Although solid-state battery technology still needs to improve durability and performance, high production cost is still the main obstacle. However, this could soon change thanks to a new battery design developed by scientists at the University of Science and Technology of China (USTC). a product that is reduced to only 10% of the original.

China has developed batteries for electric vehicles with cheap electrolyte
Although solid-state battery technology still needs to improve durability and performance, high production cost is still the main obstacle. However, this could soon change thanks to a new battery design developed by scientists from the University of Science and Technology of China (USTC).
The new solid state battery design could perform similarly to next generation battery technologies, but at a lower production cost of only 10% of the original version. This major advance makes solid state batteries much more affordable.
A key component of this innovation is a new solid electrolyte that eliminates the need for expensive lithium sulfide (Li2S). This can significantly reduce production costs and make these batteries more affordable.
According to Chinese media, this development could move China to the front in the race for battery market leadership. Many believe that solid-state batteries are the future of energy technology, and China could take a leading role in this field.
Solid-state batteries differ from traditional batteries in that they use solid electrolytes instead of liquid or gel electrolytes, which transport ions between the electrodes. These batteries promise to solve the capacity and safety issues of traditional lithium-ion batteries. Sulfides and oxides can be used as cathodes to increase energy density, with sulfides considered the most promising option.
However, the cost of sulfide electrolytes is very high – more than $195 per kilogram. For mass adoption, this cost should be less than $50 per kilogram. The main reason for the high cost is the complex synthesis process, which depends on expensive Li2S.
A team led by Ma Cheng from USTC has developed a new material called LPSO that does not require lithium sulfide. This electrolyte is synthesized from two cheap compounds, reducing the cost of the material to $14.42 per kilogram, less than 8% of the cost of other solid electrolytes.
Despite its low cost, LPSO retains the main advantages of the best sulfide electrolytes, including anode consistency and performance consistency. It also pairs well with high energy density anodes such as lithium and silicon. The battery, made using LPSO and lithium metal, showed more than 4,200 hours of continuous cycling at room temperature.
