Novel redox flow battery paves way for low-cost storage
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.
Tdafoq Energy partners India’s Delectrik Systems for GWh-scale vanadium flow battery plant in Saudi Arabia
Tdafoq Energy will use Delectrik Systems’ technology to manufacture vanadium redox flow batteries in Saudi Arabia. Construction has already started on a manufacturing facility in Saudi Arabia, which will be scaled to a GWh capacity by 2025.
Mango Power unveils home and portable battery system
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.
The long read: Cobalt clings on
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.
Non-flammable, graphene-based lithium-ion batteries approaching stationary storage market
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.
Su-vastika launches up to 500 kVA lithium battery UPS
The Indian solar startup has introduced lithium battery-based three-phase uninterruptible power supplies (UPS) with power ratings from 10 kVA to 500 kVA.
PCM-based thermal battery to store solar power via heat pump
Norway’s SINTEF has designed a heat storage system based on phase change materials (PCM) that can support PV generation and peak shaving. The battery’s container hosts 3 tons of liquid biowax based on vegetable oil and is now beating performance expectations at a pilot facility.
Ambri, Reliance Industries sign MoU on liquid-metal battery pilot
Reliance, a strategic investor in US-based Ambri, is purchasing Ambri’s liquid-metal battery system for demo installation as part of its broader energy storage manufacturing plans and deployments in India.
Triton signs EV battery packs, hydrogen fuel cells deal with BEL
The India arm of USA-headquartered Triton Electric Vehicle has issued an INR 8,060 crore (around $971 million) Letter of Intent to state-owned Bharat Electronics Ltd (BEL) for the purchase of EV battery packs. It will also transfer its technology to BEL for production of hydrogen fuel cells in India.
India’s EV charger market to surge at 46.5% annually until 2030
The annual electric vehicle (EV) charger shipments will grow to 0.9 million units by the year 2030, from around 17,000 units in 2021. The growth in sales will be driven by government policies and private investments.
