“…Moreover, the relatively low melting point of Li metal (i.e., 180 • C) is also a limiting factor for high-temperature applications [125]. Indeed, despite the critical effect of the electrolyte in terms of high volatility, flammability, and ambient temperature flash point [126], research works have focused on using more stable materials for studies above 100 • C (e.g., LiFePO 4 ) [127]. Use of conventional pseudo-reference electrode materials [26], such as Ag or Pt wire, is not recommended due to irreproducibility and drift of steady state potential, while alternative pseudo-reference electrodes such as Na metal have been investigated with only limited success [128,129].…”

Use of a reference electrode (RE) in Li-ion batteries (LIBs) aims to enable quantitative evaluation of various electrochemical aspects of operation such as: (i) the distinct contribution of each cell component to the overall battery performance, (ii) correct interpretation of current and voltage data with respect to the components, and (iii) the study of reaction mechanisms of individual electrodes. However, care needs to be taken to ensure the presence of the RE does not perturb the normal operation of the cell. Furthermore, if not properly controlled, geometrical and chemical features of the RE can have a significant influence on the measured response. Here, we present a comprehensive review of the range of RE types and configurations reported in the literature, with a focus on critical aspects such as electrochemical methods of analysis, cell geometry, and chemical composition of the RE and influence of the electrolyte. Some of the more controversial issues reported in the literature are highlighted and the benefits and drawbacks of the use of REs as an in situ diagnostic tool in LIBs are discussed.

“…This may be because the cutoff voltage did not reach the voltage plateau where the Cu current collector was dissolved. A shallow overdischarge may cause the battery to undergo charge-discharge cycles in a high-temperature environment exceeding 60 • C, and multiple cycles may degrade the battery capacity [28]. Moreover, under the coupled effects of overdischarge and a high temperature, more severe degradation occurs [29].…”

Overdischarge often occurs during the use of battery packs, owing to cell inconsistency in the pack. In this study, the overdischarge behavior of 2.9 Ah cylindrical NCM811 [Li(Ni0.8Co0.1Mn0.1)O2] batteries in an adiabatic environment was investigated. A higher overdischarge rate resulted in a faster temperature increase in the batteries. Moreover, the following temperatures increased: Tu, at which the voltage decreased to 0 V; Ti, at which the current decreased to 0 A; and the maximum temperature during the battery overdischarge (Tm). The following times decreased: tu, when the voltage decreased from 3 to 0 V, and ti, when the current decreased to 0 A. The discharge capacity of the batteries was 3.06–3.14 Ah, and the maximum discharge depth of the batteries was 105.51–108.27%. Additionally, the characteristic overdischarge behavior of the batteries in a high-temperature environment (55 °C) was investigated. At high temperatures, the safety during overdischarging decreased, and the amount of energy released during the overdischarge phase and short-circuiting decreased significantly. Shallow overdischarging did not significantly affect the battery capacity recovery. None of the overdischarging cases caused fires, explosions, or thermal runaway in the batteries. The NCM811 batteries achieved good safety performance under overdischarge conditions: hence, they are valuable references for battery safety research.

electronics and sensors mounted on drill bits to record geological data in the oil and gas industry need to be powered by batteries that operate in the temperature range from 60 to 120 °C and sometimes even up to 200 °C. [7] Additionally, the utilization of liquid electrolytes also makes it difficult to use lithium metal as an anode to further improve the energy density of lithium batteries, primarily due to lithium dendrite growth and active lithium consumption. [11,12] Because of these issues, alternative electrolyte materials are desired in order to meet the wide application demands of high temperature rechargeable lithium batteries. Solid polymer electrolytes are potential candidates for high temperature lithium battery electrolytes due to the absence of volatile liquid components. Poly(ethylene oxide) (PEO) is the most widely studied polymer electrolyte and has been shown anecdotally to work at up to 120 °C. [13] However, the cycling is not stable and the increased fluidity of PEO at such high temperature may lead to short circuit. [14,15] Other solid polymers have also been explored but none have shown stable cycling or adequate Coulombic efficiency above 100 °C.
