US-based lead-acid separator firm company Daramic is to open its first end-to-end polyethylene (PE) manufacturing facility in India.
Energy company Innogy SE has bought fellow German large-scale lead-acid energy storage system firm Belectric Solar and Battery.
The two companies signed the relevant share purchase agreement — believed to be in a high double-digit million Euro range— at the end of August, but completion was only announced on January 3.
Indian firm Exide Industries aims to produce the country’s most technically advanced lead-acid battery to date at its new state-of-the-art automotive battery making facility.
The INR 7,000million ($100 million) unit in West Bengal will use punched grid technology, rather than expanded metal technology, to manufacture Exide’s new range of automotive batteries.
The case for bi-polar lead-acid technology and the fortunes of US firm Advanced Battery Concepts received a considerable boost when it agreed a non-exclusive licence deal with Johnson Controls.
The pioneering bi-polar lead-acid developer based in Clare, Michigan, announced the deal with JCI, arguably the largest battery manufacturer in the world.
John W. Wirtz, the founder of US lead-acid battery manufacturing equipment dynasty Wirtz Manufacturing, has died aged 91.
John started the firm, as it is known today, in 1932 after he began working as a machine operator at Wirtz Manufacturing while still in high school.
Chinese battery manufacturer Chaowei Group has founded a new company to make electric vehicles with a choice of lead-acid or lithium-ion battery.
Chaowei has invested ¥3.5 billion ($508 million) into its new company called Zhejiang Plante Electric Vehicle.
Filtration and separation firm Porvair Filtration Group is aiming to drive lead-acid battery innovation with its sintered Polyethylene and Polypropylene Vyon® vents.
The firm believes its Vyon vents will become the industry standard and take over from ceramic for releasing gas during a battery’s operating cycle.
Chinese lead-acid battery firm Senrun Recycling Metal Products has announced a ¥120 million ($17 million) investment in a scrap lead-acid battery recycling project.
The project aims to turn 150,000 mt of scrap batteries into 75,800 mt of refined lead and lead alloy annually at the Metallurgical and Chemical Park of Linxi Industrial Park, Chifeng, City, Inner Mongolia.
Testing has proved that a lead-acid and flywheel hybrid energy storage system can handle renewable energy as a pilot comes to a close in Ireland.
The trial in County Offaly uses a 160kW lead-acid battery from Hitachi Chemical and a 60kW/30kWh flywheel by US company Beacon Power.
The hybrid system by energy consortium Schwungrad Energie, along with transmission system operator EirGrid (Irish Transmission System Operator), has shown the system can handle real-time response and power output requirements.
A Chinese company may have found a way to save 50 million of the country’s lead-acid batteries reaching land-fill after developing an activator it claims can restore the battery’s capacity.
Around two hundred million lead-acid batteries are discarded in China each year, but at least 25% of them could be refurbished, according to Guangzhou Hong Huai Energy Company.
“The core reason of the short life of lead-acid batteries is that the inevitable product Pb2SO4 (lead sulfate) would gradually form irreversible lead sulfate crystals,” Shangnan, Huang, the chairman of Hong Huai Energy Company, said.
The company had successively invested ¥60 million ($9 million) to carry out the development of the battery regeneration technology.
The battery activator in an acidic environment, combined with the external application of working voltage, can catalyse the decomposition of lead sulfate crystals, and then turn sulfate crystals into substances that can continue to participate in chemical reactions, which make batteries become functional again.
Using high-definition electron microscopy the company observed how the Pb2SO4 crystal on the battery plate had a large crystal shape before regeneration. But after repairing, it turns into floc.
However, some cynicism needs to be practiced, because as one battery industry insider told BEST, that equates to around 500,000 tonnes per year, or around $1billion in metal value. So an important question is, if Guangzhou Hong Huai Energy's figure is true, is it going to be cost effective? The insider called the scheme, ahem, 'bovine excrement'— or words to that effect. BEST questions how the company will test the sulfation of that many batteries.
The proof, as they say, will be in the pudding.
