avahwatt also hopes to achieve differentiated competition in energy storage through the technical route of lamination + dagger.
For customers with high capacity and low cost requirements, the cost of a 350Ah battery cell with a slightly reduced cycle life of 8,000 cycles can be reduced by 5% to 10%. Meet the needs of companies that do not require that long life but are very cost-sensitive.
For example, if you need a larger capacity, you can double the thickness of the 325Ah battery core to reach 710Ah and cycle for 8,000 cycles.
These two batteries will be mass-produced in Q3 next year and Q1 in 2025.
avahwatt is based on the same size and the same production line, downgrading the 325Ah battery cell to 310Ah, which can achieve 12,000 cycles and 11,000 cycles.
In this way, 6 different product layouts can be realized to meet the needs of different products through a high degree of unified platform and extremely low production line investment.
In addition, avahwatt has also launched a highly platform-based product matrix of modules. It will launch the first standardized container product assembled using large-capacity, short-blade laminations, which is expected to reduce system costs by 5% to 10%. The installed capacity of a single container up 15% to 20%.
The advantage of sodium-ion batteries is that they have good low-temperature performance. The low-temperature capacity retention rate is at minus 30 degrees and minus 40 degrees, which is far better than lithium-ion batteries. However, its disadvantage is that the discharge power is relatively small and the discharge is slow, so it has not yet found a suitable application scenario, and they are still exploring.
The semi-solid jelly battery released at the first Battery Day has now entered its second generation, which is completely different from the first version. In terms of material system, high nickel and silicon negative electrodes are still used, which currently solves the expansion and gas generation problems of high nickel and silicon negative electrodes.
