If you’ve ever paused to think about where the power in your phone, electric car, or home solar panel comes from, chances are you’ve focused on performance, cost, or range. But for me, as someone who’s spent the last seven years building and scaling low carbon emission batteries (LCEBs) for a living, the first question I ask isn’t “how well does this battery work?” It’s “how much carbon did it take to make?” Low Carbon Emission Batteries
I got into this line of work back in 2016, when my neighbor traded his gas-guzzling pickup for a used electric SUV—only to tell me a few months later that he felt like he’d swapped one carbon footprint for another. “That battery was made in a factory that runs on coal,” he said. “It’s still worse than my old truck for the first two years I drive it.” That stuck with me. Back then, most battery tech companies were racing to cram more energy into smaller, cheaper cells, but almost no one was looking at the carbon cost of building them—a number we now call cradle-to-gate emissions. For lithium-ion batteries, which power 90% of today’s electric vehicles and grid storage, those emissions aren’t trivial: traditional manufacturing can generate 100 to 180 kilograms of carbon dioxide equivalent (CO₂e) per kilowatt-hour (kWh) of battery. For a 75 kWh car battery, that’s 7.5 to 13.5 tons of emissions before it ever leaves the factory. That’s where low carbon emission batteries come in—and why they’re not just a “green upgrade” but a core part of actually fighting climate change.
Let’s start with what makes an LCEB different. It’s not just a battery that doesn’t pollute when it’s in use. It’s a battery where every step of its lifecycle has had its carbon footprint cut: from mining raw materials, to processing and manufacturing, to even end-of-life recycling. Let’s break that down, because this is where the real science happens—and where I’ve spent most of my time.
First, raw materials. The biggest carbon hit in battery production comes from processing lithium, cobalt, and nickel, and that’s mostly because those steps use a lot of energy. Traditional lithium refining, for example, often relies on fossil fuel-powered facilities that burn coal or natural gas to heat and process lithium ore. Last year, a study from the International Energy Agency (IEA) found that refining lithium alone makes up 22% of a standard battery’s cradle-to-gate emissions. LCEBs fix that two ways: we source our lithium from mines that use geothermal or hydropower for refining, not coal, and we’ve partnered with two Australian lithium producers that use direct lithium extraction (DLE) technology, which uses 70% less water and 40% less energy than traditional brine or hard-rock processing. For cobalt, which is almost exclusively mined in the Democratic Republic of Congo, we only work with artisanal and small-scale miner cooperatives that run solar-powered processing facilities, not the fossil fuel-heavy refineries that dominate the market. Cutting energy use in raw material processing alone can knock 35% off a battery’s upfront carbon footprint.
Next, manufacturing. This is the step where most batteries are actually built, and it’s another huge source of emissions. Traditional battery factories often run on grid electricity that’s 40% fossil fuel, per U.S. Energy Information Administration (EIA) data. That means every kWh of a battery made in a grid with high coal use adds more emissions to its total. Our factories are powered 100% by on-site solar and wind, with battery storage that lets us run 24/7 without drawing from the grid’s fossil fuel mix. We also use what’s called dry electrode coating, a process that cuts energy use in cell manufacturing by 50% compared to the traditional wet coating method, which relies on toxic solvents and energy-intensive drying ovens. I’ve visited factories that pump millions of liters of solvent waste into local rivers while heating their cells with natural gas, and that’s not just bad for the planet—it’s unnecessary. Our dry coating process eliminates that waste entirely. The result? Our LCEBs have an average cradle-to-gate emission of just 35 kg CO₂e per kWh. For that same 75 kWh car battery, that’s only 2.6 tons of emissions before it’s even installed—less than a third of the industry average.
But here’s the part most people miss: LCEBs don’t stop at low upfront emissions. The real win comes when you compare their total lifecycle footprint to traditional batteries, and how they pair with low-carbon systems. Let’s take that electric SUV my neighbor bought. If he’d used a standard battery, that 13.5 tons of upfront emissions would mean he’d have to drive the car for about 20,000 miles to offset that carbon from the factory, even if he charged it on the grid. With our LCEB, that upfront footprint is 2.6 tons. If he charges that car on a grid that’s 80% renewable (which is common in states like California or countries like Norway), he offsets that 2.6 tons in just 3,500 miles. Suddenly, he’s not trading one carbon problem for another—he’s cutting emissions from day one.
