New Energy Chemicals
The fastest-growing and most cyclically violent of the four sectors. It runs on two chains: batteries — cathode, anode, electrolyte, separator and copper foil — and solar — polysilicon, silver paste and encapsulation materials.

Sector overview
What makes this sector unusual is that high growth and overcapacity coexist. On demand, global lithium battery materials reached roughly USD 128 billion in 2025, up 22.5%, with energy-storage shipments growing 57%. On supply, capacity utilisation at the top ten cathode makers fell to 68% and leading gross margins slipped from 21% to 17.5%.
Technology transitions are the main mechanism redistributing profit. Silicon-based anode penetration jumped from 8% in 2024 to 14.5% in 2025, LiFSI loading in electrolytes is rising fast, and coated separator penetration moved from 51% to 67%. Whoever locks in the process and customer qualification for the next chemistry sets the price.
Geographic structure is being rewritten by policy. China still holds around 68%–73% of global battery materials capacity, but the EU Battery Regulation's carbon-footprint and recycling rules plus IRA localisation requirements are driving capacity into Southeast Asia and the West. Supply chains are shifting from efficiency-optimal to compliance-reachable.

Segments and key indicators
Solar materials use a separate basis and must not be added to battery materials.
| Segment | Main product families | Key variable |
|---|---|---|
| Cathode materials | LFP, NCM / NCA, LCO, LMO | Storage lifts LFP back to 32%; high-nickel 9-series shipments +35% |
| Anode materials | Synthetic graphite, natural graphite, silicon / silicon-carbon composites | Silicon penetration 8% → 14.5%; synthetic graphite still ~70% |
| Electrolytes & additives | LiPF₆, LiFSI, film-forming and flame-retardant additives, DMC / EMC solvents | LiFSI loading rising fast; LiPF₆ price swings dominate margin |
| Separator materials | Wet / dry base film, ceramic and PVDF / aramid coating | Wet process 73%; coating penetration 51% → 67% |
| Copper foil & current collectors | Sub-6μm battery foil, composite current collectors | Sub-6μm share around 48% |
| Solar encapsulation materials | EVA film, POE film, backsheet, silver paste | EVA ~1.76 Mt in 2025E; POE ~0.5 Mt (CAGR ≈ 35%) |
Main participants
Chinese firms dominate midstream scale and integration; Japanese and Korean players retain technology leadership in high-end separators, binders and NCM.
| Company | Positioning |
|---|---|
| 天赐材料 | Integrated electrolyte; leading LiFSI synthesis margin |
| 多氟多 | LiPF₆ and electrolyte additives |
| 华友钴业 / 中伟股份 | Integrated cathode precursors, 28%–32% gross margin |
| 恩捷股份 | Leading global wet-process separator share |
| 璞泰来 | Anode materials and coated separators |
| LG Chem / 住友化学 / 旭化成 | High-end NCM, separators and binders |
Key trends
These judgements are compiled from public sources and indicate direction rather than precise forecasts.
Storage cell shipments grew 57% in 2025, well above power batteries, pulling LFP cathode and electrolyte demand. Storage economics reward cycle life and levelised cost, favouring different chemistries than passenger EVs.
Top-ten cathode utilisation fell to 68% and leading margins from 21% to 17.5%. Smaller capacity is exiting while leaders build abroad — over 900 kt planned in Europe, with roughly 30% schedule slippage.
Solid electrolyte patent filings passed 8,500 in 2025, up 42%. Sulphide and oxide routes have not converged; near-term revenue impact is limited but the patents gate the next cycle.
The EU Battery Regulation targets a 30%+ carbon-footprint cut by 2030 with recycling efficiency targets; the IRA sets 2027 component localisation ratios. Southeast Asian capacity under construction grew 40% in 2025 — localisation moved from option to requirement.
