New Cobalt-Free Lithium-Ion Batteries
Researchers from the Cockrell School of Engineering at The University of Texas at Austin have a cobalt-free high-energy lithium-ion battery that reduces the costs of producing batteries while boosting performance in some ways. They have a new class of cathode that uses 89% nickel. Cathodes can make up roughly half of the materials costs for the entire battery, with cobalt being the priciest element. Cobalt is $28,500 per ton and it makes up 10% to 30% of most lithium-ion battery cathodes. “Cobalt is the least abundant and most expensive component in battery cathodes,” Manthiram said. “And we are completely eliminating

The Energy Central Power Industry Network is based on one core idea - power industry professionals helping each other and advancing the industry by sharing and learning from each other.
If you have an experience or insight to share or have learned something from a conference or seminar, your peers and colleagues on Energy Central want to hear about it. It's also easy to share a link to an article you've liked or an industry resource that you think would be helpful.
