Artificial intelligence (AI) and machine learning (ML) is becoming popular in many fields including using it for lithium-ion battery research. These methods have been used in all aspects of battery research including materials, manufacturing, characterization, and prognosis/diagnosis of batteries. [1]
The equivalent circuit model (ECM) is a common lumped-element model for Lithium-ion battery cells. [1] [2] [3] The ECM simulates the terminal voltage dynamics of a Li-ion cell through an equivalent electrical network composed passive elements, such as resistors and capacitors, and a voltage generator.
A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life.
A research concept has been proposed in which the major parts of lithium-ion batteries, that is, the anode, electrolyte, and cathode, are combined into one functional molecule. A layer of such functional molecules aligned by the Langmuir-Blodgett method is placed in between two current collectors. [5] The feasibility has not been confirmed yet.
A battery balancer or regulator is an electrical device in a battery pack that performs battery balancing. [2] Circuitry that includes designs to balance cell charges during battery pack recharging may be either active or passive in its design, [ 3 ] and is most often found in lithium-ion batteries , [ 4 ] e.g., for laptop computers, electrical ...
Excessive porosity hinders the ability of the pores to close, which is vital to allow the separator to shut down an overheated battery. Porosity can be measured using liquid or gas absorption methods according to the American Society for Testing and Materials D-2873. Typically, a Li-ion battery separator provides porosity of 40%.
