Can high voltage batteries be recycled?

High-voltage (HV) batteries are recyclable. Primarily composed of lithium-ion cells, these batteries are typically utilized in applications such as electric vehicles and energy storage systems, characterized by their high capacity and high voltage. Once they reach the end of their limited service life, high-voltage batteries can—through appropriate recycling methods and equipment—not only be safely disposed of but also serve as a source for extracting valuable materials, thereby facilitating resource recycling.

However, the direct recycling of high-voltage lithium batteries is inadvisable. Safety is paramount in HV battery recycling, as their inherent high-voltage characteristics pose potential risks of electric shock or fire; consequently, preliminary discharge treatment is mandatory. The standard recycling process typically comprises the following steps:

High-voltage HV lithium battery recycling process

1. Safe Pre-treatment and Discharge: Using specialized discharge equipment, the residual electrical energy within the battery is safely released to prevent the risk of electric shock or fire during subsequent processing stages. This process typically involves soaking the battery in saltwater for two to three days until its charge drops to a safe level (below 2V).

2. Module Disassembly and Crushing: The discharged battery packs proceed to the disassembly stage, where specialized equipment is used to break them down into individual battery cells. Subsequently, these battery materials are fed into lithium battery recycling machinery for mechanical crushing. The crushing system pulverizes the materials into smaller particles, thereby preparing them for the subsequent material separation stage.

3. Material Separation and Enrichment: The crushed mixture undergoes separation using various techniques—such as physical sorting, airflow classification, and screening—to isolate components including plastic diaphragm, metal casings, and cathode/anode materials (black powder). The objective of this stage is to maximize the enrichment of valuable metals, thereby enhancing the overall efficiency of the recycling process.
