Vanderbilt researchers find iron pyrite quantum dots boost performance of sodium-ion and Li-ion batteries

Green Car Congress

nm, average) of iron pyrite (FeS 2 ) nanoparticles are advantageous to sustain reversible conversion reactions in sodium ion and lithium ion batteries. In this work we explore the sodium and lithium conversion of ultrafine FeS 2 nanoparticles, with a tight size distribution centered around ∼4.5

Researchers Develop Novel High-Performance Polymer Tin Sulfur Lithium Ion Battery

Green Car Congress

Lithium-sulfur cells are based on the electrochemical reaction: 16Li + S 8 8Li 2 S. The practical development of the lithiumsulfur battery has been hindered to date by a series of shortcomings. A major hurdle is the high solubility in the organic electrolyte of the polysulfides Li 2 S x (1?x?8) C+4.4Li + +4.4e -.

A closer look at graphite—its forms, functions and future in EV batteries

Charged EVs

Its physical structure allows it to store lithium ions. Some advanced designs use a small amount of silicon, which can store more energy. The anode side of the battery is where electrons or ions are stored during charge and moved to the cathode side during discharge. John DeMaio: Correct.
