Key lithium-ion, lead-acid and VRFB materials placed on EU Critical Raw Materials list

Thu, 09/17/2020 - 10:34 -- Paul Crompton

Key lithium-ion, lead-acid and vanadium redox flow battery materials have been placed on the 2020 Battery Critical Raw Materials list by the European Commission.

Lithium, antimony, cobalt, natural graphite, and vanadium have all been placed on the list, which is composed every three years following a review of raw materials for their economic importance and concerns over supply risk.

New chapter for 132-year-old lead-acid battery maker Exide as new firm rises from ashes of bankruptcy

Fri, 09/04/2020 - 09:19 -- Paul Crompton

The US arm of lead-acid battery maker Exide Technologies has been renamed Stryten Manufacturing following the completion of a $179 million buy out by an investment firm.

Stryten will operate seven manufacturing plants across the US to serve the ‘evolving needs of its customers and partners’ after Exide’s Americas business was bought via an auction process in July by Atlas Holdings.

Exide launches App to simplify testing and replacement of its lead batteries

Thu, 09/03/2020 - 12:35 -- Paul Crompton

Exide Technologies in Europe has launched a free battery-testing app to make it easier for workshops to test and replace 12V lead-acid batteries.

The app works on any device with a web browser and is designed to work alongside the Exide EBT965P battery tester, which can test standard, GEL, AGM and EFB 12V batteries.

The next-generation device will allow mechanics to analyse battery test results and give customers battery replacement options within five minutes via SMS or email.

Workshops are alerted as soon as a customer authorises the replacement. Workshops can then present multiple battery options based on the fitment list coming from Exide. 

The system performs advanced analysis on the battery through Conductance Profiling™ technology covering cranking health, voltage, temperature, reserve health capacity and recommendations for further battery treatment such as recharge.

Each test produces a QR code, which the app can scan to import the test results. These test results can also be entered manually.

The app works in most European countries, is available in 13 languages and supports multiple currencies.

Workshops can register for free at ebtp.exide.com. 

This week Exide in Europe launched its grid-focused GNB Marathon FTX range of advanced AGM batteries for telecom and electric utility applications.

The battery uses a MICROCAT® Catalyst to reduce float current and minimise water loss by recombining the hydrogen and oxygen chemically back into water, further increasing the battery lifespan. The firm says this enables a service life of five years at 40°C to reduce the overall cost of ownership— a key consideration when pitting lead-acid against lithium-ion batteries in the above applications.

Second product recall for Ecoult’s lead-based battery technology

Thu, 08/27/2020 - 09:52 -- Paul Crompton

The Australian safety commission has announced a recall of Ecoult’s Ultraflex lead-acid/ultra-capacitor hybrid battery technology due to “risk of fire and electrocution, which may lead to serious injury or death”.

The Australian Competition and Consumer Commission (ACCC) identified the UltraFlex 48-4, 48-3 and 48-2, which was sold through Smart Storage t/as Ecoult and electrical integrators between June 2014 and November 2019. 

The commission statement read: “UltraFlex was not designed to independently protect itself or the user against excessive voltage, overheating, or excessive gassing when combined with particular other equipment in a system.” 

ACCC is asking consumers to immediately contact Ecoult to arrange for the decommissioning and removal of the UltraFlex units by a licensed electrician.

Ecoult will provide a refund and remove the UltraFlex units.

The UltraFlex is designed for commercial, large-residential, microgrid and small-industrial users needing energy storage rated up to 20 kW. It is powered by the firm’s UltraBattery, which combines a Deka 12V lead-acid cell and a lead-carbon ultra-capacitor.

Ecoult’s website states the UltraFlex has been installed both on the grid and on remote off-grid sites.

The recall follows a similar one in New Zealand, which ended on 26 August after Ecoult arranged for the UltraFlex units to be removed by a licensed electrician in the country.

Ecoult had not responded to BEST about the recall at time of going to press.

Project milestone as lithium-ion and lead battery hybrid ESS is delivered to UK port

Wed, 08/19/2020 - 14:37 -- Paul Crompton

A hybrid lithium-ion and lead-acid battery has been delivered to Portsmouth International Port as part of the Port Energy Systems Optimisation (PESO) project.

The 100kW battery will be used to charge electric cars and peak shifting services as the port demonstrates how it can operate as a smart energy network.

The ESS is the only one being used for the pilot project, but if successful the port may order more ‘large scale ones’.

The system, which uses use a hybrid energy storage system supplied by GS Yuasa, is due to come into operation in early 2021.

The batteries are manufactured at GS Yuasa’s Ebbw Vale factory in Wales where final assembly and integration of the entire system takes place. The system’s lithium batteries come from Japan. 

The PESO project is being led by Marine South East supported by Portsmouth International Port alongside Swanbarton and Energy Systems Catapult.

The funding to develop and build the prototype system is coming from Innovate UK's 'Prospering from the Energy Revolution' fund. 

Planned Kenyan recycling plant will regenerate lead batteries for ‘half-price’ re-sale

Thu, 08/13/2020 - 12:11 -- Paul Crompton

Plans to establish a recycling facility in Kenya to prevent the illegal dismantling of lead batteries are moving forward thanks to Betrilyf Solutions, a subsidiary of civil construction firm Avcon Contractors.

The facility at Athi River Township will ‘regenerate’ old batteries with the addition of ‘additives’ before being sold as second-hand at a cost of up to 50% less than new batteries.

US Battery partners with Gridtential Energy to mass market bipolar lead-acid batteries

Fri, 07/31/2020 - 15:57 -- Paul Crompton

Lead battery maker Gridtential Energy has entered into a formal agreement to collaborate on its Silicon Joule™ bipolar battery technology with flooded lead-acid battery firm US Battery.

Under the terms of the agreement, the firms will industrialise bipolar plate pasting and curing processes.

The partnership will also include assembling and testing Silicon Joule™ bipolar AGM batteries using US Battery’s active material.

The goal is to improve the batteries cycle life, energy density, battery efficiency, charging rates and manufacturability. 

Last month, Indian battery maker Amara Raja Batteries announced a partnership with Gridtential Energy to collaborate on bipolar lead-acid batteries— with the former assembling and testing the US-based firm’s Silicon Joule bipolar reference batteries.
