Summary: The electrochemical Li/Na/K-ion reaction pathways in Ga for high-performance Ga anodes in alkali-ion batteries are thoroughly elucidated using ex situ analytical tools. Ga exhibits a high Li-ion storage reaction, forming Li2Ga, but poor Na- and K-ion storage reactions, forming NaGa4 and K3Ga13, respectively. An amorphous Ga composite (Ga/C) is fabricated, showing high reversible capacity, long-term Li-ion storage stability, and high rate capability. Three-step confinement of amorphous Ga in the composite during cycling is demonstrated as an enhancement mechanism for high-performance Ga/C anodes for LIBs.

Summary: This study proposes a cost-effective method to regenerate LiBH4 by ball milling hydrous lithium metaborate with low-cost Mg-based alloys. The introduction of light rare-earth metals into Mg improves the regeneration kinetics of LiBH4 by facilitating the breakage of B-O and conversion of H+ into H-. A yield of 40% can be achieved for LiBO2 center dot 2H(2)O-CeMg12 system with a relatively short ball milling duration of 10 hours. The optimized regeneration of LiBH4 is believed to be efficient and economical, utilizing an intrinsic hydrogen source in LiBO2 center dot 2H(2)O and cheap reducing agents. This finding is expected to promote the widespread use of LiBH4 for hydrogen storage.

Summary: The austenite to ferrite phase transformation is a crucial structural change in steel production, with the ferrite morphology and grain size significantly impacting the mechanical properties of steel materials. This study investigates the effects of cooling rate, prior austenite grain size (PAGS), and Mn content on the microstructure evolution of the austenite-to-polygonal ferrite phase transformation using a multi-phase-field model. The findings reveal that higher cooling rates enhance the driving force for the phase transformation and delay the process. Decreasing PAGS increases the proportion of austenite grain boundaries, providing more nucleation sites for polygonal ferrite and resulting in refined grain size. Furthermore, increased Mn content leads to significant grain refinement by reducing the transformation temperature. This work provides valuable insights for adjusting and designing desired microstructures of polygonal ferrite to enhance the mechanical performance of steel.

Summary: To improve the conductivity and stability of solid-state lithium batteries, a sandwich-structured composite polymer electrolyte (sandwich-CPE) PEO-TiN/PEO-LiYF4/PEO-TiN was developed. The sandwich-CPE exhibited high ionic conductivity and a wide potential window. Addition of PEO-TiN effectively reduced the formation of Li dendrites and acted as a sacrificial layer to prevent dendrites from entering the interlayer PEO-LiYF4. Using the sandwich-CPE, different cathodes showed high reversible capacity and good cycling stability at various temperatures and current rates.
