Tesla reports record energy storage deployment figures

Tesla’s electric vehicle (EV) sales are plummeting, but its energy storage business is surging, with more than 4 GWh deployed in the first quarter of 2024 alone.

Iron-based redox flow battery for grid-scale storage

Researchers in the U.S. have repurposed a commonplace chemical used in water treatment facilities to develop an all-liquid, iron-based redox flow battery for large-scale energy storage. Their lab-scale battery exhibited strong cycling stability over one thousand consecutive charging cycles, while maintaining 98.7% of its original capacity.

Sodium-ion batteries – a viable alternative to lithium?

While lithium ion battery prices are falling again, interest in sodium ion (Na-ion) energy storage has not waned. With a global ramp-up of cell manufacturing capacity under way, it remains unclear whether this promising technology can tip the scales on supply and demand. Marija Maisch reports.

Evaluating the profitability of vanadium flow batteries

Researchers in Italy have estimated the profitability of future vanadium redox flow batteries based on real device and market parameters and found that market evolutions are heading to much more competitive systems, with capital costs down to €260/kWh at a storage duration of 10 hours.

Next-gen battery trends

Lithium ion is the industry standard for a reason. Marija Maisch examines the most promising technological advances that could lead to further improvements in performance and cost from this versatile battery chemistry.

Battery heavyweights reaffirm commitment to solid-state technology

Only weeks after Chinese battery and car manufacturers united as part of a government-led initiative to commercialize solid-state battery technology, South Korea’s Samsung SDI has confirmed its readiness to start mass production of its all-solid-state battery technology with an energy density of 900 Wh/L.

Meyer Burger to shut down plant in Germany and pivot to the U.S.

Swiss solar panel maker Meyer Burger will seek shareholder approval for a rights issue of as much as $284 million to finance the completion of its U.S. manufacturing facilities in Colorado and Arizona.

REC Silicon to shut down polysilicon business in Montana

REC Advanced Silicon Material LLC is shutting down one of its two polysilicon production facilities in the United States. It says the decision is primarily due to regional structural imbalances in supply and demand for electricity.

Suniva to restart idled solar cell factory in Georgia

Suniva ordered equipment for thermal process steps annealing, diffusion and anti-reflective coating and passivation from Germany’s Centrotherm, as it proceeds with plans to expand high-efficiency monocrystalline silicon solar cell production in Norcross, Georgia.

New solid state battery charges in minutes, lasts for thousands of cycles

Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a new lithium metal battery that can be charged and discharged at least 6,000 times — more than any other pouch battery cell — and can be recharged in a matter of minutes.
