GM-LG Ultium retool Tennessee for manganese-rich cells

The GM-LG Ultium joint venture is converting its Spring Hill, Tennessee plant to produce manganese-rich cathode cells, cutting cobalt dependence and lowering costs.

  • Spring Hill facility converting to LMFP/manganese-rich chemistry
  • Cobalt content reduced by over 70% versus prior NMC cells
  • First cells from the retooled line expected Q1 2027
Why it mattersCutting cobalt is the battery industry's most important supply-chain move of the decade — Tennessee shows it's becoming mainstream, not experimental.

Adani Green's Khavda BESS expands to 6.63 GWh

Adani Green Energy has expanded its Khavda battery energy storage system in Gujarat to 6.63 GWh, making it one of the largest operational BESS installations in the world.

  • Total capacity now 6.63 GWh at the Khavda complex
  • Paired with 30 GW of renewable generation capacity at the site
  • Supports India's 500 GW non-fossil target by 2030
Why it mattersKhavda's scale shows that utility BESS is no longer a pilot category — gigawatt-hour storage is now deployed infrastructure in emerging markets.

Samsung SDI launches AI data-centre LFP cell format

Samsung SDI debuted a new cylindrical LFP battery format at the Singapore expo, targeting AI data-centre backup power where cycle life and fire safety matter most.

  • New cylindrical LFP cell optimised for UPS and rack-scale backup
  • 2,000+ cycle life at 80% capacity retention
  • First shipments to hyperscaler customers in Q2 2027
Why it mattersLFP's safety profile is increasingly the deciding factor as hyperscalers race to build data centres fast — Samsung is betting the chemistry wins on compliance grounds.

US battery storage heading for 24.3 GW annual record in 2026

The US is on track to install 24.3 GW of battery storage in 2026, shattering the previous annual record and cementing storage as the fastest-growing segment of the grid.

  • 24.3 GW projected for 2026, up 40% year-on-year
  • Texas and California account for over half of new capacity
  • IRA tax credits driving project economics across all regions
Why it mattersAn annual record by this margin makes battery storage an unstoppable grid fixture — utilities that have not planned for it are already behind.

Stryten acquires Trojan Battery, builds 18-facility US network

Stryten Energy completed its acquisition of Trojan Battery, giving it an 18-facility US manufacturing network spanning lead-acid, lithium, and flow battery chemistries.

  • Stryten now operates 18 US manufacturing and R&D facilities
  • Trojan's deep-cycle lead-acid expertise adds industrial storage
  • Combined entity targets $2B revenue in 2027
Why it mattersConsolidation across battery chemistries signals US manufacturers are betting on a multi-chemistry future rather than a single-winner outcome.
