This offers advantages for high energy density and alleviation of cathode side reactions/corrosions, but introduces drawbacks such as intergranular cracking. Here, we report unexpected observations on the nucleation and growth of intragranular cracks in a commercial LiNi<jats:sub>1/3</jats:sub>Mn<jats:sub>1/3</jats:sub>Co<jats:sub>1/3</jats:sub>O<jats:sub>2</jats:sub> cathode by using advanced scanning transmission electron microscopy. We find the formation of the intragranular cracks is directly associated with high-voltage cycling, an electrochemically driven and diffusion-controlled process. The intragranular cracks are noticed to be characteristically initiated from the grain interior, a consequence of a dislocation-based crack incubation mechanism. This observation is in sharp contrast with general theoretical models, predicting the initiation of intragranular cracks from grain boundaries or particle surfaces. Our study emphasizes that maintaining structural stability is the key step towards high-voltage operation of layered-cathode materials.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383388845653629952","@type":"Researcher","foaf:name":[{"@value":"Pengfei
