Lithium-Ion Battery Systems, Thermal Management, and Recycling
This community focuses on the engineering, safety, and lifecycle management of lithium-ion batteries, specifically addressing thermal control, state estimation, and the recovery of materials from spent cells.
The work centers on three interconnected technical challenges: thermal management to prevent runaway, accurate state-of-charge and health estimation for grid and vehicle integration, and the chemical extraction of lithium, cobalt, and nickel from end-of-life batteries. Recurring methods include deep eutectic solvents for leaching, phase-change materials for heat dissipation, and physics-informed neural networks for degradation modeling. Applications range from electric vehicle battery packs to stationary energy storage systems, with a strong emphasis on life-cycle assessment and circular economy principles.
The largest share of the community's output is found in lithium research, accounting for 15.6% of all tracked lithium studies, and 17,285 papers here. Manganese and cobalt also feature prominently, each representing roughly 3.1% of their respective element research.
The community comprises 49,318 papers, publishing most frequently in the Journal of Energy Storage, Journal of Power Sources, and Hydrometallurgy.
Recent work continues to prioritize state-of-health estimation using acoustic emission signals and machine learning, alongside experimental studies on immersion cooling for commercial energy storage and the development of lithium sieves for extracting lithium from low-quality brines.
