“…Reports in the literature usually focused on the individual parts of the LIB cell such as the reactions between the electrolyte and the anode, solid electrolyte interphase (SEI) growth, the decomposition of cathode and anode, or lithium metal deposition on the anode [ 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 ] or on the interaction between the different materials [ 30 ]. Additionally, the operating conditions have a great influence of the degradation behavior [ 31 , 32 , 33 ]. However, the decomposition of the electrolyte is challenging to investigate due to its complex composition.…”

Quantitative electrolyte extraction from lithium ion batteries (LIB) is of great interest for recycling processes. Following the generally valid EU legal guidelines for the recycling of batteries, 50 wt % of a LIB cell has to be recovered, which cannot be achieved without the electrolyte; hence, the electrolyte represents a target component for the recycling of LIBs. Additionally, fluoride or fluorinated compounds, as inevitably present in LIB electrolytes, can hamper or even damage recycling processes in industry and have to be removed from the solid LIB parts, as well. Finally, extraction is a necessary tool for LIB electrolyte aging analysis as well as for post-mortem investigations in general, because a qualitative overview can already be achieved after a few minutes of extraction for well-aged, apparently “dry” LIB cells, where the electrolyte is deeply penetrated or even gellified in the solid battery materials.

“…As a matter of fact, the aging processes in lithium-ion cells were investigated in many papers. [12][13][14] Nevertheless, there exist rather few combined researches in the area of the processes of the thermal runaway and the aging. [15][16][17] Besides, as it was highlighted in the paper, 17 in main, the combined researches focused on influence of aging parameters on cells operation safety without a clarification of mechanisms and underlying causes.…”

In this investigation, it was shown that a probability of thermal runaway in commercial lithium-ion cells of the type 18650 grows with number increase of charge/discharge cycles and increase of cells state of charge (SOC). Notably, experiments in an accelerating rate calorimeter (ARC) showed that with the number growth of cells charge/discharge cycles, it is observed a considerable decline of an initiation temperature of exothermic reactions of thermal runaway and increase of released energy. Additional ARC-experiments with the following analysis of the gas released showed that in a course of cells cycling in anode graphite, hydrogen is accumulated. It was proven in experiments that a recombination of released-from-graphite-anode atomic hydrogen is exactly that powerful exothermic reaction, which increases the released energy in the beginning of the thermal runaway and decreases the temperature of its initiation. Thus, the reason for the initiation of thermal runaway in lithium-ion cells is a powerful exothermic reaction of recombination of atomic hydrogen accumulated in anode graphite in a during of cells cycling. The possible mechanism of initiation thermal runaway has been proposed corresponding to all the experimental results obtained. At present, lithium-ion batteries are ones of the most promising electrochemical systems of energy storing. They are dominant energy sources in hand-hold devices: smartphones, notebooks, tablets, etc.

“…In this respect, long-term cycling capability of LIBs (3000-5000 deep charge-discharge cycles) with [10][11][12][13][14][15] year calendar life is one of the major challenges. In recent years, extensive efforts have been made to fabricate and optimize electrode materials as these materials are always believed to be the key factors determining the battery performances [2][3][4][5].…”

“…However, this is far from enough. As a matter of fact, various physical, chemical and electrochemical processes occurring in the interior of batteries also greatly affect the cell performance, especially in the process of long-term cycling and storage [6][7][8][9][10].…”
