Energy Technology is an applied energy journal covering technical aspects of energy process engineering, including generation, conversion, storage, & distribution. Herein, a room-temperature liquid metal battery (LMB) with a solid lithium anode electrode and gallium–tin (Ga–Sn) alloy cathode electrode is reported.
Lithium-ion batteries with both low-temperature (low-T) adaptability and high energy density demand advanced cathodes. However, state-of-the-art high-voltage (high-V) cathodes still suffer insufficient performance at low T, which originates from the poor cathode–electrolyte interface compatibility. Herein, we developed a shallow surface …
Low-temperature electrolytes (LTEs) have been considered as one of the most challenging aspects for the wide adoption of lithium-ion batteries (LIBs) since the SOA electrolytes cannot sufficiently support the redox reactions at LT resulting in dramatic performance degradation. Although many attempts have been taken by employing various …
Lithium metal batteries face problems from sluggish charge transfer at interfaces, as well as parasitic reactions between lithium metal anodes and electrolytes, due to the strong electronegativity of oxygen donor solvents. These factors constrain the reversibility and kinetics of lithium metal batteries at low temperatures. Here, a …
Among various rechargeable batteries, the lithium-ion battery (LIB) stands out due to its high energy density, long cycling life, in addition to other outstanding properties. However, the capacity of LIB drops dramatically at low temperatures (LTs) below 0 °C, thus restricting its applications as a reliable power source for electric vehicles …
Abstract. Dendrite growth of lithium (Li) metal anode severely hinders its practical application, while the situation becomes more serious at low temperatures due to the sluggish kinetics of Li-ion diffusion. This perspective is intended to clearly understand the energy chemistry of low-temperature Li metal batteries (LMBs).
Lithium batteries have been widely used in various fields such as portable electronic devices, electric vehicles, and grid storages devices. However, the low temperature-tolerant performances (−70 to 0 C) of lithium batteries are still mainly hampered by low ionic ...
The drop in temperature largely reduces the capacity and lifespan of batteries due to sluggish Li-ion (Li +) transportation and uncontrollable Li plating behaviors. Recently, attention is gradually paid to Li metal batteries for low-temperature operation, where the explorations on high-performance low-temperature electrolytes emerge as a …
Similarly, −20 C is found to be the optimal storage temperature for cells stored at 0.5 SOC, and only 0.005 mAh capacity is lost after 10 h (Fig. 2 a and S3). For cells with 1 SOC, the self-discharge rate is smaller with decreasing storage temperature (Fig. 2
