Segmentation by Product Type

The high purity boehmite market for Li-ion batteries is primarily divided into two key product categories based on application methods:

1. For Separator Coating

Separator-grade boehmite is used to coat polyolefin separators in lithium-ion batteries, significantly improving thermal stability and preventing thermal runaway.

• Market Insight: This segment accounts for over 65% of total demand currently. The material’s ability to maintain separator integrity at high temperatures (up to 300°C) makes it indispensable for EV battery safety.

• Trend: Battery manufacturers are increasingly specifying 99.95% and 99.99% purity grades for premium EV applications, driven by automaker requirements for enhanced safety margins.

2. For Electrode Coating

Electrode-grade boehmite is applied as a coating on cathodes or anodes to improve cycling stability and rate capability.

• Market Insight: While smaller than separator applications, this segment is growing faster as battery makers explore boehmite’s potential in high-nickel NMC and silicon anode systems.

• Trend: Development of specialized surface-treated boehmite products for electrode applications is creating new market opportunities, particularly for manufacturers offering application-specific solutions.

Segmentation by Application

The application landscape reflects the different battery types and their performance requirements where high purity boehmite delivers value.
