Through a combination of computer modeling work at CMU and experimental tests at MIT, the researchers hope to show that halide-enriched battery cells can electrochemically form a lithium-halide-based solid electrolyte to protect lithium metal electrodes. Electrolytes are the barrier through which the active elements of a battery, for example, lithium ions, cycle back and forth between a positive electrode and a negative electrode.
The researchers hope the combination of a lithium-halide solid electrolyte with lithium metal negative electrodes will slow or prevent the buildup of icicle-like metal filaments, known as “dendrites,” that build up on the metal electrode. This unwanted buildup eventually leads to battery failure. The researchers believe the iodine-enhanced electrolyte may offer a “self-healing” process that protects the electrode from sprouting these dendrites. Under this project, they will develop prototype batteries, whose performance can be compared to similar lithium batteries without halide additives.
MIT postdoc Linsen Li and undergraduate senior Harry Thaman are working on the MIT portion of the project.
