Solid-State Batteries: Chinese Electrolyte Manufacturers on Fast-Track  
Commercialization – Jinlongyu Group and Liaoning Oxiranchem Inc. Leading  
the R&D on Solid-State Electrolytes  
According to MIR, the global vehicle electrification movement has seen remarkable  
progress during the first half of the year. While Japanese automakers such as Toyota,  
Nissan, and Honda remain in a "wait-and-see" state, Chinese counterparts have been  
swift in embracing EV technologies. Meanwhile, European, and American automakers are  
sparking a boom in electric vehicle factory construction.  
The shift towards global vehicle electrification is becoming more evident for the future.  
However, car buyers still have concerns about issues such as short range, slow charging  
speed, and safety. To address these market "pain points," power battery  
manufacturers are accelerating their investments and research in solid-state  
batteries.  
Recently, the momentum behind solid-state batteries has been increasing. Notably, with  
major news pieces like "Toyota's major breakthrough in solid-state battery technology and  
plans to launch electric vehicles equipped with advanced solid-state batteries by 2025"  
and "Solid-state batteries now officially incorporated into NIO vehicles, achieving mass  
production for the first time," the industry is witnessing remarkable progress. The  
commercialization process is accelerating, pointing towards a potential turning  
point in the industry.  
Compared to liquid-state batteries, solid-state batteries offer various performance  
advantages such as higher energy density, increased safety, longer cycle life, and better  
performance in low temperature.

Advantages  
Description  
Solid-state batteries use solid-state electrolytes instead of traditional liquid  
electrolytes, and solid-state electrolytes offer higher ionic conductivity, leading  
to increased battery energy density.

In comparison to liquid electrolytes, solid-state electrolytes can address safety

issues such as leakage and volatilization.  
Solid-state batteries eliminate the need for electrolytes and separators, enabling  
the stacking of multiple layers of positive electrode, solid-state electrolyte, and  
negative electrode materials. They are connected in series and then sealed  
through welding, effectively simplifying the packaging process, reducing the  
overall weight and volume of battery packs, and thereby enhancing the overall  
battery life.  
Lighter  
Solid-state electrolytes act as single-ion conductors, resulting in fewer side  
reactions and longer cycling life. As solid electrolytes lack fluidity, the recurring  
growth and dissolution of the solid electrolyte interface (SEI) film are avoided,  
contributing to stable cycling. Additionally, in full solid-state batteries, transition  
metals are less likely to dissolve, avoiding capacity degradation in positive  
electrodes caused by transition metal dissolution and the problem of transition  
metal deposition on the negative electrode side catalyzing SEI film  
decomposition.

The above table substantiates again that solid-state electrolytes are the  
fundamental materials of solid-state batteries, and the key distinction between  
solid-state batteries and mainstream traditional lithium-ion batteries lies in the electrolyte.  
Based on recent observation by MIR of several domestic electrolyte manufacturers  
(details in Table 2), the trend of the solid-state electrolyte industry is gradually emerging,  
with several Chinese companies already making inroads into this field. However, most of  
their products are still in the research and development stage and have not yet entered  
production. It is worth noting that Jiangsu Ruitai New Energy Materials Co., Ltd. and  
Liongo New Energy have shown more rapid progress compared to other companies in  
driving the industrialization of solid-state electrolytes.

The industrialization of solid-state electrolytes faces a significant challenge in striking the  
right balance between performance and cost. Currently, extensively researched oxide,  
sulfide, and chloride solid-state electrolytes struggle to meet the demands of high ionic  
conductivity, good deformability, and cost-effectiveness simultaneously. As a result, MIR  
believes that achieving maturity in solid-state electrolyte development will take time and  
considerable effort. In this competition for solid-state electrolytes, the manufacturers that  
excel must possess the technological prowess to drive their market-oriented development.
