Summary: In this study, temperature data were collected using optical fiber Bragg grating sensors placed inside commercial pouch cells, allowing for monitoring the heat release during the formation cycles and real-driving cycling. The research provides insights into the contribution of the anode and the impact of additives on overall heat generation, as well as a comparison of the heat generation of NMC-based batteries under varying power and voltage levels. Continuous monitoring of battery heat release throughout its lifespan enhances our understanding of interconnected materials surfaces and electrolyte reactions.

Summary: Synchrotron X-ray diffraction computed tomography (XRD-CT) technique was used to study the behavior of a commercial cylindrical NCA battery. The analysis revealed multiple chemical heterogeneities related to the distribution of lithium in both the cathode and the anode. The charging process showed varying degrees of activity in the anode, while the specific cell geometry resulted in inactive-to-lithiation regions. Additionally, the aluminum tab had a negative impact on the cathode in direct contact with it.

Summary: This study investigates the aging-induced degradation of commercial Li-ion pouch cells with lithium nickel-manganese-cobalt-oxide-based cathodes and graphite anodes under various operating conditions. The research develops a detailed equivalent electrical circuit model and validates it using in situ electrochemical impedance spectroscopy. The study confirms the dependence of the cells' capacity fade on factors such as temperature and state-of-charge, and highlights the unusual finding that cells held at 95% state-of-charge exhibit lower degradation than those at 70%. The research introduces a high performing calendar aging model that can be useful for battery management systems.

Summary: This paper demonstrates the feasibility of using fiber Bragg grating sensors to monitor the thermal evolutions of commercial lithium-ion batteries during long-term cycling ageing and decodes the evolution of entropy and overpotential heat rates using delicate heat deconvolution. Moreover, it computes high-resolution enthalpy profiles from operando heat and voltage profiles to track and unravel redox variations during cycling ageing.

Summary: The benefits of using high-entropy ceramics in Li-ion technology have been well-documented. This study provides a comprehensive model explaining the stable electrochemical performance of a multicomponent solid solution-type material. The material exhibits high specific capacity and excellent capacity retention, with stability stemming from the reversible reactivity of the amorphous matrix and the high level of cation disorder at the atomic scale.

Summary: Li-ion batteries are widely used in planetary missions by NASA, with a growing interest in commercial 18650 cells due to their advantages over custom large-format cells. Commercial 18650 cells offer higher specific energy and energy density, enhanced safety and reliability, modularity and redundancy in design, and simpler charging methods, making them a viable option for space applications. Multiple high-quality manufacturers provide 18650 cells with specific energy around 250 Wh/kg and power density around 2 kW/kg, showing promising performance for extensive space-qualification prior to implementation in space missions.

Summary: A high surface area Li metal anode with ZnO nanorod-decorated Ni foam scaffold was created, achieving a 10x improvement in rate capability compared to traditional designs. The ZnO nanorods enhance Li metal wettability and promote uniform Li nucleation, enabling the RFB to be operated with a prelithiated or Li-less discharged anode. The use of redox mediators allows for the oxidation and reduction of solid S particles, demonstrating a respectable energy density of 20.3 Wh L-1.

Summary: This study addresses the challenges of fast charging lithium-ion batteries at low temperatures. It found that most batteries have reduced fast charging capabilities at lower temperatures. The study identified the five best-performing batteries at different temperatures and analyzed their performance. It also found that the abnormal growth of the anode solid electrolyte interphase (SEI) leading to lithium inventory loss is the main cause of performance decay and cell failure.

Summary: The use of solid electrolytes in lithium batteries shows promise for increasing power and energy density. However, challenges such as capacity-fading remain, with chemical, electrochemical, and chemo-mechanical effects being identified as causes. A model was proposed to interpret low-frequency impedance of the cathode, and an electrochemical technique was developed to determine the active mass in the cathode. The study demonstrated that chemo-mechanical evolution in the composite cathode is the main cause for cell capacity fading.

Summary: The post-mortem analysis of commercial 18650 lithium-ion cells after long-term cycling reveals that the main capacity loss is caused by the degradation of the positive cathode rather than the negative graphite anode. The cathode degradation is attributed to a combination of effects including mechanical damage, particle cracking, and crystallographic changes.
