Core Technology Premium (Dominance of High-Density Products)
-
Surge in Cost of 4th-Gen High-Density Materials
Fourth-generation LFP with a compaction density ≥2.6g/cm³ significantly enhances energy density (enabling fast charging and extended range), making it critical for next-gen EV batteries. However, technological barriers elevate processing fees by US$280-420/ton compared to standard products (Source 1,5). Leading batteries like CATL's Shenxing PLUS and BYD's Blade Battery rely on this high-end material (Source 2,6).
-
Increased Process Complexity
Achieving high compaction density requires optimized particle grading, secondary sintering processes, and electrolyte formulations. This raises energy consumption during production and challenges yield control, directly increasing manufacturing costs (Source 3,4).
Severe Supply-Demand Imbalance
-
Structural Shortage of High-End Capacity
While top battery makers (e.g., CATL, BYD) rapidly shifted to 4th-gen high-density LFP in 2025, mainstream suppliers remain focused on 3rd-gen products (compaction density 2.5-2.6g/cm³). Lagging new production line deployments have created a supply gap (Source 5,8). Example: Jiangsu LORD's ¥7B order from CATL faces fulfillment challenges despite full-capacity production (Source 7,8).

Raw Material Cost Transmission
-
Lithium Carbonate Volatility: Despite falling from 2023’s peak of ¥600,000/ton, it still constitutes ~40% of battery cost in 2025, with price fluctuations directly impacting end-product pricing (Source 1,9).
-
Phosphate Shortage: Accounts for 40% of cathode material cost. Concentrated phosphate rock resources (dominated by Yunnan Yuntianhua, Xingfa Group) coupled with environmental production restrictions drive up raw material prices (Source 4,10).

Illustration: A ¥1,500/ton LFP price increase raises battery cost by only ~¥105 for a 70kWh pack. However, high-density variants command higher premiums due to performance advantages (Source 1).
Market Applications Driving Upgrades
-
Automaker Tech Race: To balance range and cost, automakers prioritize high-density LFP (e.g., 4C fast-charging models), with premium EVs absorbing costs through performance-based pricing (Source 2,6).
-
Capacity Competition: Energy storage (S5 models) and EV batteries (255/265 models) experience simultaneous demand surges, worsening supply constraints (Source 4).
-
Emerging Sectors: Low-altitude economy applications (e.g., eVTOL aircraft) further divert high-energy-density battery capacity (Source 12).
Future Outlook
Current high prices stem from structural shortages of premium products. As industry leaders like CATL and BYD commission new production lines (e.g., Jiangxi Shenghe's 160k-ton capacity) (Source 11) and lithium carbonate prices trend downward (Source 9), 4th-gen high-density LFP costs may stabilize post-2026. Nevertheless, performance premiums from ongoing tech innovations will persist long-term.
