In the quest for longer term safer Lithium battery solutions
for submarines it is pointed out existing Lithium ion batteries (LIBs) mostly use electrolytes in organic liquid solution, while Lithium polymer (Li-Po) batteries use electrolytes in polymer
gel (semi-solid) solution.
Li-Po is safer than existing LIBs due to the properties of polymer gel.
Li-Po is a polymer gel version of LIBs. There are many types of
Li-Po, such as Li-Po NMC (lithium nickel manganese cobalt oxide).
Dutch battery manufacturing company EST-Floattech
is commercializing Lithium Polymer (“Green
Orca”) batteries for marine applications.
Green Orca Modules use EST-Floattech partner Kokam’s
Li-Po NMC pouch cells. The brochure below indicates: "The technical design choices for
the Green Orca® [energy storage system] ESS started with a high performance Li-Ion battery cell and
resulted in the world’s safest, DNV-GL certified Li-Ion ESS." Further down the NMC
chemistry has a “high energy density and
overall strong performance while the pouch shape ensures better heat
dissipation resulting in excellent efficiency”. See further details in
the brochure at [1].

An energy module (weighing 82 kg) consists of 14 cells, its size is W x H x D =
335 mm x 541 mm x 542 mm. Its capacity is 10.5kWh (14 cells x 200Ah x 3.7V =
10.36kWh). Capacity per weight is 126Wh/kg (10.36kWh/82kg) [with a Cycle
Life of approximately "4,600 cycles"]. Capacity of Lithium Iron Phosphate is 90-120Wh/kg.
Anonymous’ Estimated Arrangements in a future SAAB-DAMEN modified A26 submarine:
Example A - Two battery sections with module arrangement of
double stacking, 12 rows and 20 lines
of module. Total number of batteries is
960 (= 2 sections x 12 rows x 20 lines
x 2 stacks). This would yield total power
capacity is 9.94 MWh.
Example B - Two battery sections with module arrangement of
triple stacking, 12 rows and 20 lines
of modules. This would yield total power
capacity 14.9 MW.
