Now I've taught you that battery science is straightforward and the need for grid-level storage is compelling, but the fact is that today there is simply no battery technology capable of meeting the demanding performance requirements of the grid -- namely uncommonly high power, long service lifetime and super-low cost.
现在我已经告诉了大家 电池科学是很简单的。 而且网级存储需要 是迫切的。 但事实上 现在根本还没有电池技术 能够满足 网格存储苛刻的性能要求， 即非同寻常的高功率， 长寿命 和超低成本。
