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 […]

All-solid-state lithium-ion batteries (Li-ASSBs) exhibit superior safety and energy density relative to conventional liquid electrolyte-based cells. Sulfide-based solid electrolytes (SEs) demonstrate ionic conductivities approaching those of liquid electrolytes at ambient temperature [1], alongside low interfacial resistance owing to their compliant mechanical properties [2]. However, their intrinsically poor particle cohesion mandates incorporation of polymeric binders to […]

This study presents the development of a novel sodium cathode filament for Fused Filament Fabrication (FFF). The filament formulation utilized polylactic acid (PLA) as the polymer matrix and sodium vanadium phosphate (NVP) as the active material, with poly(ethylene glycol) dimethyl ether (PEGDME) and carbon black Super P added to enhance plasticity and conductivity. The optimal […]

We introduce a comprehensive yet simple and novel technical language processing (TLP) framework for digital battery passport (DBP) and other battery predictions, which combines the capabilities of artificial intelligence (AI) agents, large language models (LLMs), and optimized hard and soft prompts. Accurately estimating battery state in extreme temperatures is one of the challenges in the […]

The rapid expansion of lithium-ion battery (LIB) production to gigafactory scale has intensified the demand for more sustainable and cost-efficient manufacturing technologies. Within the cell production chain, electrode manufacturing remains a key innovation target, as conventional coating and drying processes substantially contribute to total cell costs and energy demand. The dry battery electrode (DBE) manufacturing […]

The increase in battery electric vehicles (BEVs) leads to a growing number of traction batteries reaching the end of their first life in the upcoming yeras. According to the European Battery Regulation (EU) 2023/1542, manufacturers are required to take back these batteries after vehicle use, raising the question of appropriate end-of-life strategies. Although batteries are […]

Sodium-ion batteries are receiving increasing attention as they offer a more sustainable and less critical energy storage solution than lithium-ion batteries. Furthermore, SIBs are considered a drop-in technology, paving the way for direct production in existing facilities and the application of the same characterisation techniques and equipment. In our efforts to scale up to pilot-plant […]

Lithium iron phosphate (LiFePO₄, LFP) is already recognized as a cathode material in lithium-ion batteries due to its excellent electrochemical stability, intrinsic safety, non-toxicity, and low cost. Beyond its established role in commercial battery systems, LFP is increasingly being explored as a reference electrode material for non-aqueous lithium-based electrochemical measurements because of its stable and […]

The electrolyte solution inside a battery plays a crucial role in both performance and longevity. Its volatile nature and limited quantity make it difficult to examine—especially in heavily aged commercial cells. This method focuses on such cells but is designed to be broadly compatible with other formats and future battery types. To analyze the electrolyte, […]
