The Chinese Everspring advertisement for Lithium-ion Battery (LIB) use by submarine carries the above photo - what appears to be a (or the) Type 092 Xia class SSBN. The description "48 hours continuously under the water of 1,000 meters for one charge" suggest the batteries are for emergency backup if a submarine reactor fails. "1,000 meters" is very deep diving!

In Submarine Matters Russian Submarine Industry - Lada discontinued - no AIP -LIBs? of 28 January 2016 I commented:
The comments that followed, such as from KQN, prompted me to do a bit of research. I located Everspring Global Limited:
"Everspring Global Limited is an authorized distributor of
Thunder Sky Battery Limited or Winston Battery Limited, since 2001.

BUT CAN RUSSIA HOLD UP ITS SIDE?
"The world’s largest lithium-ion battery plant,
a joint venture between
the Chinese lithium battery manufacturer Thunder Sky Group and Russian state
run agency RUSNANO, was
recently opened in Novosibirsk, Russia. Novosibirsk is a heavy industrial (including aerospace and nuclear) Russian city in southwestern Siberia which is increasingly into IT.
…The Liotech commercial venture has already reported to have signed a
number of contracts to supply lithium batteries. Chief Executive Officer of
Liotech Alexander Erokhin indicated that the
company has seen interest in Liotech lithium batteries from businesses in the
Russian military industrial complex..."
---------------------------------
[Comment - In 2014 China was the world's third largest Lithium producer and second largest reserves. Russia wasn't listed. But trade sanctions (perhaps targeting dual-use
technologies like LIBs) and low oil prices means Russia, with its lower value ruble, cannot ensure Lithium supplies for LIBs.
for InvestorIntel
reports Russia
focused on securing stable lithium supply as demand for products grows, January 4, 2016:
"The Russian
government plans to create conditions for a significant increase in
lithium production and lithium products during the next several years.
According to
Yuri Gerner, Director General of the Novosibirsk Chemical
Concentrates Plant (NCCP),
one of the world’s leading manufacturers of the nuclear fuel for NPPs and for
research reactors, the majority of global producers of lithium products have
their own raw material base, which allows them to significantly save on
production costs, however Russia, to date, has experienced serious problems
with stable lithium supplies.
According to
an official spokesman of Denis Manturov, Russia’s Minister of Industry and
Trade, (a person, who is responsible for the development of lithium industry in
the Russian government), lack of the domestic raw material base seriously
restricts the ability of Russia to produce lithium products at competitive
cost.
The situation
is aggravated by the ongoing economic crisis in Russia and the devaluation of
the national currency – ruble, which results in a significant increase of the
cost of raw material.
...In addition to
the supplies of raw materials, a particular attention will be paid for the
increase of production of lithium-ion batteries in Russia."
A clear 2011 technical explanation of LIBs from Liotech, joint Russian RUSNANO - Chinese Thunder Sky venture.

Eugene Gerden continues: "One of such
projects is expected to be re-launched by Liotech, a subsidiary of Russia’s
nanogiant Rusnano, which involves the resume of the operations of the existing
Russian plant for the production of lithium-ion batteries.
The plant was
built by Liotech in cooperation with the Chinese Thunder Sky during the period
of 2009-2011, while total amount of investments in the project exceeded 13.5 billion
rubles (US$300 million).
According to
initial plans of Liotech, the design capacity of the plant should be 400
million ampere-hours. Thunder Sky had
promised to acquire the 85% stake of the plant, however decided to leave the
project at the beginning of 2013. In summer 2014 Liotech decided to suspend its
production, due to a significant decline of demand for its production in the
domestic market, caused by the financial crisis in Russia.
…In addition, there are also plans for the
active use of lithium-ion batteries in the Russian defence industry, and in particular in the production of
unmanned vehicles and other combat equipment and weapons."
PETES COMMENT
So China (with Thunder Sky - Winston - Everspring) appears to have the intention, money and Lithium supplies to develop LIBs for submarine. LIBs as an emergency backup for SSBN and probably SSN reactors. This may be a step towards full LIBs for SSKs (diesel-electric subs) such as an Improved Yuan class.
Russia (with Liotech) may be the junior partner in a joint Chinese-Russian LIB effort. Russia may have the intention but not the money or Lithium supplies given its current economic problems.
Russia may, however, be able to barter its higher technical know-how (especially in nuclear subs and reactors) for Chinese LIBs or for more Chinese backing of Liotech.

I believe Lithium ion battery is going to become a standard feature on submarines. LiFePO4 is already widely used in sail boats. The Chinese dope the cathode in those batteries with Ytrium to increase battery performance and it seems they are testing/using LiFeYPO4 in their nuclear submarines. Ytrium in some states can be hazardous to human.
Where performance matters, like electric cars, electric bicycles or motorcycles or solar planes and submarines, lithium ion will be inevitable. Australia should create a test bed with lithium ion batteries based on the Collins electrical design, initially on land which could later be tested in a Collins. That will allow you to formulate an independent assessment of the technology.
I do not see Lithium ion bateries to be in conflict with AIP or nuclear power in submarines.
There is one type of AIP which can play to Russia's expertise. It is with radioisotope thermo-electric generators. The RTG AIP design has been tested or is being tested in the Sarov submarine. Sarov is a research submarine based on the Kilo hull but stretched to 98m. RTG basically convert heat from waste nuclear materials to electrical energy by using either thermocouples (not very efficient to scale up) or a Stirling engine (US research) or a turbine generator (as in all nuclear submarines). RTG is extensively used in satellites. The Kristall AIP has also been tested in the Sarov back in 2012 according to one PR I saw.

@KQN:
My understanding was that RTGs were able to generate power in the range of tens to hundreds of watts, not the several hundred kilowatts generally provided by AIP arrangements in deployed boats. While RTGs have provided power for many space probes (Curiosity being the most current I can think of) I don't believe they can deliver sufficient power to function as an AIP source for a manned submarine. I've also only heard of the thermocouple mechanism; do you have any links to RTGs being used with mechanical engines? I'm not sure what the target application would be; perhaps persistent UUVs. My cursory search of the Sarov online indicates it actually uses a full nuclear reactor, not RTGs:
