The vacuum deposition limits the thickness of solid-state batteries, which, in turn, limits their energy storage capacity.

真空沉积限制了固态电池的厚度，从而限制了它的储能能力。

The other parts you see is a unit that will run off any compressor that converts it to a vacuum which is stored in a storage tank.

其他部分，你看到的是一个单位，将执行过的任何压缩机转换到一个真空，这是存储在一个储罐。

All that was needed to make a mechanical energy-storage system was a good enough rotational seal, so the flywheel could spin freely inside a vacuum chamber with no air resistance.
