Perfluoro Macrocyclic Ether as an Ambifunctional Additive for High-Performance SiO and Nickel 88%-Based High-Energy Li-ion Battery

Min-Geun Oh et al.

Summary: The study proposes a new fluorinated additive, icosafluoro-15-crown 5-ether, which effectively reduces the swelling issue of the silicon anode in lithium-ion batteries, improves stability, and significantly reduces manufacturing cost. The additive also stabilizes the nickel-rich oxide cathode in high-capacity cells. When used together with a decreased fraction of FEC, reversible cycling for 300 cycles at high voltage and high rate was achieved. Material characterization results reveal that the stabilization is derived from the passivation of both anode and cathode surfaces.

Rational Design of Fluorinated Electrolytes for Low Temperature Lithium-Ion Batteries

Dong-Joo Yoo et al.

Summary: This study demonstrates a rational design of new electrolytes by tailoring the chemical structure of ethyl acetate solvent, which significantly improves the low temperature performance. The optimal electrolyte, 2,2,2-trifluoroethyl acetate, shows significantly improved cycle life and C-rate at -20°C and -40°C. Furthermore, this electrolyte is nonflammable and tolerant for high voltage charging due to its fluorine content. This work provides guidance for designing next-generation electrolytes for subzero temperatures.

Interplay of Lithium Intercalation and Plating on a Single Graphite Particle

Tao Gao et al.

Summary: Improving safety, increasing charging rates, and extending the lifetime of lithium-ion batteries is a major challenge, with the key being to control lithium plating on graphite anodes. Experimental studies have shown that the onset of plating is strongly coupled with phase separation in graphite, occurring only on the fully lithiated edges of particles. The competition between Li insertion and plating is further elucidated through energetics and kinetics analysis.

Solid Electrolyte Interphase Stabilization Path to Lithium Metal Plating-Free High-Energy Lithium-Ion Battery Under Subzero-Temperature

Yen Hai Thi Tran et al.

Summary: For the first time, a lithium metal plating-free and unprecedented high-performance graphite parallel to LiNi0.8Co0.1Mn0.1O2 (NCM811) full-cell under subzero-temperature of -10 degrees C and high-voltage of 4.45 V has been reported through the construction of robust solid electrolyte interphase (SEI) layers at both anode and cathode. The performance failure of commercial electrolyte-based full-cell under subzero-temperature operation is attributed to lithium metal plating at graphite anode and irreversible phase transformation of NCM811 to disordered H3 phase with a large volume contraction. The study clearly demonstrates the importance of anode-electrolyte and cathode-electrolyte interfacial stabilization, bulk structural stabilization of both anode and cathode, and highly reversible cycling performance under subzero-temperature.

Interfacial Model Deciphering High-Voltage Electrolytes for High Energy Density, High Safety, and Fast-Charging Lithium-Ion Batteries

Yeguo Zou et al.

Summary: High-voltage lithium-ion batteries using high-voltage electrolytes can improve energy density and power density, but face challenges such as electrolyte decomposition and unclear interfacial side reactions. A new additive-free electrolyte has been developed to address these issues, providing stability at high voltage, lithium-dendrite-free features during fast charging, and superior performance at low temperatures. Additionally, a new solvation structure-related interfacial model has been introduced to help interpret battery performance and guide the design of versatile electrolytes for metal-ion batteries.
