Energy storage demand has become the core incremental growth driver of the global battery value chain

Overview

This is a global energy storage and battery weekly report, mainly covering increasing EV penetration, expansion of energy storage system demand, U.S. domestic battery supply-chain buildout, Korean battery makers' capacity reallocation, key material orders, and solid-state battery progress. The core takeaway is that although EV demand faces policy and cycle headwinds, energy storage—especially U.S. data-center and grid storage demand—is becoming an important support for the battery value chain.

Core views

The report presents a constructive view on storage demand. The substitution effect of EVs in global energy consumption continues to expand, as EVs can reduce oil import spending in China, Europe, and India. At the same time, U.S. data center electricity use and AI infrastructure are driving rapid ESS demand growth, prompting companies such as LG Energy Solution, Samsung SDI, and SK On to shift some EV-focused production lines toward storage. CATL is being favored by the market due to storage growth and strong profitability, while Korean cathode-material firms still face valuation, earnings, and demand-deceleration pressure.

Analysis framework

The report takes a news-flow and value-chain tracking approach, combining company announcements, media reports, BloombergNEF forecasts, order data, capacity plans, tax credit policy, and valuation tables to assess marginal shifts in EV, ESS, LFP, cylindrical batteries, solid-state batteries, and materials segments of the battery value chain.

Methodology notes

• Supply chain trackingBattery and energy-storage weekly event-driven analysis

  Identify marginal changes in the value chain through order flow, capacity, policy, demand forecasts, and stock performance.

  The report is not a deep dive on a single company, but places EV, ESS, materials, and battery manufacturers’ news and valuation entries in one framework to judge demand migration and which companies are likely beneficiaries.

• Relative valuationComparing ratings, target prices, and P/E

  Use company ratings, target prices, current prices, relative performance, and expected P/E to evaluate stock risk and return.

  The table covers CATL, LG Chem, LG Energy Solution, Samsung SDI, Posco Future M, EcoPro BM, Sungrow, and Tianqi Lithium, but the report itself did not add any new single-company rating.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• CATL

  A global battery and storage leader; the table covers 300750.CH and 3750.HK.

  Strengths

  Strong storage growth, earnings support stock gains, and Hong Kong shares have become an important proxy for the energy storage theme.

  Weaknesses

  The H-share premium versus A-shares has risen to a high level, increasing valuation sensitivity.

  Comparison

  Compared with Korean battery makers, CATL has stronger scale and cost advantages in LFP and storage markets.

  Risks

  Valuation pullback, trade policy, overseas market access, and storage price competition.

• LG Energy Solution

  Korean battery maker supplying Megapack 3 cells to Tesla and advancing Arizona 46-series battery production.

  Strengths

  Secured large Tesla orders, has domestic U.S. capacity, and maintains a pipeline of cylindrical-cell orders from multiple customers.

  Weaknesses

  Slowing EV demand is forcing part of capacity to move toward ESS, and profitability remains affected by utilization and subsidy reliance.

  Comparison

  Like Samsung SDI and SK On, it is allocating more of its U.S. battery capacity to ESS.

  Risks

  Policy shifts in the U.S., tariffs, customer concentration, ramp-up of production lines, and ESS pricing competition.

• Samsung SDI

  Korean battery maker shifting into the U.S. ESS market through StarPlus Energy JV.

  Strengths

  New ESS orders of about US$1.1 billion and plans to supply NCA and LFP batteries; target is mass production of solid-state batteries in the second half of 2027.

  Weaknesses

  EV deceleration is requiring JV line reallocation, and it may need capital from Samsung Display stake disposal.

  Comparison

  Like LG Energy Solution, Samsung SDI is also tilting Stellantis-related joint-venture capacity toward ESS.

  Risks

  Capital expenditure pressure, solid-state commercialization uncertainty, ESS order execution, and pace of quarterly profit recovery.

• SK On

  Korean battery maker planning to enter U.S. ESS and data-center storage supply.

  Strengths

  Targets at least 10 GWh of ESS contracts in the U.S. this year and differentiates through safety-testing technology.

  Weaknesses

  Recorded a KRW 3.7 trillion impairment after ending the Ford JV, and faces significant pressure to reallocate EV capacity.

  Comparison

  Compared with LG and Samsung SDI, SK On’s ESS transition has a stronger element of restoring utilization and digesting EV setbacks.

  Risks

  Customer acquisition, LFP cost competition, U.S. plant conversion efficiency, and technology commercialization validation.

• Posco Future M

  Battery materials company securing long-term synthetic graphite orders.

  Strengths

  A KRW 10.149 trillion synthetic graphite contract complements prior natural graphite agreements and supports new capacity buildout in Vietnam.

  Weaknesses

  Anode and cathode material cycles still depend on EV demand and customer production recovery.

  Comparison

  It has an additional anode-material order thread compared with pure cathode-material peers, but remains under price and utilization pressure in the battery materials chain.

  Risks

  New plant ramp-up, order execution, material price volatility, and customer demand below expectations.

• Eve Energy

  Company related to solid-state battery technology progress.

  Strengths

  Released solid-state battery products for EVs, consumer electronics, humanoid robots, drones, and AI devices.

  Weaknesses

  The new Chengdu solid-state battery plant has annual output of about 100 MWh, enough for roughly 1,000 100-kWh EVs, still far from large-scale automotive mass production.

  Comparison

  Its technology demonstration is more significant than its near-term production contribution.

  Risks

  Solid-state battery yield, cost, pressure management, customer validation, and uncertainty around scaling into mass production.

Impact & implications

The implication for the industry is that growth drivers for battery companies are shifting from single-thread EV penetration toward a dual EV-plus-ESS model. In particular, U.S. data-center and grid storage demand may cushion the impact of slower EV demand on Korean battery makers. For investors, companies with LFP capability, ESS customers, domestic U.S. capacity, and cost advantages are more likely to benefit, while companies dependent on EV growth and cathode-material earnings recovery face higher risk.

Risks

• U.S. EV demand continues to slow as policy winds and tax-credit changes turn less favorable.
• ESS demand is highly sensitive to data centers, grid investment, tax credits, and the interest-rate environment.
• Shifting battery plants from EV to ESS can create uncertainty around line conversion, certification, customer mix, and margins.
• Intensifying competition in LFP and storage systems may compress prices and profits.
• Solid-state batteries remain in early production ramp stages, with limited short-term commercial contribution.
• After strong appreciation in leaders such as CATL, valuation premiums have widened and pullback risk is rising.
• Trade tariffs, supply-chain localization, and U.S.-China geopolitical policy could affect cross-border battery supply.
