MIT engineers create 2D polymer that self-assembles into sheets

Green Car Congress

Using a novel polymerization process, MIT chemical engineers have created a new two-dimensional polymer that self-assembles into sheets, unlike all other polymers which form one-dimensional chains. Until now, scientists had believed it was impossible to induce polymers to form 2D sheets.

MIT Sequential Decomposition Synthesis process produces thin solid-state electrolytes without sintering

Green Car Congress

A team from MIT has developed a new approach to fabricating oxide-based solid-state electrolytes that are comparable in thickness to the polymer separators found in current Li-ion batteries without sintering: sequential decomposition synthesis (SDS). Overview of sequential decomposition synthesis (SDS) processing.

MIT researchers propose mechanism for overcoming bottleneck in electroreduction of CO2

Green Car Congress

Researchers at MIT have identified , quantified, and modeled a major reason for the poor performance of electroreduction processes to convert CO 2 to fuel or other useful chemicals. This unwanted reaction uses up energy and greatly reduces the overall efficiency of the conversion process, the researchers found. —Soto et al.

Directly-cooled lighter-weight EV motor made with polymer housing

Green Car Congress

Researchers at the Fraunhofer Institute for Chemical Technology ICT are working together with the Karlsruhe Institute of Technology KIT to develop a new cooling concept that will enable polymers to be used as EV electric motor housing materials, thereby reducing the weight of the motor and thus, the EV itself.

MIT team develops data-driven safety envelope for lithium-ion batteries for EVs

Green Car Congress

Researchers at MIT, with a colleague from Tsinghua University, have developed a safety envelope for Li-ion batteries in electric vehicles by using a high accuracy finite element model of a pouch cell to produce more than 2,500 simulations and subsequently analyzing the data with Machine Learning (ML) algorithms. —Li et al.

MIT proof-of-concept demo of ionic wind propulsion for aircraft

Green Car Congress

MIT researchers have demonstrated that an aircraft with a 5-meter wingspan can sustain steady-level flight using ionic-wind propulsion. The MIT team’s final design resembles a large, lightweight glider. The fuselage of the plane holds a stack of lithium-polymer batteries. —Xu et al. Sped up 2x. Credit: Steven Barrett.
