Exide increases the ‘green’ credentials of its lead batteries even further

Exide increases the ‘green’ credentials of its lead batteries even further

Exide Technologies has updated its range of after market lead-acid batteries with a focus on using recycled plastic for its boxes and lids to reduce their environmental impact.

The France headquartered firm’s design uses recycled plastic instead of virgin polipropylene (PP) for its a spill and spark-proof security lid.

The new design will be introduced to all of Exide Technologies’ top-of-the-line conventional batteries, with its Exide Premium also using its proprietary Carbon Boost 2.0 technology that uses carbon additives on the negative plates.

The new batteries can be manufactured on existing production lines, with the new design of boxes and lids not requiring any special upgrades of the production lines besides ordinary adjustments.

In its purchasing contract, Exide specifies the boxes and lids bought from outside suppliers are made of recycled plastic instead of virgin PP. 

Guido Scanagatta, senior product manager EMEA at Exide Technologies, told BEST: “We have a material and manufacturing process validation system that is specific to RPP (Reprocessed Polipropylene), which covers several checks on material (dimensions and performance) and adjustment of some parameters in the assembly line (lid to box and secondary lid to main lid thermo welding process mostly).

“Generally, the boxes and the lids are made with injection molding process using either molten virgin or reprocessed PP. The same mold can normally use both materials.”

Exide says the change will lead to savings each manufacturing year of: 2,700 tons of CO2, 8 million litres of water and 1.2 million litres of crude oil.

California’s DTSC removes lead-acid batteries from its toxic watch list

Wed, 05/19/2021 - 08:14 -- Paul Crompton

Lead-acid batteries have been removed from a list of priority products and chemicals under review for potential regulation in the US.

The California's Department of Toxic Substances Control’s (DTSC) ‘2021-23 Priority Product Work Plan’ document omits the batteries for the first time since 2018.

The plan is released every three years under the organisation’s Safer Consumer Products Program (SCPP).

A technical document summarising the information DTSC’s relied on to make its decision is due to be published later this year.

The Battery Council International (BCI) welcomed the news.

A BCI statement said the DTSC’s decision to refrain from listing lead batteries as a “Priority Product” in the SCPP sent an important signal to the energy marketplace.

The organisation hopes the decision will encourage continued investment in lead batteries. 

Roger Miksad, executive vice president of BCI, said: “This outcome is the right one and recognises that lead batteries are critical to meeting America’s energy storage needs and are already well-regulated. 

“The industry’s highly successful closed-loop recycling system and investment in new technologies and innovations also means that lead batteries hold the promise of delivering safe, sustainable energy storage in the future.” 

The agency's decision reflects an evaluation of potential life cycle impacts, current regulations and ongoing product innovation in the lead battery industry.

Lead batteries were placed on the 2018-2020 Priority Product Work Plan, in part, because of lead contamination concerns surrounding the closed Exide battery recycling facility in California.

The report noted: “Based on the findings of our work, we concluded that listing lead-acid batteries as a priority product is not likely to further enhance protection to human health, given that billions of dollars are already being invested worldwide in researching new, safer battery technologies.” 

The SCPP Program will hold a public workshop on lead-acid batteries this summer. 

DTSC will provide short summaries of the ongoing work of the Lead-Acid Battery Recycling Facility Investigation and Cleanup (LABRIC) Program and the Lithium-Ion Car Battery Recycling Advisory Group as context for its decision. 

A BCI statement read: “Lead batteries are a proven technology powering motor vehicles, cargo handling equipment, medical devices, telecommunications infrastructure, microgrids and many other applications across California in a safe, reliable, cost effective and sustainable manner. 

“Ongoing improvements in design and performance position lead batteries as a cornerstone energy storage technology to enable greater utilization of renewable energy resources and 24/7 reliability for residential properties and commercial buildings.”

India’s second biggest lead-acid battery maker has manufacturing suspension lifted

India’s second biggest lead-acid battery maker has manufacturing suspension lifted

Indian firm Amara Raja Batteries has restarted the manufacturing of lead-acid batteries following the closure of two of its plants last month.

The company resumed operations at its Nunegundlapalli and Karkambadi plants on 8 May after the High Court of Andhra Pradesh granted an interim suspension of the orders passed by Andhra Pradesh Pollution Control Board (APPCB), according to India newspaper The Financial Times.

Amara received closure orders for the company's plants in Andhra Pradesh state on 30 April from APPCB.

The closure order was for allegedly violating the Water (Prevention & Control of Pollution) Act, 1974 and Air (Prevention & Control of Pollution) Act, 1981, reported Indian newspapersThe Hindu.

The Hindu reported “The company has been charged with polluting ambient air, which resulted in the presence of high levels of lead in the blood of its employees and people of surrounding villages, discharging untreated wastewater into drains and untreated sewage into stormwater drains and causing soil contamination”.

In a statement, Amara Raja said it had taken proactive measures to ensure its obligations to supply products and services were met without causing any inconvenience; it was assessing the impact of the short-term disruption.

The Financial Times quoted an Amara Raja statement that read: “Continuing with its focus on the best-in-class systems and processes for environmental, safety and health practices, the company will continue to engage closely with APPCB to resolve any potential issues,.” Amara Raja Batteries noted: “We have taken proactive measures to ensure that all our obligations to supply products and services to our customers are met in a timely manner without causing any inconvenience, whatsoever.”

Amara did not reply to BEST’s questions.

Leoch supply lead carbon batteries for narrowboat hybrid drivetrain

Thu, 01/21/2021 - 11:24 -- Paul Crompton

Leoch Battery UK, a subsidiary of Leoch International, has supplied its LC2 series of lead-carbon batteries to power an electric serial hybrid narrowboat. 

The bank of 48v 800Ah batteries will be installed in the engine room of the ‘Old Nick’ narrowboat as a test reference design in this particular application.

Solar, generator and battery statistics will be published to demonstrate how an electric serial hybrid is a practical and cost-effective alternative to diesel.

Paul Sumpner, owner of Old Nick and chief technology officer at Digital Yacht said: “Lead carbon batteries have been overshadowed by lithium batteries in recent years, probably because they do not excel in any one particular area. 

“However, whilst investigating the batteries for Old Nick, it became clear that the combination of cycle life, depth of discharge, safe and flexible installation, cost and most importantly ability to accept regular partial state of charge, make them a really good choice for electric propulsion on a narrowboat.”

Innovative battery chemistry revolutionises zinc-air battery

Wed, 01/13/2021 - 12:07 -- Paul Crompton

Scientists at a German university have developed a new battery chemistry for zinc-air batteries based on an innovative, non-alkaline, aqueous electrolyte.

The full zinc-air batteries can reportedly operate stably for 320 cycles and 1,600 hours under ambient air atmosphere.

US researchers open door for magnesium batteries to disrupt the ESS market

Thu, 12/03/2020 - 09:36 -- Paul Crompton

Researchers from the University of Houston and the Toyota Research Institute of North America (TRINA) have developed a new cathode and electrolyte that could help magnesium batteries compete with lithium-ion.

The teams have demonstrated a magnesium battery capable of operating at room temperature and delivering a power density comparable to that offered by lithium-ion batteries.
