500Ah+ large battery cells appeared in large numbers at the energy storage exhibition. The industry is expected to enter a market transition period from the second half of this year to next year.

At the 15th Energy Storage International Summit and Exhibition, reporters saw that the application of 314Ah battery cells has just begun for over a year, but large batteries of 500Ah+ have already made a dense appearance at this exhibition. Many leading companies exhibited products ranging from 587Ah to 790Ah, and the speed of capacity iteration exceeded industry expectations. Business officials stated that the competition of large batteries is essentially a power struggle in the market transformation. Through double upgrades in capacity and cycle life, under the premise of controllable initial investment, the continuous decline in electricity cost is driven by a significant increase in discharge capacity. However, market switching is limited by production line equipment transformation and capacity ramp-up. It is expected to enter a concentrated switching period from the second half of this year to next year.
