Scientists have developed a long-lasting battery made with nickel.
The discovery could reduce or even eliminate the use of cobalt in the batteries that power electric cars and other products.
Cobalt is often mined using child labor.
โNickel doesnโt have child labor issues,โ says Huolin Xin, professor of physics and astronomy at the University of California, Irvine.
The method could usher in a new, less controversial generation of lithium-ion batteries.
Until now, nickel wasnโt a practical substitute because large amounts of it were required to create lithium batteries, Xin says. And the metalโs cost keeps climbing.
To become an economically viable alternative to cobalt, nickel-based batteries needed to use as little nickel as possible.
โWeโre the first group to start going in a low-nickel direction,โ Xin says. โIn a previous study by my group, we came up with a novel solution to fully eliminate cobalt. But that formulation still relied on a lot of nickel.โ
To solve that problem, Xinโs team spent three years devising a process called โcomplex concentrated dopingโ that enabled the scientists to alter the key chemical formula in lithium-ion batteries as easily as one might adjust seasonings in a recipe.
The doping process, Xin explains, eliminates the need for cobalt in commercial components critical for lithium-ion battery functioning and replaces it with nickel.
โDoping also increases the efficiency of nickel,โ says Xin, which means EV batteries now require less nickel to workโsomething that will help make the metal a more attractive alternative to cobalt-based batteries.
Xin says he thinks the new nickel chemistry will quickly start transforming the lithium-ion battery industry. Already, he says, electric vehicle companies are planning to take his teamโs published results and replicate them.
โEV makers are very excited about low-nickel batteries, and a lot of EV companies want to validate this technique,โ Xin says. โThey want to do safety tests.โ
The study appears in the journal Nature Energy.

It comes as no surprise that the chairs and table that make up the Doodle Collection are each one-of-a-kind. Designed by Leah Ring for her studio, Another Human, each piece of furniture resembles a blind contour drawing brought to life in three dimensions. Chaos, asymmetry, and an organic process were all welcomed in creating these unique pieces. Each features linework made of nickel-plated steel thatโs been hand-bent and welded together, and the table includes a gravity-defying resin top. Ring describes the process of making the Doodle Collection as โfree and exploratoryโ and different from past furniture pieces released through Another Human.

Coil + Drift have recently relocated to Upstate New York, opening their doors to a new 3000-square-foot studio within the Catskill Mountains. Nestled two hours north of New York City, the space houses an office, showroom, and state-of-the-art production facility where all of Coil + Driftโs lighting fixtures are now produced by their in-house production team.
Founder and designer John Sorensen-Jolink established Coil + Drift in New York City back in 2016, but in 2021, moved the studio to the Catskill Mountains to immerse the team in the wild landscape that inspires much of his material-forward designs. A former dancer-turned-designer, Sorensen-Jolink designs objects that are grounded in human connection and spacial awareness, with a deep reverence for nature.
Visitors to their new studio showroom can view a series of new additions to Coil + Driftโs existing collection. The highly popular YAMA table lamp is now available as a floor lamp in a new tarnished nickel finish. The Atlas series has also been expanded to include a new mobile-like chandelier, and the June Floor Mirror has been introduced in a new ebonized maple finish.
