Summary: This study presents an in situ prelithiation method by integrating a Li metal mesh into the cell assembly to spontaneously prelithiate Si with electrolyte addition. The prelithiation amount can be precisely controlled by using Li meshes with different porosities, and the uniformity of prelithiation is enhanced by the patterned mesh design. With optimized prelithiation amount, the in situ prelithiated Si-based full cell exhibits a constant >30% capacity improvement in 150 cycles.

Summary: A multifunctional amide-multiwalled carbon nanotube (A-MWCNT) interlayer is designed to address the challenges of lithium-sulfur (Li-S) batteries. The amide-rich interlayers promote the formation of conductive solid electrolyte interphase (SEI) layers, and reduce the thickness of the SEI layer, improving electrolyte retention capability. This interlayer significantly suppresses the shuttle effect and enables Li-S batteries with high initial capacity, low decay rate, and high current rate.

Summary: The study introduces 1,2-diethoxyethane (DEE) as a new electrolytic solvent for lithium metal batteries (LMBs), which shows improved cycling stability and Coulombic efficiencies. The use of DEE helps in reducing dendrite growth, preventing unwanted side-reactions, and creating possibilities for high-energy-density rechargeable LMBs.

Summary: The problems of zinc anode, such as dendrite growth and hydrogen evolution, significantly impair the performance of zinc batteries. The solid electrolyte interphase (SEI), crucial for achieving high reversibility of lithium anode in non-aqueous organic solvents, also contributes to the improvement of zinc anode performance in aqueous electrolytes. However, current research on the interphase for zinc electrodes is fragmented, lacking a deep understanding of the underlying causes or general design rules for SEI construction. The high reactivity of water molecules poses a serious challenge for effective SEI formation.

Summary: Trace water has a fatal impact on the performance of lithium-ion batteries, as shown in this study where additional H2O alters solvent structures and leads to excessive SEI film growth. These findings highlight the detrimental effects of water impurities on the conductive properties of SEI films and the electrochemical performance of LIBs.

Summary: Mono-solvent DMC electrolyte is used for the first time in contact prelithiation, and the low-organic-content REI formed by this electrolyte is found to be a mixed ion/electron conductor. As a result, electron channels can be maintained even when the Li source is completely wrapped by the DMC-derived REI, leading to outstanding Li source utilization and negligible dead Li yield.

Summary: Silicon is promising for lithium storage due to its high capacity and low working platform, but volume changes during cycling lead to material pulverization and electrode cracking. A robust binder is essential for maintaining Si electrode integrity, yet its role in modulating the chemical composition and spatial distribution of the SEI layer is often overlooked.

Summary: A stable solid electrolyte interphase (SEI) layer is crucial for high performance lithium ion and lithium metal batteries. Understanding the mechanical properties and behavior of the SEI is essential for rational design, but challenging due to its thin and air-sensitive nature. Various techniques have been used to study the mechanics of SEI, but there is a lack of concise review on the findings so far.

Summary: This study demonstrates the role of a lithium oxysulfide-rich solid electrolyte interphase (SEI) in shielding parasitic reactions and improving the lifespan of lithium-sulfur batteries. The SEI layer, which introduces abundant lithium oxysulfide components, effectively shields the parasitic reactions and increases the lifespan of the batteries by 60% under demanding conditions.

Summary: The formation of unstable SEI layers in non-aqueous electrolytes is a major issue for the long-life cycling of rechargeable batteries, especially at high temperatures. Including a small dose of VC additive in the batteries' electrolyte can help overcome this problem. VC has shown great potential in building protective layers with good integrity and thermal stability at anodes. This review summarizes recent advances in the application of VC in electrolytes of rechargeable batteries.

Summary: This study investigated the effect of different carbon host materials, acetylene black (AB) and active carbon (AC), on the performance of lithium-sulfur (Li-S) batteries. The results showed that despite active carbon having a larger surface area, the sulfur composite cathode with acetylene black exhibited better cycling and kinetic performance, indicating that the electrical conductivity of the carbon host material plays a dominant role in affecting the battery performance.
