Contemporary Amperex Technology Co, the world's largest EV battery maker, debuted on Tuesday what it claimed to be the world's first energy storage system with "ageless battery" over a period of five years.
The move marks a step forward in terms of longevity and scalability of energy storage and intensifies the competition in the sector.
The system, called Tianheng, is capable of mass production with zero attenuation in the first five years.
