Argonne boosts silicon anode performance in lithium-ion batteries with new electrolyte mixture

Fri, 10/11/2019 - 10:44 -- Paul Crompton

Researchers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory have developed an electrolyte mixture and additive they claim boosts the energy density of next generation lithium-ion batteries by up to 50%. 

To develop its electrolyte additive the scientists added small amount of a second salt containing doubly or triply charged metal cations magnesium (Mg2+), calcium (Ca2+), zinc (Zn2+), or aluminium (Al3+). 

Image by Argonne National Laboratory: shows charging results in doubly or triply charged metal cations, such as Mg2+ (orange spheres), along with singly charged lithium ions (green spheres) being co-inserted from the electrolyte into the silicon (blue spheres) anode material. This process stabilises the anode, enabling long term cycling of lithium-ion batteries.

Scientists double output of flow batteries by revisiting old research

Scientists at the University of Colorado Boulder have devised redox flow battery electrolyte that could double the performance capabilities of traditional variants of the technology.

The team used chromium and organic binding agents to achieve ‘exceptional voltage and high efficiencies’ of 100% current efficiency and an 80% round-trip energy efficiency. The results were published in the journal Joule.

Sensor targets acid stratification

A new ‘sensor’ developed to combat acid stratification has been unveiled by Johnson Controls. 

The sensor, presented at last month’s international conference on lead-acid batteries (LABAT17) in Sofia, Bulgaria, comprises an array of several electrochemical mini-cell sensors that simultaneously and continuously measure electrolyte density in different parts of battery cells.

Future of lead-acid lays beyond carbon additives

Chinese battery maker Narada Power Source has boosted the performance of an advanced lead-acid battery by reducing the electrolyte and enhancing the partial state-of-charge window.

The company also tweaked the re-charge algorithms to allow its advanced deep-cycling valve regulated lead-acid (VRLA) battery to achieve more than 26,000 power-assisted cycles.
