(FREE) THT: Adiabatic Calorimetry for Performance and Safety Testing of Li-Ion Batteries

This presentation describes how Accelerating Rate Calorimetry (ARC®) is the adiabatic method of choice to carry out performance and safety testing on Li-ion batteries. This technique is widely used within the industry to understand the thermal characteristics of cells.

The theoretical background of the technique is described, with recommendations made across different testing types. Examples are shown across multiple form factors, from coin cells up to small modules.

Test methods discussed include decomposition tests, nail penetration, overcharge, short circuit, infrared, optical, gas generation and analysis, heat capacity and cycling.

This webinar will focus on the following key topics:

• Principle of adiabatic calorimetry for batteries
• Advantages of this method
• Discussion of applications and results
• Recommended testing practices

A PDF copy of the presentation will be sent to all attendees after the event.

(FREE) TORAY: Cause Analysis for Performance Degradation of LIBs and Analytical Methods for All Solid-State Batteries

In Part 1, we showcase the analytical approaches of cause analysis for performance degradation of Lithium-Ion Batteries (LIBs). By the combination of electrochemical and teardown analysis, we’ll get you to find the main cause of performance degradation, and help you improve the materials optimized for the charge/discharge conditions.

Part 2 covers various analytical methods of sulfide/oxide based All Solid-State Batteries (ASSBs), in terms of composition of solid electrolyte, coverage ratio of coating layer on cathode, and component distribution in cells. In addition, brand-new analytical methods such as in situ SEM will be presented, which will expedite your R&D.

This webinar will focus on the following key topics:

• Cause analysis for performance degradation of LIBs
• Comprehensive estimation of performance degradation, and electrochemical and teardown analysis of LIBs
• Useful analysis for material development/process optimization of ASSBs
• Use cases for sulfide/oxide based solid electrolyte, and coating layer on cathode
• Cutting-edge analytical methods: in situ analysis/micro analysis

A PDF copy of the presentation will be sent to all attendees after the event.

KIM & CHANG: Next-Generation Batteries in Korea – Key Players and Legal Issues

Korean battery companies are among the world’s leaders in the field of lithium-ion batteries. However, whether these companies can maintain their leadership with next-generation batteries (such as solid state batteries) is currently unclear. We analyze the patent portfolios of the major Korean battery players to better understand what next-generation battery technologies they may be developing, and draw some conclusions regarding which players and technologies may be best placed to succeed. We also look at various legal and regulatory issues that are critical to understand when working with Korean companies and employees, particularly in view of new and proposed Korean regulations aimed at preventing leakage of cutting-edge battery technology to foreign companies.

This webinar will focus on the following key topics:

• Review of major Korean battery market players (Samsung SDI, LG Energy Solution, SK Innovations)
• Analysis of solid state battery patents with focus on Korean players
• Potential winners in the next-generation battery market
• Legal issues in working with Korean battery companies or employees

A PDF copy of the presentation will be sent to all attendees after the event.

PURDUE UNIVERSITY: Electrode Damage Characterization in Li-Ion Batteries Using Raman Spectroscopy

While Li-Ion battery technology has continually advanced to provide cells that are smaller and more powerful, compromised safety concerns due to physical damage are always present. Physical damage to a Li-Ion battery can significantly affect its operational performance, causing accelerated degradation and capacity fade. Damage to electrodes and removal of active material lead to microstructural changes in electrode material and unbalanced current distribution, causing polarization in cells. This work focuses on characterizing the effects of partial nail penetrations on electrodes in cells that continue cycling after being damaged by using Raman spectroscopy and incremental capacity analysis. This helps to determine the type and extent of damage to the electrodes over the course of their abbreviated lifetime.

This webinar will focus on the following key topics:

• Dynamic impact testing of prismatic Li-Ion cells
• Raman spectroscopy analysis for anode damage characterization
• Increased polarization due to unbalanced current distribution
• Accelerated degradation caused by physical damage
• Incremental capacity analysis to determine mechanisms of aging

A PDF copy of the presentation will be sent to all attendees after the event.
