Background In 2010, the rechargeable lithium ion battery market reached ~$11 billion and continues to grow. 1 Current demand for lithium batteries is dominated by the portable electronics and power tool industries, but emerging automotive applications such as electric vehicles (EVs) and plug-in hybrid electric vehicles (PHEVs) are now claiming a share.
In a lithium-ion battery, both electrodes are atomic frameworks that host mobile lithium ions. When the battery is being charged or discharged, lithium ions diffuse from one electrode to the other. Such an insertion reaction deforms the electrodes and may cause the electrodes to crack. This paper uses fracture mechanics to determine the …
