TDK Ventures, a unit of TDK, is investing in Novalith, a startup specializing in lithium extraction, stated Anil Achyuta, managing director at TDK Ventures.

Novalith’s technological options seize and make the most of carbon dioxide from the environment to isolate and extract lithium of a better high quality from useful resource deposits, with no detrimental by-products, to supply a battery-grade, high-purity Li2CO3. The method makes use of much less water, requires a smaller infrastructure and is more cost effective than the present business customary. Novalith is commercializing its patented LiCAL expertise for lithium extraction and refining from lithium ores, akin to spodumene and clays.

In an interview with EE Occasions, Achyuta famous that each one battery chemistries (NMC, LFP, strong state, silicon anodes, and many others.) require lithium as the important thing aspect, and lithium demand is predicted to extend by 10× by 2040.

Projected demand for battery-grade lithium was anticipated to outpace provide by 2023, with greater than a 9× enhance by 2030, in keeping with analysts, pushed specifically by a worldwide pattern towards electrification. In response, the curiosity in lithium-production improvements is meteoric, because the business seems to take care of a viable battery provide chain.

“Nonetheless, the business provide has persistently failed to satisfy the market want,” Achyuta stated. “The present provide is just 400,000 tpa [tons per annum], however the want will develop to ~4 million tpa in 10 years. Novalith, by offering a clear and quick direct lithium-extraction expertise, will be capable to tackle 1.5 million tpa of lithium from spodumene, clay and different rock sources.

“The latest Inflation Discount Act has listed phrases that restrict electric-vehicle OEMs to make use of the uncooked materials extracted, processed and recycled from China and offers incentives for constructing processing and manufacturing vegetation in North America and U.S. FTA companions,” he added. “The IRA is driving an enormous shift out of the availability chain that we’re counting on now. We consider Novalith will profit from the brand new coverage drive and the business provide chain shift and supply a leapfrog resolution to construct a brand new, clear, low-carbon–footprint provide chain for the pressing want of electrification.”

As well as, the present carbon-intensive output from each processes’ equipment bills and different hazardous by-products (such because the chemical compounds utilized in brine resolution) negates the environmental accountability that lithium-ion batteries have been designed to advertise within the first place, making Novalith’s new expertise much more compelling.

Applied sciences and developments

In accordance with TDK Ventures, the approach developed by Novalith not solely helps all lithium-battery–powered objects function extra cost-effectively but in addition makes certain that the applying and material-sourcing processes in an electrified society are ecologically helpful. The provision chain for “soiled” supplies utilized in battery manufacture has been a contentious subject and is seen as the primary critique of the electrification motion as an entire.

Present manufacturing strategies wrestle when it comes to time, price and environmental influence. Commonplace practices embrace both:

  • Conventional ore mining that’s requiring the age-old arduous strategy of discovering lithium-containing ore deposits
  • Brine extraction, which makes use of monumental quantities of water and chemical compounds to gather lithium dissolved in pooled liquid deposits beneath the earth or in tailing ponds.

In accordance with TDK Ventures, each approaches are extremely sluggish and full of upfront infrastructure prices.

“What the business is doing proper now could be delivery spodumene focus from Australia to China and placing it by way of the normal means of lithium chemical processing [the sulphuric acid process],” Achyuta stated. “This consists of roasting, sturdy acid leaching [and] tedious and prolonged impurity-removal processes to do away with silica, magnesium, calcium and different impurities, adopted up with filtration, purification, including soda ash for carbonization after which separation and conversion. The method is closely concerned with chemical compounds and regent, with excessive carbon emission and power consumption, plus a number of dangerous by-products and tailings, in addition to giant quantities of strong waste to landfill. Compared, Novalith’s technique has a a lot less complicated flowsheet that captures CO2, recycles water, produces no dangerous bulk by-products and is a quick and cost-effective solution to manufacture battery-grade lithium carbonate or lithium hydroxide. In contrast with the standard course of, Novalith’s expertise has important advantages, together with >50% price discount on processing and tools, utilizing 90% much less water, zero dangerous bulk waste and fewer than half of the emissions of the standard course of per ton of lithium chemical produced.”

Novalith and its processes.

TDK Ventures will totally help Novalith all through its growth journey, on expertise milestones, business progress, future fundraising and firm progress.

In accordance with Achyuta, this consists of serving to them to construct their crew; rent key expertise, advertising and marketing and authorized, introducing them to different enterprise tractions and partnership alternatives; and serving to increase the following spherical with high monetary enterprise capitalists (VCs) and techniques to supercharge the crew and firm as they speed up to the following degree.

“Moreover, we hope to offer help past capital and greater than what VCs often may do; that is what we [mean when we] speak about TDK goodness and leveraging TDK as a worldwide giant firm dedicated to a cleaner future,” Achyuta stated. “We are going to facilitate the engagement and collaboration between Novalith and TDK, and with certainly one of TDK’s companies in battery manufacturing, TDK could possibly be a possible future off-taker of Novalith merchandise, and we’d like to be the primary witness and help Novalith because the startup grows and strikes forward.”

Novalith’s expertise originated in a college laboratory. Whereas scaling up from a lab breakthrough to commercial-scale functions, Novalith’s expertise might want to undergo the educational cycle, very like many different early-stage corporations.

“However now we have a number of confidence within the crew: The CEO and founder, Steven Vassiloudis, is totally devoted to carrying this formidable mission along with Novalith’s main scientists and engineering crew to proceed growing and de-risking the expertise as they construct pilot, demo and future business vegetation step-by-step,” Achyuta stated. “The bottom line is pace. We hope to offer all of the help that Novalith must speed up the expansion of the corporate—and in addition hope to work with different business companions. This isn’t solely our mission for Novalith however our widespread purpose to decarbonize the mining and processing business and speed up the pace of electrification.”

Globally, 30 Mt of lithium (~160 Mt of lithium carbonate equal) are rock-based lithium (~70% arduous rock, ~30% delicate rocks like clays) that must be extracted and processed in a cost-effective, quick and inexperienced means.

“We see Novalith proceed to progress and validate their expertise with extra lithium sources from numerous arduous rock and clays,” Achyuta stated. “Given the projected annual demand [~4 Mtpa LCE and current annual production of ~0.5 Mt LCE], Novalith would be capable to unlock an extra 1.5 Mt LCE each year of lithium manufacturing. Novalith’s modern expertise is a game-changer for the lithium provide chain and will convey a >50% price discount on processing and tools, considerably scale back water consumption, produce no dangerous bulk waste and produce a lithium chemical with lower than half of the emissions per ton in contrast with lithium produced by the standard course of.”


There are projected to be 2 billion EVs desired by 2050 to satisfy the net-zero purpose, which might then drive a requirement for 264 billion kilos of extracted lithium, in keeping with Achyuta.

“Not solely will lithium manufacturing have to ramp up—by an element of 10 or extra over the following 20 years—however extraction strategies should change into extra environment friendly to make EV batteries extra reasonably priced and to leverage lithium deposits that aren’t presently economically viable,” he stated. “In response to this international imbalance of provide and demand, additional exacerbated by the extremely brief timeline driving progress, many EV OEMs have adopted a method integrating in-house battery-manufacturing gigafactories into their provide chains to scale back threat related to provide.”

In consequence, lithium miners are beneath extra pressing stress to satisfy demand. Thus, the timetables for lithium provide are actually a significant business ache level along with long-term uncooked materials availability.

Constructing a lithium mine requires between 5 and 10 years, in keeping with Simon Moores, CEO of Benchmark Mineral Intelligence. A battery facility could also be in-built about 24 months. These two provide chain elements don’t share a typical timeline.
