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,

Novel Li-metal electrode design could lead to more powerful solid-state batteries

Green Car Congress

Researchers at MIT and their colleagues are proposing a new design for electrodes that, based on the long-sought goal of using pure lithium metal as the anode, could lead to longer-lived batteries with higher energy densities. The metal then shrinks again during discharge, as the battery is used. —Ju Li.
