IIT, Argonne team designs Li2O-based Li-air battery with solid electrolyte; four-electron reaction for higher energy density

Green Car Congress

The battery is rechargeable for 1000 cycles with a low polarization gap and can operate at high rates. By using a composite polymer electrolyte based on Li 10 GeP 2 S 12 nanoparticles embedded in a modified polyethylene oxide polymer matrix, we found that Li 2 O is the main product in a room temperature solid-state lithium-air battery. …

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

Green Car Congress

Rechargeable lithium metal batteries with increased energy density, performance, and safety may be possible with a newly-developed, solid-electrolyte interphase (SEI), according to Penn State researchers. In this project, we used a polymer composite to create a much better SEI. Credit: Donghai Wang,Penn State. V Li|LiNi 0.5

Georgia Tech team develops conversion-type iron-fluoride Li battery cathode with solid polymer electrolyte

Green Car Congress

Researchers at Georgia Tech have developed a promising new conversion-type cathode and electrolyte system that replaces expensive metals and traditional liquid electrolyte with lower cost transition metal fluorides and a solid polymer electrolyte. The Georgia Tech team sought to overcome those obstacles by using the solid polymer electrolyte.

GM researchers demonstrate hierarchical electrode architectures for high energy lithium-chalcogen rechargeable batteries

Green Car Congress

A corresponding chalcogen cathode structure, which is composed of a chalcogen element (S or Se), a conductive framework, and a polymer binder, is well-accepted for most studies. Therefore multi-functional frameworks were adopted to provide reactive sites, electronic conducting channels, and polysulfide constraining reservoirs. 2018.07.015.
