More modern battery chemistries are less hazardous as well. LFP for example is both cheaper and more stable, just at the cost of energy density. Which might be fine if you have a giant ship that can handle a large volume and mass of batteries to save on fuel costs.

TFA specifically said volume is the last thing a ship operator wants to sacrifice. Volume used for batteries is volume that cannot be used for cargo.

A huge amount of volume is already used for fuel and the engine. 2 million gallons of fuel for a Panamax is around 7,600 cubic meters.

A TEU is about 38.5 cubic meters. So that works out to about 200 TEU. A Panamax can carry about 5000 TEU worth of containers.

So all the fuel is about 4% of the cargo capacity.
