Volatility in prices of key coating raw materials such as PVDF and battery-grade alumina increases production costs
One of the major restraints affecting the growth of the Japan battery coating market is the volatility in prices of essential coating raw materials, particularly polyvinylidene fluoride (PVDF) and battery-grade alumina. In May 2026, according to the article by Sohu, the average prices for mainstream Kureha Japan PVDF prices for industrial grade are USD 8,630-10,267 (RMB 58,000-69,000) per ton, whereas prices for lithium-battery-grade materials are estimated at USD 17,112-27,677 (RMB 115,000-186,000) per ton, showing how expensive it is to produce battery coatings of high quality. Moreover, it is stated that some PVDF grades manufactured by Kureha Company cost about USD 26.5 (RMB 178/kg) (W#850), USD 23 (RMB 155/kg) (W#9300), and USD 24.5 (RMB 165/kg) (KF1300), whereas spot prices from Shanghai Fluorine New Materials could be 5%-15% cheaper.
Additionally, variations in prices of PVDF raw materials may further add to the pressure on the cost of production. According to Sohu, R142b constituted more than 90 percent of the cost of Wu Yu PVDF, which was estimated to cost about USD 26,784 (RMB 180,000) per ton in August 2025, while high demand for lithium-ion batteries and photovoltaic applications had contributed to its shortage. The report also shows that domestically manufactured PVDF had been priced at about USD 8,184-10,267 (RMB 55,000-69,000) per ton, compared to USD 17,112-27,677 (RMB 115,000-186,000) per ton for imported PVDF due to its relatively low impurity content and consistent batch quality for lithium-ion battery applications. Therefore, fluctuations in PVDF raw material price and grade-based prices will result in increased costs of procurement of coating materials, reduced margins, and increased difficulty in maintaining stable pricing for Japanese battery-coating manufacturers.
