BESS Supply Chain Risks, GM’s LMR & Sodium-Ion Strategy, 370 GWh Chinese Capacity, and $20 B Investment (2021 to 2026)
BESS Supply Chain Risk, GM LMR and Sodium-Ion Adoption
The extreme concentration of the lithium-ion battery supply chain within China created a critical geopolitical risk, forcing Western automakers like General Motors (GM) to accelerate development of alternative chemistries like Sodium-Ion (Na-ion) and Lithium Manganese-Rich (LMR) to secure future production.
- Between 2021 and 2024, China solidified its market position, producing three-quarters of all lithium-ion batteries and controlling 70% of production capacity for cathodes and 85% for anodes. During this period, GM‘s primary battery strategy was to build a domestic, lithium-ion supply chain centered on its Ultium platform, with a target of 160 GWh of cell capacity.
- By 2025-2026, this supply chain risk materialized into strategic action. GM confirmed it was developing proprietary LMR and Na-ion prototypes as a direct response to projections that China would control over 95% of the global sodium-ion manufacturing capacity by 2030, effectively creating a new dependency.
- This strategic pivot is now two-pronged: GM is targeting its Na-ion prototypes for grid-scale storage, where low cost and cycle life are paramount, while positioning its LMR technology as a direct, US-built competitor to the Chinese-dominated Lithium Iron Phosphate (LFP) batteries used in affordable EVs.

$20 B in Global Investment, Sodium-Ion Capacity Expansion
Over $20 billion in announced global investment has poured into the sodium-ion sector, yet this capital is overwhelmingly concentrated in China, creating a formidable first-mover advantage and a high barrier to entry for Western firms.
- Before 2025, significant capital injections were signaled by deals like Reliance Industries‘ acquisition of UK-based technology leader Faradion for £100 million in late 2021, highlighting industrial interest in securing sodium-ion intellectual property.
- By 2026, the scale of investment had resulted in a tracked global production capacity pipeline of 370 GWh for sodium-ion cells, with nearly all of it located in China, demonstrating an established and rapidly scaling manufacturing ecosystem.
- This contrasts sharply with the US market, where battery project announcements saw $11 billion in cancellations during 2025, reflecting market volatility and the difficulty Western companies face in securing long-term capital for new battery chemistries amid shifting government policies.

GM 0 Sodium-Ion Partnerships vs Chinese JVs (2021 to 2026)
While Chinese firms like BYD and CATL aggressively formed joint ventures to build a dominant sodium-ion market, GM‘s partnerships through 2026 remained focused on securing its existing lithium-ion supply chain, highlighting its late-mover status in sodium-ion collaborations.
- In November 2023, BYD announced a major joint venture with Huaihai Holding Group with the explicit goal of becoming a world leader in the production of sodium-ion batteries, signaling a strategic push to build an ecosystem around the technology.
- In contrast, GM’s key collaborative agreement during this period was a June 2023 supply deal with Element 25. The partnership was designed to secure manganese sulfate for its lithium-ion Ultium battery cathodes, not for developing alternative chemistries.
- This divergence demonstrates two different strategies. Chinese players used partnerships to rapidly build and control a new manufacturing ecosystem, whereas GM‘s efforts in alternative chemistries appear to be primarily internal R&D, lacking the external alliances needed for rapid scaling.

| Partner / Project | Time Frame | Details and Strategic Purpose | Source |
|---|---|---|---|
| BYD / Huaihai Holding Group | Nov 2023 | Formation of a joint venture to establish a world-leading production base for sodium-ion batteries. This strategic alliance is designed to accelerate mass commercialization and secure market leadership in China. | Yahoo News |
| General Motors / Element 25 | Jun 2023 | GM agreed to help finance a new manganese sulfate facility in Louisiana to secure supply for its lithium-ion Ultium batteries. The partnership shores up its existing supply chain rather than building a new one for alternative chemistries. | General Motors |
China vs US, GM Sodium-Ion Geographic Focus
China established itself as the undisputed global hub for sodium-ion manufacturing and capacity between 2021 and 2026, while the United States’ efforts, including GM‘s development, are positioned as a strategic, domestic countermeasure rather than a play for global market share.
- Between 2021 and 2024, China’s dominance in the lithium-ion supply chain was solidified, with the country controlling critical processing steps, including 95% of graphite and 85% of processed cobalt.
- From 2025 to 2026, this pattern was replicated in the sodium-ion sector. Projections showed China would command a 95.9% share of the 122.9 GWh of global sodium-ion battery capacity by the end of 2025.
- The US response remains geographically defensive. GM’s R&D is concentrated in its US labs, and its partnerships aim to build a US-based supply chain, such as the manganese facility in Louisiana, to insulate its North American production from geopolitical shocks.
- The US holds a significant long-term geographical advantage with its large domestic sodium reserves, which account for 45% of the top five global reserves, but this is only valuable if a domestic manufacturing base can be successfully established.

