Slides (already) uploaded to https://hackingmaterials.lbl.gov
2. The promise of data-driven research –
more successes, fewer failures
Conventional design
many ideas are tested and most result in failure
Data-driven design
ideas are tested (or even hypothesized) by a
computer prior to testing, leading to higher success
rates in experiment
3. Outline of talk

workflow management software for
high-throughput computing
materials science analysis code:
make, transform and analyze crystals,
phase diagrams and more
& more … MP team members also contribue to
several other non-MP codes, e.g. matminer for
machine learning featurization

Schrodinger: Many of our customers are active users of
the Materials Project and use MP databases for
their projects. Enabling direct access to MP databases
from within Schrödinger software is a powerful addition
that will be appreciated by our users.
Toyota: “Materials Project
is a wonderful project.
Please accept my
appreciation to you to
release it free and easy to

High-throughput computational screening led
to the identification of several novel Li-ion
battery cathodes.
The data formed the basis of the original
Materials Project release.
14. Apart from identifying materials, it was used to create
“design maps” and better understand statistical trends

22. Conclusion and opportunities
• The Materials Project is used by a large community of users for functional
materials design and research
• Many potential applications to energy storage:
• Electrode materials (anode / cathode)
• Solid ion conductors
• Coatings
• New projects and capabilities are bridging the gap between virtual design and
physical realization – i.e., theory to synthesis
