High Quality NaxTMO2 Anode Material for Sodium Ion Batteries

The anode material of sodium ion batteries is a key component that determines the energy density, cycle life, cost, and safety of the battery.

Description of NaxTMO2 Anode Material

Layered oxide is currently one of the most promising and widely used systems in the industrialization of positive electrode materials for sodium ion batteries. Its structure is very similar to the ternary materials (NCM/NCA) of lithium-ion batteries, so it can be quickly reused in production processes and equipment, greatly promoting its commercialization process.

Features of NaxTMO2 Anode Material

Core structure and working principle
Chemical formula: NaxMO ₂

Na: Represents reversible insertion and extraction of sodium ions.

x: The sodium content usually varies between 0.4 and 1.0, depending on the specific material and charge discharge state.

M: Representing one or more transition metal elements, such as Mn (manganese), Fe (iron), Ni (nickel), Cu (copper), Co (cobalt), Ti (titanium), etc. By combining different elements, the properties of materials can be regulated.

Crystal structure: Its crystal can be seen as a “sandwich” structure – an octahedral layer (MO ₂ layer) composed of transition metal (M) and oxygen (O), alternately stacked with a layer of sodium ions (Na).

Key classification: According to the occupation position and stacking sequence of sodium ions, they are mainly divided into two types:

O3 type: Sodium ions are located in the octahedral position, with a stacking sequence of ABCABC. When the sodium content is high (x~1), this structure is usually present. Its operating voltage platform is relatively low, but its initial capacity is high.

P2 type: Sodium ions are located on triangular columns, with a stacking sequence of ABBA. Usually stable at low sodium content (x~0.7). Its sodium ion diffusion channel is more spacious, resulting in higher ion conductivity, better rate performance, and cycling stability than O3 type, which is currently the focus of research and application.

 Application of NaxTMO2 Anode Material

Layered oxide cathode materials are considered an ideal choice for sodium ion batteries in scenarios with high power and energy requirements, such as electric vehicles, two wheelers, and start stop power supplies, due to their high energy density and fast charging and discharging capabilities.

The current research focus is on:

Surface modification: Insulation against air and electrolyte erosion by coating (such as Al2O3).

Body phase doping: Introducing inert elements such as Mg, Al, Ti as “pillars” to stabilize the crystal structure.

Structural design: Prioritize the development and application of P2 type materials or O3/P2 composite phase materials with more stable structures.

Improved air stability: By optimizing composition design and synthesis processes, materials that are insensitive to air can be prepared, simplifying production, storage, and battery manufacturing processes.

Storage Condition of NaxTMO2 Anode Material

Sealed Containers:Store NaxTMO2 Anode Material in airtight bags or jars. This stops moisture from getting in and keeps the powder dry.

Dry Environment:Keep it in a dry place. Use desiccants inside containers if needed. High humidity can make the powder clump together.

Avoid High Temperatures:Store at room temperature (15–25°C). Extreme heat can change the powder’s properties or cause it to decompose.

Separate from Acids:Don’t mix with acids. They can react and form silica gel, ruining the powder.

Label Clearly:Mark containers with the name, purity, and date. This helps avoid mistakes when using it later.

Use Proper Handlin:gloves when touching the powder. Clean up spills right away
