Materials and assembly for Lithium-ion chemistry has been a practical and intriguing field to study. The development of materials for energy applications requires mastery of material chemistry, as well as in-depth knowledge of system requirements, and my laboratory combines synthetic chemistry, composite engineering and electrochemistry to solve interdisciplinary problems. My lab’s current research in battery and energy storage includes silicon materials and electrode binders for advanced lithium-ion battery, lithium-sulfur battery, solid-state battery, and electrode interfaces. One focus of our research is to synthesize new materials and develop new assembly approaches to improve the energy density, increase life, and lower the cost of lithium-ion batteries for vehicular applications. My lab also performs research in hydrogen generation, plastic recycling, and advanced manufacturing.

2022 R&D 100 Award: Quick-Release™ Binder for Recyclable Batteries - August 22nd 2022
The Quick-ReleaseTM Binder solves a major challenge of materials recovery for Li-ion battery direct recycling. The current recycling process, which includes shredding, grinding, and pyrolysis of the materials, is highly energy intensive and has a large environmental footprint. The Quick-Release Binder eliminates these processes–as well as the production of toxic gases–by using water processes for manufacturing and recycling. All the battery components simply dissociate in pH adjusted water and are easily recovered and reprocessed. As a low-cost, nontoxic, and effective product, the Quick-Release binder represents a major technological advancement, and it facilitates the use and expansion of green energy storage, supporting international efforts to create a circular economy.
2015 R&D 100 Award - November 17th 2015
A team led by Gao Liu of Lawrence Berkeley National Laboratory’s (Berkeley Lab’s) Energy Storage & Distributed Resources Division has won a 2015 R&D 100 award for developing a high-capacity anode for rechargeable batteries. Berkeley Lab’s Hui Zhao also participated in the development, as did Zeptor co-founder and Chief Technology Officer, Chuck Consorte.
The material and process developments from Berkeley Lab and Zeptor finally made it possible to transition from low-capacity graphite anodes to economical, high-capacity silicon anodes. The technology is already moving toward commercialization; Zeptor is using it to produce a high-capacity rechargeable battery that can double the lifespan of a state-of-the-art lithium-ion battery, increasing capacity by 40 percent. Pilot tests show a higher capacity, a longer lifespan, improved safety, and lower costs than state-of-the-art batteries.
In addition, the Berkeley Lab and Zeptor team is also working with consumer electronics and electric vehicle manufacturers to improve lithium-ion battery performance in those sectors, and the end users are planning to use the resulting high-energy-density battery in the next generation of products.

2013 R&D 100 - July 08th 2013
Gao Liu and his team developed a technology to boost the power storage capacity of lithium-ion batteries. The new material, for use in rechargeable batteries, can boost power storage capacity by 30 percent, a dramatic improvement in a field marked by little progress for more than a decade. It is called Conducting Polymer Binder, literally a kind of flexible plastic glue that holds electrode materials together while facilitating the shuttling of electrons and positively charged lithium ions.
Presented by R&D Magazine, the R&D 100 Awards recognize the year’s top 100 technology products from industry, academia, and government-sponsored research, ranging from chemistry to materials to biomedical breakthroughs.
