New paper published in ACS Sustainable Chemistry & Engineering. We present a mildly synthesized aluminum layered double hydroxide (Al-LDH) electrode that couples chemical adsorption with electrochemical release to recover lithium at neutral pH, eliminating harsh acids or bases and minimizing secondary pollution. It achieves an average Li+ uptake of 57.6 mg/g with strong Li+ over […]

Liying Xue presents our work on multi-component composition materials at the at the 40th topical conference of the International Society of Electrochemistry with the exciting topic of interfacial electrochemistry and related topics. Her poster has the title: “Multi-element synergy to enhance the cycling performance of oxalates as anode materials for lithium-ion batteries” and she will […]
New paper published in ACS Applied Energy Materials on lithium-sulfur batteries. Our collaborative work explored microporous carbon cathodes with carefully tuned pore sizes, tested in both carbonate- and ether-based electrolytes. Our study shows how pore structure and cathode–electrolyte interphase formation impact cycling stability and sulfur utilization. With optimized microporosity, we achieved over 50 mass % […]
New paper published on electrochemical lithium-ion battery recycling in Energy Advances. We demonstrate a sustainable, energy-efficient electrochemical route to recover Li⁺ from spent LFP using carbon-coated LFP electrodes, with NaOH-adjusted electrolytes giving the highest efficiency and an average removal capacity of 18 mg Li per 1 g of LFP over 50 cycles. Capacity fades with […]
We are grateful for the Minister to take time to visit the science exhibition ship MS Wissenschaft, anchoring in Saarbrücken, Germany. We discussed climate change, scientific discoveries, basic and applied research – specifically as it pertains to our research on lithium-ion battery recycling.
New collaborative paper (Victor H. R. Souza) published in Journal of Power Sources. To support the energy transition, we developed freestanding electrodes combining reduced graphene oxide, polyaniline, and nickel hexacyanoferrate (NiHCF), which is a promising material for aqueous batteries due to its long cycle life and redox-active structure. These rGO/PAni/NiHCF films achieve high specific capacities […]
