“…Potassium ions have a higher standard redox potential than that of Li ions, and thus can effectively suppress Li dendrite growth through electrostatic attraction. Ye et al reported a positively charged electrostatic shield effect upon adding aluminum chloride (AlCl 3 ) to 1.0 m lithium hexafluorophosphate (LiPF 6 )‐ ethylene carbonate (EC)/dimethyl carbonate (DMC)/diethyl carbonate(DEC) electrolyte . Different from Cs + , aluminum ions did not directly accumulate around the lithium protuberances.…”

“…Therefore, Cs + will be absorbed at the tips of Li deposition and form a positively charged electrostatic shield to force subsequent Li ions to adjacent regions avoiding the self‐amplifying process of Li dendrites (Figure g) . Similarly, Al 3+ ‐based colloidal particles and N ‐methyl‐ N ‐butylpiperidinium are also induced to stabilize Li metal anode based on electrostatic shield mechanism. In addition, Lewis acid AlI 3 are reported to suppress Li dendrites by facilitates the formation of Li–Al alloy and thin polymer films, respectively …”

on Li metal anode paired with sulfur/ oxygen cathode is highly concerned. [6] Li metal has extremely high theoretical specific capacity (3860 mA h g −1 ), nearly ten times higher than that of graphite anode, and the lowest reduction potential (−3.040 V vs. standard hydrogen electrode), which has been considered as a 'Holy Grail' anode in rechargeable batteries. [7] Moreover, Li metal anode can be paired with different cathode materials, such as intercalated cathodes (e.g., LiFePO 4 , [8] LiNi x Co y Mn 1−x−y O 2 [9,10] ) and conversion cathodes (e.g., S, [11,12] O 2 [13] ), to construct different types of high energy density batteries. The specific energy densities of Li metal batteries are very hopeful to approach 500 Wh kg −1 in the next 5 to 10 years according to the goal of US Department of Energy.Nevertheless, the rechargeable Li metal batteries have not been large-scale released yet. Li metal anode was first applied in Li-TiS 2 rechargeable batteries. In 1980s, the first-generation rechargeable Li metal batteries were commercialized by MOLI energy. [14] However, there were incessant reports about the fires and explosion events of rechargeable Li metal batteries. Safety issue has been the grand challenge hindering the practical applications of Li metal batteries since then. The main origin of safety issue comes from Li dendrites, i.e., random and spiculate Li deposition, which is induced by unstable interfaces between Li metal and liquid electrolyte. [2,15] Due to its extreme reactivity, Li metal can react with nearly all electrolytes, inducing the spontaneous decomposition of organic electrolyte. [16] The reaction products between Li and electrolyte constitute the solid electrolyte interphase (SEI) on Li metal anode, which was first named by Peled in 1979. [17] However, the formed SEI is fragile and heterogeneous with varied spatial resistance, [18,19] which induces uneven Li ions flux and random Li deposition underneath. Consequently, the surface of Li metal in a working cell is not uniform, where there are many protuberances enhancing the local electric field and attracting Li ions to deposit. [20] When the Li ion concentration near anode surface decreases to zero at the characteristic time (named as Sand's time), [21] scarce Li ions aggravate the nonuniformity of Li deposition and accelerate the growth of Li dendrites, which is a self-amplifying process. [22] The dendritic Li can easily pierce fragile SEI and induce the rapid decomposition of liquid electrolyte to form new SEI. [19,23] In the subsequent stripping process, gracile Li dendrites may break from the roots forming dead Li. [24] The repeated formation of SEI and dead Li give rise to low Coulombic efficiency. [15] Additionally, interfacial resistance Lithium metal has been considered as one of the most promising anode materials in high-energy-density rechargeable batteries due to its extremely high specific capacity and very low reduction potential of all possible candidates. However, the mysterious interfacial phenomena of lithium metal ano...

“…A common approach for the formation of artificial SEI on the metal involves use of special electrolyte additives such as vinylene carbonate 31, 32 , fluoroethylene carbonate 33 , dioxane 34 , sultones 30, 35 , or functional ionic liquids 7, which can electro-polymerize on the surface of electrode to form an elastic coating that protects the metal surface and accommodate volume changes in the electrode during charge and discharge. There are also recent reports of protecting the electrode interface by direct formation of a barrier layer by deliberate reaction between electrodes and reactive species in electrolytes 36–38 . Various indirect methods have also been reported for stabilizing a Li anode during battery recharge.…”

Designing solid-liquid interphases for sodium batteries

Secondary batteries based on earth-abundant sodium metal anodes are desirable for both stationary and portable electrical energy storage. Room-temperature sodium metal batteries are impractical today because morphological instability during recharge drives rough, dendritic electrodeposition. Chemical instability of liquid electrolytes also leads to premature cell failure as a result of parasitic reactions with the anode. Here we use joint density-functional theoretical analysis to show that the surface diffusion barrier for sodium ion transport is a sensitive function of the chemistry of solid–electrolyte interphase. In particular, we find that a sodium bromide interphase presents an exceptionally low energy barrier to ion transport, comparable to that of metallic magnesium. We evaluate this prediction by means of electrochemical measurements and direct visualization studies. These experiments reveal an approximately three-fold reduction in activation energy for ion transport at a sodium bromide interphase. Direct visualization of sodium electrodeposition confirms large improvements in stability of sodium deposition at sodium bromide-rich interphases.
