First, 300 Wh/kg is not a laboratory scale anymore. As an example, at the IAA Munich in September 2023, CATL presented some NMC-battery (for BEV) with 186 Ah at 310Wh/kg and 760 Wh/l. Cycle Life is supposed to be >1000 cycles. CATL also presented an alternative (also for BEV) based on LFP with 126.5 Ah at 181 Wh/kg and 420 Wh/l. Cycle life ot the LFP variant is supposed to be >4000 cycles.

Second, we mentioned that in prismatic battery cells, we mostly find wrapped-up (flat winded up) anode, separator, and cathode. However, stacking seems to be becoming more popular and you could use the Z-folding method (one popular example from a variety of different stacking methods) to assemble. Imagine a zig-zag-shaped separator, anodes put in the zigs, and cathodes put into the zags of the separator. More about this in the course on manufacturing. At this point, it shall just be mentioned that stacking for prismatic Li-ion batteries is more common now than you would imagine from watching the video.
