Higher voltage and safer operation for Li-ion batteries

01 April, 2020

Researchers have improved the performance and safety of lithium-ion batteries, increasing not only the battery's voltage delivery but also its ability to suppress dangerous conditions.

Safety feature to stop lithium batteries catching on fire

19 March, 2020

Researchers made a tweak to the part of the battery called the separator, so that it slows down the flow of energy (and thus heat) that builds up inside the battery when it short circuits.

Organic molecules could enable more sustainable batteries

18 March, 2020

Organic electrode materials are considered to be extremely promising materials for sustainable batteries with high power capabilities.

Self-charging battery developed

03 March, 2020

Researchers have developed a new type of battery that combines negative capacitance and negative resistance within the same cell, allowing the cell to self-charge without losing energy.

Potassium-ion batteries could be made safer

03 February, 2020

Scientists have developed a nonflammable electrolyte for potassium and potassium-ion batteries, for applications in next-generation energy-storage systems beyond lithium technology.

Longer running lithium–air batteries

15 January, 2020

Researchers are improving the performance of lithium–air batteries, bringing us closer to electric cars that can use oxygen to run longer before they need to recharge.

Lithium-sulfur batteries developed Down Under

09 January, 2020

Australian researchers are on the brink of commercialising what is claimed to be the world's most efficient lithium-sulfur (Li-S) battery.

Partnership to develop next-gen sodium–sulfur batteries

19 November, 2019

NGK INSULATORS and BASF New Business have entered into a joint development agreement to develop the next generation of sodium‒sulfur batteries.

What causes dendrites and whiskers in lithium batteries?

12 November, 2019

Scientists have uncovered a root cause of the growth of the needle-like structures that plague lithium batteries, sometimes causing a short circuit, failure or even a fire.

Sandwich-structured electrode enhances lithium–sulfur batteries

23 October, 2019

The electrode was found to improve the practical energy density of a lithium–sulfur battery to three to five times higher than that of lithium-ion batteries.

Protein batteries for safe, sustainable power storage

10 October, 2019

By using synthetic polypeptides — which make up proteins — and other polymers, US researchers have taken the first steps towards constructing electrodes for sustainable organic batteries.

CSIRO and Piotrek partner on solid-state batteries

17 September, 2019

CSIRO and Piotrek have partnered to develop the next generation of solid polymer electrolytes (SPEs) for lithium batteries.

Maxim Integrated MAX17301 and MAX17311 one-cell fuel gauges

05 September, 2019

The MAX17301 and MAX17311 one-cell, pack-side ICs offer configurable settings for battery safety and allow fine-tuning of voltage and current thresholds based on various temperature zones.

The future of portable power

02 September, 2019 by Steven Keeping*

Is a big leap in Li-ion battery technology around the corner, or does the technology represent only a waypoint on the journey to a power source offering far more time between recharges?

Used car batteries converted into energy storage systems

26 August, 2019

The repurposed 2 kWh units could be used in developing countries or isolated communities, with enough energy to power a small shop, farm holding or multiple residential homes.
