This paper investigates the role of lithium squarate (Li₂C₄O₄) as a sacrificial additive for prelithiation in zero-excess lithium metal batteries (ZELMBs). These battery systems are attractive because they can achieve very high energy density by plating lithium directly onto a copper current collector during charging, eliminating the need for excess lithium metal. However, ZELMBs suffer […]

Management of the liquid alkali-metal in anodes of ZEBRA (sodium–nickel–chloride) or sodium-sulfur batteries is crucial for efficient cell design. Porous carbon materials can take up the liquid metal during battery charging and release it during discharge. Also, porous carbons provide a conductive framework at a low volume penalty even when the anode is stripped completely […]

Second-life lithium-ion batteries are increasingly considered for stationary energy storage and renewable integration. However, a major challenge in second-life deployment is the absence of reliable historical usage data. Key operating parameters such as cycle count and C-rate exposure are typically unknown, making accurate assessment of State of Health (SoH) and Remaining Useful Life (RUL) highly […]

Non-uniform in-plane current density distribution within current collectors is an intrinsic consequence of finite sheet resistance in large-format lithium-ion cells. It plays a key role in driving localized overpotentials, uneven electrochemical activity, and accelerated aging. Analytical models such as those derived by Wang et al. [1] predict that current spreading within single-sided tab configurations leads […]

Early detection of faults in lithium-ion batteries is essential to ensure the safety, reliability, and longevity of battery electric vehicles (BEVs). Fault mechanisms such as internal short circuits, lithium plating, electrolyte decomposition, and mechanical defects originate at the cell level and often develop unnoticed before manifesting as pack-level degradation or system failure. Detecting anomalies during […]

In operando / situ X-ray diffraction experiments of Lithium-Ion batteries are often carried out on synchrotron beam lines due to the availability of high brilliance sources and the possibility to use highly penetrating high-energy radiation. We show how a state-of-the-art laboratory diffractometer with a hard-radiation silver anode and hard-radiation optimized detector is used to quickly […]
