Common Motors Will Construct A US Battery Manufacturing facility With Samsung SDI


“Don’t put all of your eggs in a single basket!” my previous Irish grandmother preferred to say. The executives within the C Suite at Common Motors apparently had an previous Irish grandmother as effectively. Since GM first dipped a toe into the world of electrical autos, it has leaned closely on LG Chem — now often called LG Vitality Resolution — to provide it with batteries and way more. LG provided the batteries for the Chevy Bolt, but additionally a lot of the inside. Issues had been going swimmingly for the 2 corporations till the pesky battery fireplace schlamozzle, which put the way forward for the Bolt and its first cousin, the Bolt EUV, unsure for some time. In response to rumors, that fiasco price LG almost a billion {dollars}.

Nonetheless, the 2 corporations continued to maneuver ahead into the EV future collectively, with GM trumpeting claims concerning the superiority of its Ultium battery know-how which used pouch cells provided by LGES. Then in the beginning of this 12 months, cracks began appearing within the façade of company concord. GM instantly introduced that pouch cells had been out and cylindrical 4680 battery cells — a format pioneered by Tesla — had been in. GM on the time refused to specify simply precisely who would provide them.

My colleague Kyle Area launched CleanTechnica readers to the Tesla 4680 battery cell in September of 2020. He wrote that the brand new kind issue eliminates the tabs, will increase power density, maintains related thermal traits of smaller cells, improves the power-to-weight ratio, streamlines manufacturing, and lowers price.

Common Motors Chooses A Completely different Path

Till the 4680 battery information, GM was planning a fourth battery US battery manufacturing facility with LGES, however instantly, reviews from the media in South Korea hinted that The Common had put these plans on maintain and was casting about for a brand new battery companion. Now, GM and Samsung SDI have introduced they’ll construct that fourth US manufacturing facility collectively.

GM has but to make a proper announcement concerning the new manufacturing facility and Samsung SDI has deflected press inquiries, however Reuters says the 2 are anticipated to signal an settlement on Wednesday to construct the manufacturing facility in Michigan, in response to  a report by Korean media supply Yonhap. Samsung SDI is reviewing varied methods to cooperate with a number of automakers, however can’t touch upon any particulars, a Samsung SDI official instructed Reuters.

The Korea Herald, citing unnamed trade sources, reviews the 2 sides are present process final minute negotiations for particulars within the settlement such because the manufacturing quantity of the joint EV battery manufacturing facility, the funding technique and the situation of the plant. These don’t sound like particulars to us, however apparently the settlement to create an alliance between the 2 corporations is the necessary a part of the report.

The businesses are projected to interrupt floor for the joint manufacturing facility on the finish of this 12 months and it’s anticipated to start out producing prismatic and cylindrical battery cells in 2026. The capability of the collectively owned manufacturing facility is estimated to be between 30 and 50 gigawatt-hours per 12 months. 50 GWh is sufficient to produce about 600,000 electrical autos yearly. The price of the brand new manufacturing facility is claimed to be roughly $3.5 billion.

The GM partnership is Samsung SDI’s second joint venture in North America after the Korean battery maker introduced a plan to construct a $2.5 billion battery plant in Indiana with Stellantis final Could. The Indiana manufacturing facility is anticipated to start operation within the first quarter of 2025 with an annual manufacturing capability of 23 GWh.

The Korea Herald says this newest partnership between Common Motors and Samsung SDI demonstrates two trade traits. Battery makers don’t need to be locked in to just a few clients and car producers don’t need to be depending on only one battery provider. All of this exercise, after all, is being supercharged by the Inflation Discount Act, which offers important incentives to battery producers in the event that they construct batteries in the US in the event that they use battery supplies and parts sourced from authorized nations — i.e. not China.

LG Vitality Resolution, Korea’s main battery maker by gross sales quantity, has joined fingers with GM, Stellantis, Honda, Hyundai Motor Group, and Ford, whereas Samsung SDI now has partnerships with Stellantis and GM. One other Korean battery maker, SK On, is collaborating with Ford and Hyundai Motor Group.

The Cell Format Debate

The form and dimension of cylindrical battery cells have a direct impact on packaging and cooling — two components of significant concern to automotive corporations. Cells with bigger diameters have extra areas in between every one. Which will decrease the power density of a battery pack on a volumetric foundation, however it might additionally enable for higher cooling between particular person cells. But when these bigger cells are cheaper to fabricate, an automaker could want them even when they don’t seem to be the optimum form and dimension for squeezing as many cells as attainable right into a pack.

Within the remaining evaluation, it’s what’s contained in the cell that counts. There are as many cell chemistries as there are battery producers. Tesla just about invented the 4680 battery cell format, however is experimenting with totally different chemistries and manufacturing strategies to seek out the proper mixture of low prices, lengthy life, quick charging, good chilly climate efficiency, and excessive power density. It’s an ongoing course of that may proceed for many years to return, simply as inner combustion engine know-how has developed over the previous century. Each Common Motors and BMW made inline 6-cylinder engines, however they had been on reverse ends of the spectrum when it got here to energy and refinement.

A 12 months in the past, CATL, the world’s largest battery producer, launched its Kirin battery pack, which Wu Kai, chief scientist for CATL, stated has 13% extra energy than a battery pack utilizing 4680 cells. It’s not that the person battery cells are extra highly effective, it’s that CATL’s third era cell-to-pack know-how squeezes extra energy into the identical house occupied by a 4680 battery pack.

The key is within the packaging, not a brand new breakthrough in battery chemistry. Wu stated the Kirin battery leads the trade in system weight, power density, and volumetric power density. “Now we have analyzed the vary distribution of passenger vehicles within the final three years and located that customers’ quest for lengthy vary continues to be a development,” he added.

The Takeaway

The jockeying and jostling between battery producers and automakers will likely be fixed because the EV revolution strikes ahead. Spats between battery corporations will likely be frequent in addition to every seeks to achieve a aggressive benefit over its rivals. In 2021, LG Chem (because it was identified then) locked horns with SK Innovation over alleged commerce infractions. The 2 sides finally settled their variations, with SKI agreeing to pay a sum to LG that was roughly equal to the sum LG agreed to pay to GM. In the long run, there may be simply an excessive amount of cash to be made to get sidetracked by petty disputes. A billion paid over here’s a pittance in comparison with the billions to be revamped there.

The brand new association between Common Motors and Sansung SDI alerts that nobody needs to get caught with all their eggs in a single basket. My grandmother would agree.


I do not like paywalls. You do not like paywalls. Who likes paywalls? Right here at CleanTechnica, we applied a restricted paywall for some time, nevertheless it at all times felt mistaken — and it was at all times powerful to resolve what we must always put behind there. In principle, your most unique and finest content material goes behind a paywall. However then fewer individuals learn it! We simply do not like paywalls, and so we have determined to ditch ours.

Sadly, the media enterprise continues to be a troublesome, cut-throat enterprise with tiny margins. It is a endless Olympic problem to remain above water and even maybe — gasp — develop. So …
