... + 0.15 TO electrolyte cycled stably for >200 cycles at room temperature with 80% capacity retention. The as-assembled ALB cell after undergoing hot formation (40 °C) at initial cycles, exhibited extraordinary safety performance when operated under a cell pressure of 1.2 MPa respectively [90]. Similarly, the effect of LNO additive in a reduced concentration of tetraethylene glycol dimethyl ether (TEGDME) electrolyte was studied, where the half-cell configuration 2M of LiTFSI improved the C.E. due to the stability conferred by the Li 2 O to the SEI during cycling [91]. ...

High-heat transfer lithium-ion batteries: A new era in battery thermal management

... Lithium-ion batteries (LIBs) are currently the most ideal options, offering an energy density of ~ 250 Wh/kg [5][6][7][8] . However, further advancements are urgently needed to extend the cruising range of these applications [9][10][11][12][13] . Recently, rechargeable lithium-chlorine batteries using thionyl chloride (SOCl 2 ) as the electrolyte, Li metal as the anode, and porous materials as the cathode have gathered much attention due to their high theoretical energy density [14][15][16][17][18][19][20][21][22][23] . ...

Ion Flux Optimization via Hollow Carbon Nanoreactors for High-Power and Energy-Dense Li-Cl2 Batteries

... A larger single sheet foil area, A foil , directly leads to a reduction in the internal resistance of a single electrochemical sandwich, and a greater shorting current. Further, it has previously been demonstrated that a larger nail diameter, D nail , leads to more global heating, due to its larger thermal mass to absorb I 2 R short heating and an enhanced ability to reject heat axially through the nail (Shaffer et al., 2012;Kalupson et al., 2014;Zhao et al., 2015a). Generally speaking, for a given cell internal structure (electrode thicknesses, porosities, etc.), A foil and D nail largely determine the locality (global, local, or mixed) of the heating, and a greater cell capacity accentuates the local or global nature of the heating, simply by having greater energy to be dissipated during the short. ...

... The high use of lithium-ion cells (LIBs) in various mobile equipment [1] and, in particular, in the development and commercial implementation of electrical cars [2,3] has made this technology progress rapidly in recent years, becoming the predominant choice in terms of rechargeable batteries. Besides their intense use for consumer electronics and electrical cars, LIBs have also been employed intensively in energy storage systems [4], grid services [5,6], UPS systems [7], electrified aviation [8,9], and even in tailored designed batteries for aerospace [10] or military applications [11]. In comparison with similar rechargeable technologies, such as nickel-cadmium, nickel-metal-hydride, or lead-acid types, lithium-ion cells (LIBs) have some particular advantages. ...

... FF-E exhibits lower HFR compared to FF-B and this difference is more pronounced at low RH conditions. The observed outcomes are in accordance with the deeper cathode channels of FF-E, which results in a lower gas velocity and thus in an increased water retention [22,67]. This phenomenon is particularly notable at low RH gas reactants, where the increased water retention significantly enhances membrane hydration and consequently increases ion conductivity [68], leading to the differences in results observed in Fig. 11a. ...
