Lithium

Table 1. Li 1s values from a compilation of literature sources [1].

Table 2. Li 1s values from standards run in this laboratory [2].

Notes:
Lithium is quite reactive to air and water.  The use of inert gas filled gloveboxes to minimize exposure is important here.

Anion values:
F 1s in LiF = 685.5 +/-0.7 eV (7 references), 685.1 +/-0.1 eV (standard samples from Table 2).
O 1s in Li2O = 531.3 eV (1 reference).
O 1s in LiOH = 531.2 +/-0.2 eV (2 references).
O 1s in LiCO3 = 531.5 +/- 0.1 eV (2 references) (confirm presence with C 1s carbonate peak).
Cl 2p3/2 in LiCl = 198.6 +/- 0.1 eV (standard samples from Table 2).
O 1s in Li3PO4 = 531.3 +/- 0.1 eV (standard samples from Table 2).
P 2p3/2 in Li3PO4 = 133.3 +/- 0.1 eV (standard samples from Table 2).
