lithium-ion battery

Swedish battery maker Northvolt has developed its first sodium-ion battery in partnership with Uppsala University spinoff Altris. The cell has been validated for an energy density of more than 160 Wh/kg and is designed primarily for energy storage applications.

Researchers at the University of Hong Kong (HKU) have developed a quasi-solid-state magnesium-ion battery with a voltage plateau at 2.4 V and an energy density of 264 Wh/kg. It surpasses the performance of current magnesium-ion batteries and almost matches the performance of lithium-ion batteries.

US-based Sage Geosystems has presented field results showing that its Earthstore underground storage system can provide 18 hours or more of storage capacity, in addition to short-duration power. The solution is said to be cost-competitive with lithium-ion batteries and natural gas peaker plants.

The Brazilian town of Vale do Jequitinhonha (MG), which stands out worldwide in mineral production, is the stage of a multisectoral program for the use of Brazilian lithium. The government is now exploring the opportunities of the area in the energy transition.

Nuvola Technology says it has developed a direct deposition polymer separator technology that can eliminate the primary cause of lithium-ion battery fires.

Brisbane-based Li-S Energy has developed a 20-layer battery cell utilizing semi-solid state lithium sulfur battery technology. The company claims the new cell displays nearly double the gravimetric energy density and a comparable volumetric energy density to lithium-ion cells.

UK researchers have assessed the cost of a 24V soluble lead flow battery optimized for PV applications. They have found that a total component cost of GBP 50 ($62)/kWh could be achieved, which is half that of current nickel-manganese-cobalt (NMC) lithium-ion cells.

Researchers at the University of Cambridge have examined one of the fastest-charging anode materials by using a low-cost, lab-based optical microscopy technique. Their findings showed that particle fracture, which can reduce the storage capacity of a battery, is more common with higher rates of delithiation and in longer particles.

Researchers in Russia have developed a new sodium-vanadium phosphate fluoride powder. It has a particular crystal structure that provides superior energy storage capacity in the battery cathode.

The U.S. battery specialist has signed framework agreements with four developers to deliver systems for multiple projects.
