Is It End For Lithium’s Reign As Battery King?

Lithium-ion batteries power the world around us. Their prevalence in our daily life is growing steadily, to the extent that lithium-ion batteries now power a whopping 70 percent of all rechargeable devices.

From electric vehicles to smartphones to utility-scale energy storage, lithium-ion batteries are increasingly forming the building blocks of innumerable sectors.

But despite its dominance in battery technologies, there are some serious issues with lithium supply chains that make it a less-than-ideal model upon which to base our world.

Not only is extracting lithium often extremely environmentally damaging, it’s deeply intertwined with geopolitical pressure points. China controls a huge portion of global lithium supply chains, rendering markets highly vulnerable to shocks and the political will of Beijing.

China’s control is particularly strong in the case of electric vehicle batteries, thanks to a decade-long strategy to outcompete the globe.

“For over a decade, China has meticulously orchestrated a strategic ascent in the global electric vehicle (EV) batteries market, culminating in a dominance that now presents a formidable challenge to Western manufacturers,” reports EE Times.

The effect functions as “almost a moat” around Chinese battery production, buffering the sector against international competition.

The multiple downsides and risks associated with lithium and lithium-ion battery sourcing is pushing EV companies to research alternative battery models to power the electric cars of the future.

There are a litany of lithium alternatives in research and development phases, including – but not limited to – lead, nickel-cadmium, nickel-metal hydride, sodium nickel chloride, lithium metal polymer, sodium-ion, lithium-sulfur, and solid state batteries.

Solid state batteries seem to be the biggest industry darling. Solid-state batteries use a solid electrolyte as a barrier and conductor between the cathode and anode.

These batteries don’t necessarily do away with lithium, but they can eliminate the need for graphite – another critical mineral under heavy Chinese control. Plus, solid state batteries are purported to be safer, have higher energy density, and recharge faster than lithium-ion batteries.

While solid-state batteries are still in development, they’re already being tested in some applications by car companies. Mercedes and BMW claim that they are already road-testing vehicles powered by solid-state batteries, but it will likely be years before we see them in any commercial context.

Subaru is on the verge of testing solid-state batteries within its vehicles, but is already employing a smaller form of the technology to power robots within its facilities.

However, while solid-state batteries are being hailed as a sort of holy grail for battery tech, some think that the promise – and progress – of solid-state batteries is overblown.

“I think there’s a lot of noise in solid state around commercial readiness that’s maybe an exaggeration of reality”, Rivian CEO RJ Scaringe said during an interview on this week’s Plugged-In Podcast.

Sodium ion batteries are also a promising contender to overtake lithium-ion batteries in the EV sector. Sodium is 1,000 times more abundant than lithium.

“It’s widely available around the world, meaning it’s cheaper to source, and less water-intensive to extract”, stated James Quinn, the CEO of U.K.-based Faradion. “It takes 682 times more water to extract one tonne of lithium versus one tonne of sodium.That is a significant amount.”

Bloomberg projections indicate that sodium-ion could displace 272,000 tons of lithium demand as soon as 2035.

But even this does not signal the death of lithium. Lithium is simply too useful in battery-making. It’s energy-dense and performs well in cold weather, making it “indispensable for high-performance applications” according to EV World.

“The future isn’t lithium or sodium—it’s both, deployed strategically across sectors…the result is a diversified, resilient battery economy.”
