Mechanical properties of cathode materials for lithium-ion batteries

Practical conversion-type titanium telluride anodes for high-capacity long-lifespan rechargeable aqueous zinc batteries

“…The increase of R ct after cycling may be attributed to the unstable interfacial contact between TiTe 2 and the electrolyte, possibly arising from the accumulation of products at the electrode interface, electrolyte decomposition, and the evolution of microcracks in TiTe 2 particles. 42–44…”

“…The increase of R ct aer cycling may be attributed to the unstable interfacial contact between TiTe 2 and the electrolyte, possibly arising from the accumulation of products at the electrode interface, electrolyte decomposition, and the evolution of microcracks in TiTe 2 particles. [42][43][44] The charge-storage contribution of the TiTe 2 electrode was identied by cyclic voltammetry (CV) tests from 0.2 to 1.0 mV s À1 . The CV curves of the non-activated TiTe 2 electrode for the rst ve cycles at 0.6 mV s À1 are shown in Fig.…”

Chemomechanics of Rechargeable Batteries: Status, Theories, and Perspectives

“…The relatively conformable solid−solid contact between SSE and cathode materials is usually achieved by the high stack pressure at room temperature. Most currently used cathode materials have a high modulus and hardness, 204 meaning the deformation during the cold pressing is small. Therefore, the major deformation needed for the conformable solid−solid contact should be compensated by the SSEs.…”

A coupled phase field formulation for modelling fatigue cracking in lithium-ion battery electrode particles

“…Unless otherwise stated, the characteristic length of the phase field is chosen to be l = 0.01 µm, following [21,22]. Characterising electrode particle behaviour is challenging but improved insight has been recently gained through nanoindentation [55] and image-based modelling techniques [56]. The initial crack is introduced by applying a non-zero history field H to the local crack partition domain at t = 0, using…”
