- Peak Energy plans to build the first US commercial factory in California for grid-scale sodium-ion battery systems, targeting 4 GWh annual capacity and starting customer deliveries in March 2027.
- LGES, Samsung SDI, CATL and others continue to expand around ESS, backup power for AI data centers, commercial-vehicle fast charging, and next-generation batteries.
- Yunnan has released a list of 1.9 GW/7.6 GWh shared storage projects, all using sodium-ion and all-vanadium flow technologies with non-lithium chemistries, showing rising interest in long-duration storage and alternative technology paths.
Report interpretation
Overview
Bernstein's current "Global Energy Storage: Battery Weekly" focuses on the latest developments in the global battery and storage industry, covering regions including North America, Asia, and Europe. Topics include US critical mineral procurement, sodium-ion and solid-state battery projects, expansion of ESS capacity, battery demand from AI data centers, competition dynamics in the European new-energy-vehicle market, and progress in battery-material substitution and recycling technologies.
Core views
The report's core industry signal is that storage demand remains a major incremental driver for the battery sector, while AI data centers are becoming a new high-power backup power and ESS application. Sodium-ion, solid-state batteries, and all-vanadium flow batteries are shifting from R&D toward demonstration and early commercialization. China, South Korea, and U.S. companies are increasing investment around supply-chain security, local manufacturing, and new chemistries. At the same time, differentiated EV demand, subsidy and tax-phase-downs, raw-material price volatility, and mass-production difficulty of new technologies remain key constraints.
Analysis framework
The report combines weekly news roundup, regional event synthesis, value-chain node tracking, and company valuation table updates. The main text organizes key events by Americas, Asia, Europe, and other regions, and uses price performance, valuation, ratings, and target-price tables to show market performance of major battery, lithium, cathode, anode, and separator companies.
Methodology notes
Identify marginal changes in supply and demand, technology, and policy in the battery industry through high-frequency news.
The report places corporate capacity expansions, government procurement, technology milestones, regional policies, and capex events in a single framework to help gauge near-term catalysts and the medium- to long-term direction for the storage and battery value chain.
Covers upstream lithium and graphite, midstream materials and cells, and downstream EV, ESS, and data center applications.
The report tracks not only cell makers, but also includes lithium miners, cathode, anode, separators, recycling materials, and end-use applications to observe how technology-route changes affect each stage of the chain.
Asset mapping & comparison
Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).
- CATLCore battery leader and beneficiary tied to ESS, commercial-vehicle fast charging, and alternative graphite-related materials
- Strengths
- It launched an 8C lightweight commercial-vehicle fast-charging battery and participates in sustainable graphite initiatives, demonstrating extension capability across both product and materials segments.
- Weaknesses
- Its global expansion and valuation resilience are exposed to policy, regional competition, and raw-material price dynamics.
- Comparison
- Compared with Korean battery makers, CATL is more prominent in Chinese supply-chain integration and ESS scaling.
- Risks
- Overseas regulation, trade barriers, chemistry-transition risk, and price competition.
- LG Energy SolutionCell maker tied to the Tesla supply chain and North American ESS expansion
- Strengths
- Its Nanjing plant expansion serves Tesla, while the Spring Hill plant is shifting to LFP ESS and targeting over 50 GWh of annual North American ESS capacity.
- Weaknesses
- Fluctuations in EV demand could affect utilization rates on certain production lines.
- Comparison
- Compared with Samsung SDI, LGES benefits more directly from Tesla cylindrical cells and the North American ESS manufacturing footprint.

- Customer concentration, execution of capacity conversion, North American policy, and cost pressure.
- Samsung SDIName linked to AI data-center backup power and next-generation battery investments
- Strengths
- Supplies AI data-center BBU cylindrical cells to Simplo and plans long-term investment in full-solid-state, LFP ESS, and sodium-ion batteries.
- Weaknesses
- The return period for large-scale capex is relatively long.
- Comparison
- Compared with LGES, Samsung SDI is more prominently positioned on high-nickel cylindrical cells and next-generation technology investment narratives.
