How are Lithium-Ion Batteries made: Focus cathode materials

Explore the world of lithium-ion batteries (LiB) with a deep dive into cathode materials. This course provides a comprehensive understanding of the journey from raw materials to finished battery, focusing on the crucial role of nickel, cobalt, and lithium.

Discover the mineral sources and mining stages of these essential elements. We'll examine the extraction metallurgy processes used to obtain lithium, cobalt, and nickel from their ores, covering both pyrometallurgy and hydrometallurgy techniques. Learn the detailed processing involved in creating the final cathode material.

This course covers the synthesis and assembly of common cathode materials like LCO (Lithium Cobalt Oxide), NMC (Nickel Manganese Cobalt Oxide), and NCA (Nickel Cobalt Aluminum Oxide). You'll gain insights into the complete battery assembly process, from electrode preparation and assembly with anode and separator to winding, electrolyte filling, and initial charging.

A significant portion of the course is dedicated to recycling lithium-ion batteries. We'll explore the battery life cycle and various recycling flowsheet methods for both small and large batteries.

Key topics include:

• Mining Operations: Understand the processes involved in extracting ores, including crushing and screening and froth flotation.
• Extractive Metallurgy: Delve into the extractive metallurgy of cobalt and nickel, including leaching, electrowinning, and solvent extraction for obtaining pure metal salts.
• Lithium Refining: Learn about lithium resources and the processing of brines and lithium ores.
• Cathode Material Synthesis: Master techniques like coprecipitation, lithiation, calcination, and cathode refining to prepare high-quality cathode materials.
• Battery Assembly: Gain a practical understanding of assembling batteries, including electrode preparation and electrolyte filling.
• Battery Recycling: Explore the different methods and processes used in LiB recycling.

This course is designed for those seeking a detailed understanding of nickel, cobalt, and lithium extractive metallurgy and cathode material preparation. It's not focused on electrochemistry or battery performance, but rather the materials science and engineering behind LiB components.

Backed by over 10 years of experience in battery research and industry, including 20 years of chemistry research, this course offers a reliable and in-depth guide to creating LiB cathode materials. We'll provide a wealth of resources, including literature, websites, and books, to support your continued learning.
