“…On the other hand, the compromised energy/power density and cyclability of the cell model at low temperatures is always due to the insufficient dynamics at the anode|electrolyte interface, which resulting in dendritic Li plating. [42,43] As shown in Figure 5f, the NCM811|Li cell with MS|PE|Ag 2 S separator demonstrates the reduced overall impedance value of 161.7 Ω as compared to the cell with PE separator (783.3 Ω) and MS|PE separator (535.0 Ω) at 0 °C. From the equivalent circuit simulated from EIS fittings (Table S1, Supporting Information), the interfacial resistance (R int ) of the NCM811|MS|PE|Ag 2 S |Li cell (157.3 Ω) is obviously lower than those of the cells with PE separator (779.7 Ω) and MS|PE separator (531.7 Ω).…”

solutions, explorative studies of the electro-redox couples, with the concurrent high retrievable capacity, enlarged nominal voltage gap, and rapid reaction kinetics, hold the key to promote the energy-dense battery construction at the extreme power output. [1] For the lithium ion batteries, the energy densities of traditional formats (LiCoO 2 /LiFePO 4 cathodes and graphite anodes) have approached their theoretical limits. [2] Alternatively, the unit cell prototyping of the high-capacity Li metal anode with the nickel-rich cathode can achieve the enhanced level of energy densities at the device level. [3,4] When soaking this electrode couples in the conventional carbonate-based electrolytes, however, the Fermi-energy incompatibility at the multiscale interface would cause the uncontrollable dendrite growth on the metallic foil and cathode structure collapse upon the high-voltage cycling. [5] Therefore, the reliable operation of the energy-dense battery necessitates the harmony balance of the enlarged voltage gap and the interfacial stability at multiple scales, yet still remains challenging.As the most attractive cathode type of the practical relevance, nickel-rich (Ni content >0.8) layered oxides exhibit the merits of the large specific capacity (>200 mAh g −1 ), environmental benignity and relative lower cost as compared to the LiCoO 2 cathode. Despite of the dominant nickel occupancy in the layered oxides for elevating the Li storage sites, the increased nickel ratio adversely deteriorates the cycle performance. The transition metal (TM) layer of the oxide structure at the highvoltage charged states would oxidize the carbonate solvents in the presence of moisture, leading to serious self-discharge rates upon the high-temperature storage. [6] Additionally, the hydrofluoric acid (HF) formed by the decomposition of the lithium hexafluorophosphate (LiPF 6 ) salt aggravates the TM ions (Co 2+ , Ni 2+ , and Mn 2+ ) dissolution and structural collapse of the layered cathode, meanwhile the TM species would deposit on the anode surface and degrade the solid electrolyte interface (SEI). [7] So far, a plethora of mitigation strategies were implemented to insulate the direct contact of the oxide particles with the electrolyte, for instance the exquisite coatings with The reliable operation of Li metal batteries suffers from cathode collapse due to high-voltage cycling, interfacial reactivity of the Li deposits, self-discharge at the elevated temperatures, as well as the power output deterioration in low-temperature scenarios. In contrast to the individual electrode optimization, herein, a hetero-layered separator with an asymmetric functional coating on polyethylene is proposed in response to the aforementioned issues: On the face-to-cathode side, the hybrid layer of the molecular sieve and sulfonated melamine formaldehyde can scavenge the hydrofluoric acid and moisture residues from the carbonate electrolyte, maintaining the cathode robustness in both the high-voltage cycling or high-temperature storage scenarios; while...

“…On the other hand, to deeply research the relationship between nanostructure and performance, it is appropriate to fabricate other control samples in the future. In addition, it is worth mentioning that the improvement of low-temperature performance is very important for next-generation LIBs [ 38 ]; furthermore, size reduction, doping, and surface modification are potential methods for enhancing the low-temperature performance of electrodes [ 39 , 40 ]. Hence, it is reasonable to consider that many efforts should be made to the controlled synthesis of CoSeO 3 ‧2H 2 O with other morphologies, heteroatoms doped CoSeO 3 ‧2H 2 O, and CoSeO 3 ‧2H 2 O@C composites.…”

As novel anodic materials for lithium-ion batteries (LIBs), transitional metal selenites can transform into metal oxide/selenide heterostructures in the first cycle, which helps to enhance the Li+ storage performance, especially in terms of high discharge capacity. Herein, well-defined hierarchical CoSeO3‧2H2O nanoflowers assembled using 10 nm-thick nanosheets are successfully synthesized via a facile one-step hydrothermal method. When used as anodic materials for LIBs, the CoSeO3‧2H2O nanoflowers exhibit a considerably high discharge capacity of 1064.1 mAh g−1 at a current density of 0.1 A g−1. In addition, the obtained anode possesses good rate capability and cycling stability. Owing to the superior electrochemical properties, the CoSeO3‧2H2O nanoflowers would serve as promising anodic materials for high-performance LIBs.

“…These flaws combine to cause severe polarization and poor electrochemical activity in electrode materials at low temperatures, resulting in rapid capacity fading of electrodes during charge-discharge cycles. 30 Moreover, during low-temperature charging, particularly at high rates, the anode is more likely to precipitate Li metal, exacerbating the irreversible reaction with the electrolyte and causing the cell polarization to grow once more. Gradually, the battery's performance deteriorates even further.…”

Lithium-ion batteries (LIBs) have become well-known electrochemical energy storage technology for portable electronic gadgets and electric vehicles in recent years. They are appealing for various grid applications due to their characteristics such as high energy density, high power, high efficiency, and minimal self-discharge. LIBs may now theoretically be tailored for a variety of operating circumstances and applications because of the ability to change the material properties of the electrodes and electrolytes. However, LIBs operating at low temperatures have significantly reduced capacity and power, or even do not work properly, which poses a technical barrier to market entry for hybrid electric vehicles, battery electric vehicles, and other portable devices. This review summarizes the state-of-art progress in electrode materials, separators, electrolytes, and charging/discharging performance for LIBs at low temperatures. Due to the sluggish kinetics, insufficient ionic conductivity at low temperatures, and sluggish desolvation, it became challenging to enhance the electrochemical performance of LIBs at reduced temperatures. This review recommends approaches to optimize the suitability of LIBs at low temperatures by employing solid polymer electrolytes (SPEs), using highly conductive anodes, focusing on improving commercial cathodes, and introducing lithiumrich materials into separators. Finally, we propose an integrated electrode design strategy to improve low-temperature LIB performance.
