摘要
负极材料NaNi1/3Fe1/3Mn1/3O2 (NFM111)被称为钠离子电池的o3型层状氧化物。它具有能量密度高、易于合成等优点。然而,残碱导致容量衰减和空气稳定性下降。其存储和应用受到限制。通过磷酸处理,降低了NFM111表面残碱含量。在0.1℃下,改性材料的初始放电容量为162 mA h g-1,在0.1℃下,材料暴露于空气后仍具有140.7 mA h g-1的放电容量。这种处理策略增加了材料在25°C和- 20°C下的比放电容量,提高了循环稳定性和空气稳定性。为钠离子电池正极材料的生产和应用提供了一种有效可靠的方法。
Excellent Performance of Sodium Ion Battery Cathode Materials Benefiting from the Inorganic Acid Regulating Strategy
The cathode material NaNi1/3Fe1/3Mn1/3O2 (NFM111) is known as an O3-type layered oxide for sodium ion batteries. It has the advantages of high energy density and easy synthesis. However, the residual alkali leads to capacity decay and air stability decline. And its storage and application are limited. The residual alkali content on the surface of NFM111 is reduced through phosphoric acid treatment. The initial discharge capacity of the modified material is 162 mA h g–1 at 0.1 C. Meanwhile, the material still has a capacity of 140.7 mA h g–1 at 0.1 C after exposure to air. This treatment strategy increases the specific discharge capacity of the material at 25 and −20 °C and improves the cycle stability and air stability. It provides an effective and reliable method for the production and application of sodium ion battery cathode materials.