Sodium-Ion Commercial Scale, GM Prototypes vs CATL 175 Wh/kg
Sodium-ion technology rapidly matured from lab-scale validation to commercial mass production between 2023 and 2026, but this progress was led entirely by Chinese firms, leaving Western counterparts like GM in a state of developmental catch-up.
- From 2021-2023, sodium-ion technology was largely at a Technology Readiness Level (TRL) of 5-6. During this time, CATL announced its first-generation cells with an energy density of 160 Wh/kg and laid out a roadmap for mass production.
- By 2026, Chinese manufacturers had achieved full commercial scale. CATL began mass production of sodium-ion batteries for EVs and energy storage with cell energy densities reaching 175 Wh/kg, making them competitive with LFP chemistry. Simultaneously, cell costs fell by 24% year-over-year to approximately $57/k Wh.
- In stark contrast, GM‘s sodium-ion efforts in 2026 remain in the prototype stage. Its initial application is targeted at grid storage, indicating the company is several years behind its Chinese competitors in bringing a commercially viable, automotive-grade product to market.

Table: SWOT Analysis for GM’s Alternative Battery Strategy
| SWOT Category | 2021 – 2024 | 2025 – 2026 | What Changed / Validated |
|---|---|---|---|
| Strengths | Focus on a proven Li-ion platform (Ultium) with a clear domestic manufacturing roadmap (160 GWh target). | Strategy leverages abundant and low-cost raw materials (sodium, manganese), directly addressing the core cost and geopolitical risks of lithium and cobalt. The US also holds large sodium reserves. | The strategic rationale for non-lithium chemistries was validated. The focus shifted from optimizing Li-ion to de-risking the entire supply chain. |
| Weaknesses | No public commercial activity or partnerships in sodium-ion technology. Strategy was fully dependent on the Li-ion supply chain. | GM is in the prototype stage for Na-ion, while Chinese firms like CATL are in mass production. GM lacks the partnerships and scale needed to compete on cost or volume in the near term. | The technology gap widened significantly. What was a research topic became a mass-market reality for Chinese firms, leaving GM several years behind. |
| Opportunities | IRA incentives (e.g., 45 X tax credit) created a favorable environment for domesticating the battery supply chain. | Develop and scale LMR and Na-ion to create a truly resilient, non-Chinese supply chain for affordable EVs and grid storage, insulating production from geopolitical shocks. | The opportunity became more urgent and specific. It is no longer just about onshoring Li-ion but about leapfrogging to alternative chemistries to escape Chinese control. |
| Threats | Growing awareness of China’s dominance in Li-ion mineral processing (70-85% control of key components). | China’s first-mover advantage and scale in sodium-ion (370 GWh capacity, $20 B+ investment) creates a formidable barrier. Chinese Na-ion cells at $57/k Wh set a difficult cost target to match. | The threat fully materialized. China not only controls the current Li-ion supply chain but has also moved to dominate the most viable alternative, creating a new and even more entrenched dependency. |
GM 2028 LMR Commercialization and Na-ion Pilots
For GM to successfully de-risk its supply chain, it must translate its LMR and sodium-ion R&D into commercial products by 2028; failure to achieve this will cede the entire low-cost battery segment to Chinese manufacturers indefinitely.
- If this happens: GM announces a firm timeline and capital investment for a giga-scale LMR battery plant in the US before 2027. This would be the strongest signal that it intends to compete directly with Chinese LFP batteries in the mass market.
- Watch this: The deployment of GM‘s first grid-scale energy storage projects using its proprietary sodium-ion technology. The performance and cost data from these pilots will be the first real-world validation of its technology against established Chinese products.
- These could be happening: GM forms a joint venture with a non-Chinese chemical or mining company to create a vertically integrated sodium-ion supply chain. Such a move would signal a serious acceleration of its strategy, mimicking the ecosystem-building approach of its rivals like BYD.
