This article analyzes the core differences and characteristics of three materials in the oxide electrolyte system: garnet-type (LLZO), perovskite-type (LLTO), and NASICON-type (LATP). It comprehensively dissects their respective advantages and challenges, covering aspects such as structure and ion migration mechanisms, chemical stability and interface compatibility, preparation difficulties and process control, as well as application scenarios and technological bottlenecks. Meanwhile, it provides a detailed introduction to the layout of various enterprises in the field of oxide electrolyte batteries, presenting readers with the current research and application status of oxide solid-state batteries, as well as future development trends.

This year, domestic and overseas lithium carbonate resource projects have been launched one after another, and smelting capacity has rapidly increased.

In 2025, Gotion High-tech's Jinshi all-solid-state battery will complete its pilot-scale production. Gotion High-tech will adopt a dual-line layout with 12 Gwh of quasi-solid-state batteries and 0.2 Gwh of all-solid-state batteries. By 2027, it aims to achieve mass production of 400 Wh/kg batteries, targeting a market worth hundreds of billions.

Ganfeng LiEnergy has achieved full coverage of the entire industry chain for solid-state batteries, with lithium sulfide mass production leading industry standards, and 500Wh/kg batteries set for commercial application in 2025.

Due to their high ionic conductivity and ease of processing, sulphide-based solid-state electrolytes have become the preferred choice for the industrialisation of all-solid-state batteries. However, breakthroughs are needed in terms of interface stability, cost reduction (e.g., replacing precious metals), and overcoming bottlenecks in large-scale production.
