China's 335 kg WB-LYP10000AHA Lithium-ion Battery (LIB) being developed for (or already in) China's 2nd batch of Yuan class submarines. China is also marketing this battery to Russia, presumably for Russian Kalina submarine use.

The Yuan class (Type 039A or 41) diesel-electric submarine. The first Yuans probably have Stirling AIP (and almost certainly standard lead-acid batteries).

The Japanese Navy (JMSDF) appears to be the first navy that will openly and operationally use Lithium-ion Batteries (LIBs). However China is likely to have carried out extensive trialling and assessment of LIBs mainly on converted Song class submarines. China might also be testing LIBs on Yuan class submarines in addition to the Yuan's Stirling AIP.
It is significant that China's Winston Battery company (aka Everspring or Thunder Sky) has been developing Lithium-ion Batteries (LIBs) for submarines. Chinese marketing of LIBs at: "Winston Battery WB-LYP10000AHA in large submarines"states at

"The technical information gives some ideas about the size of the battery pack for the Yuan-class of diesel-electric submarines to be equipped with an air-independent propulsion system (AIP) powered from large battery banks.
The battery pack consists of 960 pcs of the WB-LYP10000AHA cells making the total energy of 31 MWh. The lithium battery is saving some 260 tons of weight against the original lead-acid pack. With this pack the Yuan-class (B-class) diesel-electric submarine can drive 3,300 nautical miles or it can stay under water for 800 hours (33 days). This indicates the average onboard consumption of the submarine when not moving is some 38kW/h. Posted 2 years ago."

Tomorrow I will publish many details, provided by anonymous sources, on Japan's LIB's for submarine.
