According to foreign media reports, the United States Department of Energy's US Lawrence Berkeley National Laboratory (Berkeley National Laboratory, the US Department of Energy's Lawrence Berkeley National Laboratory) designed a living polymer electrolyte binder (polyelectrolyte binder, PEB) , The key ion transport processes in Li-Si cells can be adjusted and the functional principle of operation can be demonstrated at the molecular level.
The new polymer binder doubled its capacitance compared to conventional lithium-sulfur batteries, even when discharged 100 times at high current densities.
Researchers at Molecular Foundry, a division of Berkeley Labs, have designed a polymer that ensures that sulfur is very close to the electrode, thanks to its ability to selectively bind sulfur molecules and thus offset The migration of the situation.
Experiments were carried out at Advanced Light Source in Berkeley Labs, and the Electrochemistry Discovery Lab, a unit of Argonne National Laboratory in the United States, confirmed the above inference. The synthesis, theory and properties of the new polymer make the adhesive an important part of the lithium-ion cell.
Researchers at the Joint Center for Energy Storage Research (JCESR) formed a research and development team with scientists at the Massachusetts Institute of Technology and the University of California, Berkeley (UC Berkeley) Funding is provided by JCESR.
