![]() ![]() With the self-segregating structure, the room-temperature liquid metal batteries provided the promising solution for avoiding the self-discharge problem in conventional high-temperature liquid metal batteries. The room-temperature liquid metal batteries based on sodium–potassium (Na-K) alloy anode and Ga-based alloy cathodes were fabricated for the first time by Yu et al. Besides, no matter bending and stretching, the battery exhibited prominent performance during charging and discharging cycles. Owing to the natural deformability of electrode and electrolyte, the EGaIn-MnO 2 battery displayed improved electrochemical behaviors with increasing tensile strain. The EGaIn-MnO 2 battery achieved rechargeability for 100 cycles at 0.4 mA/cm 2 and 60 cycles at 1 mA/cm 2. fabricated rechargeable soft-matter EGaIn-MnO 2 battery for stretchable electronics for the first time, as shown in Fig. Though the rechargeable capacity of liquid metal-air battery was limited, this research laid the foundation for the soft and deformable batteries. Moreover, the deformability of the battery with light finger pressure made it possible to control the discharge-current. Such battery demonstrated excellent performance, such as high flexibility with bending radius less than 1 mm, high elasticity with 100% stretchability and excellent recovery with a discharge performance retention of 98.87% without electrochemical performance impairment. fabricated a cable-shaped liquid metal-air battery based on the EGaIn liquid anode, flexible gel electrolyte and carbon fiber based cathode, as shown in Fig. The Ga-based room-temperature liquid metal batteries were shown in Fig. Nowadays, reasonably increasing researches focused on the novel development and design of room-temperature liquid metal batteries. Hence, thermal management is of great importance for achieving higher efficiencies and the proper functioning of an LMB. These instabilities may cause spurious currents, hot spots, temperature gradients, short circuit as well as open circuit that can adversely affect the efficiency, operations, and life of an LMB. Even though LMBs have better thermal tolerance than conventional batteries, poor thermal management system often results in thermal instabilities. Therefore, thermal management is required to maintain LMB temperature in the desired range by using measures such as proper insulation, selection of suitable filling media in voids of LMB modules, controlling heater operation either manually or by controller intervention. The losses due to these resistances affect the temperature distribution inside an LMB. Charged metal ions face resistance to motion in the electrolyte and electrode layers as well as the electrode-electrolyte interfaces during the charging and discharging process. LMB involves electrochemical processes during operation (charging/discharging).
