Our perspective, The rise of high-entropy battery materials, is published in Nature Communications.

By blending diverse elements to increase configurational entropy, one can create high-entropy materials with interesting and beneficial properties. We share our perspectives on how high-entropy materials hold new possibilities for electrochemical energy storage. We elucidate the principles behind high-entropy battery materials and point out the challenges that must be addressed to unlock their utmost potential.

Our paper, Selective formation of metastable polymorphs in solid-state synthesis, is published in Science Advances.

We present a theoretical model designed to predict and guide the initial formation of polymorphs in solid-state reactions. Our findings suggest that reaction energy, an often overlooked factor, plays a significant role in determining which polymorph emerges first, affecting how surface energy facilitates the nucleation of metastable phases. By selecting specific precursors, it's possible to influence the reaction energy, thereby enabling the formation of a desired metastable polymorph.

Our paper, An autonomous laboratory for the accelerated synthesis of novel materials, is published in Nature.

After three and a half years of building the hardware and software, we introduce the A-Lab, an autonomous laboratory for the solid-state synthesis of inorganic powders. This platform uses computations, historical data from the literature, machine learning (ML) and active learning to plan and interpret the outcomes of experiments performed using robotics.

Our paper, Autonomous and dynamic precursor selection for solid-state materials synthesis, is published in Nature Communications.

We developed an algorithm, ARROWS3, to adaptively optimize the selection of precursors for solid-state reactions. This approach leverages thermochemical data and machine learning to learn from experimental outcomes, significantly reducing the number of experiments needed.

A-Lab featured in, Science, and Popular Science

The A-Lab is an AI-driven robotic lab for materials synthesis and characterization in the solid state. Dr. Zeng has led a team of students and postdocs at LBNL and UC Berkeley since 2020 in building up the lab, its software, and the AI algorithms that help the robots to make better decisions.

In February 2023, A-Lab began its journey of making and discovering novel materials.

Science magazine published an article featuring the completion of the A-Lab. 

Popular Science featured the A-Lab and compared it to Tony Stark's lab.

Check out these videos of robotic arms doing experiments in the A-Lab!

Shown left: Conventional solid “ordered” electrolyte made of just one type of metal (blue spheres). The movement of lithium ions (yellow sphere) is slow and limited, thus hampering ion conductivity and battery performance. (Gray spheres represent oxygen.) Shown right: Ions move significantly faster through “disordered” solid electrolyte: Mixing different types of metals (blue, teal, and navy spheres) creates new pathways – much like the addition of expressways on a congested highway – through which lithium ions can move quickly through the electrolyte.
