1. Sustainable recycling of Li-ion batteries
Abstract : Lithium-ion batteries (LIBs) play a key role in today’s energy storage sector, finding applications in everyday use electronic devices, like smartphones, laptops or electric vehicles. Despite very good properties, such as high electric capacity and high number of charge-discharge cycles, eventually each battery in the world will be disposed and stored in a landfill, waiting for the opportunity to be recycled.

2. Effects of pyrolysis and incineration on the chemical composition of Li-ion batteries and analysis of the by-products
Abstract : In the present work, the effects of pyrolysis and incineration on the composition of Li-ion battery cell materials and their dependence on treatment time and temperature were investigated. Waste from Li-ion batteries was treated at 400˚, 500˚, 600˚, and 700˚C for 30, 60, and 90 minutes. READ MORE

5. Investigation of HEV Li-ion Batteries for Lithium Recovery
Abstract : Automobile electrification is one of the technological developments that may establish aneco-friendly transport system by mitigating vehicle emissions, and hopefully lead to a lessfossil fuel-dependent society. Conservative forecasts predict four million electric cars onthe road by 2015 (Bernhart et al., 2012). READ MORE
