Summary: This study reviews the current state-of-the-art self-heating methods and proposes the heating triangle as a new quantitative indicator for comparing self-heating methods. The heating triangle considers three fundamental metrics: specific heating rate, coefficient of performance, and specific temperature difference, enabling a quantitative assessment of self-heating methods. The analysis shows that similar metrics are observed for the same type of self-heating method, supporting the universality of the proposed indicator. The proposed heating triangle provides a standardized approach to compare heating methods and drive innovation.

Summary: Energy storage devices have made significant advancements in recent years, but their performance is limited in low-temperature environments. Developing new cathode materials is a key strategy to alleviate these limitations, with lithium-ion batteries being the most attractive option. Sodium-ion batteries, magnesium-ion batteries, and zinc-ion batteries are potential substitutes, but they face their own challenges at low temperatures. This review provides an overview of these batteries and their high-energy cathode materials that can operate in low-temperature environments.

Summary: As lithium-ion battery (LIB) research shifts towards high energy density and fast charging batteries, traditional assumptions about battery thermal management around room temperature may not hold true. A comprehensive review of thermal considerations for LIBs targeting high energy density and fast charging is necessary, including optimal thermal conditions, heat transport and generation inside the battery, and thermal management strategies. To maintain temperature uniformity and prevent excessive internal temperature rise, enhancing heat transfer inside the battery and reducing thermal contact resistance between electrodes can significantly improve the effective thermal conductivity of batteries.

Summary: This research investigates the impact of heating temperature on the thermal runaway (TR) of lithium-ion batteries (LIBs). It is found that TR occurs when the heating temperature exceeds 200 degrees Celsius, while only safety venting is observed at 175 degrees Celsius. As the heating temperature increases, the time interval between safety venting and TR decreases, and the temperature difference within the battery decreases. Additionally, the contribution of self-generated heat to trigger TR at different heating temperatures is identified.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

Summary: By coupling electrochemical testing to operando synchrotron based X-ray absorption and powder diffraction experiments, blended positive electrodes consisting of LiMn2O4 spinel (LMO) and layered LiNi0.5Mn0.3Co0.2O2 (NMC) were studied to understand their redox mechanism. It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
