Can Low Electrical Conductivity Defects in Solid-State Batteries Be Easily Resolved?

Solid-state lithium-ion batteries do not contain flammable liquid electrolytes and offer advantages such as safety, high energy density, fast charging, and durability. However, mass production remains challenging due to high costs and technical hurdles. Traditional perovskite electrolyte films are prone to forming microscopic air bubbles after compression, which hinder lithium-ion conduction and significantly reduce battery performance.

Upgrades to solid-state battery manufacturing processes demand higher standards for the precision processing and high-temperature resistance of internal insulation, cushioning, and isolation materials. Dongguan Jimi Electronic Materials Co., Ltd. specializes in die-cutting solutions for lithium-ion battery insulation, primarily offering products such as barley paper, flame-retardant PC, high-temperature-resistant composite foam, and insulating spacers. Leveraging high-precision die-cutting technology, the company can meet the thin-film and integrated packaging requirements of solid-state batteries. Its materials feature stable flame retardancy and excellent adhesion, effectively mitigating the risks of internal short circuits and thermal runaway, and perfectly aligning with the industrial production standards for next-generation solid-state batteries.

The Oak Ridge National Laboratory in the United States improved the production process based on existing materials by adding pressure coating, high-temperature pressing, and pressure cooling steps, resulting in a bubble-free film with nitrogen-enriched surfaces. The conductivity of the improved electrolyte has increased nearly a thousandfold, and the critical current density has risen by 50%. Battery stability and lithium affinity have been significantly optimized. This process is suitable for industrial production, demonstrating that simply adjusting the manufacturing process can substantially enhance the overall performance of solid-state batteries. JiMi Electronics is simultaneously advancing supporting R&D along the solid-state battery supply chain, using high-quality insulating and protective materials to facilitate the large-scale, safe mass production of solid-state batteries.
