Researchers have developed a new recycling method that can extract 99.99% of lithium from old lithium-ion batteries, addressing the growing issue of e-waste from smartphones and electric vehicles. This eco-friendly technique, created by a team from Central South University and Guizhou Normal University in China, utilizes micro batteries to break down lithium, nickel, cobalt, and manganese, employing glycine as an amino acid to avoid harsh chemicals and toxic byproducts. The process can recover significant amounts of other metals as well: 96.8% of nickel, 92.35% of cobalt, and 90.59% of manganese, all within just 15 minutes. This breakthrough is particularly important as the demand for consumer electronics and electric vehicles continues to rise, leading to increased battery waste. A report from Stanford University highlights that recycling lithium-ion batteries is more environmentally friendly than mining new materials, yet current methods can still harm the environment. The new method, detailed in the journal Angewandte Chemie International Edition, presents a sustainable solution for large-scale, pollution-free recycling of spent batteries, marking a significant advancement in battery waste management.
