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.
