Energy storage material testing requires gold plating

Can real-time monitoring and control the plating potential in lithium-ion battery cells?

In this study, we address this challenge by introducing a novel method that involves real-time monitoring and control of the plating potential in lithium-ion battery cells throughout their lifespan.

What is UE-LSTM for plating potential estimation?

UE-LSTM for plating potential estimation For fast charging control based on plating potential, it is crucial to have a small safety margin so that the plating potential will not enter the negative region.

Why do lithium-ion batteries need a positive plating potential?

Current charging technologies often compromise one attribute for the other, leading to either inconvenience or diminished resource efficiency in battery-powered vehicles. For lithium-ion batteries, the way to meet both objectives is for the lithium plating potential at the anode surface to remain positive.

Why is a positive plating potential important?

The rationale for maintaining a positive plating potential () to prevent the initiation of lithium plating is grounded in equilibrium thermodynamics principles , , , , which are used to explain when lithium plating begins.

Why is gold plating a problem?

Another common issue is the management of the plating bath chemistry, which requires meticulous control of parameters such as pH, temperature, and the concentrations of gold and other chemicals. Any deviation can cause defects like pits, dullness, or ‘burning’ of the gold layer.

What are the different methods of calculating plating potential?

Methods to extract the information of plating potential can be categorized into three groups, including direct/indirect measurements, model-based methods, and data-driven methods , .
