Summary: A freestanding membrane with a unique bean pod-like structure composed of nitrogen-doped carbon fibers and hollow carbon spheres encapsulated with SnCo nanoparticles was synthesized. The Sn acts as a host for Na+ storage, while the Co serves as an electrochemically inactive matrix that buffers volume variations and inhibits aggregation and particle growth of the Sn phase. The introduction of hollow carbon spheres provides sufficient void space to withstand volume expansion and improves anode conductivity. The freestanding membrane also increases the contact area between the active material and the electrolyte, providing more active sites during cycling. When used as an anode material for Na-ion batteries, the B-SnCo/NCF anode exhibits excellent rate capacity and specific capacity.

Summary: Alloy electrodes with high energy density are gaining interest in the field of Li-ion batteries, but they suffer from rapid pulverization and disconnection due to large volume changes. Ga-based liquid alloys, such as galinstan, have been studied as self-healing electrodes due to their ability to store Li and remain in a liquid state at room temperature. However, the lithiation mechanism and practical capacity of galinstan are still unknown. This study used electrochemical measurements, XRD, and SEM analyses to investigate the redox processes and structural properties of galinstan as an electrode material.

Summary: The key to producing high-energy Li-ion cells is to ensure the stability of the interfaces between Si-containing anodes and Ni-rich cathodes. A multi-functional electrolyte additive, 4-(allyloxy)phenyl fluorosulfate (APFS), is used to create a solid electrolyte interphase (SEI) and a stable cathode-electrolyte interface. The combination of vinylene carbonate (VC) and APFS allows for high capacity and capacity retention in full cells.

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.

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.
