Analysis of Lithium-Ion Battery Cycle Degradation Using DRT Method

Electrochemical Impedance Spectroscopy (EIS) can be used to analyze the internal electrochemical processes of lithium-ion batteries. The data is generally fitted using an Equivalent Circuit Model (ECM) to extract parameters related to specific electrochemical processes. Due to the difficulty in separating various electrochemical processes in EIS, the Distribution of Relaxation Times (DRT) method has been … Read more

Calculating DRT

After understanding the basic concept of DRT, the remaining question is how to determine the time distribution function. It was previously mentioned that directly finding the minimum of S(x) to obtain the time distribution function is an ill-posed problem. To address this issue, we use ridge regression to handle the overfitting problem. This method introduces … Read more

Antithrombotic Treatment Strategies After Left Atrial Appendage Closure: Current Evidence and Future Perspectives

*For medical professionals only The left atrial appendage closure (LAAC) is an effective alternative treatment to long-term oral anticoagulants (OAC) for preventing thromboembolic events related to non-valvular atrial fibrillation (AF). However, antithrombotic therapy is required after LAAC to prevent device-related thrombus (DRT). The optimal antithrombotic strategy post-LAAC remains unclear. LAAC has been in use for … Read more
