This review summarizes the state-of-art progress in electrode materials, separators, electrolytes, and charging/discharging performance for LIBs at low temperatures.
Modern technologies used in the sea, the poles, or aerospace require reliable batteries with outstanding performance at temperatures below zero degrees. However, commercially available lithium-ion batteries (LIBs) show significant performance degradation under low-temperature (LT) conditions.
In general, from the perspective of cell design, the methods of improving the low-temperature properties of LIBs include battery structure optimization, electrode optimization, electrolyte material optimization, etc. These can increase the reaction kinetics and the upper limit of the working capacity of cells.
However, commercially available lithium-ion batteries (LIBs) show significant performance degradation under low-temperature (LT) conditions. Broadening the application area of LIBs requires an improvement of their LT characteristics.
Here, we first review the main interfacial processes in lithium-ion batteries at low temperatures, including Li + solvation or desolvation, Li + diffusion through the solid electrolyte interphase and electron transport.
Two main approaches have been proposed to overcome the LT limitations of LIBs: coupling the battery with a heating element to avoid exposure of its active components to the low temperature and modifying the inner battery components. Heating the battery externally causes a temperature gradient in the direction of its thickness.
The increased resistance at low temperatures is believed to be mainly associated with the changed migration behavior of Li + at each battery component, including electrolyte, electrodes, and electrode-electrolyte interphases [21, 26].

This review discusses five distinct types of flexible batteries in detail about their configurations, recent research advancements, and practical applications, including flexible lithium-ion batter.
As the market demand for wearable technologies continues to grow, the future of flexible batteries is promising, and further advances are likely. As with all batteries, one hurdle to overcome is their safe disposal and recycling, which should come as the technology and associated applications become circular.
Compared with traditional batteries, flexible batteries have great advantage in resistance to mechanical deformation, which enable electronic products perform well in a variety of conditions. More application scenarios are envisioned with the development of flexible batteries.
Compared with flexible batteries, stretchable batteries need to bear more serious deformations, including stretching and twisting, which require the electrodes for stretchable batteries to possess even better mechanical properties [11, 87].
Reliable integration technologies are the determinant for the advancement of flexible batteries. Although the breakthroughs have been achieved in fundamental theory and key materials, there is still a need for further advancements in integration technologies.
Compared to conventional rigid batteries configurations, the energy density of flexible batteries is significantly reduced due to the inclusion of a substantial amount of electrochemically inactive materials necessary for ensuring the flexibility of the batteries.
The rapidly escalating development of wearable devices, flexible electronics and bendable displays demands power sources that match the agility of these systems. Standard, rigid batteries may soon be a thing of the past as thin, flexible batteries – made of lightweight materials that can be easily twisted, bent or stretched – reach the market.
