Lithium-ion batteries consist of two lithium insertion materials, one for the negative electrode and a different one for the positive electrode in an electrochemical cell. Fig. 1 depicts the concept of cell operation in a simple manner [8]. This combination of two lithium insertion materials gives the basic function of lithium-ion batteries.
Positive electrode material of Li battery was usually a mixture of LiMn 2 O 4 and LiNi x Co 1−x O 2, since LiMn 2 O 4 has cheaper price, but shorter lifetime, LiNi x Co 1−x O 2 was more expensive, but lifetime was longer, therefore, when two of them were mixed for use, raw material cost can be reduced, however, what was more important was, moisture contained
1 Introduction. Lithium (Li) metal is widely recognized as a highly promising negative electrode material for next-generation high-energy-density rechargeable batteries
Characterizing Li-ion battery (LIB) materials by X-ray photoelectron spectroscopy (XPS) poses challenges for sample preparation. This holds especially true for assessing the electronic structure of both the bulk and interphase of positive electrode materials, which involves sample extraction from a battery test cell, sample preparation, and mounting.

Since then, the negative electrode (anode) of all the cells that have been commercialized is made of graphitic carbon, so that the cells are commonly identified by the chemical formula of the active element of the positive electrode

The dry room conditions of at least −40 °C dp ensures successfully that the remoistening of all components is minimized, so that none of them vary in their water content until the cell baking. While the final baking process, the electrode moisture contents do not drop significantly anymore.
The subsequent electrode baking decreases the moisture content for both materials. The detected water content of the anode drops from around 850 ppm w to 150 ppm w. The cathode material loses more than 100 ppm w to reach its initially detected moisture content after coating and drying.
