Facing the hidden danger of power battery puncture, SUMINO MDO stretching device builds a safety defense line with nanoscale pore regulation technology——

Hardcore Technical Barriers

Synchronous double stretching: longitudinal reinforcement of molecular chains + transverse micropore expansion, achieving a breakthrough in the "high strength - high porosity" paradox;

Plasma interface activation: compatibility of inorganic fillers is doubled, and the closed - cell temperature is broken through;

Self - healing microcracks: elastomer molecular bridging technology, extending the cycle life.

Overcoming Safety Pain Points

Out - of - control thermal shrinkage: gradient heat setting technology, leading in dimensional stability in the industry;

Uneven pores: ultrasonic amplitude regulates micropore distribution, stabilizing ion conductivity;

Metal impurities: production in a fully enclosed inert environment, eliminating the risk of micro - short circuits.

New Energy Value

Puncture strength exceeds industry standards;

Fast charging cycle life is doubled;

Mass production of thin base films for solid - state batteries.
