Designing Core–Shell Carbon Materials to Elucidate the Structure-Performance Relationship for Sodium Storage
One (re-)emerging research field is the ability of hard carbons (HCs) to reversibly store sodium ions. HCs are derived from pyrolysis of non-graphitizing precursors, typically carbonizable biomass, but often suffer from rather large irreversible capacity losses due to solid electrolyte interphase (SEI) formation during initial sodium insertion—even at low surface area.[1,2] Recent results indicate that […]

Challenges and opportunities in the wet processing of sulfide-based solid electrolytes for the cathode fabrication for solid-state lithium-ion batteries
Small-sized electrolyte particles are beneficial for the performance of solid-state batteries (SSBs), as they enhance the interconnection between the corresponding materials and thereby improve lithium-ion mobility, leading to reduced internal lithium-ion resistance. In this study, the comminution of commercial Li₆PS₅Cl argyrodite electrolyte was investigated under wet conditions in xylene using the dual centrifuge Delta Vita […]
Partial use of silicon in lithium-ion batteries with silicon-graphite composite electrodes to enormously increase lifetime
Increasing silicon (Si) contents in silicon-graphite (SiGr) blend anodes of lithium-ion batteries (LIBs) improve energy density but accelerate aging. Within SiGr-blend anodes, Si and graphite (Gr) act as two active materials connected in parallel, with Si predominantly (de-)lithiated at low full-cell states of charge (SOCs). Large-scale fleet studies show that real-world SOC usage in battery […]
Physics-based modeling of cyclic and calendar aging in Li-ion batteries with Silicon-Graphite composite anodes
For a growing electrification of society, batteries have to be improved regarding lifetime and energy density. To increase batteries’ energy density, new materials such as silicon with higher specific capacity are included, which also influence degradation behavior and impede longer battery lifetimes. Physics-based modelling of degradation processes is thereby inevitable to provide the underlying understanding […]

Battery system development based on Al-ion cell chemistry for grid stabilization applications
The demand for electrical energy and with that suitable storage solutions grow not only due to electromobility, but also due to the need to store and balance renewable energy. Those stationary applications are especially interesting for Li-free battery technologies, as requirements for energy density are less demanding, while costs and resources are more significant criteria. […]
Sustainable Energy Concepts For Battery Cell Production In North America
Why does the carbon footprint (CF) of a battery cell produced in Austin (TX, USA) exceed that of a bat-tery cell produced in St. Thomas (ON, Canada) by more than 100%, despite identical cell design, produc-tion processes, and materials? This example highlights the strong influence of location on the CF of bat-tery cell production and […]
Cradle-to-Use Life Cycle Assessment of Sodium-ion Batteries: The Role of Electricity Mix and Regional Production and Usage
Despite their lower energy density compared to Nickel Manganese Cobalt batteries, Lithium Iron Phosphate (LFP) batteries remain prevalent in electric vehicles due to their safety, longevity, and cost-effectiveness. Sodium-ion (Na-ion) batteries present an alternative, offering comparable energy density to LFP while potentially providing superior environmental benefits [1] [2]. Both technologies are central to the transition […]
