Finnish sustainable material developers have opened a mill that turns powdered tree macromolecules into energy   

By Shannon McDonagh 

A material found in the wood of our plants is being trialled as a way to produce sustainable battery power.

Finnish designers Stora Enso have built a new production facility costing €10 million that will create renewable bio-based carbon by turning trees into batteries. This will be achieved by the use of a wood-based material called lignin.

The plant is based beside the company’s Sunila Mill in Kotka, southern Finland, which employs over 150 people and specialises in producing softwood pulp, and biofuels like tall oil and turpentine.

The company is responsible for developing a number of wood and biomaterial-based solutions for everyday problems that require eco-friendly solutions. Their innovative product offerings range from mouldable woods to formed fiber food packaging.

The two agreed to advance safe deployment and use of second-life battery energy storage systems.

Underwriters Laboratories, a U.S. standards development organization, and Koren car manufacturer Hyundai Motor Co. signed a memorandum of understanding to help further the safe deployment and use of second-life battery energy storage systems (SLBESS). 

The two said they will collaborate on SLBESS initiatives, including safety testing and assessment, a North America product demonstration project, and evaluation process development. They said they intend to use their worldwide presence to further SLBESS market adoption.

Second-life batteries often consist of electric vehicle batteries that no longer meet the requirements of automotive applications, but are still worthwhile additions as grid-connected energy storage devices.

We may be on the brink of a new paradigm for nuclear power, a group of nuclear specialists suggested recently in The Bridge, the journal of the National Academy of Engineering. Much as large, expensive, and centralized computers gave way to the widely distributed PCs of today, a new generation of relatively tiny and inexpensive factory-built reactors, designed for autonomous plug-and-play operation similar to plugging in an oversized battery, is on the horizon, they say.

Lithium-metal batteries hold far more energy and charge in a fraction of the time compared to those used in smartphones and electric cars

By Anthony Cuthbertson

Researchers have demonstrated a solution to a 40-year problem regarding the creation of a “holy grail” battery that could radically transform the electric car industry.

The breakthrough involves harnessing the power of lithium-metal batteries, which are capable of holding substantially more energy and charge in a fraction of the time compared to lithium-ion batteries that are currently used in everything from smartphones to Tesla vehicles.

Until now, scientists have been unable to create a lithium-metal battery stable enough to be used in commercial applications.

The development, made by a team at Harvard University’s School of Engineering and Applied Science (SEAS), allows this next-generation batter to be charged and discharge at least 10,000 times, which would increase the lifetime of electric vehicles to that of of their gasoline counterparts – while simultaneously increasing their range and reducing their charge time.

“A lithium-metal battery is considered the holy grail for battery chemistry because of its high capacity and energy density,” said Xin Li, an associate professor at SEAS.

It could revolutionize electric vehicles and aircraft.

• Scientists have made a massless structural battery 10 times better than before.
• The battery cell performs well in structural and energy tests, with planned further improvements.
• Structural batteries reduce weight and could revolutionize electric cars and planes.

In groundbreaking new research, scientists have made a structural battery 10 times better than in any previous experiment. 

What’s a structural battery, and why is it such a big deal? The term refers to an energy storage device that can also bear weight as part of a structure—like if the studs in your home were all batteries, or if an electric fence also held up a wall.

In the new paper, researchers from Chalmers University of Technology and KTH Royal Institute of Technology in Sweden reveal how their “massless” structural battery works.RELATED STORYIs the World Ready for the EV Battery Boom?

The main use case is for electric cars, where a literally massive amount of batteries take up a ton of room and don’t contribute to the actual structure of the car. In fact, these cars must be specially designed to carry the mass of the batteries. But what if the frame of the car could hold energy? “Due to their multifunctionality, structural battery composites are often referred to as ‘massless energy storage’ and have the potential to revolutionize the future design of electric vehicles and devices,” the researchers explain.

The analysts assessed the current state of reuse and recycling of large-format lithium-ion batteries used in EVs and battery energy storage and found there is plenty of room for improvement.

Recycling lithium-ion batteries could create a new market for U.S. companies, an NREL report said.

Researchers at the National Renewable Energy Laboratory (NREL) released a report detailing the technological, market, and regulatory hurdles to creating a circular economy for lithium-ion batteries.

The battery technology is increasingly in demand for energy storage and use in electric vehicles (EVs). But its current lifecycle is almost entirely one-way, from manufacture to consumption to disposal, with little thought given to reuse or recycling. Only one U.S. lithium-ion battery recycling facility exists today, the analysts said.

To start to rethink the one-way lifecycle, the NREL team assessed the current state of reuse and recycling of large-format lithium-ion batteries used in EVs and battery energy storage. They found that reusing and recycling the batteries could create U.S. market opportunities, stabilize the supply chain, reduce environmental impacts, and ease resource constraints.

And they found that a circular economy would derive more value from battery energy storage systems. Materials would be reused, recycled, or refurbished for multiple lifetimes rather than one-and-done, which uses up finite resources and creates waste.