That same logic applies to grid storage, which is another big part of LCEBs’ impact. Last year, a utility in Texas installed a 100 MWh battery farm made with our cells to pair with their new wind farm. Before that, they were running a natural gas peaker plant to cover gaps when the wind wasn’t blowing. A study we did with a third-party environmental group found that using our LCEBs cut the project’s total emissions by 42% compared to using standard batteries, because of the lower upfront footprint. Over the 15-year life of the farm, that adds up to almost 15,000 tons of avoided emissions—equivalent to taking 3,200 gas cars off the road for a year. And because LCEBs last longer too? Wait, no—actually, the longer you use a battery, the more you spread out its upfront emissions. Our batteries are designed to cycle 6,000 times, compared to the industry average of 4,500. That means a 10-year life instead of seven, so all that carbon we spent on making the battery is spread over more years of powering clean energy.
Another key part of LCEBs is recyclability. Traditional batteries are hard to break down, and only 5% of lithium is recycled globally, according to the IEA. Most end up in landfills, where they leach toxic metals and waste all that embedded carbon that went into making them. We’ve built a closed-loop recycling program for our LCEBs: when a battery reaches the end of its life (15 years for EVs, 20 for grid storage), we take it back, use hydrometallurgical processing to recover 95% of lithium, nickel, and cobalt, and those metals go straight into making new LCEBs. That cuts the need for new raw materials, and cuts the carbon footprint of a new battery by another 20%—because recycled metals have a way lower carbon cost than mined ones. Last year, we recycled 12,000 tons of old batteries, and that saved almost 4,000 tons of CO₂e from new mining and processing.
I know what some skeptics will say: “Is this just greenwashing? Is a low carbon emission battery actually different from any other battery?” Let’s get specific. We don’t call our batteries LCEBs lightly. Every cell we make has a third-party verified carbon footprint label, right on the datasheet. You can pull up a report that shows exactly how much carbon was emitted in mining the lithium, how much energy was used in refining, how much solar was used in the factory, and how much was recycled at the end. No fine print, no vague claims. That transparency is non-negotiable for me, because the last thing we need in the battery space is more companies overstating their environmental benefits.
We’ve worked with small EV startups, major automakers, and utility companies across North America and Europe, and the feedback has been consistent: they want to hit their 2030 net zero targets, but standard batteries are a huge barrier. A European carmaker told us last year that switching to LCEBs let them declare their new electric model as “net zero from cradle to well” two years ahead of their original schedule. A solar installer in Hawaii found that using our LCEBs for residential storage cut their customers’ total household carbon footprint by 30%, compared to using standard batteries paired with rooftop solar.
That’s the real value of LCEBs: they’re not a niche product for eco-conscious buyers. They’re a necessary tool to make the transition to clean energy actually work. Right now, batteries are one of the fastest-growing sources of industrial emissions. If we keep making them with coal-powered factories and fossil-fueled raw material processing, we’ll hit our climate targets faster. But if we build LCEBs that cut upfront emissions by 70% or more, and pair them with renewable energy, we can turn battery production from a climate problem into a climate solution.
I started this business because I hated the idea that people had to choose between buying clean tech and reducing their carbon footprint. For too long, the narrative has been: “Get an EV, but don’t ask where the battery came from.” Or “Put solar panels on your roof, but the battery that stores that power is dirty.” LCEBs blow that narrative apart. They’re proof that you can build a high-performing battery, scale it affordably, and still prioritize the planet.

We’ll send you a third-party verified footprint for any of our cells, walk you through how LCEBs fit into your net zero plan, and help you calculate exactly how much carbon you’ll avoid by switching. The transition to clean energy isn’t just about wind turbines and solar panels. It’s about every part of the system, including the battery that powers it. And that part doesn’t have to leave a big carbon footprint—if you choose the right battery.
