Edinburgh-based energy storage solutions specialist StorTera has developed a long-duration, energy-dense, lithium-sulfur-based single liquid flow battery (SLIQ). The tech is said to last for 30 years with minimal degradation.
KU Leuven researchers have developed rooftop panels that capture both solar power and water from the air. Like traditional PV modules, hydrogen panels are also connected, but via gas tubes instead of electric cables. The researchers are now preparing to bring the tech to the mass market via a spinoff company.
US researchers have facilitated the decoupling of power from energy design by incorporating a conducting carbon slurry in the negative electrolyte of an all-iron flow battery. In a new study, they describe the design considerations for slurry iron redox flow battery scalability.
US-based Mango Power has developed a 3.5 kWh battery system that can be expanded up to 14 kWh. The product features LFP battery cells from CATL and can be charged through AC wall outlets, with solar panels, or via electric-vehicle chargers.
Cobalt is key for boosting energy density and battery life, but it comes with caveats: expensive, scarce, and linked to unethical mining practices, wild price fluctuations, and a tenuous supply chain. In recent years, battery manufacturers and automakers have intensified efforts to reduce or eliminate cobalt in lithium-ion cathodes. But sometimes, old habits die hard, as pv magazine’s Marija Maisch explains.
US-based Nanotech Energy’s graphene battery uses proprietary electrodes with a thermally stable separator, and non-flammable electrolyte that is said to be inexpensive to manufacture. The technology is said to be superior in terms of safety and competitive in terms of cell performance.
Record energy prices, particularly in Europe, are driving demand for renewables and energy storage. That is changing the equation for utility solar and wind investment and shortening project payback times to under a year in some regions. Storage deployment, driven by recent policy developments around the world, is also expected to get a big boost through to 2030.
A couple of weeks ago, Goldman Sachs sent shockwaves through battery metals markets, issuing a prediction that cobalt and lithium in particular were due for a sharp price decline in the next two years. But London-based Benchmark Mineral Intelligence is loudly pushing back, outlining its reasons why it believes the call on lithium was wrong. Meanwhile, US analyst Wood Mackenzie says that the battery raw material chain will remain tight, but notes that recycling could help to ease the supply deficit.
South Korean battery manufacturer LG Energy Solution presented its latest innovations at the Smarter E event in Munich last week. It also announced its transition from nickel-manganese-cobalt (NMC) battery chemistry to lithium iron phosphate (LFP) in its future products.
