it is lithium iron disulfide,
http://data.energizer.com/PDFs/lithiuml91l92_appman.pdf

there are MANY types of lithium battery chemistries...what does Li-Ion really stand for ?

Li-MnO2​ (Li-Mn, "CR")
Li-SOCl2
Li-SOCl2​,BrCl, Li-BCX
Li-SO2​Cl2
Li-SO2
Li-(CF)x​ ("BR")
Li-I2
Li-Ag2​CrO4
Li-Ag2​V4​O11​, Li-SVO, Li-CSVO
Li-CuO
Li-Cu4​O(PO4​)2
Li-CuS
Li-PbCuS
Li-FeS
Li-FeS2 this is what Energizers are made of 1.7 volts
Li-FePO4
Li-Bi2​Pb2​O5
Li-Bi2​O3
Li-V2​O5
Li-CoO2
Li-CuCl2
Li/Al-MnO2
Li/Al-V2​O5
Li-ion this is Lithium Ion, 3.7 volts
Li-poly
Li–air

Wikipedia tells me the following:

Li-FeS2​Iron disulfidePropylene carbonate, dioxolane, dimethoxyethane1.6-1.4 V1.8 V297
"Lithium-iron", "Li/Fe". Used in Energizer lithium cells as a replacement for alkaline zinc-manganese chemistry. Called "voltage-compatible" lithiums. 2.5 times higher lifetime for high current discharge regime than alkaline batteries, better storage life due to lower self-discharge, 10 years storage time. FeS2​ is cheap. Cathode often designed as a paste of iron sulfide powder mixed with powdered graphite. Variant is Li-CuFeS2​.


In other words, it's another alternate chemistry. Read On

mccririck... you've been a member here for over two years now, and it seems odd that in all that time you haven't noticed we have a Batteries section for questions like this... :ironic:

Moving this there now...

Lithium ion batteries are 3.6V so how do energiser make a lithium battery that is 1.5V?

The external cell voltage is the sum of the two potentials generated by the two electrodes. The positive electrode generates one part of the voltage and the negative electrode generates the other part. The voltage at each electrode depends on the electrode material and the electrolyte (the chemical solution surrounding each electrode) in contact with it.

In a lithium primary cell like an Energizer Lithium or a CR123A the lithium metal forming the negative electrode is therefore only part of the picture. By choosing different materials for the positive electrode and the electrolyte different voltages can be produced.

Good question and good answers. Thanks, guys. It is wild how many variants of chemistries that are generically called "lithium". It is probably the primary reason for so much confusion on buying and understanding "lithium primary" and "lithium ion" batteries.
