New solid-electrolyte interphase may boost prospects for rechargeable Li-metal batteries

Green Car Congress

In a paper in Nature Materials , the Penn State team reports a molecular-level SEI design using a reactive polymer composite, which effectively suppresses electrolyte consumption in the formation and maintenance of the SEI. In this project, we used a polymer composite to create a much better SEI. V Li|LiNi 0.5 —Thomas E.

Polymer microcapsules with liquid carbonate cores and silicone shells offer a new approach to carbon capture

Green Car Congress

The team, led by scientists from Harvard University and Lawrence Livermore National Laboratory, employed a microfluidic assembly technique to produce microcapsules that contain liquid sorbents encased in highly permeable polymer shells. The polymer microcapsules are then heated to release absorbed CO 2 for subsequent collection.

Penn State team proposes cold sintering as way to improve solid-state battery production

Green Car Congress

In liquid batteries, you can take your two electrodes, and then add the electrolyte and as long as there’s something separating the two, usually a polymer, you have a battery. Cold sintering enables introducing the sintered solid electrolyte at very low temperatures. Sintered triphasic cathode.

Carnegie Mellon researchers develop semi-liquid lithium metal anode for use with solid electrolytes

Green Car Congress

Researchers from Carnegie Mellon University’s Mellon College of Science and College of Engineering have developed a semiliquid lithium metal-based anode (SLMA) that represents a new paradigm in battery design for solid electrolyte batteries. The SLMA consists of lithium microparticles evenly distributed in a dual-conductive polymer matrix.

TUAT team develops more efficient method to recover heavy oil using novel chemical flooding

Green Car Congress

Engineers may also make the water more alkaline by adding sodium hydroxide or sodium carbonate to help the oil flow better. This method is surfactant- and polymer-free. Generally, less than 10% of heavy oil may be produced from reservoirs by natural flow after drilling the well.
