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

Green Car Congress

Researchers at the Illinois Institute of Technology (IIT) and US Department of Energy’s (DOE) Argonne National Laboratory have developed a lithium-air battery with a solid electrolyte. The battery is rechargeable for 1000 cycles with a low polarization gap and can operate at high rates. Image by Argonne National Laboratory.)

Polymer Coated EV Batteries Offers Increased Range And Battery Life

Get Electric Vehicle

The Berkeley Lab has created a conductive polymer coating known as HOS-PFM that could be used for coating lithium-ion batteries for electric vehicles (EVs). This could increase the range and life of EV batteries. Now we know the recent developments in the coating of EV batteries, let us look into the basics.

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.

Stanford/SLAC team redesign current collectors to make them lighter, safer and about 20% more efficient

Green Car Congress

Scientists at Stanford and SLAC redesigned current collectors to make lithium-ion batteries lighter, safer and more efficient. They replaced the all-copper conductor, middle, with a layer of lightweight polymer coated in ultrathin copper (top right), and embedded fire retardant in the polymer layer to quench flames (bottom right).

Chalmers team develops structural battery that performs 10x better than previous versions

Green Car Congress

Researchers from Chalmers University of Technology, in collaboration with KTH Royal Institute of Technology in Stockholm, have produced a structural battery that performs ten times better than all previous versions. The carbon fiber acts as a host for the lithium and thus stores the energy. 1 , an elastic modulus of 25?GPa,

Self-healing polymer wrapper enables longer cycle life in silicon anodes for Li-ion batteries

Green Car Congress

Top: The stress of repeated swelling and shrinking shatters a conventional silicon electrode and its polymer binding. Bottom: An electrode coated with stretchy, self-healing polymer remains intact. (C. We want to incorporate this feature into lithium-ion batteries so they will have a long lifetime as well. Wang et al.,

Simple process transforms PET plastic into a nanomaterial for supercapacitors

Green Car Congress

Then, using an electrospinning process, they fabricated microscopic fibers from the polymer and carbonized the plastic threads in a furnace. Although they don’t store as much energy as lithium-ion batteries, these supercapacitors can charge much faster—a good option for many applications.
