In the realm of low-altitude flight power systems, such as electric vertical take-off and landing (eVTOL), ensuring the safety and optimal performance of batteries is of utmost importance. Lithium (Li) plating, a phenomenon that affects battery performance and safety, has garnered significant attention in recent years. This study investigates the intricate relationship between Li plating and the growth profile of cell thickness in Li-ion batteries. Previous research often overlooked this critical aspect, but our investigation reveals compelling insights. Notably, even during early stage of capacity fade (~ 5%), Li plating persists, leading to a remarkable final cell thickness growth exceeding 20% at an alarming 80% capacity fade. These findings suggest the potential of utilizing cell thickness growth as a novel criterion for qualifying and selecting cells, in addition to the conventional measure of capacity degradation. Monitoring the growth profile of cell thickness can enhance the
Anode-free sodium metal batteries (AFSMBs) with initial zero sodium anodes are promising energy-storage devices to achieve high energy density and low cost. The morphology and reversibility of sodium controls the cycling lifespan of the AFSMBs, which is directly affected by the separator. Here, we compared the sodium deposition and corresponding electrochemical behaviors under the influence of three commercial separators, which were Celgard 2500, Al2O3-coated PP separator and glass fiber (denoting as 2500, C-PP and GF). Firstly, the reversibility of sodium plating/stripping was tested using half-cells, where coulombic efficiencies were stable at ~99.89% for C-PP and GF compare to 99.65% for 2500, indicating more dead sodium were formed for 2500. Then, the morphologies of deposited sodium were compared using optical microscopy. Compared to inhomogeneous sodium growth under 2500, C-PP obtained more flatter sodium layer with less height difference, attributing to the high mechanical

With the worldwide trends in mobile electrification, consumers' demand for fast charging of electric vehicles (EVs) continues to grow. However, due to the defects of the current mainstream vehicle-mounted lithium-ion batteries (LIBs), lithium plating will occur at the anode during charging at high current rates, reducing battery life and even causing serious safety problems. In this paper, a pseudo two-dimensional (P2D) model integrated with lithium plating and SEI growth reaction is established to simulate the aging behavior of the battery during the cycle aging process. After verifying the model, we set up simulation conditions to quantitatively analyze the relationship between battery operating temperature, charging rate and cycle life, as well as the causes of capacity attenuation under each operating condition. By analyzing the simulation results, we found that lithium deposition can be predicted based on the overpotential, which can provide guidance for healthy and efficient fast

Currently, two materials are used as anodes in most commercially available lithium-ion batteries that power items like cellphones, laptops, and electric vehicles. The most common, a graphite anode, is extremely energy dense — a lithium-ion battery with a graphite anode can power a car for hundreds of miles without needing to be recharged; however, recharging a graphite anode too quickly can result in fire and explosions due to a process called lithium metal plating. A safer alternative, the lithium titanate anode, can be recharged rapidly but results in a significant decrease in energy density, which means the battery needs to be recharged more frequently.
