MG electric vehicles to be fitted with SolidCore batteries
Electric vehicles are rapidly evolving. This was reported by Zamin.uz.
Terms in the field of battery technologies are also becoming more complex. Moving beyond traditional liquid electrolyte batteries, an era of transition to safer and more efficient solid-state technologies is beginning.
These changes will not only increase driving range but also significantly reduce charging time. This is reported by Autocar.co.uk.
The MG brand has announced the start of mass production of its semi-solid-state batteries, named SolidCore. According to the company, this technology will appear in MG electric vehicles in the European market by the end of this year.
SolidCore cells contain both solid and liquid electrolytes, but the liquid portion makes up only up to five percent. This allows for better performance in cold weather and faster charging compared to conventional batteries.
Other manufacturers on the market mostly use electrolyte gels for semi-solid-state technologies, but MG's approach is somewhat different. At the same time, Renault's Ampere division is accelerating the development of lithium-metal-based batteries in collaboration with Basquevolt.
This technology is based on a special polymer electrolyte that enables the use of lithium-metal instead of conventional graphite anodes. Using lithium-metal anodes sharply increases the battery's energy density.
However, this technology has posed challenges for engineers over a long period. One of the main problems is the formation of dendrites.
These can grow through the electrolyte and reach the cathode, potentially causing a short circuit. Additionally, changes in lithium-metal volume during charging can threaten the integrity of the battery pack.
The Ampere and Basquevolt collaboration has already shown positive results. Their technology not only achieves high energy density but also helps reduce the cost of manufacturing battery packs.
If safe use of lithium-metal anodes is achieved, charging times for electric vehicles could nearly match the refueling time of internal combustion engine vehicles. Currently, semi-solid-state batteries are considered a well-developed technology, and MG is taking a pioneering step in this area.
However, industry giants are also actively working on fully solid-state batteries. For example, Nissan has promised to unveil its first electric vehicle equipped with such technology by 2028.
Taking into account that electric vehicles are becoming widespread in the Uzbek market as well, these new technologies will also be of significant importance for local consumers in the future.
