Impact of the Local Environment on Li Ion Transport in Inorganic Components of Solid Electrolyte Interphases

Taiping Hu et al.

Summary: The Li ion transport mechanism in amorphous LiF and Li2CO3, the major inorganic components of the solid electrolyte interphase (SEI), is investigated through machine-learning-potential-assisted molecular dynamics simulations. Results show that the Li ion diffusivity in amorphous LiF at room temperature cannot be accurately predicted based on high temperature diffusivities. The formation of Li-F regular tetrahedrons at low temperatures greatly suppresses the Li ion diffusivity, suggesting that designing an amorphous bulk LiF-based SEI is not beneficial for Li ion transport.

Highly soluble organic nitrate additives for practical lithium metal batteries

Zhe Wang et al.

Summary: The stability of lithium metal anodes crucially determines the lifespan of high-energy-density lithium metal batteries. Traditional additive lithium nitrate (LiNO3) forms LiNxOy-containing solid electrolyte interphase (SEI) to stabilize lithium metal anodes, but its poor solubility in ester electrolytes hinders its application. In this study, organic nitrate isosorbide nitrate (ISDN) is proposed as a replacement for LiNO3. ISDN exhibits high solubility in ester electrolytes due to the introduction of organic segments, enabling the formation of LiNxOy-rich SEI and promoting uniform lithium deposition. The lifespan of lithium metal batteries is significantly extended from 80 to 155 cycles with the use of ISDN under demanding conditions. Furthermore, a lithium metal pouch cell with an energy density of 439 Wh kg(-1) delivers 50 cycles. This work opens up a new pathway for developing practical additives for lithium metal batteries through molecular modifications.

Lijiang Tan et al.

Summary: A rationally designed ether-based electrolyte with chlorine functionality is reported to address the issues of low anodic stability and high flammability in high-voltage lithium metal batteries. The chloroether-based electrolyte shows high Li Coulombic efficiency and capacity retention, and possesses nonflammable safety feature due to the flame-retarding ability of chlorine functional groups. This study offers a new approach for enabling ether-based electrolytes in high energy density, long-life, and safe Li metal batteries.

A lightweight localized high-concentration ether electrolyte for high-voltage Li-Ion and Li-metal batteries

Xudong Peng et al.

Summary: The emerging localized high-concentration electrolytes (LHCEs) with small salt dosage, low viscosity, and favorable electrode wettability have triggered extensive research interest recently. In this study, an anode-compatible and high-voltage ether-based LHCE (BTF-LHCE) is proposed by introducing cost-efficient and lightweight benzotrifluoride (BTF) as a diluent. The BTF-LHCE system exhibits unique solvation structure and interfacial chemistry, leading to high Coulombic efficiency (CE) for both Si and metallic Li anodes. The Si||NCM622 and Li||NCM622 pouch cell assembled with BTF-LHCE show high cell-level specific energy densities, indicating the promising potential of the advanced ether-based electrolytes for high-voltage and high-specific-energy battery technologies.
