It is commonly accepted that Li-ion battery life

is limited by the process of degradation of electrode

materials with repeated charging and discharging. During

battery operation, lithium ions are shuttled between

cathode and anode when the battery is being charged and

discharged. One of the degradation mechanisms is related

to the development of internal stresses in electrode

particles due to repeated lithium insertion and removal.

The stresses ultimately result in cracks in and fracture of

particles. The current project targets the fundamental

understanding through controlled experimental work of

internal stress generation in and morphology change of

electrode particles in Li-ion batteries.
