Abstract A review of the prevalent degradation mechanisms in Lithium ion batteries is presented. Degradation and eventual failure in lithium-ion batteries can occur for a variety of dfferent reasons. Degradation in storage occurs primarily due to the self-discharge mechanisms, and is accelerated during storage at elevated temperatures. The degradation and failure during use conditions is generally accelerated due to the transient power requirements, the high frequency of charge/discharge cycles and differences between the state-of-charge and the depth of discharge influence the degradation and failure process. A step-by-step methodology for conducting a failure analysis of Lithion batteries is presented. The failure analysis methodology is illustrated using a decision-tree approach, which enables the user to evaluate and select the most appropriate techniques based on the observed battery characteristics. The techniques start with non-destructive and non-intrusive steps and shift to those that are more destructive and analytical in nature as information about the battery state is gained through a set of measurements and experimental techniques.

Cathode material Li[Ni1/3Co1/3Mn1/3]O2 for lithium-ion batteries with layered hexagonal structure was successfully synthesized in sol-gel way. The influences of calcination temperature (from 700° to 1000°C) on the structure and electrochemical behaviors of Li[Ni1/3Co1/3Mn1/3]O2 were extensively investigated. The results of XRD show that all samples are isostructural with α-NaFeO2 with a space group R-3m. XPS analysis shows that the oxidation states of Co and Mn were Co3+ and Mn4+ respectively, while Ni exists as Ni2+ and Ni3+. The charge-discharge experiments show that the sample calcined at 850°C delivers 194.8mAh/g in the first cycle at C/5 rate in 2.5-4.3V potential range.

Problem statement: Currently, there is a need in the space industry to actively improve the characteristics of battery batteries, the use of new types of batteries for power supply systems of spacecraft leads to a constant demand to improve the control and verification equipment (CPA). Depending on the improvement of storage batteries (AB) for spacecraft, the requirements for electrical inspections and control and verificationequipment were gradually changed. With the advent of lithium-ion batteries for spacecraft, there was a need to develop and manufacture a charge-discharge hardware and software complex (ZRPAK). The charge-discharge hardware-software complex designed to work as a charger-bit complex to work with AB spacecraft for all ground operation phases, to verify compliance of the electrical characteristics of the AB to the specified requirements, conduct incoming inspection and Autonomous tests of AB on the manufacturer of the spacecraft. The advantages and disadvantages of the previously developed and currently used control and verification equipment are analyzed. The electrical characteristics of the KPA of all generations of development are summarized in the table. Based on the analysis of the development of batteries, trends in the development of control and verification equipment and the fact that all spacecraft of new developments will use only lithium-ion batteries, the requirements for a promising fifth-generation ZRPAK are formulated. The following requirements are applied to the fifth-generation charge-discharge software and hardware complex: increase the charge-discharge voltage to 150 V; increase the charge -discharge current to 150 A; introduce devices for pre-charge-pre-discharge of the battery into the KPA; increase the accuracy of measuring the voltage of each battery; provide remote operation from the control PC; writing cyclograms; logging and subsequent viewing of all test data

Abstract A new process decomposed calculation method is developed to compare the cycle based charge, discharge, net, and overall energy efficiencies of lithium-ion batteries. Multi-cycle measurements for both constant current (CC) and constant current to constant voltage (CC-CV) charge models have been performed. Unlike most conventional efficiency calculation methods with one mean open-circuit voltage (OCV) curve, two OCV curves are calculated separately for the charge and discharge processes. These two OCV curves help to clarify the intra-cycle charge, discharge, net, and overall energy efficiencies. The relationships of efficiencies versus state of charge, state of quantity, and scaled stresses are demonstrated. Efficiency degradation patterns versus cycle numbers and scaled stresses are also illustrated with the artificial neural network (ANN) prediction method. The decaying ratios of the overall efficiencies are about 2% and 0.3% in the first 30 cycles, for CC and CC-CV, respectively. Hence, efficiencies of the CC-CV model are more stable compared with the CC model, which are shown by both experimental and ANN prediction results.
