Li-ion batteries have demonstrated a great capability for meeting the needs of an ever-growing market of mobile technology. However, as these applications become more demanding more energy and power will be required from rechargeable Li-ion batteries. To meet these needs there are many R&D efforts ongoing to design and generate new materials capable of higher performance. In contrast to this approach, higher performance electrode materials could be achieved through surface-engineering of existing materials. Atomic Layer Deposition (ALD), a vapor phase deposition technique used to apply Angstrom thick layers of material on the surface of powders and objects, has been demonstrated to enable higher voltage cycling, longer cycle life, and increased safety, as well as improvements to the manufacturing process of Li-ion batteries. Historically ALD has been regarded as slow and expensive, however Forge Nano has developed a method for applying ALD coatings onto materials at low cost and high volume. In this work, Forge Nano demonstrates the ability to utilize ALD to enable significant improvements to Li-ion battery performance as well as reduce costs to produce batteries at scale.
