CATL: Staying on top of the battery game

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.


New solution to suppress battery storage fire, thermal runaway unveiled by Fike

Fike Corp., a US industrial-hazard protection specialist, has launched Fike Blue, a tested, patented solution that suppresses battery fires and stops cascading thermal runaway.

Northvolt unveils 160 Wh/kg sodium-ion battery

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

Weekend read: Australia’s big BESS, big bet

As Australia’s big battery fleet continues to charge ahead, the battery revenue stack is evolving – and so are financing opportunities.


Weekend read: Australia-made batteries for easier repair, recycling

Brisbane-based Vaulta has developed a lighter, smaller battery casing with fewer parts, which makes it easier to assemble modules and repair faulty components. CEO Dominic Spooner argues that the company’s patented technology has the potential to significantly reduce battery waste.

RMIT software tool unlocks BIPV design

RMIT University in Australia has developed new software that integrates product, regulation, technical, economic, and construction data. It helps architects and engineers to estimate the cost of building-integrated photovoltaics (BIPV) during the conceptual design phase.

Three steps to reduce battery storage fire risk

Lithium-ion batteries are generally safe and unlikely to fail, but they can catch fire if damaged, stored, or operated incorrectly. With calls mounting for development of engineering good practice, US-based Firetrace International suggests three steps that battery manufacturers, developers and operators should take into account.

Weekend read: More than ‘an alternative’

Sodium-ion batteries could diversify the battery supply chain and take the weight off the shoulders of ubiquitous lithium-ion technology. pv magazine sits down with Florian Kogler, head of safety and user experience at Austrian sodium-ion battery business Kite Rise, to discuss the technology’s potential and the company’s development plans for batteries made in Europe.


Distributed PV, battery storage curtailment in low-voltage networks

University of New South Wales (UNSW) researchers have looked at energy losses in South Australia and have identified average curtailment of 1.5% for distributed PV sites and 0.2% for distributed PV coupled with batteries, but some locations experience generation losses of up to 25%.


Separator tech to prevent battery fires

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