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.

ORNL scientists develop Al-Li hybrid battery

Scientists at Oak Ridge National Laboratory have developed an aluminium-lithium hybrid battery they believe can boost performance for grid and stationary applications.

The hybrid battery uses aluminium as the anode and a lithium intercalation cathode (LiFePO) to increase capacity, cycling performance and safety.
