Although still practically useful, LFP has only about half the energy density of cobalt and nickel batteries. Another appealing option are organic materials, but so far most of these materials have not been able to match the conductivity, storage capacity, and lifetime of cobalt-containing batteries.
With the electric vehicle (EV) industry gaining momentum, the role of cobalt in EV batteries has come under intense scrutiny and spurred innovation. Cobalt, a critical component in many lithium-ion EV batteries, offers numerous advantages but also poses environmental, ethical, and cost-related challenges.
l Lithium-Titanate (Li-Ti) Batteries: Li-Ti batteries, specifically lithium titanate, are another cobalt-free option. They are known for their fast charging capabilities, long cycle life, and good performance at low temperatures, albeit with slightly lower energy density compared to other lithium-ion batteries.
Now, researchers in ACS Central Science report evaluating an earth-abundant, carbon-based cathode material that could replace cobalt and other scarce and toxic metals without sacrificing lithium-ion battery performance. Today, lithium-ion batteries power everything from cell phones to laptops to electric vehicles.
Cobalt's role in enhancing energy density and ensuring stability in lithium-ion batteries is indisputable. These batteries rely on the movement of lithium ions (Li+) between the anode and the cobalt-containing cathode. And cobalt serves multiple vital functions:
The new battery also has comparable storage capacity and can be charged up faster than cobalt batteries, the researchers report. “I think this material could have a big impact because it works really well,” says Mircea Dincă, the W.M. Keck Professor of Energy at MIT.
