“…Meanwhile, the LiPF 6 -derived byproducts also deteriorate the crystallinity of electrodes, and current collectors, increase the cell impedance, eventually resulting in battery failure. Several functional electrolyte components or additives, e.g., vinylene carbonate (VC), [7,25] 1,2-bis (difluoromethylsilyl) ethane (FSE), [26] and fluoroethylene carbonate (FEC) [27,28] have been used to overcome the thermal decomposition. Low concentrations of these compounds can generate protective layers over the electrode materials.…”

“…[28,43] EC/PC mixtures have been used as solvents due to their high boiling point (>200 °C) and excellent flame resistance. Kohlmeyer et al [7] developed a unique nanocomposite membrane with an HT electrolyte (Pyrolux/HT) capable of operating over a wide temperature window (20-120 °C). The membrane was based on a printable and flexible Al 2 O 3 -poly(vinylidene fluoride) separator infiltrated by an EC/PC mixture solvent.…”

self-discharge rates. [1-3] LIBs permeate nearly every aspect of human life. They are widely used in portable electronics (e.g., smartphones, smart-watches, and laptops), transportation (e.g., electric and hybrid vehicles), and biomedical applications (e.g., cardiac pacemakers and cochlear implants). In light of these achievements, J.B. Goodenough, M.S. Whittingham, and A. Yoshino won the 2019 Nobel prize in chemistry. [4] Despite the considerable success of conventional LIBs, their operational regime is typically around room temperature (RT). Operating at low (<0 °C) or high (>60 °C) temperatures usually deteriorate the performance and leads to safety risks. [5] We should also note that commercial LIBs are highly hazardous as they can ignite and explode in case of an accident, overheating, and overcharging, requiring more stringent safety standards, e.g., wide temperature operability and nonflammability. For example, electric vehicles require battery systems that can deliver a stable performance while maintaining a high energy density even in extreme climates, such as cold mountainous areas, where the temperatures can be as low as −40 °C, and hot deserts, where equipment exposed to sunlight can reach temperatures exceeding 70 °C. [6] Moreover, task-specific applications call for reliable energy storage solutions at extreme temperatures, including subsurface exploration (such as for mineral, oil, and gas), aerospace engineering, safety and rescue, and sterilizable medical devices. [2] Conventional LIBs are composed of a positive electrode or cathode (e.g., LiFePO 4 (LFP), LiNi x Mn y Co z O 2 (x + y + z = 1, NMC) and LiCoO 2 (LCO)), an electrolyte (including solvents, Li salts, and additives), a separator (typically a polyolefin membrane), and a negative electrode or anode (e.g., graphite and Li 4 Ti 5 O 12 (LTO)). Generally, the electrode materials are nonflammable and thermal stable (>300 °C). While the polyolefin membrane will melt/shrink over 120 °C, the commercial separators composited with ceramic nanoparticle (e.g., SiO 2 and Al 2 O 3) have been developed to reduce thermal shrinkage when exposed to overheating. [7,8] Therefore, the major challenge of commercial LIBs at extreme operating temperatures comes to the electrolyte. Carbonates are commonly used as solvents for conventional LIB electrolytes. However, these compounds are Li-ion batteries (LIBs) are the energy storage systems of choice for portable electronics and electric vehicles. Due to the growing deployment of energy storage solutions, LIBs are increasingly required to function safely and steadily over a broad range of operational conditions. However, the conventional electrolytes used in LIBs will malfunction when the temperatures fall below zero or elevate above 60 °C. Further, conventional electrolytes are toxic and flammable, leading to severe safety risks, especially in the case of an accident or overheating. Therefore, an ever-growing body of research has been dedicated to the development of electrolytes characterized by high ionic conduct...

Reports of recent fire accidents in the electronics and electric vehicles (EVs) industries show that thermal runaway (TR) reactions are a key consideration for the industry. Utilization of solid electrolytes (SEs) could be an important solution in to the TR issues connected to exothermic electrochemical reactions. Data on the thermal stability of modern SEs, ionic transport mechanisms, kinetics, thermal models, recent advances, challenges, and future prospects are presented in this review. Ceramic polymer nanocomposites are the most appropriate SEs for high‐temperature stable batteries (in the range of 80–200 °C). Hydrogels and ionogels can be employed as stable, flexible, and mechanically durable SEs for antifreeze (up to –50 °C) and high‐temperature (up to 200 °C) applications in supercapacitors. Besides the thermal safety features, SEs can also prolong the lifecycle of energy storage devices in next‐generation EVs, space devices, aviation gadgets, defense tools, and mobile electronics.

The advancement and popularity of smartphones have made it an essential and all-purpose device. But lack of advancement in battery technology has held back its optimum potential. Therefore, considering its scarcity, optimal use and efficient management of energy are crucial in a smartphone. For that, a fair understanding of a smartphone's energy consumption factors is necessary for both users and device manufacturers, along with other stakeholders in the smartphone ecosystem. It is important to assess how much of the device's energy is consumed by which components and under what circumstances. This paper provides a generalized, but detailed analysis of the power consumption causes (internal and external) of a smartphone and also offers suggestive measures to minimize the consumption for each factor. The main contribution of this paper is four comprehensive literature reviews on: 1) smartphone's power consumption assessment and estimation (including power consumption analysis and modelling); 2) power consumption management for smartphones (including energy-saving methods and techniques); 3) state-of-the-art of the research and commercial developments of smartphone batteries (including alternative power sources); and 4) mitigating the hazardous issues of smartphones' batteries (with a details explanation of the issues). The research works are further subcategorized based on different research and solution approaches. A good number of recent empirical research works are considered for this comprehensive review, and each of them is succinctly analysed and discussed.
