Honda Extracts Rare Earth Metals to Make New Batteries

Honda developed a new method, which is extracting rare earth metals from the waste batteries and other products for recycling and manufacturing new batteries again.

There is no doubt that electric vehicles and hybrid electric vehicles are cleaner cars. Compared to fuel vehicles, they emit lower, even zero exhaust gas.

Whether grid charging emits greenhouse gas depends on the source, but the battery itself is also a problem. In addition to the greenhouse gas, mining rare earth metals also produce pollution.

Recycling can reduce the demand for raw materials extraction, such as aluminum, whose recycling utilization rate of 100%. Compared with mining aluminum ore, recycling consumes less time and energy, and lowers greenhouse gas emissions at the same time.

Honda revealed they can extract more than 80% of the rare earth metal from those used batteries to make new electrodes of  new batteries. In this way, The demand for new materials will be reduced to below 20%.

Later, Honda plans to expand the recycling project to other rare earth sources, including old batteries from electric motorcycles as well as scrap metal recycle bins.
