“…As shown in Table 4, it can be seen that the resistance of the copper-aluminum ISC was much smaller than that of the aluminum-negative ISC. As a result, a fusing phenomenon could occur for the copper-aluminum ISC [33], which was not considered in the simulation investigated in this paper. Figure 2 shows the thermal responses under different ISC types for the Li-ion battery at SOC = 0.2 and r in = 0.5 mm.…”

Current studies on the mechanical abuse of lithium-ion batteries usually focus on the mechanical damage process of batteries inside a jelly roll. In contrast, this paper investigates the internal short circuits inside batteries. Experimental results of voltage and temperature responses of lithium-ion batteries showed that battery internal short circuits evolve from a soft internal short circuit to a hard internal short circuit, as battery deformation continues. We utilized an improved coupled electrochemical-electric-thermal model to further analyze the battery thermal responses under different conditions of internal short circuit. Experimental and simulation results indicated that the state of charge of Li-ion batteries is a critical factor in determining the intensities of the soft short-circuit response and hard short-circuit response, especially when the resistance of the internal short circuit decreases to a substantially low level. Simulation results further revealed that the material properties of the short circuit object have a significant impact on the thermal responses and that an appropriate increase in the adhesion strength between the aluminum current collector and the positive electrode can improve battery safety under mechanical abusive conditions.

Conventional lithium‐ion batteries (LIBs) are constantly evolving to improve their electrochemical performance and safety. In the past decade, research on electrode and electrolyte materials has significantly promoted the development of conventional LIBs. However, the current collector (CC) in conventional LIBs has not received sufficient attention. As a transfer unit that collects and disperses electrons from electrodes and transports them to the load, the performance of the CC significantly affects the performance of LIBs. This article reviews the impact of the CC on the electrochemical performance and safety of conventional LIBs in four aspects: CC requirements, manufacturing process, surface coating modification, and multifunctionalized CCs. Meanwhile, this review provides an objective summary and prospect on the transition from single‐functionality to multifunctionality requirements for CC, as well as the future needs for CC development and the technical hurdles that should be overcome. The article focuses on providing a detailed insight into the important impact of CCs on conventional LIBs, which has not received enough attention in the past. It emphasizes the need and urgency for the development of multifunctional CCs to provide new ideas for improving the performance of conventional LIBs.

Summary Internal short circuit (ISC) of lithium‐ion battery is one of the most common reasons for thermal runaway, commonly caused by mechanical abuse, electrical abuse and thermal abuse. This study comprehensively summarizes the inducement, detection and prevention of the ISC. Firstly, the fault tree is utilized to analyze the ISC inducement, including the abuse conditions, improper manufacture and design defects. Secondly, the ISC substitute triggering methods (utilizing mechanical deformation from the outside or utilizing controllable components introduced inside) are summarized considering the randomness of ISC, which have high repeatability. Moreover, these methods can be used to investigate the evolution and the hazard boundary of ISC. The ISC severity is determined by the ISC type, ISC location, ISC area, battery state of charge, capacity, material and structure. There are four types of ISC mode, the danger extends ranking is aluminum‐anode > aluminum‐copper > cathode‐copper > cathode‐anode. The ISC evolution is presented based on the upper summary. Then, the ISC detection methods are reviewed: (1) comparing the measured data with the predicted value from the model; (2) detecting whether the battery has self‐discharge; (3) comparing based on the battery inconsistency and (4) other signals. Finally, the prevention strategies are summarized, which can be used to reduce the ISC risk by blocking electron or lithium‐ion channels in the battery cell.
