B/Al Codoped/Coated Ultra-High Nickel Cobalt-Free Material with Excellent High Voltage/Rate Cycle Stability

ACS Sustainable Chemistry & Engineering, Journal Year: 2024, Volume and Issue: 12(24), P. 9168 - 9179

Published: June 5, 2024

Ultrahigh nickel cobalt-free cathode materials have high energy density and are very promising for application in lithium-ion batteries. However, they face severe challenges of overall degradation the interface/lattice structure stability during charge discharge, resulting poor safety a short cycle life. In this paper, B/Al codoping/coating is applied to LiNi0.9Mn0.1O2 (NM90). The LiAlO2/LiBO2 coating formed situ by surface residual alkali helps reduce O2 evolution restrain side reactions on surface. codoping from high-temperature thermal diffusion significantly expands layer spacing, thus improving Li+ rate. After 300 cycles, optimized NM90-1% AB material achieves 86.5% capacity retention (1 C, 2.7–4.3 V, 25 °C) compared 68.5% pristine NM90 material. Furthermore, its can reach 84.7% after cycles at 4.4 V 5 which much higher than 58.9% Even 10 specific discharge still 155.1 mA h/g, but only has 142.8 h/g.

All-Dry Solid-Phase Synthesis of Single-Crystalline Ni-Rich Co-Poor Ternary Cathodes for Li-Ion Batteries

Industrial & Engineering Chemistry Research, Journal Year: 2024, Volume and Issue: 63(26), P. 11710 - 11716

Published: June 20, 2024

All-dry solid-phase synthesis (ADSPS) is considered an eco-friendly and cost-effective method for preparing Ni-rich Co-poor cathodes, yet slow ion diffusion during the sintering process results in agglomerate particles with severe Li/Ni mixing. Herein, a Mg/Sr-codoped ZrO2-coated single-crystalline LiNi0.73Co0.05Mn0.22O2 cathode well-layered structure fabricated through ADSPS method. The Sr ions effectively accelerate migration at grain boundary to facilitate particle coarsening, while Mg act as "pillar ions" decrease mixing improve structural stability. Moreover, ZrO2 coating layer can further alleviate interfacial side reactions hinder degradation enhance integrity. Therefore, resultant cathodes deliver high reversible capacity of 192.4 mAh g–1 display impressive retention 87.5% after 300 cycles 0.5 C pouch-type full cell. strategy this work shows great potential ternary Li-ion batteries.

Creating Single‐Crystalline β‐CaSiO₃ for High‐Performance Dielectric Packaging Substrate

Advanced Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Dec. 23, 2024

Abstract β‐CaSiO 3 based glass‐ceramics are among the most reliable materials for electronic packaging. However, developing a CaSiO glass‐ceramic substrate with both high strength (>230 MPa) and low dielectric constant (<5) remains challenging due to its polycrystalline nature. The present work has succeeded in synthesizing single‐crystalline high‐performance substrate. This is accomplished by introducing Al 3+ into CaO‐B 2 O ‐SiO glass system, optimizing sintering condition. doping facilitates heterogeneous network structure that energetically favors precipitation of particles, including nanosized crystals sub‐nanosized α‐CaSiO crystals. As temperature increases, nano (2–10 nm) gradually absorbed Through atomic rearrangement, transform micrometer‐sized single crystal (1–2 µm) layered structure. co‐fired exhibit exceptional properties, 4.04, loss 3.15 × 10 −3 at 15 GHz, flexural 256 MPa. provides new strategy fabricating packaging other applications.
