“…32 No dendrite formation was observed in a Li/PEO 20 LiTFSI/Li cell at a low current density of 0.05 mA cm ¹2 for 100 h at 80°C, while at a high current density of 0.7 mA cm ¹2 , dendrites were observed in less than 1 h deposition. 28 Similar results 29 were reported for the same type cell, where dendrite growth started at 2 h deposition with a polarization of 0.4 mA cm…”

This article summarizes our research on aqueous lithium-air rechargeable batteries. Lithium-air batteries have a far higher energy density and lower material cost than lithium-ion batteries, so that they are now attracting growing attention as possible power sources for electric vehicles. Presently, two types of rechargeable lithium-air batteries have been developed; non-aqueous and aqueous types. The aqueous type has a lower specific energy density than the non-aqueous system, but overcomes some severe problems that must still be addressed for the non-aqueous type, such as lithium metal corrosion by water from air and the high polarization of electrode reactions. The key component of the aqueous lithium-air battery is a water-stable lithium metal electrode (WSLE). The WSLE developed in our laboratory consists of lithium metal covered with a lithium conducting polymer electrolyte and a lithium conducting water-stable solid electrolyte, which was successfully operated in a saturated LiOH and LiCl aqueous solution.

“…The dendrite formation onset time is dependent on the polarization density. Brissot et al 28,29 reported that the dendrite growth in Li/PEO 20 LiTFSI/Li corresponded to the model proposed by Chazalviel 38 in the current density range of 0.020.3 mA cm…”

“…The authors emphasized that good contact between the polymer and lithium is also of great importance for the suppression of dendrites. Direct in-situ observation of lithium dendritic growth in Li-imide P(EO) 20 polymer electrolyte 60 shows that dendrites grow at a rate close to that of anionic drift.…”

The Solid-Electrolyte-Interphase (SEI) model for non-aqueous alkali-metal batteries constitutes a paradigm change in the understanding of lithium batteries and has thus enabled the development of safer, durable, higher-power and lower-cost lithium batteries for portable and EV applications. Prior to the publication of the SEI model (1979), researchers used the Butler-Volmer equation, in which a direct electron transfer from the electrode to lithium cations in the solution is assumed. The SEI model proved that this is a mistaken concept and that, in practice, the transfer of electrons from the electrode to the solution in a lithium battery, must be prevented, since it will result in fast self-discharge of the active materials and poor battery performance. This model provides [E. Peled, in "Lithium Batteries," J.P. Gabano (ed), Academic Press, (1983), E. Peled, J. Electrochem. Soc., 126, 2047Soc., 126, (1979.] new equations for: electrode kinetics (i o and b), anode corrosion, SEI resistivity and growth rate and irreversible capacity loss of lithium-ion batteries. This model became a cornerstone in the science and technology of lithium batteries. This paper reviews the past, present and the future of SEI batteries. The PastPrior to the publication of the SEI model (1979), 1,4 researchers used the Butler-Volmer equation, in which direct electron transfer from the electrode to lithium cations in the solution is assumed. It was generally assumed that the rate-determining step (RDS) is the transfer of electrons from the metal to the cations in the solution. Researchers found that the lithium anode is covered by a passivating layer which interferes with the deposition/dissolution process of the anode. Brummer and Newman 2,3 concluded that a passivating anode can offer only a limited cycle life and in order to obtain a deep-discharge high-cycle-life secondary battery, the lithium anode must be free of a passivating layer and kinetically stable with respect to the electrolyte. The SEI model proved that this is a mistaken concept and that, in practice, the transfer of electrons from the electrode to the solution in a lithium battery, except when forming a SEI, must be prevented. The Present, Lithium-Metal and Lithium-Ion BatteriesIntroduction.-It is now generally accepted that the solidelectrolyte interphase (SEI) is essentially for the existence and successful operation of lithium-and sodium-battery systems, as primary and secondary power sources. 4 In 1979, it was proposed by Peled,

“…The growth of ramified metallic electrodeposition in dilute salt solutions is essentially driven by the space charge that tends to develop upon anion depletion near the cathode. Rosso and co-workers 8,9,29,30 and Liu et al 31 have extensively studied lithium dendrite formation for the Li/PEO-LiTFSI/Li cell using a direct in situ observation technique. The experimental results have been compared with the theoretical model proposed by Chazalviel.…”

Lithium Dendrite Formation on a Lithium Metal Anode from Liquid, Polymer and Solid Electrolytes

Lithium metal is the most attractive anode material for batteries because of its high specific capacity (3861 mAh g −1 ) and low negative potential (−3.04 V vs. NHE). However, lithium dendrite growth during lithium deposition leads to serious safety problems and poor cycling performance. The conventional liquid electrolyte used in lithium-ion batteries results in significant lithium dendrite formation at room temperature and a high current density. Thus, there has been much research effort to achieve the suppression of lithium dendrite formation. Recently, a new class of non-aqueous liquid electrolyte with a high concentration of lithium salts, such as solvated ionic liquid and solvent-in-salt electrolytes, has been reported to suppress lithium dendrite formation. Solid polymer electrolytes have been known to suppress lithium dendrite formation; however, the low lithium ion conductivity and high interface resistance between lithium and the polymer electrolyte at room temperature limits their use for conventional batteries. The interface resistance was significantly decreased by the addition of an ionic liquid into a polymer electrolyte and lithium dendrite formation was suppressed. A theoretical analysis predicted that if a homogenous solid electrolyte with a shear modulus of 6 GPa was obtained, then the lithium dendrite problem would be solved. However, some lithium conducting solid electrolytes such as Li 7 La 3 Zr 2 O 12 still exhibit lithium dendrite formation. In this review, we introduce the recent status of lithium dendrite formation on lithium metal in contact with liquid, solid polymer, and solid electrolytes.
