New open access paper published in ACS Applied Materials & Interfaces on “Understanding Rate and Capacity Limitations in Li-S Batteries Based on Solid-State Sulfur Conversion in Confinement”. This study explores how solid-state sulfur conversion within carbon nanopores enhances the performance of lithium-sulfur batteries. Key parameters relate to cathode-electrolyte interphase (CEI) formation, pore size, and material […]
Volker Presser gives an oral presentation titled “Electrochemical Lithium-Ion Separation” at the Symposium on Direct Lithium-Extraction (SDLE) at the Karlsruhe Institute of Technology (Germany).
Our latest research in Energy & Environmental Science explores an eco-friendly, high-performance lithium-ion anode made from self-assembled organic nanowires. By evaporating water on a copper current collector, we achieved a nanowire network without harmful solvents, enhancing lithium-ion diffusion and storage capabilities. The result? The self-assembled organic nanowire anode delivers a remarkable lithium storage capacity of […]
Our new paper, Electrochemical recycling of lithium-ion batteries: Advancements and future directions, is now available online at the Wiley journal EcoMat. Our review provides a perspective of different recycling techniques currently used for lithium-ion batteries. We begin by reviewing the more established pyrometallurgical and hydrometallurgical methods, which have been widely adopted in industrial applications. These […]
New paper published on cation separation during flow electrode capacitive deionization in Desalination. This work is about improving water treatment and resource recovery through selective ion removal using flow electrode capacitive deionization (FCDI). We explore separating specific cations like calcium and magnesium from multi-ion solutions, helping to optimize water desalination processes. Our data show that […]
Volker Presser delivers an invited (online) talk on “Electrode design of supercapacitors (and beyond)” at the 1st International Conference of Advanced Energy and Functional Materials Research (AEFM 2024) in Ilmenau, Germany.
New paper published in Nature Communication. This highly collaborative work (spearheaded by Dr. Gündoğ Yücesan) presents polyphosphonate covalent organic frameworks (COFs) constructed via P-O-P linkages, synthesized through a one-step condensation reaction. This process involves heating a hydrogen-bonded precursor made from phenylphosphonic acid and porphyrin, without chemical reagents. At temperatures above 210 °C, the COF transforms into […]
Two contributions from our team at the 38th Topical Meeting of the International Society of Electrochemistry (Nanomaterials in Electrochemistry): Volker Presser is giving an oral presentation with the title “MXene and hybrid electrodes for high performance energy storage” and Cansu Kök present a poster on “Continuous Lithium-Ion Extraction via Fuel Cell Desalination”.
Stefanie Arnold gives an oral presentation at the International Symposium on Beyond Li-Ion Batteries 2024 (BeLI24) in Padua, Italy. Her presentation has the title “Electrochemical perspectives for Lithium-ion battery recycling”
New paper published on “Life after death: Re-purposing end-of-life supercapacitors for electrochemical water desalination” in Batteries & Supercaps. Even the best supercapacitor, at some point, will reach its end-of-life. With limited amounts of precious elements (unlike lithium-ion batteries), elemental extraction of the active material’s components is not really attractive for supercapacitors. More interesting is to […]
New research paper from our collaboration with Michael Naguib: “Nitrogen-Doped Graphene-Like Carbon Intercalated MXene Heterostructure Electrodes for Enhanced Sodium- and Lithium-Ion Storage” published in Advanced Science. We’ve developed a novel N-doped graphene-like carbon intercalated Ti3C2Tx (NGC-Ti3C2Tx) heterostructure. But wait… why would one want to add something in-between the MX-layers, the wonderful interlayer space that should […]
New paper on solvation effects inside carbon nanopores during electrosorption published in Carbon. Our British-German study explores the solvation effects on ion adsorption and electrosorption within carbon micropores, employing nuclear magnetic resonance (NMR) spectroscopy to gain insights. Our data investigate how ionophilicity and ionophobicity – the tendency of ions to be uptaken by uncharged nanopores […]
