P3-289Introduction of JST COI-NEXT Project "Advanced Battery Collaboration".Key Words: Rechargeable Batteries, Center for Advanced Battery CollaborationTo realize a safe and secure society where goods, services, and information reach every person and region using clean energy, it is necessary to develop inexpensive, large-scale stationary storage batteries to smooth out fluctuations in natural energy output and store surplus electricity, high-energy density and high-power density batteries to power mobile devices and robots, and safe and reliable batteries that can function on the human body, in buildings, and outdoors.⚫Creating various protocols to accelerate battery R & D⚫The protocol includes fundamental battery-related technologies such as characteristic simulation, materials databases, high-throughput automated experimental systems, computational science, and advanced measurement.ConclusionVision and Research OrganizationProtocol Target Area Map⚫At the 65th Battery Symposium to be held in Nagoya from November 18th to 20th, we will present 14 of our latest research topics in a special session.⚫The developed protocols are scheduled to be available to customers from April next year.Upcoming EventsIntroductionAt this center, we will establish scientific principles for understanding and controlling complex physicochemical phenomena and their hierarchical relationships at multiple scales, and design innovative batteries based on the underlying essential phenomena. We will also develop battery analysis and development design protocols for designing versatile storage batteries with various performance characteristics such as voltage, power, energy density, and lifespan.Theme underDiscussionCenter for Advanced Battery Collaboration, GREEN Masayuki NagamineContact E-mail：： NAGAMINE Masayuki@nims.go.jpElectrode 3D structure is obtained by plasma-FIB-SEM.Binarization or Ternaryization (Actine material, pore, and others)The binarization inevitably becomes far removed from the actual state.(due to SEM image quality)By brightness and contrastUsing machine learning in analysis software Tortuosity1.5~1.7Electrode performance simulation based on 3D structurePL : Kiyoshi KanamuraDischarge Curve @ 1C4.14.03.93.83.73.60.20.40.61.00.80-Converting 3D images obtainedwith FIB into mesh data-Calculations are performed bydividingthe volume elements into 1/25thsFuture work➢Improvement for meshing (especially for real 3D images)➢Consider the size required to reproduce the overall electrode characteristics➢Confirming the validity of the model by comparing with experimental resultsThe discharge curves are consistent with actual experimental results.This work was supported by JST COI-NEXT “Center for Advanced Battery Collaboration” Grant Number JPMJPF2016.
