Environmental Benefit Assessment of Second-Life Use of Electric Vehicle Lithium-Ion Batteries in Multiple Scenarios Considering Performance Degradation and Economic Value

Environmental Science & Technology (2023)

Jiaying Cui Quanyin Tan Lili Liu Jinhui Li

Second-life use of electric vehicle lithium-ion batteries (LIBs) is an inevitable trend; however, battery performance degradation increases environmental loads. This study evaluated the life cycle environmental impacts of second-life use of LIBs in multiple scenarios, considering performance degradation and economic value. The results showed that a component replacement rate of retired LIBs below 50% made the batteries worthy of repurposing. Reusing whole packs of retired LIBs was better than using only cells or modules owing to the environmental loads from diagnosis, disassembly, replacement, and test processes. The battery energy density and performance degradation significantly affect the maximum return on the environmental input. Compared with lithium iron phosphate (LFP) batteries, new lithium nickel manganese cobalt oxide (NMC) batteries, or lead-acid batteries, using retired NMC-811 batteries with capacities as low as 60.7% for energy storage systems to store wind electricity rather than hybrid or photovoltaic electricity, had substantial environmental benefits, including a low global warming potential. Considering the costs of battery recycling, labor, and electricity, using whole packs of retired LIBs could simultaneously achieve high economic and environmental values in energy storage and peak shaving scenarios.

The Role of Oxalic Acid in the Leaching System for Recovering Indium from Waste Liquid Crystal Display Panels

ACS Sustainable Chemistry & Engineering (2019)

Jiaying Cui Nengwu Zhu Deliang Luo Yao Li Pingxiao Wu

In this study, oxalic acid showed better performance than inorganic acid in the indium leaching system from waste liquid crystal displays. The In3+ leaching efficiency with the powder dosage of 50 g/L came up to 100% within 45 min, using 0.5 M oxalic acid and stewing at 70 °C. Ultrasonic cavitation can improve the powder dosage. Combined with the substance analysis using ICP, XPS, SEM, and XRD, In2O3 dissolution depended on the distributive H+ concentration. Metal hydrolysis was a general negative phenomenon for ions loss in an acid leaching system. According to the Arrhenius model, the apparent activation energy for the indium leaching reaction was 43.622 kJ/mol, indicating that the indium leaching rate was mainly affected by the ion diffusion process through the solid–liquid interface and the chemical reaction process. Oxalic acid can maintain an appropriate H+ concentration to reduce the acid consumption from nontarget substances to relieve the powder surface corrosion for reuse and to inhibit metal hydrolysis, and its C2O42– ions also could precipitate some metal impurities such as Ca2+ and Sr2+ in the leachate.
