Why can’t the lithium battery of electric bicycle be traded in?
Everyone is no stranger to the "battery-for-new" issue. But whether this battery refers to a lead-acid battery or a lithium battery, there may not be many people who know it. In fact, almost all lead-acid batteries can be used for trade-in and recycling. So, why can't lithium batteries for electric bicycles be recycled? Lithium batteries that cannot be exchanged for new ones, are they more expensive to use than lead-acid batteries, and are they less cost-effective?
First of all, lead-acid batteries can be recycled, mainly due to the following two reasons:
1. The raw materials of lead-acid batteries contain harmful substances such as lead and sulfuric acid, so waste lead-acid batteries must be processed and recycled;
2. Lead recycling technology has matured, and lead recycling has also entered formalization and industrialization.
Lithium batteries for electric bicycles cannot be recycled at present, mainly due to the following three reasons:
1. At present, the recycling technology related to lithium batteries is not yet mature. With the in-depth research and technological progress in the future, it may also enter the industrialization like the recycling of lead-acid batteries.
2. The raw materials of lithium batteries are carbon, graphite, lithium metal oxides and a small amount of electrolyte, which are environmentally safe and will not be harmful without special treatment.
3. The service life of lithium batteries is much longer than that of lead-acid batteries. When used correctly, the cost per kilometer is much lower than that of lead-acid batteries. Even if it is not recycled, it is cost-effective to use.
