requirements of these applications are relatively low, but the cycle life and price requirements are relatively strict. Considering the multiple costs of battery recycling, conversion and transportation, the actual recycling value of old batteries used in vehicles is only about 10% of the cost of new batteries, which can meet the price requirements, but the verification of cycle life needs to be considered in battery design. Ensure the life requirements of reuse links.
