This report critically examines the implications of recent tariff adjustments and international strategic countermeasures on Wet Separators for Lithium-ion Batteries competitive dynamics, regional economic interdependencies, and supply chain reconfigurations.
Separator usually refers to a porous membrane material located between the positive and negative electrodes of a battery. Its main function is to prevent the positive and negative electrodes from directly contacting each other and causing a short circuit, while allowing electrolyte ions to pass through to maintain the battery's charge and discharge process. The wet process is also known as the thermally induced phase separation method. The wet process adopts the principle of thermally induced phase separation. The plasticizer is mixed with the polyolefin resin. Solid-liquid phase/liquid-liquid phase separation occurs during the cooling of the molten mixture. The membrane is pressed and heated to a temperature close to the melting point. It is then stretched to align the molecular chains. The film is kept warm and a volatile solvent is used to extract the plasticizer from the film to produce a diaphragm.
As a core component of lithium-ion batteries, wet-process diaphragms are mainly driven by the following market factors:
Technology iteration drives performance breakthroughs
Wet-process diaphragms use thermally induced phase separation technology to achieve precise control of microporous structure (higher porosity and more uniform pore size distribution), significantly improving battery energy density (suitable for high-end scenarios such as ternary lithium batteries) and cycle life. Compared with dry-process diaphragms, wet-process products have better electrolyte wettability and thermal stability (thermal shutdown temperature reaches 180掳C), effectively responding to the safety challenges of high-energy density batteries, and technological generational advantages directly promote penetration in the mid-to-high-end market.
Policies and industrial chain synergy strengthen
Global new energy policies (such as China's dual credits and EU carbon neutrality) force battery performance upgrades, and wet-process diaphragms as key materials benefit from subsidy guidance (such as priority support for high-energy density batteries). At the same time, the localization of upstream materials (such as breakthroughs in polyethylene and ceramic coating technology) reduces costs, and the evolution of downstream solid-state battery technology generates demand for new diaphragms. The industrial chain synergizes to accelerate the iteration of wet-process diaphragm technology.
Demand upgrade opens up incremental space
High-end electric vehicles: the penetration rate of ternary lithium batteries has increased, wet-process diaphragms are adapted to the needs of high-nickel systems, and the value of each vehicle has increased accordingly.
Diversification of energy storage scenarios: household energy storage and grid-level energy storage have upgraded requirements for cycle life and safety, and wet-process diaphragms have gradually replaced dry-process products with their performance advantages.
Iteration of consumer electronics: 5G devices and wearable devices have a demand for thinner and lighter batteries, which drives wet-process diaphragms to develop in a thinner direction.
The generational gap in technology builds a moat, the resonance of policies and the industrial chain provides thrust, and the demand upgrade opens the ceiling. The three jointly drive the wet-process diaphragm market from high-end consumer batteries to the full range of power batteries.
