AI Article Synopsis
- ZnCoO is a popular anode material for lithium-ion batteries due to its high capacity, low cost, and environmental friendliness, but it suffers from poor conductivity and cycle stability.
- To address these limitations, a novel 3D nanoflower composite (ZnCoO@CN-B) was developed by combining ZnCoO with B-doped g-CN through a hydrothermal method.
- This composite demonstrated impressive performance, including a specific capacity of 919.76 mA h g after 500 cycles and 97.8% capacity retention after 1000 cycles, showcasing its potential for practical applications in battery technology.
Article Abstract
ZnCoO has become one of the most widely used anode materials due to its good specific capacity, cost-efficiency, high thermal stability and environmental benignity. However, its poor conductivity and cycle stability have limited its practical application in lithium-ion batteries. To overcome these issues, we constructed a 3D nanoflower composite material (ZnCoO@CN-B) by combining ZnCoO as a framework and B-doped g-CN (g-CN-B) as a new carbon source material a simple hydrothermal method. ZnCoO@CN-B exhibited exceptional specific capacitance of 919.76 mA h g after 500 cycles at 0.2 A g and a long-term capacity retention of 97.8% after 1000 cycles at 2 A g. The high reversible capacity, long cycling life and good rate performance could be attributed to the 3D interconnected architecture and doping of g-CN-B. This work provides a simple and general strategy to design high-performance anode materials for lithium-ion batteries to meet the needs of practical applications.

Modulating the surface microenvironment of electrodes stands as a pivotal aspect in enhancing the electrocatalytic performance for CO2 electroreduction. Herein, we propose an innovative approach by incorporating a small amount of linear oligomer, polyethylene glycol (PEG), into Cu2O catalysts during the preparation of the CuPEG electrode. The Faradaic efficiency (FE) toward multicarbon products (C2+) increases from 69.

Calcium metal batteries with high capacity and low cost are promising alternatives to Li-ion batteries for large-scale energy storage. However, its development is crucially impeded by the irreversible Ca metal anode, which is highly associated with uncontrollable Ca plating/stripping. Here, we report a new riveting strategy to regulate the nucleation and growth of a Ca metal anode in the 3D structure of a carbon nanotube film (CNF) by introducing in situ-formed Na metal mediators.

All-solid-state chloride-ion batteries promise high theoretical energy density and room-temperature operation. However, conventional Sn anodes suffer from low material utilization attributed to large particle size and volume expansion. Here, nano-sized Sn particles in an N-doped carbon framework are used as an anode, resulting in ∼12% higher capacity compared to conventional Sn, due to improved Sn utilization and suppression of volume expansion.

Room-temperature sodium-sulfur (RT Na-S) batteries that typically feature multielectron conversion chemistries can allow an ultrahigh specific capacity of 1675 mA h g and a high energy density of 1275 W h kg but unfortunately suffer from a lot of intractable challenges from sulfur cathodes. These issues cover the poor electronic conductivity of pristine sulfur and solid products, the severe shuttle effect of polysulfides, and the sluggish redox kinetics, The shuttling behavior of polysulfides always leads to cathode/anode instability and performance degeneration. Recently, the emerging catalysis strategy has been demonstrated as a reliable pathway to tackle the central issues caused by sulfur electrochemistry and revitalize RT Na-S batteries.

Background: Adolescent idiopathic scoliosis (AIS) is characterized by an asymmetrical formation of the spine and ribcage. Recent work provides evidence of asymmetrical (right versus left side) paraspinal muscle size, composition, and activation amplitude in adolescents with AIS. Each of these factors influences muscle force generation.
