BORDENTOWN, N.J.– (BUSINESS WIRE)– Algemeen wordt aangenomen dat vaste polymeerelektrolyten bij kamertemperatuur een slechte ionische geleidbaarheid hebben. Nuvvon heeft dit idee op zijn kop gezet. Door derden geverifieerde gegevens van hun unieke vaste polymeerelektrolyten worden gepresenteerd om dit te bewijzen.

Solid-state batterijbedrijven die oxide- en sulfideproducten ontwikkelen, suggereren dat vaste polymeerelektrolyten moeite hebben met het bereiken van de noodzakelijke ionische geleidbaarheid bij kamertemperatuur. Een mogelijke oplossing is om de bedrijfstemperatuur te verhogen, wat niet optimaal is omdat er externe verwarming voor nodig is. Een andere is de toevoeging van vloeibare weekmakers, zoals ionische vloeistoffen, om de geleidbaarheid te verhogen. Maar de hoeveelheid vloeibare weekmaker die nodig is voor gebruik bij kamertemperatuur resulteert in slechte mechanische eigenschappen en ondermaatse thermische veroudering.

Nuvvon Abolishes the Myth that Solid Polymer Electrolytes Have Poor Ionic Conductivity at Room Temperature

BORDENTOWN, N.J.–(BUSINESS WIRE)– It is generally assumed that solid polymer electrolytes have poor ionic conductivity at room temperature. Nuvvon has turned this notion on its head. Third-party verified data of their unique solid polymer electrolytes is presented to prove it.

Solid-state battery companies developing oxide and sulfide products suggest that solid polymer electrolytes have struggled with achieving the necessary ionic conductivity at room temperature. One attempted workaround is to increase the operating temperature, which is sub-optimal as it requires external heating. Another is the addition of liquid plasticizers, such as ionic liquids, to increase conductivity. But the amount of liquid plasticizer required for room temperature operation results in poor mechanical properties and subpar thermal aging.

Nuvvon has developed solid polymer electrolytes that overcome this problem. Nuvvon’s polymer electrolytes are completely dry and do not require the addition of ceramic nanomaterials. Nuvvon’s solid polymer electrolytes can also withstand high temperatures (>100^oC) without mechanical degradation and demonstrate high ionic conductivity across a wide temperature range (2.2*10-4 S/cm at 0 ^oC, 4.6*10-3 S/cm at 25^oC, 6.6*10-3 S/cm at 80 ^oC).

Nuvvon’s breakthrough in solid polymer electrolytes enables, for the first time, completely solid-state pouch cells that operate across a wide temperature range without external systems for cooling, heating, or pressure.
