Researchers from Dongguk University have achieved a significant breakthrough in lithium-ion battery technology by developing a novel hybrid anode material. This innovative study introduces a hierarchical heterostructure composite that optimizes material interfaces at the nanoscale, resulting in remarkable enhancements in energy storage capacity and long-term cycling stability. This engineered structure integrates graphene oxide's superior conductivity with the energy storage capabilities of nickel-iron compounds for future electronics and energy solutions.

Lithium-ion batteries are the dominant energy storage technology powering everything from portable electronics to electric vehicles and renewable energy systems. However, the demand for higher energy density, faster charging, and longer lifespans necessitates continuous innovation.

Researchers, led by Professor Jae-Min Oh of Dongguk University, in collaboration with Seung-Min Paek of Kyungpook National University, are addressing these challenges by engineering materials at the nanoscale. Their work, available online on January 28, 2025, and published in volume 506 of the Chemical Engineering Journal on January 15, 2025, focuses on a novel hybrid material designed to maximize the synergistic effects of its components. This innovative composite is a hierarchical heterostructure that combines reduced graphene oxide (rGO) with nickel-iron layered double hydroxides (NiFe-LDH). This unique composite leverages the properties of its components: rGO provides a conductive network for electron transport, and the nickel-iron-oxide components enable fast charge storage through a pseudocapacitive mechanism. The key to this innovative design is the abundance of grain boundaries, which facilitate efficient charge storage.

To achieve the final composite, the researchers employed a layer-by-layer self-assembly technique using polystyrene (PS) bead templates. First, the PS beads were coated with GO and NiFe-LDH precursors. The templates were then removed, leaving behind a hollow sphere architecture. Following this, a controlled thermal treatment induced a phase transformation in NiFe-LDH, leading to the formation of nanocrystalline nickel-iron oxide (NiFe₂O₄) and amorphous nickel oxide (a-NiO), while simultaneously reducing GO to rGO. This synthesis resulted in a well-integrated hybrid composite (rGO/NiFe₂O₄/a-NiO), with enhanced conductivity making it an efficient anode material for lithium-ion batteries. This hollow structure prevents direct contact between the a-NiO/NiFe₂O₄ nanoparticles and the electrolyte, improving stability.

Advanced characterization techniques, such as X-ray diffraction and transmission electron microscopy, were then used to confirm the composite's formation. Electrochemical tests revealed the material's exceptional performance as a lithium-ion battery anode. The anode demonstrated a high specific capacity of 1687.6 mA h g⁻¹ at a current density of 100 mA g⁻¹ after 580 cycles, surpassing conventional materials and highlighting its excellent cycling stability. Furthermore, the material exhibited good rate performance, maintaining high capacity even at significantly increased charge/discharge rates.

Professor Seung-Min Paek emphasized the collaborative nature of the research, "This breakthrough was made possible through close cooperation between experts in diverse materials. By combining our strengths, we were able to design and optimize this hybrid system more effectively. "

Professor Jae-Min Oh added, "We anticipate that, in the near future, energy storage materials will move beyond simply improving individual components. Instead, they will involve multiple interacting materials that create synergy, resulting in more efficient and reliable energy storage devices. This research offers a pathway to smaller, lighter, and more efficient energy storage for next-generation electronic devices."

This development targets significantly improved batteries (longer life, faster charge, lighter) within 5-10 years, benefiting both device users and sustainable energy initiatives.

Galp, Portugal’s leading integrated energy company, and Powin, a U.S. based global energy storage integrator, completed the commissioning and injected the first electrons of stored energy to the grid from a utility-scale battery energy storage system at Galp’s largest solar power plant in the country.

Installed near Alcoutim, in the southern region of the Algarve, the 5 MW/20 MWh battery system, Powin’s first project in Europe, enhances the site’s ability to dispatch renewable energy to the grid when it needs it most and optimizes grid stability, thus becoming an important tool in the expanding market for grid system services.

With a combined capacity of 144 MW, the plants in the Alcoutim region produce enough energy to power 80,000 homes while avoiding 75,000 tons of CO2 emissions per year.

“We are leaping ahead in the learning curve, managing complex energy systems and offering a new range of services and opportunities to customers, while contributing to a stable and sustainable energy system,” said Georgios Papadimitriou, Galp’s Executive Vice-President of Renewables, New Business, and Innovation.

“This project represents a critical step in Powin’s journey as we expand internationally to meet the growing demand for energy storage solutions in Europe,” said Brian Kane, Chief Projects Officer at Powin. “By partnering with forward-thinking organizations like Galp and leveraging high-performance converter technology from Hitachi Energy, we’ve demonstrated our ability to deliver reliable and innovative solutions that help decarbonize the grid.”

The battery energy storage project utilizes Powin's Centipede Stack750 and a power conversion system from Hitachi Energy, underscoring the importance of partnership between global companies in supporting Europe’s energy transition.

“We appreciate the ongoing relationship with Powin and Galp,” said Alberto Prieto, Head of Power Conversion Solutions for Hitachi Energy. “Our converters remain the prime choice for IPPs and integrators seeking grid stability and flexibility, along with digital enablement for operations and business processes for a more sustainable and secure grid.”

Galp is one of the main producers of photovoltaic solar energy in the Iberian Peninsula, with 1.5 GW of installed renewable generation capacity and 400 MW new renewable capacity to be installed by 2026.

Spruce Power Holding Corporation (NYSE: SPRU) (“Spruce” or the “Company”) announced the signing of a new Spruce Pro servicing partnership with commercial & industrial (“C&I”) and residential solar installer Hot Purple Energy (“Hot Purple”) to monetize Solar Renewable Energy Credits (“SREC”) in California.

This partnership is part of a broader Spruce initiative to leverage the Company’s platform and experience to capture the unrealized benefit of SREC credits for installers and C&I operators. As part of this agreement, Spruce will be responsible for initial and ongoing registration and monetization of Hot Purple’s SRECs with the Western Renewable Energy Generation Information System (“WREGIS”). The Company will also manage the monthly reporting of production and sale of SRECs for Hot Purple’s solar generation assets, generating cash flow for both Spruce and Hot Purple.

“Recent market changes in California have made registering SRECs financially rewarding for the first time, more closely aligning with mature SREC markets in certain states on the East Coast,” said Chris Hayes, Chief Executive Officer of Spruce. “We view scaling SREC registration in California as a low cost, low risk opportunity to generate high margin, cash flow for the Company.”

Hayes continued, “Spruce is among a very small number of companies that have completed the approval process to enable monetization of dormant SREC revenue within all three of California’s largest utility zones. This puts Spruce in a unique position to capitalize on a meaningful market opportunity. We are in active discussions for the rights to acquire SRECs from significant 3rd party installers as well as numerous mid-size and local companies that own residential and C&I solar sites in the state.”

Hayes concluded, “The monetization of SRECs plays to our strengths and has strong potential to deliver capital-light growth. Typical contracts will generate approximately 7 years of cash flow, allowing Spruce to grow our SREC trading book in California.”
