Li-ion and Li metal batteries are widely used for portable devices due to their high gravimetric and volumetric energy densities and cyclability. However, overcharging and extreme discharging of the battery can lead to overheating and thermal runaway, while improper use can lead to fires and explosions. The volatility and flammability of the organic solvents (ethylene carbonate/dimethyl carbonate) used as electrolytes are the major sources of these thermal stability issues. Therefore, an alternative to flammable electrolytes, room temperature ionic liquids (RTILs) electrolyte chemistry is investigated due to its high thermal and electrochemical stability. Here, the fundamental understanding of developing high temperature Liion battery materials is evaluated using electrochemistry and depth-dependent the X-ray spectroscopy techniques.

Extreme fast charging (XFC) of lithium-ion batteries (LIBs) in 10 minutes is one of the main goals of the US Advanced Battery Consortium for low-cost, fast-charged electric vehicles by 2023. However, existing LIBs cannot achieve these XFC goals without significant capacity fade over cycling due to complex XFC degradation modes. One of the key XFC failure mechanisms is dead Li plating on the graphite anode. While numerous methods have detected Li plating, they lack three-dimensional non-invasive visualization of dead Li on graphite anodes in full cells during battery cycling. Herein, we demonstrate the viability of high-resolution (spatial resolution: 10–15 μm) neutron micro-computed tomography (μCT) for in-situ characterization of dead Li on graphite anodes (thickness: ~130 μm) in full cells containing NMC cathode, that were cycled at 1C and 6C.

This project will address the critical bottleneck in electrochemical redox processes (i.e., decreasing cost and improving efficiency) for wastewater treatment and resource recovery by developing cost-effective and selective electrode materials that can treat or valorize ROC for safe discharge or reuse. The overarching goal is to develop an electrochemical prototype to degrade a wide range of organic contaminants, minimize electrodes’ fouling and scaling, and recover valuable resources (e.g., metals and salts), contributing to achieving “pipe parity” and “circular economy” using small-scale and modular electrochemical water treatment systems.

In this installment of the “Looking at Patent Law” series, we illustrate a high-level perspective of the impact of electrochemical science and engineering on innovation and technology development, as evidenced by inclusion within the patent literature. We searched the USPTO patent data base for the past thirty-one years using commercially available software. The search was limited to U.S. patents and included the Boolean search string was “electrochem* OR electroly*” for U.S. patents issued within the date range of 01/01/1991 to 12/31/2021. Over the past ten years “electrochemical” patents represent nearly 5% of “all” issued patents. The top assignees of the “electrochemical” patents attend and/or present at biannual ECS meetings and publish in ECS journals. Notable top inventors of “electrochemical” patents include: 1) Dr. Shumpei Yamazaki with over 800 patents, 2) Dr. Adam Heller, the inventor of the electrochemical-based glucose monitor, and 3) Dr. Esther Takeuchi, inventor of the implantable cardiac defibrillator.

Reactive oxygen and nitrogen species (ROS/RNS) are known to play an essential role in cell signaling, disease development and progression. The production of ROS/RNS in living cells can be induced by diacylglycerol-lactone (DAG-lactone) through activation of protein kinase C, an important therapeutic target for cancer and other diseases. In a previous report, nano-electrochemistry was performed to evaluate the production of ROS/RNS inside a human breast cell (MCF-10A) treated with DAG-lactone. Simultaneously, the formation of large intracellular vacuoles was observed using a microscope. These results suggest a possibility that the ROS/RNS were stored in the intracellular vacuoles. The experiments carried out during this summer were aimed to elucidate the relationship between the intracellular production of vesicles and ROS/RNS.
