A group from Yanshan University report the synthesis of a bulk BN ceramic composed of three-dimensional interlocked BN nanoplates whose vdW layers form a laminated structure with various twisting angles. The twisted-layer bulk ceramic was synthesized from onion-like BN (oBN) nanoparticles using conventional spark plasma sintering (SPS) and hot-pressing sintering.

The lithium metal cells with high energy density (> 500 Wh kg⁻¹) are regarded as the main technology route of the next generation of high-performance cells. The development of practical lithium metal cells is plagued by their limited lifespan, primarily due to the poor interfacial stability of the electrolytes.
