The quest for better batteries is an ongoing trend, and now the researchers from the Department of Energy’s Oak Ridge National Laboratory (ORNL) have yet another development to add.

During their research, the scientists found exceptional properties in a garnet material. They now believe that this could lead to the development of higher-energy battery designs.

This from ORNL:

The ORNL-led team used scanning transmission electron microscopy to take an atomic-level look at a cubic garnet material called LLZO. The researchers found the material to be highly stable in a range of aqueous environments, making the compound a promising component in new battery configurations.

While most researcher tend to use a pure lithium anode to improve a battery’s energy density, the ORNL scientists believe the LLZO would be an ideal separator material.

“Many novel batteries adopt these two features [lithium anode and aqueous electrolyte], but if you integrate both into a single battery, a problem arises because the water is very reactive when in direct contact with lithium metal,” said ORNL postdoctoral associate Cheng Ma, first author on the team’s study published in Angewandte Chemie. “The reaction is very violent, which is why you need a protective layer around the lithium.”

With developments such as these, which lead to higher-energy batteries – we begin to improve electrified transportation and electric grid energy storage applications. Due to the importance of higher-energy batteries, researchers tend to explore battery designs beyond the limits of lithium-ion technologies.

Researchers at Nanyang Technological University have developed ultra-fast charging batteries that last 20 years.

If you’re tired of spending more time charging your phone than actually using it, a team of researchers out of Singapore have some good news for you. The group from Nanyang Technological University (NTU) have developed an ultra-fast charging battery – so fast that it can be recharged up to 70 percent in only two minutes.

When comparing this new discovery to the already existing lithium-ion batteries, the new generation has a lifespan of over 20 years – approximately 10 times more than the current lithium-ion battery. Further, each of the existing li-ion’s cycles takes two to four hours to charge, which is significantly more than the new generation’s two minute charge time.

The development will be of particular benefit to the industry of electric vehicles, where people are often put off by the long recharge times and limited battery life. The researchers at NTU believe that drivers of electric vehicles could save tens of thousands on battery replacement costs and will be able to charge their cars in just ten minutes, all in thanks to the new ultra-fast charging battery.

This from NTU:

In the new NTU-developed battery, the traditional graphite used for the anode (negative pole) in lithium-ion batteries is replaced with a new gel material made from titanium dioxide. Titanium dioxide is an abundant, cheap and safe material found in soil. It is commonly used as a food additive or in sunscreen lotions to absorb harmful ultraviolet rays. Naturally found in spherical shape, the NTU team has found a way to transform the titanium dioxide into tiny nanotubes, which is a thousand times thinner than the diameter of a human hair. This speeds up the chemical reactions taking place in the new battery, allowing for super-fast charging.

Sadoway’s research seeks to establish the scientific underpinnings for technologies that make efficient use of energy and natural resources in an environmentally sound matter.

Donald R. Sadoway – a prominent member of The Electrochemical Society and electrochemist at the Massachusetts Institute of Technology in Cambridge – has led a team of researchers at MIT to improve a proposed liquid battery system that could help make sources of renewable energy more viable and prove to be a competitor for conventional power plants.

This from MIT News:

Sadoway, the John F. Elliott Professor of Materials Chemistry, says the new formula allows the battery to work at a temperature more than 200 degrees Celsius lower than the previous formulation. In addition to the lower operating temperature, which should simplify the battery’s design and extend its working life, the new formulation will be less expensive to make, he says.

Recently some researchers move to Mg batteries. Pellion Tech in its white paper claims double energy density both in volumetric and gravimetric for Mg batteries.

I am confused since it seems that the discharge voltage should be at least 3V and no cell have been reported working experimentally at such potential yet (Maybe I did not find).

Moreover, the safety issues will not come for Mg batteries with magnesium anodes? and for Mg-ion batteries, the energy density would be competitive with current Li-ion batteries?

Does the main opportunity for Mg batteries lie in their cathodes same as Lithium batteries?
