lithium-ion battery

KPIT, an India-based automotive software and engineering solutions supplier, has unveiled its proprietary sodium-ion battery technology, and is now on the lookout for manufacturing partners. Ravi Pandit, chairman of KPIT, tells pv magazine, that that the company has developed multiple variants with energy density ranging from 100 Wh/kg to 170 Wh/kg, and potentially reaching 220 Wh/kg.

Nilar, a Swedish producer of nickel metal hydride batteries, has filed for insolvency and is now looking for a new owner.

For the seventh year in the row, China-based Contemporary Amperex Technology Co. (CATL) looks set to claim the title of the world’s biggest battery maker. There are a number of reasons why it continues to maintain its lead in the electric vehicle (EV) and battery energy storage system (BESS) markets..

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.
