Solid-state electrolyte for pressure-free secondary batteries using sulfur-ester bonded organic polymers

This technology relates to a solid-state electrolyte for pressure-free secondary batteries composed of an organic polymer with a specific chemical formula containing sulfur and ester/thioester bonds.

Conventional solid-state electrolytes require high pressure to ensure interfacial contact with electrodes, and they struggle to maintain ion conductivity and interfacial stability under pressure-free conditions.

By utilizing sulfur-ester bonded organic polymers, this technology can be applied to pressure-free secondary batteries, ensuring effective interfacial contact and ion conductivity without the need for external pressure.
