About Paper:

Lithium-ion batteries are widely used in various applications due to their high energy density, long cycle life, and lightweight design. These batteries are commonly found in portable electronic devices, electric vehicles, and energy storage systems. The continual improvement of Li-ion battery technology relies on extensive electrochemical and materials science research. These research activities often involve a series of analytical studies focused on understanding how the electrodes have degraded after cycling the battery under different operational conditions. For Li-ion cells having a metallic outer casing, such as the common 18650 format, dissection for analysis of electrode materials can prove to be problematic. Mishandling or improper disassembly of these batteries can pose safety risks, such as thermal runaway and the release of toxic substances. Safe dissection of a live Li-ion cell should occur in a well-ventilated area using appropriate personal protective equipment while avoiding mechanical damage to the battery. The primary focus for this study is to create a safe dissection mechanism which allows the operator to easily harvest electrode materials from 18650 format cells without damaging or overheating the active materials within the cell.
