Battery materials involve complex material structure, electronic state properties and ion dynamics processes. Computational calculation and simulation can predict and guide the experimental research of related battery electrode materials effectively, helping to improve the energy storage density and life of the battery.
Energy storage technology plays a vital role in promoting energy production and consumption, energy revolution and the development of new energy formats. As one of the commonly used theoretical tools, molecular dynamics (MD) simulation has indispensable value in exploring the energy storage mechanism of energy storage materials, and can provide theoretical guidance and experimental basis for the design of energy storage devices with high-performance.
Alfa Chemistry employs theoretical calculation methods in MD simulation to effectively obtain the atomic level local information between the electrode/electrolyte interface, and provide mechanism explanations for some novel experimental discoveries that cannot be directly observed through experimental methods.

At Alfa Chemistry, we apply MD simulation to study the microscopic mechanism and dynamics of energy storage from the atomic level. Our fast and high-quality services include the following:
Construct a crystal structure
Study the energy and density of ion occupancy and vacancy, and predict battery voltage
Study the lithium ion intercalation and lithiation process
Estimate the volume expansion and structural stability of the material
Calculate ion mobility
Estimate the ionic resistance of a material
Study interface electronic properties (band structure, density of states) and ion properties (ion migration)
We can simulate the dynamic charging/discharging process by applying an external bias voltage to the double-layer calculation model through the constant potential method or constant charge method calculation method.
Our experts apply MD simulation method to investigate the charge storage mechanism of energy storage materials in confined environments, which is helpful for the design of supercapacitors with high energy density and high power density.
Ion kinetics and adsorption kinetics are another key factor that affects energy storage characteristics, which directly affect the power density of energy storage devices. Alfa Chemistry can also use molecular dynamics to simulate the charging power.
