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 nanometers in size.

Fraunhofer develops new dry-coating process for battery electrodes

Green Car Congress

Conventional processes for manufacturing battery electrodes involve mostly toxic solvents and require a lot of space and energy. DRYtraec thus is a promising solution developed by an interdisciplinary research team at Fraunhofer IWS in Dresden that focuses on the production of the battery electrodes.

Sulfur–TiO2 yolk-shell cathode for Li-sulfur battery shows best long-cycle performance so far

Green Car Congress

Researchers at Stanford University and SLAC led by Stanford associate professor Yi Cui have used a sulfur–TiO 2 yolk–shell design for a cathode material for a lithium-sulfur battery that achieved an initial specific capacity of 1,030?mAh?g Click to enlarge. C and Coulombic efficiency of 98.4% over 1,000 cycles.

Can Flow Batteries Finally Beat Lithium?

Cars That Think

As she drives her electric vehicle to her mother’s house, Monique’s battery gauge indicates that it’s time to reenergize. Monique closes her EV’s fueling port and heads onto the highway with enough stored energy to drive 640 kilometers (400 miles). This battery, though, uses a completely new kind of fluid, called a nanoelectrofuel.

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

Charged EVs

Its physical structure allows it to store lithium ions. There are three main forms of graphite: spherical graphite is used in non-EV battery applications, whereas EV batteries use a blend of coated spherical graphite and synthetic graphite. Some advanced designs use a small amount of silicon, which can store more energy.
