Lithium-ion Li-ion cells degrade after repeated cycling and the cell capacity fades while its resistance increases. Degradation of Li-ion cells is caused by a variety of physical and chemical mechanisms and it is strongly influenced by factors including the electrode materials used, the working conditions and the battery temperature. In this paper, a method to fit and analyze the charging voltage curve based on a neural network is proposed and is compared to the existing point counting method and the polynomial curve fitting method. The neuron parameters of the trained neural network model are used to analyze the battery capacity relative to the phase change reactions that occur inside the batteries. This method is suitable for different types of batteries and could be used in battery management systems for online battery modeling, analysis and diagnosis.

The energy density of canode materials for lithium-ion batteries has a major impact on the driving range of electric vehicles. Firstly, a set of charge-discharge experiments were performed on different types of single-cell lithium-ion batteries. The results show that, under temperature conditions, the charge and discharge voltage-capacity curves of the four different types of Li-NiMnCo lithium batteries mentioned in the paper are not much different, and the charge-discharge characteristic curves are similar, indicating that different types of batteries with the same material composition have similar charge and discharge characteristics. Subsequently, a series of charge and discharge tests with different rates were conducted on such ternary lithium batteries. The characteristic curves with different charge-discharge rates indicate that this new type of ternary lithium battery has high current charge and discharge capability and is suitable for use in new energy electric vehicles.

The growth of devices running on lithium-ion batteries has created demand for high levels of precision and quality to support various applications. The test objective is to determine the number of times a battery can be used by evaluating it until it deteriorates after repeated cycles of charging and discharging. The standard method is to charge and discharge repeatedly at the recommended charge and discharge rates. Temperature cycle testing is also often performed, in which the test temperature is raised and lowered by placing the sample in a temperature chamber.

Lithium batteries are primary batteries that have metallic lithium as an anode. These types of batteries are also referred to as lithium-metal batteries. They stand apart from other batteries in their high charge density and high cost per unit. Depending on the design and chemical compounds used, lithium cells can produce voltages from 1. Disposable primary lithium batteries must be distinguished from secondary lithium-ion or a lithium-polymer , [1] which are rechargeable batteries.

A rechargeable battery , storage battery , or secondary cell , or archaically accumulator is a type of electrical battery which can be charged, discharged into a load, and recharged many times, as opposed to a disposable or primary battery , which is supplied fully charged and discarded after use. It is composed of one or more electrochemical cells. The term "accumulator" is used as it accumulates and stores energy through a reversible electrochemical reaction. Rechargeable batteries are produced in many different shapes and sizes, ranging from button cells to megawatt systems connected to stabilize an electrical distribution network. Several different combinations of electrode materials and electrolytes are used, including lead—acid , zinc-air , nickel—cadmium NiCd , nickel—metal hydride NiMH , lithium-ion Li-ion , Lithium Iron Phosphate LiFePO4 , and lithium-ion polymer Li-ion polymer. Rechargeable batteries typically initially cost more than disposable batteries, but have a much lower total cost of ownership and environmental impact , as they can be recharged inexpensively many times before they need replacing. Some rechargeable battery types are available in the same sizes and voltages as disposable types, and can be used interchangeably with them.
