“…Results on Li 3 PS 4 and Ag 3 PS 4 served as reference for interpreting the data. [ 35 ] The spectra were in good agreement, which is reasonable considering that γ−Li 3 PS 4 , Ag 3 PS 4 and Cu 3 PS 4 share the same crystal structure and space group ( Pmn 21). Doublet peaks (energy separation = 1.2 eV) at binding energies (BE) of 162.0 eV for the S2p signal can be related to the transition metal‐PS 4 3− bondings by comparison with literature data on Li 3 PS 4 and Ag 3 PS 4 .…”

“…[ 23c ] Qiao et al explain that amorphization leads to a shift of the P–S–P binding energies to lower values. [ 35b ] Consequently, the overall broad peak related to the S2p signal may be also due to an overlay of crystalline and amorphous Cu 3 PS 4 . Note that there was no indication for other phases by XRD (Figure 1).…”

Lithium and sodium thiophosphates (and related compounds) have recently attracted attention because of their potential use as solid electrolytes in solidstate batteries. These compounds, however, exhibit only limited stability in practice as they react with the electrodes. The decomposition products partially remain redox active hence leading to excess capacity. The redox activity of thiophosphates is explicitly used to act as electrode for sodium-ion batteries. Copper thiophosphate (Cu 3 PS 4 ) is used as a model system. The storage behavior between 0.01 and 2.5 V versus Na + /Na is studied in half cells using different electrolytes with 1 m NaPF 6 in diglyme showing the best result. Cu 3 PS 4 shows highly reversible charge storage with capacities of about 580 mAh g −1 for more than 200 cycles @120 mA g −1 and about 450 mAh g −1 for 1400 cycles @1 A g −1 . The redox behavior is studied by operando X-ray diffraction and X-ray photoelectron spectroscopy. During initial sodiation, Cu 3 PS 4 undergoes a conversion reaction including the formation of Cu and Na 2 S. During cycling, the redox activity seems dominated by sulfur. Interestingly, the capacity of Cu 3 PS 4 for lithium storage is smaller, leading to about 170 mAh g −1 after 200 cycles. The results demonstrate that thiophosphates can lead to reversible charge storage over several hundred cycles without any notable capacity decay.

The continuous depletion of fossil fuels, the increase of oil prices, and the need to decrease CO 2 emissions have stimulated intensive research on developing alternative renewable and clean energy sources. [1] Among these alternative energy sources, rechargeable Li-ion batteries (LIBs) are one of the promising candidates. To date, the LIBs basically consisting of a positive electrode (cathode), an electrolyte, and a negative electrode (anode) have widespread applications, such as portable electronic devices, pure electric vehicles (PEVs), and hybrid electric vehicles (HEVs). [2] The state-of-the-art electrolytes are usually the lithium salts (LiPF 6 , LiBF 4 , and LiCF 3 SO 3 ) dissolved in organic solvents, i.e., ethylene carbonate, propylene carbonate, polyethylene oxide, and dimethyl carbonate, [3] which exhibit excellent wetting of the electrodes and produce a fast transfer of Li + ions upon charging and discharging. However, they suffer from flammability, poor electrochemical stability, limited temperature range of operation, and low power density. [4] There is an ever-increasing demand for batteries with a higher energy and power density, although current LIBs offer volumetric and gravimetric energy densities up to 770 Wh L −1 and 260 Wh kg −1 , respectively. [5] To improve the energy/power density of LIBs, one way is to adopt high-potential cathode materials such as LiNi 0.5 Mn 1.5 O 4 (LNMO). The high-voltage plateau of LNMO (≈4.7 V vs Li/Li + ) makes its energy density 20-30% higher than the energy density of commercial LiCoO 2 and LiFePO 4 . [6] However, successful commercialization of the LNMO is restricted in high-energy LIBs due to electrolyte decomposition and side reaction of the cathodes and liquid electrolytes when operating at high voltages. [7,8] The other way to improve the energy/power density is to replace the conventional graphite anode with Li metal. The Li metal, with a low anode potential (−3.04 V vs standard hydrogen electrode) and high specific capacity (3862 mAh g −1 for the Li anode versus 372 mAh g −1 for the graphite anode), [9][10][11] has been considered as the "Holy Grail" of battery technologies. When paired with sulfur and oxygen, the theoretical energy density of Li-S (≈2567 Wh kg −1 ) and Li-O 2 (≈3505 Wh kg −1 ) batteries is far higher than the theoretical energy density of conventional LIBs (≈387 Wh kg −1 ). [12][13][14][15] When Li metal approaches the liquid electrolytes, however, unstable Li/electrolyte interface Rechargeable Li-ion batteries (LIBs) are electrochemical storage device widely applied in electric vehicles, mobile electronic devices, etc. However, traditional LIBs containing liquid electrolytes suffer from flammability, poor electrochemical stability, and limited operational temperature range. Replacement of the liquid electrolytes with inorganic solid-state electrolytes (SSEs) would solve this problem. However, several critical issues, such as poor interfacial compatibility, low ionic conductivity at ambient temperatures, etc., need to be surmounted befor...

Solid‐state lithium (Li) metal batteries (SSLMBs) have become a research hotspot in the energy storage field due to the much‐enhanced safety and high energy density. However, the SSLMBs suffer from failures including dendrite‐induced short circuits and contact‐loss‐induced high impedance, which are highly related to the Li plating/stripping kinetics and hinder the practical application of SSLMBs. The maximum endurable current density of lithium battery cycling without cell failure in SSLMB is generally defined as critical current density (CCD). Therefore, CCD is an important parameter for the application of SSLMBs, which can help to determine the rate‐determining steps of Li kinetics in solid‐state batteries. Herein, the theoretical and practical meanings for CCD from the fundamental thermodynamic and kinetic principles, failure mechanisms, CCD identifications, and influence factors for improving CCD performances are systematically reviewed. Based on these fundamental understandings, a series of strategies and outlooks for future researches on SSLMB are presented, endeavoring on increasing CCD for practical SSLMBs.
