A Revolution in the World of Electric Vehicles with a Semi-Solid Battery
Introduction
Amid the global race to develop more efficient and environmentally friendly transportation, MG has taken a pioneering step by introducing the world's first production electric vehicle equipped with a semi-solid battery. This event was not just a simple technical update; it represented a qualitative leap that heralds a different future for electric vehicles. Are we witnessing the beginning of the end of traditional batteries?
1. What is a semi-solid battery?
A semi-solid battery is a new generation of energy storage technology that combines the properties of solid and liquid batteries. It is primarily composed of semi-solid electrolytes containing a small percentage of liquid (less than 5%), which enhances its safety and increases its operational efficiency, especially in harsh weather conditions.
The most prominent advantages of this type of battery are:
Higher resistance to high and low temperatures.
Reduced risk of explosion or ignition.
Faster charging capability.
Longer service life.
2. Why MG4 specifically?
MG, owned by the Chinese SAIC Group, announced the launch of the new MG4 model with a modern design, leading technologies, and the option of a semi-solid battery. The car targets the mid-range segment with prices starting at just around $10,000, making it accessible to a wide range of users around the world.
Among the MG4's most notable features are:
Powerful performance with an efficient electric motor.
A driving range exceeding 500 kilometers on a single charge.
Supports rapid charging, reaching 80% in less than 30 minutes.
Smart interior design with driving assistance technologies.
3. Technical Benefits of Using Semi-Solid Batteries in the MG4
Integrating this technology into the MG4 was not arbitrary. Rather, it was based on a set of real-world benefits demonstrated during testing, including:
Tolerance to cold conditions: The battery maintains more than 75% of its capacity even in temperatures as low as -20 degrees Celsius.
Stable and Safe Performance: No fires or leaks were recorded during extensive testing, even after the battery was subjected to severe penetration tests.
Long life: The ability to retain more than 80% of the battery's capacity after 2,000 charging cycles.
Thermal efficiency: Better heat distribution, increasing engine efficiency and reducing cooling energy consumption.
4. New MG4 Launch Timeline
June 2025: Completion of performance testing and final battery design.
July 2025: Beginning of industrial production of pilot models.
August 2025: Pre-orders open in China and Europe.
September 2025: Official pricing and features announced.
End of 2025: First batch delivered to customers and authorized distributors.
5. Comparing the MG4 with other electric cars

6. What impact will this technology have on the future of electric transportation?
The entry of semi-solid batteries into commercial production will certainly push the industry toward more advanced technologies and open the door to the adoption of full-solid batteries in the near future. It will also positively impact:
Production costs over time.
Confidence in safety and security.
Increasing the range of electric mobility in cold regions.
Supporting innovation among competing companies.
7. Challenges that may face the MG4 and semi-solid batteries
Despite the optimism, there are still some technical and logistical obstacles:
Higher manufacturing costs compared to conventional batteries.
Difficulty in immediately expanding global production.
Limited ultra-fast charging infrastructure in some countries.
However, these challenges are expected with any new technology and may be quickly overcome with widespread adoption by manufacturers.
Conclusion
The MG4, equipped with a semi-solid battery, represents a revolutionary step forward in the electric vehicle industry. It's not just an upgrade to the battery; it heralds the beginning of a new era. With its low price, high performance, and futuristic technology, it will undoubtedly shape the future of transportation in 2025 and beyond.
