Coating Cathode Materials in Batteries with Spatial ALD

Cathode materials

Cathode-active materials (CAM) are typically composed of metal oxides. The main types are lithium cobalt oxide, lithium manganese oxide, lithium iron phosphate, and lithium nickel manganese cobalt oxide. Each of these has different levels of how much energy they can hold, how well they handle heat, and how cost-effective they are.

Cathodes are central to battery functionality, determining energy density and performance across various applications. Their ability to store and release energy efficiently impacts the reliability and effectiveness of batteries used in devices, vehicles, and renewable energy systems.

Advancements in battery technology have been influenced by Spatial Atomic Layer Deposition (sALD). This thin film layer technique is reshaping cathode material development by offering precise and scalable methods, promising advancements in battery lifespan.

Significance of Coating Cathodes in Battery Production

Coating cathodes is vital in optimizing battery performance. These coatings act as protective layers, shielding cathode materials from degradation, enhancing conductivity, and ensuring long-term stability. A well-coated cathode can significantly reduce the capacity fade in a lithium ion battery.

Limitations of Traditional Cathode Coating Methods

Traditional coating methods often suffer from inconsistencies in layer thickness, restricted material choices, and challenges in scaling production. These limitations have underscored the need for innovative techniques using Spatial ALD to overcome these drawbacks of cathode performance.
