China on verge of banning large-scale ESSs using second-life lithium-ion batteries

China large-scale ESS lithium-ion batteries

Is China on the verge of banning the use of second-life lithium-ion batteries in large-scale energy storage systems (ESS) amid a spate of fires this year?

The halt will continue until a “breakthrough in battery consistency management technology and a sound power battery performance testing and evaluation system” is developed, according to reports from China media group Caixing.

The ceasing of secondary battery use follows the National Energy Administration issued a draft report ‘Regulations for the Management of New Energy Storage Projects’ on June 22.

What capacity constitutes “large-scale” is not clear.

The Caixing report stated: “According to industry sources, there are few energy storage projects that can be called cascade utilization of large-scale power batteries. In addition, the document does not specify the criteria for defining "large-scale" projects.”

The draft also proposes that completed and operating projects should be regularly evaluated and monitored, and supervision should be strengthened.

Cascade utilisation generally refers to using a battery with less than 80% capacity in EESs for commercial and residential, and telecom base station applications.

In January, an explosion at a China recycling plant owned by lithium-ion battery giant Contemporary Amperex Technology (CATL) killed one person and injured 19 more.

In April, two firefighters died when they were putting out a fire in an energy storage power station in Fengtai District of Beijing, according to the China Daily news outlet.

LG Chem extends ESS recall after concerns with over-heating lithium-ion batteries

LG Energy Solution— an LG Chem subsidiary— will extend its scheme to replace lithium-ion batteries used in its home energy storage systems (ESS) to include all geographical markets.

LG Energy Solution— an LG Chem subsidiary— will extend its scheme to replace lithium-ion batteries used in its home energy storage systems (ESS) to include all geographical markets.

ESSs manufactured between April 2017 and September 2018 are being recalled due to overheating concerns.

The latest scheme expands on similar programs in Australia and the US.

The Korean firm— launched last December by LG Chem— will replace batteries with others that “incorporate manufacturing process improvements that further enhance the safety of its ESS batteries” for free.

All proposed safety measures, including the replacement of the potentially affected ESS batteries, will take place after consultation with customers.

LG Energy Solution will implement remote modifications to the affected batteries, where possible, to reduce the potential for overheating while owners of the affected ESS units wait for their replacement units.

In addition, the firm will update its battery diagnostic and control software. 

Earlier this year, the Korean battery giant made a safety recall over concerns its Resu-branded residential ESSs installed in Australia could overheat and catch on fire.

These concerns came just months after a similar recall in the US, with the company working with the U.S. Consumer Product Safety Commission (CPSC) following reports of five fires with its battery systems.

The latest recall in the UK involves LG Chem’s RESU 10H lithium-ion storage battery that have been installed as part of a residential energy solar panel system.

The serial number of the recalled product begins with R15563P3SSEG and is located behind the access door of the RESU 10H (Type-R) home battery.

A newswire statement from LG Chem read: “LG Energy Solution conducted a review of its manufacturing and quality assurance processes in relation to reported incidents that occurred due to the overheating of the batteries subject to this program. 

“Based on its review, LG Energy Solution has determined that there were certain issues in the early production processes for electrodes used in these potentially affected ESS batteries. “

ESS in flow battery ‘first’ for Latin America

US-based all-iron flow battery system manufacturer Energy Storage Systems (ESS) is making its first foray into the Latin American market.

ESS is to design, install, commission and test its 50-kilowatt/400 kilowatt-hour ‘Energy Warehouse’ system in the Brazilian state of Goiás.

Economics of second-life lithium ESS years from adding up

Mon, 11/28/2016 - 10:03 -- Xuan Zhong

The economics of reusing batteries from plug-in vehicles for residential energy storage systems (ESS) doesn’t make sense, at least according to technology analysts Lux Research.

Lux came to the conclusion after comparing a residential 11.2kWh ESS system using second-life batteries at around $4,600 against a new 7kWh system, at $6,000.

Flow battery partnership to target major ESS markets

US firm ViZn’s zinc and iron flow battery will be used in turnkey large-scale energy storage systems (ESS) following a deal with a vertically integrated utility-scale renewable energy firm.

The strategic partnership with US company Alpha Energy will see the Texas-based firm’s technology used for large behind-the-meter, grid-edge and utility-scale front-of-the-meter applications.
