"World's first working thermal battery" promises cheap, eco-friendly, grid-scalable energy storage

Loz Blain March 31, 2019

A South Australia-based startup says it's built a thermal energy storage device with a lifetime of at least 20 years that can store six times more energy than lithium-ion batteries per volume, for 60-80 percent of the price.

Hybrid cathodes improve energy density of lithium-sulfur batteries

Michael Irving March 25, 2019

Engineers have developed a new type of hybrid cathode for a lithium-sulfur battery that seems to boast better energy density than existing versions of both lithium-ion and lithium-sulfur batteries.

Energizer phone's beefy battery lasts "weeks" on a charge

Michael Irving February 26, 2019

At Mobile World Congress this week, Energizer unveiled the P18K Pop, which is basically more battery than phone. Packing a ridiculous 18,000 mAh capacity, it apparently lasts weeks on a charge – but on the flip side, it brings new meaning to the old phrase “brick phone.”

Carbon capture system turns CO2 into electricity and hydrogen fuel

Michael Irving January 21, 2019

Inspired by the ocean’s role as a natural carbon sink, researchers at Ulsan National Institute of Science and Technology (UNIST) and Georgia Tech have developed a new system that absorbs CO2 and produces electricity and useable hydrogen fuel.

The most innovative battery designs of the year

Nick Lavars December 28, 2018

How we store that energy is a constant work in progress, and while scientists are making important but incremental advances with inventive new materials, others are out to entirely reinvent what we think of as a battery. Here are five of the most innovative examples from 2018.

Fluoride-based battery challenges lithium for stability and stamina

Michael Irving December 6, 2018

A new study shows how fluoride might be put to work in better batteries. Researchers at Caltech, JPL, Lawrence Berkeley National Lab and the Honda Research Institute have developed fluoride-based batteries that could potentially last much longer than existing lithium-ion-based devices.

MIT's conceptual "sun-in-a-box" energy storage system plugs into molten silicon

Michael Irving December 6, 2018

Lithium-ion batteries aren't necessarily the best choice for grid-scale energy storage. Researchers at MIT have outlined a new system they call a “sun in a box,” which stores energy as heat in molten silicon and harvests it by tapping into the bright light it emits.

Energy Vault to build grid-level, gravity-fed battery from a tower of concrete blocks

Michael Irving November 8, 2018

With a focus on storing energy from intermittent renewable sources such as wind and solar, Swiss company Energy Vault has just launched an innovative new system that stores potential energy in a huge tower of concrete blocks, which can be “dropped” by a crane to harvest the kinetic energy.

Nanotube film drowns out battery-killing lithium tentacles

Nick Lavars November 4, 2018

New research out of Rice University describes yet another promising possible solution to the problem of dendrite formation in lithium-based batteries, working a thin film of carbon nanotubes into the design as as way of drowning them out.

Can carbon fiber car panels double as energy storage materials?

Nick Lavars October 18, 2018

Carbon fiber as we know it is one of the most impressive materials in our toolkit, but could it also play a role in energy storage? One team of scientists has been exploring the possibilities, raising some interesting possibilities for weight-saving vehicle design.
