New paper on self-assembled organic nanowires for batteries and metal-ion supercapacitors published in Energy & Environmental Science
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 […]
New review paper published in EcoMat on electrochemical perspectives for lithium-ion battery recycling
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
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 presents work on electrode design at the AEFM conference
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 Communications
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 […]

New paper published in Batteries&Supercaps on upcycling of supercapacitor electrodes for water desalination
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 paper published on NGC-MXene in Advanced Science
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 […]
