The cells use far less cobalt and nickel and more manganese, claiming 33% more energy density than top lithium iron phosphate (LFP) cells at similar cost, targeted at full-size pickups and SUVs with 400+ miles of range starting in 2028. This builds on prior GM investments including $2.3B in 2021, $275M in 2022, and a $900M pilot line in Warren, Michigan. GM's battery chief suggested LFP may never enter GM's lineup, while European automakers Volkswagen and Stellantis are committing heavily to LFP production instead, betting on cheap cells over energy density. LG's research shows LMR cells retain 92.2% capacity after 883 cycles, addressing durability concerns, but manganese sourcing remains a challenge given the EU's near-total import dependence on the material. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is GM's plan for manganese-rich (LMR) battery cell production at Spring Hill? GM and LG Energy Solution are spending $1 billion to convert their Spring Hill, Tennessee plant into the first factory mass-producing prismatic lithium manganese-rich cells, with work starting in 2026 and finishing by 2028. The cells target full-size pickups and large SUVs with over 400 miles of range, with the first cars arriving in 2028. _daily.dev surfaces updates like this for engineers tracking EV battery chemistry shifts._ ### How does GM's manganese-rich battery cell compare to lithium iron phosphate cells? GM claims its lithium manganese-rich (LMR) cells deliver 33% more energy density than the best lithium iron phosphate cells at the same cost. LG Energy Solution's research also found the cells retained 92.2% of capacity after 883 cycles, addressing durability concerns, though manganese sourcing remains a separate supply chain issue. _Compare emerging battery chemistries like this on daily.dev before betting on one for a project._ ### Why are European automakers choosing lithium iron phosphate instead of manganese-rich battery cells? Volkswagen sold 49% of its Spanish battery venture to Gotion to produce lithium iron phosphate at Valencia, and Stellantis and CATL are building 50 GWh of LFP capacity at Zaragoza. Europe is betting that cheap cells matter more than dense ones because the cars built there are smaller, while GM is betting it can make dense cells cheap instead. _Follow diverging industry bets like this on daily.dev to spot which technology direction wins out._ ## Similar posts on daily.dev - [GM bets $900M on LMR battery chemistry to cut EV costs](https://daily.dev/posts/gm-bets-900m-on-lmr-battery-chemistry-to-cut-ev-costs-wrc7eop2b) · The Next Web · 0 upvotes · 0 comments - [Driving American battery innovation forward](https://daily.dev/posts/driving-american-battery-innovation-forward-3vv2jrgfl) · MIT News · 0 upvotes · 0 comments - [GM’s electric future depends on a new battery — and this building](https://daily.dev/posts/gm-s-electric-future-depends-on-a-new-battery-and-this-building-meyejxdfg) · TechCrunch · 0 upvotes · 0 comments - [LG’s experimental LMR cells held 92.2% of their energy after 883 cycles](https://daily.dev/posts/lg-s-experimental-lmr-cells-held-92-2-of-their-energy-after-883-cycles-n7riqjimo) · The Next Web · 0 upvotes · 0 comments - [GM Backs Sodium Ion Batteries for U.S. Grid Storage](https://daily.dev/posts/gm-backs-sodium-ion-batteries-for-u-s-grid-storage-wxac1rh13) · IEEE Spectrum · 0 upvotes · 0 comments --- Tags: [#supply-chain](https://daily.dev/tags/supply-chain) [View this post on daily.dev](https://daily.dev/posts/gm-will-spend-1b-making-the-first-manganese-rich-cells-in-mass-production-citnocr0r) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"GM will spend $1B making the first manganese-rich cells in mass production","url":"https://daily.dev/posts/gm-will-spend-1b-making-the-first-manganese-rich-cells-in-mass-production-citnocr0r","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/gm-will-spend-1b-making-the-first-manganese-rich-cells-in-mass-production-citnocr0r"},"datePublished":"2026-09-29T18:46:09.529Z","dateModified":"2026-09-29T18:46:30.087Z","description":"GM and LG Energy Solution are investing $1 billion to convert their Spring Hill, Tennessee plant into the first factory mass-producing prismatic lithium...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/c35fded8469a6a4425fe125d6d9ad17e?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/c35fded8469a6a4425fe125d6d9ad17e?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"The Next Web","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"The Next Web","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/tnw","url":"https://daily.dev/sources/tnw"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/gm-will-spend-1b-making-the-first-manganese-rich-cells-in-mass-production-citnocr0r","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"supply-chain","timeRequired":"PT3M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"The Next Web","item":"https://daily.dev/sources/tnw"},{"@type":"ListItem","position":3,"name":"GM will spend $1B making the first manganese-rich cells in mass production"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/gm-will-spend-1b-making-the-first-manganese-rich-cells-in-mass-production-citnocr0r#faq","mainEntity":[{"@type":"Question","name":"What is GM's plan for manganese-rich (LMR) battery cell production at Spring Hill?","acceptedAnswer":{"@type":"Answer","text":"GM and LG Energy Solution are spending $1 billion to convert their Spring Hill, Tennessee plant into the first factory mass-producing prismatic lithium manganese-rich cells, with work starting in 2026 and finishing by 2028.
