“…Hu et al. [ 197 ] reported a binder‐free LTO electrode with aligned CNT nanosheets and Ag decorating. Benefiting from the high exposed surface area of LTO (aligned CNT nanosheets replaced the conventional binder) and low solvation energy for Li + with DIOX‐based electrolyte, LTO delivered a reversible capacity of 140 mAh g −1 at 0.2 C and −60 °C, corresponding to 85% of its RTC.…”

With the highest energy density ever among all sorts of commercialized rechargeable batteries, Li‐ion batteries (LIBs) have stimulated an upsurge utilization in 3C devices, electric vehicles, and stationary energy‐storage systems. However, a high performance of commercial LIBs based on ethylene carbonate electrolytes and graphite anodes can only be achieved at above −20 °C, which restricts their applications in harsh environments. Here, a comprehensive research progress and in‐depth understanding of the critical factors leading to the poor low‐temperature performance of LIBs is provided; the distinctive challenges on the anodes, electrolytes, cathodes, and electrolyte–electrodes interphases are sorted out, with a special focus on Li‐ion transport mechanism therein. Finally, promising strategies and solutions for improving low‐temperature performance are highlighted to maximize the working‐temperature range of the next‐generation high‐energy Li‐ion/metal batteries.

“…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.

storage technology, have pervaded practically all portable devices and electric vehicles in the 21st century, and it has been given considerable attention for increased roles in aerospace. [6] However, conventional LIBs have been reported to lose ≈88% of their room-temperature capacity (RTC) at −40 °C. [7] For instance, Panasonic 18650 batteries were tested in 2001 and found to have power and energy density of ≈800 W L −1 and ≈100 Wh L −1 at 25 °C, but only retained ≈1.25% and ≈5% at −40 °C. [8] Numerous approaches have been put forth in recent years to deal with this problem, including thermal management, electrode material optimization as well as electrolyte engineering (Figure 1).
