A coupling design of novel Li 7 TaO 6 surface buffer coating with bulk Ta-doping for the NCM811 cathode controllable thickness is successfully synthesized by a simple and scalable method, demonstrating excellent long-life performance in sulfide-based ASSLBs.
Abstract The reaction chemistry and degradation mechanism of MnO 2 ‐based cathodes remain controversial, which hinder their applications in energy storage. Herein, a conversion between Zn 4 SO ·(OH) 6 · n H O (ZSH) x MnO(OH) (ZMO) is proposed ZnSO electrolytes. an important component the as well 2+ /H + intercalation/deintercalation reaction, not only provides electrochemical capacity but also dominates cathodes. massive accumulation inactive ZMO seriously destroying dynamic performance...
Abstract Structural damage of Ni‐rich layered oxide cathodes such as LiNi 0.8 Co 0.1 Mn O 2 (NCM811) and serious interfacial side reactions physical contact failures with sulfide electrolytes (SEs) are the main obstacles restricting ≥4.6 V high‐voltage cyclability all‐solid‐state lithium batteries (ASSLBs). To tackle this constraint, here, a modified NCM811 Li 3 PO 4 coating B/P co‐doping using inexpensive BPO raw materials via one‐step in situ synthesis process is presented. Phosphates have...
In this paper, we present a community-detection solution for massive-scale social networks using MapReduce, parallel programming framework. We use similarity metric to model the community probability, and is designed be parallelizable scalable in MapReduce More importantly, propose set of degree-based preprocessing postprocessing techniques named DEPOLD (DElayed Processing Large Degree nodes) that significantly improve both accuracy performance. With DEPOLD, delaying analysis 1% high-degree...
This paper explores the design and optimization implications for systems targeted at Big Data workloads. We confirm that these workloads differ from typically run on more traditional transactional data-warehousing in fundamental ways, and, therefore, a system optimized can be expected to other systems. Rather than only studying performance of representative computational kernels, focusing central-processing-unit performance, this studies as whole. identify three major phases typical...
Hot-stamping molding for ultra-high-strength steel have some similarities with traditional cold-stamping in the aspects of process and die design. But due to effect temperature variation blank, hot-stamping differences products design, material selection forming Some special defects, such as local thinning, cracking wrinkling, could appear these differences. In order obtain uniform phase structure get high-quality products, it is very important be able predict control blank consistence...
Lead-acid battery (LAB) has a huge world market in both energy storage and power supply. However, most LAB failures are caused by the serious corrosion of positive grids. To this, we propose an electrochemical prepassivation strategy to form compact interphase on lead-alloy grid surface composed lead oxides sulfate, exactly same as paste. The results show that resistance pre-passivated alloy is improved due inhibition vertical growth layer, providing feasible solution prolong service life LAB.
In permissioned blockchains, the bandwidth of consensus nodes is mainly consumed by transaction ordering and block distribution; hence, allocation nodes' makes a significant difference to system throughput. Previous research focuses on layer attempts optimize protocols improve throughput, which, however, neglects impact data distribution throughput transfers performance bottlenecks network layer. fact, overall blockchains co-determined production in This paper proposes novel flow framework...
