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

Fraunhofer develops new dry-coating process for battery electrodes

Green Car Congress

This coating contains the active components that are responsible for storing energy. It could equally be used on lithium-ion cells as on lithium-sulfur or sodium-ion cells. Electrodes normally consist of a metal foil with a thin coating. We are even looking at solid-state batteries.

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. Click to enlarge.

Can Flow Batteries Finally Beat Lithium?

Cars That Think

Monique closes her EV’s fueling port and heads onto the highway with enough stored energy to drive 640 kilometers (400 miles). The scientists found the nanofluids could be used in a system with an energy-storing potential approaching that of a lithium-ion battery and with the pumpable recharging of a flow battery.

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.
