Chapter 7: Electric Vehicle Batteries, Energy Storage Systems, and Recycling
Abstract : Electric Vehicle (EV) batteries, after their life in cars (around 70-80% capacity), are perfect for Battery Energy Storage Systems (BESS) like grid stabilization or backup power, extending their life and reducing waste before final recycling to recover valuable materials like lithium, cobalt, and nickel through methods like pyrometallurgy or hydrometallurgy , creating a circular economy for sustainable energy . Repurposing for energy storage often offers greater environmental benefit than immediate recycling, while new battery tech and connected management systems (BMS) focus on improved performance, safety, and cybersecurity for future use. EV Batteries & Energy Storage Systems (BESS) Second Life: Used EV batteries (still 70-80% capacity) are ideal for stationary storage in homes, businesses, data centers, or for integrating renewable energy (solar/wind) due to slower, less intense cycling needs. Benefits: Exte...
