What are the old batteries used for in battery trade-in programs?

Recycling. Detailed introduction is as follows: Lead metal: Electric vehicle batteries contain large amounts of lead metal, which can be recycled and refined for reuse. This not only saves resources but also prevents valuable raw materials from being discarded and polluting the environment. Currently, 55% of lead production comes from recycled lead. In the recycled lead industry, the recycling of waste lead-acid batteries accounts for a large proportion. 100 kilograms of waste lead-acid batteries can recover 50-60 kilograms of lead. Reusable materials: The reason why old batteries have relatively high recycling value is that they contain many reusable materials. After recycling, these materials will be tested by professionals and processed according to their condition. After being repaired and improved, they will be used in electric vehicles. This is equivalent to purchasing the materials for battery production.

When I worked at an auto repair shop, this was the most frequently asked question by car owners. The recycled old batteries actually go through a professional dismantling process. Specialized companies break open the casing and separate the lead plates and lead paste inside. Lead is a particularly valuable metal, with a recycling rate of over 95%. The plastic casing can also be reused after being crushed and cleaned. The most difficult part to handle is the waste acid, which needs to be neutralized before discharge. Currently, several large domestic recycled lead enterprises, such as Tianneng and Yuguang, have established professional recycling lines. Formal recycling is not only profitable but also crucial to avoid lead pollution of soil and water. Therefore, we encourage car owners to hand over their old batteries to formal recycling points.

As a veteran taxi driver with 20 years of experience, I've replaced at least a hundred batteries. The lead plates inside those old batteries are the real treasure - factories melt them down to make new battery plates. And those black plastic casings may look worthless, but when properly processed, they can be recycled into plastic pellets. What most people don't realize is the most dangerous part - the acid electrolyte. If not handled properly, it can contaminate groundwater. That's why I always recommend going to authorized service centers for battery replacement. I've seen too many small shops in auto parts markets carelessly dumping the acid. Environmental protection is no trivial matter - we all need to be more responsible.

In my years of researching eco-friendly materials, what surprised me most is the circular economy chain of lead-acid batteries. Nearly 70% of materials in each used battery can be fully recycled. Through furnace refining, recycled lead achieves 99.97% purity. The polypropylene plastic casings are crushed into pellets and reused for molding new casings. Leading enterprises have now achieved a 97% material recovery rate. China annually recycles 2 million tons of used batteries, saving enough lead ore to fill 30,000 heavy trucks. Next time you replace a battery, remember to check the recycler's qualifications - legitimate companies all possess hazardous waste treatment licenses.
