A new integrated solar battery based on carbon nitride photoanodes
https://techxplore.com/news/2023-03-sol ... tride.html
by Ingrid Fadelli , Tech Xplore
In recent years, researchers have been trying to create increasingly efficient solar technologies and more sustainable battery designs. Among emerging sustainable energy solutions are solar batteries, systems that can store the energy collected by solar cells or photovoltaic (PV) systems.

A research group at the Max Planck Institute for Solid State Research, supervised by Prof. Bettina Lotsch, recently introduced a sustainable integrated solar battery design based on materials that abundant on Earth. Their design, presented in a paper published in Energy & Environmental Science, is based on a bi-functional carbon nitride (K-PHI) photoanode that can both absorb light and store electric charge.

"The solar battery research field is still young and as such very diverse in concepts and ideas, with different levels of integration," Andreas Gouder, one of the researchers who carried out the study, told Tech Xplore. "Integration means, that the two functionalities—light energy conversion and energy storage—are built into a single device. This can be done via different approaches, e.g., by adding a photoactive electrode into a battery, or—as done here—by using a bifunctional electrode material. However, integration may also affect charge transfer."

Across the Divide: Manufacturing Better Batteries
by Karyn Hede
March 30, 2023

Introduction:
(Pacific Northwest National Laboratory) Next generation lithium-based batteries provide a key component of the global strategy to meet decarbonization goals in transportation and beyond. We know lithium-based batteries provide high energy density. But there’s an elephant in the room. How will manufacturers not only meet greatly increased demand for more batteries for electric vehicles, but also produce advanced Li-ion and future batteries.

There is no shortage of ideas. New chemistries or discoveries are reported on nearly a daily basis. But then comes the real challenge: scaling laboratory materials and manufacturing processes to industry levels for commercial applications.

This scaling up is the elephant in the room, and it is faced head-on in a new Nature Energy review article led by battery researcher Jie Xiao and collaborators in academia and industry.

“We are asking the question, ‘how can we do research that is relevant to industry manufacturing?’” said Xiao. “We are accustomed to doing fundamental science. But how can the research community support manufacturing science? The questions and challenges are different. Industry doesn’t typically have the in-house resources to address these research questions raised during manufacturing.”

Cooking up millions of battery materials

Imagine the challenge of scaling up a recipe for a dozen cookies to one million cookies. The “dough” volume becomes much larger, and each batch has to be mixed and baked to an exact temperature and doneness each time, and then repeated exactly the same way day after day. That’s the challenge of scaling battery materials production from the lab to the factory floor.

Team finds major storage capacity in water-based batteries
https://techxplore.com/news/2023-04-tea ... based.html
by Raven Wuebker, Texas A&M University College of Engineering
Researchers at Texas A&M University have discovered a 1,000% difference in the storage capacity of metal-free, water-based battery electrodes.

These batteries are different from lithium-ion batteries that contain cobalt. The group's goal of researching metal-free batteries stems from having better control over the domestic supply chain since cobalt and lithium are outsourced. This safer chemistry would also prevent battery fires.

Chemical engineering professor Dr. Jodie Lutkenhaus and chemistry assistant professor Dr. Daniel Tabor has published their findings about lithium-free batteries in Nature Materials.

"There would be no battery fires anymore because it's water-based," Lutkenhaus said. "In the future, if materials shortages are projected, the price of lithium-ion batteries will go way up. If we have this alternative battery, we can turn to this chemistry, where the supply is much more stable because we can manufacture them here in the United States and materials to make them are here."

Lutkenhaus said aqueous batteries consist of a cathode, electrolyte and an anode. The cathodes and anodes are polymers that can store energy, and the electrolyte is water mixed with organic salts. The electrolyte is key to ion conduction and energy storage through its interactions with the electrode.

An energy breakthrough: Tech researchers create new type of fuel cell

by Kimberly Geiger, Michigan Technological University
https://techxplore.com/news/2023-04-ene ... -cell.html
Like batteries, fuel cells produce energy through an electrochemical process. Unlike batteries, they don't run down or require recharging. However, the potential advantages of fuel cells are offset by challenges that include cost, performance and durability.

Michigan Technological University researcher Yun Hang Hu and two graduate students, Hanrui Su and Wei Zhang, took on those challenges, changing the conventional path of a fuel cell by creating an interface between the electrolyte and melted carbonate as an ultrafast channel for oxygen ion transfer.

"This allowed us to invent an entirely new type of fuel cell, a carbonate-superstructured solid fuel cell (CSSFC)," said Hu, who holds the Charles and Carroll McArthur Endowed Chair Professorship of Materials Science and Engineering in the Department of Materials Science and Engineering at Michigan Tech.

Like other fuel cells, CSSFCs have a wide array of potential uses, from providing energy to operate fuel cell vehicles and home power generation to entire power stations. Because CSSFCs are fuel flexible, they offer higher durability and energy conversion efficiency at lower operating temperatures than other types of fuel cells.

Ultra-tough battery survives hammer blows and being run over by a car

29 March 2023

A flexible battery made from hydrogel can withstand being run over by a car, blows from a hammer and temperatures as low as −77°C (-106.6°F). It could potentially be used in phones or wearable electronics.

Most commercial batteries are solid and based on lithium, but these can be easily damaged in accidents and cope badly at very cold temperatures.

Nano-composite silicon anode promises EV range boost & 10-min charging
By C.C. Weiss
April 10, 2023

We've been covering the exploration and development of silicon battery anodes for well over a decade, but most of the breakthroughs have come at laboratory level. The past few years have seen the technology moving toward commercialization, and Silicon Valley battery materials company Sila announced this month that its Titan Silicon anode is now available. The new anode is already set to feature in the upcoming all-electric Mercedes-Benz G-Class and promises the potential for range increases of 20% and dramatic charging time decreases down to as low as 10 minutes.

Sila announced Titan Silicon availability last week, calling the technology a high-performance nano-composite silicon that's engineered to replace common graphite anodes on a mass scale. It estimates that the alternative anode tech could increase battery capacity enough to boost electric vehicle range by up to 20%, representing the potential addition of more than 100 miles (161 km) in current market range leaders like the 516-mile (830-km) 2023 Lucid Air Grand Touring. It believes future iterations could double those gains.
