Achieving Stable Cycling of LiCoO2 at 4.6 V by Multilayer Surface Modification

Cheng Tao et al.

Summary: LiCoO2, first proposed as a cathode material by Prof. John B. Goodenough in 1980, remains one of the most popular commercial cathodes for lithium-ion batteries. Efforts have been made to increase its capacity by charging to high voltage, but issues such as structural instability and side reactions with electrolytes can occur. A surface modification strategy with a multilayer structure involving Zn-rich coating, rock-salt buffer layer, and Al doping layer has been proposed to enhance stability and achieve stable cycling of LiCoO2 at 4.6 V, with a capacity retention of 65.7% after 500 cycles.

A Growing Appreciation for the Role of LiF in the Solid Electrolyte Interphase

Jian Tan et al.

Summary: Rechargeable lithium batteries have transformed energy storage technology, but their further commercialization is hindered by short lifetime and safety issues, mainly due to the unstable solid-electrolyte interphase (SEI) and uncontrolled lithium dendrite growth. Research on SEI worldwide has focused on its debated structure and composition, particularly the role of the main component LiF. This review covers the development history of the SEI model, fundamental understanding of SEI, categorization of anode materials generating LiF in SEI, characterization techniques of SEI layers, transport mechanism of Li+ ions within SEI, physical properties of LiF, and analysis of LiF sources, offering insights for future research directions to promote large-scale applications of lithium metal batteries.

Enhanced Cycle Life and Rate Capability of Single-Crystal, Ni-Rich LiNi0.9Co0.05Mn0.05O2 Enabled by 1,2,4-1H-Triazole Additive

Yue Zou et al.

Summary: A novel electrolyte additive, 1,2,4-1H-triazole (HTZ), was introduced to enhance the interfacial stability and cycle life of LiNi0.9Co0.05Mn0.05O2 (NCM90). HTZ inhibits thermal decomposition of LiPF6 salt and suppresses HF acidic species, leading to the formation of a compact and dense CEI layer. The NCM90 cells with 0.3% HTZ-added electrolyte retain 86.6% of their original capacity after 150 cycles at 30 degrees C.

Lithium-Aluminum-Phosphate coating enables stable 4.6 V cycling performance of LiCoO2 at room temperature and beyond

Xiao Wang et al.

Summary: By using a surface engineering strategy with lithium-aluminum-phosphate composite coating materials, stable cycling of LCO at 4.6 V (vs. Li/Li+) was achieved, preventing direct contact between the cathode and electrolyte, reducing active material loss without hindering lithium ion migration. The doping layer formed after calcination includes phosphorus and aluminum, helping maintain surface structure and stabilize oxygen atoms around the particle surface, showing high ion mobility when operated at 4.6 V (vs. Li/Li+).

High-voltage liquid electrolytes for Li batteries: progress and perspectives

Xiulin Fan et al.

Summary: The energy density of LIBs has been increased threefold since their introduction, but the capacity of transition metal oxide cathodes is approaching its limit due to stability limitations of electrolytes. To further enhance energy density, new high-capacity and high-voltage cathode materials need to be explored, and graphite anodes may need to be replaced. One of the main challenges for future development is the development of new electrolyte compositions that can accommodate high-voltage cathodes and anodes while ensuring the stability of the batteries.
