WPI-led team develops dry-print process to make better, cheaper electrodes for Li-ion batteries

Green Car Congress

A team led by Worcester Polytechnic Institute (WPI) researcher Yan Wang has developed a solvent-free process to manufacture lithium-ion battery electrodes that are greener, cheaper, and charge faster than electrodes currently on the market. WPI has filed a patent application on the manufacturing technology developed by Wang’s team.

KIT coordinating EPIC project; accelerated drying of electrodes for Li-ion batteries

Green Car Congress

The new EPIC project coordinated by Karlsruhe Institute of Technology (KIT) is aimed at accelerating the drying of high-quality electrodes for lithium-ion batteries, increasing the energy efficiency of this process and, hence, reducing the cost of production. EPIC is funded by the Federal Ministry of Research with €3 million.

Researchers in Belgium develop new class of solid composite electrolytes for Li-ion batteries: Eutectogels

Green Car Congress

Researchers at Hasselt University in Belgium are proposing a new class of solid composite electrolytes (SCEs) for Li-ion batteries: deep eutectic solvent (DES)–silica composites. Structural schematic of a Li/LFP cell with the ETG as electrolyte. V versus Li, and unable to stop the growth of lithium dendrites.

thyssenkrupp and partners launch collaborative project EffiForm to lower Li-ion battery cost through improved formation cycling

Green Car Congress

The high cost of battery cells continues to be a major stumbling block to improving the cost-efficiency and popularity of e-mobility. Roughly a third of battery production costs are currently accounted for by the final step in the manufacturing process—formation cycling. —Wood et al. 2014.11.019.

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. More recently, at the University of Texas, Austin, Dr. Goodenough patented a new class of iron phosphate materials.

KIT develops new coating process to produce Li-ion electrodes at record speed

Green Car Congress

With a new coating process, researchers of Karlsruhe Institute of Technology (KIT) have produced electrodes for lithium-ion batteries at record speed. At the same time, the new process improves the quality of electrodes and reduces production costs. Even smallest production errors make battery cells unusable.

Stanford, CMU, MIT team reviews challenges to practical implementation of solid-state Li-ion batteries

Green Car Congress

Solid-state lithium-ion batteries, with higher volumetric energy densities than currently available lithium-ion batteries, offer a number of conceptual advantages including improved packaging efficiency; improved safety; and long cycle life. However, there remain a number of unresolved issues precluding commercialization at this point.
