Hydrogen vs. Battery Electric Cars

The problem with BEV's vs FCEV's is the recyclability of the (usually) lithium-ion batteries in BEV's.
Currently Tesla and many other companies claim that they are able to recycle roughly 50% of a BEV's batteries. 
But this is a pure sham. 
The plastic casing that prevents overheating, the cabling inside, and all other components in a lithium-ion car-battery make up roughly 50% of the weight of such a battery.
The actual lithium is rarely, if ever, recycled. But the lithium is the part that is the most expensive, yet also the most difficult to recycle.

To recycle the lithium would incur a cost that is higher than currently purchasing new lithium on the global market. Which means that Tesla and many of the other companies investing in BEV's are NOT recycling their batteries at all. But they fulfil the government level mandate by recycling the stuff that is easy to separate into its components, and easy to recycle: the casing.
