Sodium Manganese Oxide

Basic Parameters

Properties

• Good cycle stability. Sodium manganese oxide generally exhibits good cycle stability, and its performance degradation is relatively small even after long-term use, ensuring the long-term performance of the battery.
• High theoretical specific capacity. Sodium manganese oxide has a high theoretical specific capacity, which means that it can store more energy at the same weight or volume, thereby improving the energy density of the battery.

Preparation

Sodium manganese oxides can be prepared using a variety of methods:

• Solid-state reaction. Solid-state reaction is a common method where sodium-containing compounds (like Na₂CO₃) and manganese oxides (like Mn₂O₃) are mixed and heated at high temperatures to induce the desired phase formation.
• Sol-gel method. Sol-gel method involves transitioning metal alkoxides through a sol-gel process, resulting in better precursor mixing and control over particle size and morphology.
• Hydrothermal and solvothermal methods. Hydrothermal and solvothermal methods utilize aqueous or organic solvents at elevated temperatures and pressures to crystallize the material, often leading to well-ordered and high-purity products.
