Chinese Scientists Develop Semi-Solid EV Battery with Over 1,000 km Range
Researchers in China have developed a new semi-solid-state battery for electric vehicles that could significantly extend driving range. The new technology reportedly enables more than 1,000 km of range on a single charge, marking a major advancement in EV battery development.
The battery combines solid and liquid electrolytes along with a lithium-manganese cathode, increasing its energy density by about 30% compared with conventional lithium-ion batteries.
Hybrid Electrolyte Design Improves Efficiency and Safety
The battery uses an advanced hybrid structure featuring a super-wetting composite electrolyte. This electrolyte is capable of fully penetrating the microscopic pores within the battery materials.
This design offers several advantages:
-
Improved ionic conductivity
-
Higher energy efficiency
-
Better thermal stability and safety
In addition, engineers used a lithium anode, which simplifies manufacturing while also improving the overall lifespan of the battery.
High Energy Density and Large Battery Capacity
According to the research team, the new battery delivers impressive energy density figures.
| Battery Specification | Details |
|---|---|
| Pack Energy Density | 288 Wh/kg (including cooling and wiring) |
| Cell Energy Density | 500 Wh/kg |
| Prototype Battery Capacity | 142 kWh |
| Estimated Range | Over 1,000 km |
With a 142 kWh battery pack, electric vehicles equipped with this technology could travel more than 1,000 kilometers on a single charge, significantly exceeding the range of most current EVs.
Future Versions Could Reach 1,600 km Range
Scientists say the technology still has room for improvement. Future versions of the battery could reach:
| Future Target | Expected Performance |
|---|---|
| Energy Density | Over 340 Wh/kg |
| Battery Capacity | Up to 200 kWh |
| Estimated Range | Up to 1,600 km |
However, researchers note that real-world driving conditions, including weather, terrain, and driving style, will likely reduce the actual range.
A Potential Breakthrough for Electric Vehicles
Despite these limitations, the development represents an important step forward for electric vehicle battery technology. Increasing range and energy density is one of the biggest challenges in the EV industry, and semi-solid-state batteries could provide a balance between safety, performance, and production feasibility.
The new semi-solid battery developed by scientists in China could mark a major breakthrough in EV technology. With the potential to deliver over 1,000 km of driving range today and up to 1,600 km in the future, this innovation may significantly accelerate the adoption of electric vehicles worldwide.
