GM Expands Battery Ambitions with Sodium-Ion Expertise That May Finally Profit Future EVs : Automotive Addicts

Basic Motors is broadening its battery technique as soon as once more, saying plans to develop sodium-ion battery cells by a brand new partnership with vitality storage startup Peak Power. Whereas the information might not instantly sound related to electrical automobiles, the long-term implications might be vital for GM’s future EV lineup. The corporate says the brand new chemistry will initially be used for large-scale stationary vitality storage programs, however the analysis and manufacturing experience gained by the hassle may assist speed up battery innovation and decrease prices throughout its whole electrification portfolio.

At first look, sodium-ion batteries would possibly seem to be an uncommon route for an automaker centered on EV development. In contrast to the lithium-based batteries utilized in right now’s electrical automobiles, sodium-ion expertise affords decrease vitality density, making it much less sensible for passenger automobiles the place maximizing driving vary is vital. As a substitute, GM sees a chance in vitality storage programs that assist utilities, renewable vitality initiatives, knowledge facilities, and different infrastructure purposes the place bodily dimension is much less of a priority.

In response to an unique interview performed by Automobile and Driver with GM Vice President of Battery and Sustainability Kurt Kelty and veteran battery engineer Andy Oury, sodium-ion chemistry brings a number of compelling benefits. Sodium is each considerable and cheap, and maybe extra importantly, the provision chain will not be closely depending on Chinese language-controlled supplies and processing networks. At a time when governments and producers are more and more centered on provide chain safety, that benefit may change into extraordinarily useful.

The expertise additionally affords distinctive operational advantages. Sodium-ion batteries are way more tolerant of warmth and chilly than many lithium-based options, decreasing the necessity for classy cooling programs. For big stationary battery installations anticipated to function for twenty years or longer, that simplicity can dramatically scale back upkeep necessities and lifelong working prices. These benefits make sodium-ion a lovely possibility for vitality storage initiatives even when it stays unsuitable for mainstream electrical automobiles right now.

GM’s present EV portfolio already depends on a number of battery chemistries. Most of its electrical fashions from Chevrolet, GMC, and Cadillac make the most of nickel manganese cobalt aluminum cells produced by the corporate’s Ultium partnership with LG Power Answer. The upcoming next-generation Chevrolet Bolt will use lithium iron phosphate batteries, whereas GM can be investing closely in lithium manganese-rich expertise, generally known as LMR, which it believes may mix decrease prices with increased vitality density for future electrical vehicles and SUVs.

The addition of sodium-ion successfully offers GM a fourth battery chemistry to develop concurrently. Whereas that will sound like a sophisticated method, firm executives consider it creates alternatives to speed up studying and enhance battery improvement throughout the board. Classes discovered from one chemistry usually translate into enhancements in manufacturing processes, testing strategies, and manufacturing efficiencies that may profit different battery applications.

A significant piece of that technique is GM’s newly opened Battery Cell Growth Heart in Warren, Michigan. The ability serves as a bridge between laboratory analysis and full-scale manufacturing, permitting engineers to refine manufacturing strategies earlier than handing them off to business battery companions. Mixed with GM’s Wallace Battery Cell Innovation Heart, the corporate now has almost 800,000 sq. ft devoted to advancing battery expertise.

Kelty informed Automobile and Driver that the brand new improvement heart may shorten the timeline required to carry promising battery applied sciences to market by as a lot as a yr. That accelerated course of is especially necessary for rising chemistries resembling LMR and sodium-ion, each of which nonetheless have vital room for enchancment in comparison with extra mature battery applied sciences. Whereas conventional lithium-ion batteries have seen many years of optimization, GM believes the best future positive factors might come from these newer options.

For EV fans hoping sodium-ion batteries would possibly quickly energy reasonably priced electrical automobiles, GM’s management was clear within the Automobile and Driver interview. The corporate doesn’t see sodium-ion turning into viable for EV purposes within the quick or medium time period because of its decrease vitality density. As a substitute, GM stays centered on advancing LMR expertise, which is anticipated to enter quantity manufacturing round 2028 and will play a serious position in decreasing the price of bigger electrical automobiles.

Maybe probably the most intriguing takeaway from GM’s newest battery announcement is what wasn’t stated. Through the unique interview, firm executives declined to debate whether or not future automobile architectures are being developed alongside these new battery applied sciences. With opponents pursuing next-generation EV platforms geared toward dramatically decreasing prices, it’s troublesome to think about GM standing nonetheless. For now, the automaker is holding these plans underneath wraps, however its rising funding in battery innovation suggests there could also be a lot larger developments ready within the wings.
