Characterization of the influence of lithiophilic coatings on the performance of zero-excess solid-state batteries
The use of metallic lithium as an anode material has been the subject of intensive research for years, as it offers great potential for increasing energy density. The so-called zero-excess lithium metal battery (ZELMB), in which the anode is formed in situ during the charging step [1], makes it possible to achieve the theoretical maximum […]

OCV-ICA: Online diagnostics on reconstructed OCV curves from operational data
Li-ion batteries are more prone to fires than other battery technologies due to their inherent higher energy density as well as the flammability of especially electrode materials, separator, and electrolyte solvents. Ageing and degradation can contribute to considerably decrease the safety of a Li-ion battery, but the exact impact from ageing on safety of battery […]
Thermal-mechanical-electrochemical coupling in high-rate performance of large Li-ion cells
Because recycling processes have yet to be developed to a point where they are economically and environmentally viable, a feasible solution to their growing popularity is extending the useful lifetime and performance of Li-ion cells. This research uses experimentally parametrized physics-based modelling to understand how coupling among the charge, strain, and thermal history of a […]
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 […]
Assessing the Impact of Heterogeneous Pressure on the Lifespan of Lithium-Ion Battery Cells
The lifespan and performance of lithium-ion battery cells are highly dependent on cycling conditions, particularly mechanical stress. The relationship between stress and lifespan has gained significant attention in recent research (Li et al., 2022). But several key questions remain unresolved: • To what extent can a flexible compression system extend cell lifespan compared to conventional […]
Simulative Investigation of the Thermophysical Properties of Established and Novel Battery Materials
Intercalation batteries such as lithium‑ and sodium‑ion cells have become the preferred choice for mobile and stationary energy storage because of their high energy‑ and power‑density. Efficient thermal management is indispensable to keep the cells within the optimal performance window, to slow degradation mechanisms and to prevent thermal runaway. The intense market competition forces developers […]

Supercritical CO₂ Extraction from Battery-Recycling Effluents: Feasibility Study and Mechanistic Limits of Lithium Recovery
The treatment of battery-recycling effluents requires strategies that can both reduce contamination and enable the recovery of valuable materials. In this work, the feasibility of lithium recovery from a real semi-industrial battery-recycling process water was evaluated using supercritical CO₂ in combination with HTTA/TOPO chelation. The study followed a stepwise approach including baseline batch extraction, parameter […]
