“…Learners should not be confused by negative axes and twisted coordinate systems in the literature. For a cycle life test on a new battery, the real part, imaginary part, and the capacitance at the semicircle's minimum 3 show a clear but nonlinear dependence on the SOC and SOH (Figure 9). The exact circular frequency at the minimum, ω m = 2π f m , was determined by cubic spline approximation.…”

“…In recent years, the monitoring of lithium-ion batteries [1,2] under normal and hazardous operating conditions has become increasingly important, whether in technical applications or for the development of new materials in laboratory cells (e.g., [3][4][5]). For SOC and SOH estimation, charge-discharge curves are traditionally used, and more recently also impedance spectra.…”

State-of-charge (SOC) and state-of-health (SOH) of different cell chemistries were investigated using long-time cycle tests. This practical guide illustrates how differential capacity dQ/dU (capacitance) obtained from discharge curves, impedance spectra, and cyclic voltammograms can be used for the instant diagnosis of lithium-ion batteries without fully charging and discharging the cell. The increase of dU/dQ is an early indicator of upcoming heat events and deep discharge. The criterion dQ/dU = dU/dQ = 1 could serve as an indicator for “full charge”. The frequency response of capacitance correlates with the available charge of the battery and reflects overcharge events and deep discharges long before the battery fails. It is not necessary to measure down to extremely low frequencies because the charge transfer pseudocapacitance of around 10 Hz reflects well the SOC. Computer-aided calculation methods for the evaluation of measurements in industrial environments and for the training of students are presented.

“…Compared with traditional lithium-ion battery materials, it is an ideal material for power lithium batteries because of its wide source of raw materials, outstanding safety performance, good cycling performance, good thermal stability, low cost, and no environmental pollution [1][2][3]. As a general rule, LiBs are made of an anode, a cathode, current collectors, a separator, liquid electrolyte, container, and sealing parts [4][5][6].…”

With the widespread use of lithium iron phosphate batteries in various industries, the amount of waste lithium iron phosphate batteries is also increasing year by year, and if not disposed of in a timely manner, will pollute the environment and waste a lot of metal resources. In the composition of lithium iron phosphate batteries, the cathode has an abundance of elements. The ultrasonic method is a crucial method to recover waste LiFePO4 batteries. It has the following disadvantages, such as the lack of empirical parameters and suitable research equipment. In order to overcome the inefficiency of the LiFePO4 recycling method, the airborne bubble dynamical mechanism of ultrasound in the removal of lithium phosphate cathode material was studied by a high-speed photographic observation and Fluent simulation and the disengagement process. Mainly aimed at the parameters such as action time, power, frequency, and action position in the detachment process were optimized. The recovery efficiency of lithium iron phosphate reached 77.7%, and the recovered lithium iron phosphate powder has good electrochemical properties, with the first charge–discharge ratio of up to 145 (mAh)/g. It is shown that the new disengagement process established in this study was adopted for the recovery of waste LiFePO4.

Summary As an essential class of anode materials, the synthesis and characterization of CoS@ZIF‐12‐C composite anode materials are reported. The two‐step synthesis of CoS nanoparticles embedded in N‐doped porous carbon by using a metal‐organic framework (MOF) as the template. After structural characterization of CoS@ZIF‐12‐C composite materials, the main phase was found as CoS with symmetry of P63mmc. Benefiting from the CoS embedded in porous carbon structure, the half Li‐ion battery cell tests of CoS@ZIF‐12‐C composite materials were performed by a 2‐electrode method using CR2032 cells, and the capacities of the cells were measured for 200 cycles using 300 mAg−1 and 500 cycles using 1000 mAg−1. The first discharge capacities of the cells for 1000 mAg−1 were found as 458, 1178, and 815 mAhg−1 for CoS@ZIF‐12‐C‐T, T = 700, 800, and 900°C, respectively. An unexpected capacity increase was observed for the CoS@ZIF‐12‐C‐700 and CoS@ZIF‐12‐C‐900 half cells during the cycling. Ex‐situ x‐ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), and cyclic voltammetry (CV) analysis were performed after cycling of the cells for explanations of the capacity increase. Ex‐situ XRD analysis of these cells showed phase transitions from crystalline to amorphous type structure, and ex‐situ FTIR proves the preservation of the CoS phase during the cycling. A redox reaction mechanism was suggested to explain the cells' battery performance by ex‐situ XRD analysis.
