Researchers identify new class of non-flammable electrolytes for Li-ion batteries

Green Car Congress

Balsara at UC Berkeley, have identified a new class of nonflammable electrolytes based on functionalized perfluoropolyethers (PFPEs) for lithium-ion batteries. In addition to being nonflammable, PFPE exhibits very interesting properties such as its ion transport. That makes this electrolyte stand apart from previous discoveries.

Goodenough perspective on Li-ion batteries; in transportation, PHEVs for the near-term, longer term requires new electrochemical strategies

Green Car Congress

John Goodenough at the University of Texas at Austin and colleague Kyu-Sung Park have written a perspective paper on Li-ion batteries (LIBs), published in the Journal of the American Chemical Society. This shift of emphasis leads inevitably to the electrolyte, catalysts, and organic multiple-electron redox centers.

Li-ion sulfur polymer battery shows high energy density as well as safety

Green Car Congress

A team from the University of Rome Sapienza has developed a rechargeable lithium-ion polymer battery based on the combination of a high capacity sulfur-carbon cathode, nanostructured Li x Sn-C anode and polysulfide-added PEO-based gel membrane. Moreover, the addition of a dissolved polysulfide (i.e.

Univ. of Texas researchers propose lithium- or sodium-water batteries as next generation of high-capacity battery technology; applicable for EVs and grid storage

Green Car Congress

Example of a lithium-water rechargeable battery. Researchers at the University of Texas, including Dr. John Goodenough, are proposing a strategy for high-capacity next-generation alkali (lithium or sodium)-ion batteries using water-soluble redox couples as the cathode. A typical Li-air battery discharges at 2.5-2.7
