“…Figure 2 shows the variation of the lithium dendrite formation onset time R cc , as a function of the current density J, at 90°C. 30 The time R cc follows a power law with respect to J, very close to Sand's theory in the current density range of 0.02 to 0.3 mA cm…”

“…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

2016

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.

“…The curve shows good linearity in the range of 0.10.5 mA cm ¹2 with a slope of ¹1.25. In this current range, the dendrite growth could not be explained by the Chazalviel model, which indicates that local fluctuation of the current density may be an important factor, as indicated by Rosso et al 30 The addition of nanosize SiO 2 into Electrochemistry, 80(10), 706715 (2012) PEO 18 LiTFSI and PEO 18 LiTFSI-1.44PP13TFSI was effective to suppress dendrite formation. 40 According to Eq.…”

Aqueous Lithium-Air Rechargeable Batteries

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.

“…Since the dendrites are partially inactive during the following discharge cycle, this reduces the efficiency of the cell during Li dissolution/deposition cycles. 18,19 To verify the growth of Li dendrites, the microstructure of the Li metal anode surface was examined after various discharge cycles. Although dendrites form during the charge reaction, we obtained SEM images after each discharge reaction to confirm that dendrites had formed and were reducing the cell capacity.…”

Li Utilization and Cyclability of Li-O2 Rechargeable Batteries Incorporating a Mesoporous Pd/^|^beta;-MnO2 Air Electrode

2014

The effects of Li utilization on the capacity and cycle stability of Li-O 2 batteries were studied by investigating the performance of cells incorporating varying ratio of Li metal to air electrode catalyst. The quantity of Li metal was found to affect the overall discharge capacity, such that the capacity decreased with decreasing amounts of Li in the anode. Although a capacity of only 354 mAh g −1 (cathode) was obtained when the anode contained 0.9 mg Li, almost 100% of the Li in the cell was consumed during discharge, which corresponds to a capacity of 3932 mAh g −1 (Li). The cycle stability of cells operating under high Li utilization conditions was, however, significantly reduced. Detailed analysis of the Li distribution in the cell suggests that decreased usage of Li within the first few cycles is the cause of the poor cycle stability. The results of this study suggest that low cycle stability in a Li-O 2 battery may be attributed to the formation of a surface passivation layer on the Li metal composed primarily of Li 2 CO 3 and ROCO 2 Li and generated by reaction with the electrolyte.
