Can Nikola Motor’s big battery promises be true?

Electric powered-truck maker Nikola Motor has endured a rollicking inventory marketplace entry this month soon after listing by an unusual reverse merger. The frenzy has been fueled in portion by the company’s statements that it will expose a new type of battery by the conclusion of this 12 months.

But even with the looming deadline, Nikola appears to even now be in the early stages of producing its battery. And even if Nikola succeeds in building a functioning variation, it could be as much as a 10 years prior to production begins.

Mainly because of the uncertainty, specialists are careful about the company’s promises. Quite a few very similar endeavours to commercialize new battery technological innovation in excess of the years have but to bear fruit.

Nikola founder and chairman Trevor Milton guarantees that his corporation will be capable to develop batteries at a charge of around $70 for each kilowatt-hour of storage capability. That would be a huge improvement around a lot more set up vehicle makers this kind of as Tesla and Volkswagen, which are nevertheless chasing the target of creating batteries for $100 per kilowatt-hour.

Cost per kilowatt-hour of vitality storage is a key factor in the final expense of electric autos, and their competitiveness with inside combustion automobiles. Estimates of the battery expense that would make electric passenger cars and trucks less costly to obtain and operate than gas-burners variety from $100 per kilowatt-hour down to $85 per kilowatt-hour.

Battery growth represents a substantial enlargement of scope for Nikola. The company’s planned flagship product is the Nikola 1, a lengthy-haul semi that uses liquid hydrogen, a gasoline that does not produce carbon emissions and can be produced working with renewable power. Nikola options to lease the vehicles and control substantially of the hydrogen offer chain, which includes building its possess fueling stations.

The corporation has however to market a solitary motor vehicle of any style, but its programs have been plenty of to catch the attention of almost $1.3 billion in enterprise funding from sources including European truckmaker CNH Industrial and German maker Bosch.

The pitch has proved even extra alluring to public investors. Nikola’s shares rose 136% concerning the June 4 reverse merger—a maneuver that avoids the lengthy preliminary community giving process— and June 9, when the company’s current market benefit briefly rose to $30 billion, bigger than Ford’s. By late on June 12, the inventory was down 21.7% from its peak.

“It is some bold promises that they’ve created,” claims Gene Munster of Loup Ventures, an trader concentrated on electric powered autos. “Now the clock begins ticking, due to the fact they have to provide.”

Building a much better battery isn’t simple

Nikola is not nonetheless revealing substantially about how it ideas to leapfrog rivals in battery technological know-how. But Milton suggests the goal is to reveal the battery ahead of the close of this yr at an as-however unscheduled function named Nikola Planet.

Milton did share a couple hints with Fortune.

The know-how wasn’t made by Nikola. As a substitute, Milton suggests, “we located some professors who experienced been operating on it for rather some time,” but declined to discover them. He did expose that the planned battery “has lithium, but it is not a lithium-ion [battery],” and that the design’s purpose is to “get rid of the cobalts, nickels, and magnesiums” — the metals that account for a lot of the expense of current battery know-how.

Primarily based on those details, Matthew McDowell, a battery resources researcher at Georgia Tech, speculates that Nikola may well be operating on what’s identified as a lithium-metallic battery. Broadly, the thought is to switch the graphite mesh that retailers lithium in today’s lithium-ion batteries with much more lithium, increasing strength density by 30% to 40%. That strategy is by now currently being aggressively pursued by a huge number of firms and scientists, McDowell states.

In contrast, James Frith, an analyst with the investigation organization Bloomberg New Strength Finance, believes Nikola might be developing lithium-sulfur battery know-how. Chris Robinson, an analyst with Lux Exploration, and Mihri Ozkan, an engineering professor and battery researcher at the University of California at Riverside, also agree that lithium-sulfur is the probably goal, based on the company’s claims.

Lithium-sulfur batteries are light-weight but bulky—a maybe great match for the significant vehicles that are the centerpiece of Nikola’s prepared item line. The technologies was patented in the early 1960s, and broad endeavours to commercialize lithium-sulfur batteries have been underway for extra than a ten years, including by startups like Oxis Energy. Those people commercialization endeavours have however to thrive, according to Ozkan, since of worries such as the protection and life span of lithium-sulfur batteries.

It’s unlikely that Nikola is keeping wraps on any radical, beforehand unidentified innovation in battery engineering, according to experts in the field.

“Progress in the battery sector doesn’t arrive from one big breakthroughs, but relatively continual advancements,” claims Robinson. “The odds an fully new chemistry—especially one particular as shut to commercialization as Nikola suggests—would slip earlier a multibillion-greenback business are slender to none.”

Whatsoever the tactic, Nikola is likely decades from generating a new variety of battery at scale. Despite its incredibly unique expense projections and programs to debut the engineering in six months, Nikola is nonetheless in the laboratory-testing section of improvement.

“In the lab we get a several thousand [charging] cycles, which is significantly superior than lithium-ion,” Milton suggests, referring to a critical measure of a battery’s longevity. “But the authentic planet is substantially distinctive from the lab…Now you’ve got to make them a great deal more substantial, [and] you have bought to abuse them” less than various temperatures, temperature, and use conditions.

Specialists agree that there is a significant big difference amongst the lab and the street. In point, optimistic promises about battery innovation primarily based on laboratory results are common—but lots of of these proposed technologies have still to be commercialized.

“It’s a genuinely complicated course of action,” suggests McDowell. “When you’re acquiring a battery technologies, there’s 15 or 20 diverse metrics you want to hit to have a responsible product. And they’re all intertwined.”

Those people metrics include not only efficiency underneath assorted temperature and weather circumstances, but also a battery’s daily life span, strength density, and the price at which it loses its demand when not in use.

Frith, of Bloomberg New Strength Finance, estimates that transitioning a new kind of battery from the lab to professional use usually takes 10 decades, or as tiny as 5 once operating prototypes are entire. Buyers will not have to hold out rather that extensive to know irrespective of whether Nikola can at some point fulfill its battery guarantees, while.

“We’ll know in 6 to 12 months whether [Nikola’s claims] are real or not,” claims Munster. In that time body, he says, the enterprise will want to clearly show it can establish a operating vehicle working with its battery, even if it hasn’t still attained industrial-scale output.

“It’s not going from the lab to 1% current market share. It’s heading from the lab to the road where people today can actually kick the tires,” states Munster. “And they have to have some proof that they developed it at the proper rate. That is the hurdle they will need to hit.”
