Summary: This study investigates the controlled non-localized brittle fracture of a periodic beam-lattice under tensile loading. It is found that the lattice material exhibits a partially broken but not failed paradigm, which allows for energy absorption while maintaining structural integrity. Comparing different lattice configurations, an anisotropic lattice with triangular cells and a bone-microstructure inspired lattice with rectangular cells are found to have better energy absorption properties.

Summary: Anode materials with high energy and power density are urgently needed for lithium ion batteries. In this study, a new secondary hard carbon microsphere (CMS) anode material inspired by layered oxide cathode was designed, showing excellent rate performance and long cyclability. The carbonized CMS from polyacrylonitrile/poly (styrene-co-acrylonitrile) (PAN/SAN) compositions exhibited high specific capacity at 1,000 mA g-1, i.e., 77.6% of its average charge capacity at 100 mA g-1, and considerable cycling retention after 500 cycles, i.e., 83.8% of the specific capacity at cycle 25. This work highlights the importance of designing new anode materials to improve commercial Li-ion batteries.

Summary: This study presents a bench-top bio-inspired breastfeeding simulator (BIBS) integrated with a software interface and feedback control techniques to simulate infant-breast interaction during breastfeeding. The modified BIBS setup includes a solid infant head model and microcontroller-based proportional-integral-derivative controls for vacuum pressure and motor speed tracking control. Multiple measurement systems and a graphical user interface (GUI) are used to obtain and display real-time data. Experimental tests confirm the fidelity and robustness of the new BIBS in mimicking multi-phase infant oral suckling dynamics. The simulator serves as a testbed for understanding the biomechanics of breastfeeding.

Summary: Electric vehicles powered by Li-ion batteries can be dangerous due to the flammable liquid electrolytes, but all-solid-state batteries offer a safe alternative. This study demonstrates that B-doping and coating of a Ni-rich Li[Ni0.9Co0.05Mn0.05]-O2 cathode can enhance the microstructure and cathode-solid electrolyte interface, resulting in an all-solid-state battery that cycles stably for 300 cycles with minimal capacity fading. The B-doped, B-coated Li[Ni0.9Co0.05Mn0.05]O2 cathode achieves a discharge capacity of 214 mAh g-1, one of the highest among all-solid-state batteries, and retains 91% of its initial capacity after 300 cycles, surpassing previously reported all-solid-state batteries in terms of energy density without compromising cycling stability.

Summary: Through comparing the electrochemical performance of Li[Ni0.92_xCo0.04Mn0.04Alx]O2 cathodes, a high-performance Ni-rich Li[Ni1_x_y_zCoxMnyAlz]O2 (NCMA) is developed with optimal Al content. The introduction of excess Al results in a refined cathode microstructure, effectively dissipating strain and suppressing the formation of internal cracks. A full cell featuring the optimized NCMA cathode demonstrates excellent long-term cycling stability and energy density, outperforming existing layered cathodes. This research represents a new class of Ni-rich layered cathodes suitable for high-performance electric vehicles.

Summary: By doping with tantalum, the CS-type cathode encapsulates the Ni-rich region with a Ni-less shell, effectively improving the cycling stability of the cathodes. Ta doping suppresses interdiffusion by segregating the Ta-rich phases at the particle boundaries, maintaining the highly aligned microstructure and the ordered intermixing structure, as well as the concentration gradient, over a wide lithiation temperature range. The Ta-doped CS-type cathode retains 92.6% of its initial capacity after 1000 cycles and exhibits resistance to damage from fast charging.

Summary: The study proposes a washing process using Co-dissolved water to remove residual lithium and form a protective coating on the Ni-rich layered cathodes. The washing process induces near-surface structure reconstruction and prevents direct contact between the electrolyte and the cathode surface. The addition of a fluorine coating on the washed cathode suppresses by-product decomposition and gas generation during cycling, resulting in extended cycle lives of the cathodes and meeting the requirements of energy density, durability, and safety for next-generation batteries.
