The following is drawn from Anonymous' statements in the Comments section below.
There are important propulsion components in the Oryu (27SS) the first Soryu Lithium-ion Battery (LIBs) submarine, that allows its (NCA (see Table below)) LIBs to function in the most efficient way.
These components include, faster run rates of its two Kawasaki 12V25/25SB diesel engines, a more powerful SMC-8B propulsion motor and a more powerful snorkel system (with higher volume/minute intake of air and higher expulsion of exhaust gases).
Oryu’s charge rate of its LIBs is much faster than could be achieved if it had traditional lead-acid batteries (LABs). This gives Oryu a more discrete, shorter time needed to snort/snorkel for the same (or greater) fully submerged operation.Discrete means Oryu operates more quietly overall.
Also see NCA by scrolling a quarter-way down in the Battery University website.

Two routes of advanced LIBs development may be as follows:
Route 1 LABs --- First Gen LIBs --- Second Gen LIBs --- LSBs
OR
OR
Route 2 LABs--- First Gen LIBs --- LSBs
