Lithium-ion batteries have become indispensable in hundreds of millions of finished products: smartphones, computers, cameras, electric cars... but how do they work and how will they evolve in the future?
Presented by Fred, Arkema's science communicator, this new Inside Materials educational video takes a close look at lithium-ion batteries: the materials they are made of, the innovations that improve their performance, but also their limitations and the next generations of batteries that will take over.
By the end of this video, you will know everything there is to know about electric batteries!
How is a lithium-ion battery made?
You will learn that a battery is an assembly of thousands of cells and that a cell—cylindrical, prismatic, or pouch, depending on the application—always combines a cathode, an anode, a separator, and an electrolyte to produce energy. Did you know that an electric vehicle battery pack can contain up to 9,000 cells?
What role do Arkema materials play in battery performance?
From Kynar® PVDF, used as a binder for active materials on cathodes or as a protective layer for separators, to Foranext® electrolyte salts, which accelerate recharging, and Graphistrength® carbon nanotubes, Arkema presents its innovations that improve range, service life, and charging speed.
How are lithium-ion batteries made safe?
The video explains how batteries are protected against overheating thanks to Proionic® ionic liquids, insulating polyimide polymers, and Bostik thermal adhesives that dissipate heat.
How are electric batteries recycled?
With the hydrometallurgical recycling process, more than 95% of the critical metals in black mass can be recovered using a clean process that utilizes Albone® hydrogen peroxide.
What will the batteries of the future be like?
Sodium, semi-solid, or solid batteries: the video explores these disruptive technologies that promise enhanced safety, ultra-fast charging times, and ranges of up to 1,000 km.
A clear, accessible video, perfect for understanding the technological challenges and the role of Arkema, which has become one of the world leaders in battery materials.
