Researchers from Columbia University's engineering department in the US have reported that alkali metal additives, such as potassium ions, can prevent dendritic growth in lithium-ion batteries.
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.
US lithium-ion battery maker Ultralife Corporation has appointed Eric Lind as vice president of commercial operations and business development at its battery and energy group.
Lind will be charged with developing and launching new lithium-based battery products to commercial medical, security and defence, industrial and energy storage markets around the world.
Lind has previously worked for battery manufacturer Duracell, fossil fuel firm ConocoPhillips and lithium iron phosphate battery organisation Lithium Werks.
Lind said: “We see many cell and pack manufacturers chasing the electrification of the consumer automotive sector due to the sheer potential size. Markets such as industrial, medical, defence and robotics are often overlooked by these battery companies as secondary opportunities.
“However, we choose not to serve the automotive industry but rather to focus on these other wide and varied customer segments.”
Battery materials firm Albemarle is due to idle portions of its lithium mine and production facility in the US due to short-term supply-demand imbalances and an excess stockpile of battery-grade lithium.
The North Carolina-headquartered firm’s Silver Peak lithium mine in Nevada and Kings Mountain lithium hydroxide production facility in North Carolina are due to partially close next month until the end of the year.
Test results for US-based intellectual property firm Charge CCV’s (C4V) lithium-ion batteries suggest they can recharge in around six minutes.
The C4V claim to have developed and built an advanced lithium-ion battery that has longer cycle life through its proprietary high-voltage bio-mineralised lithium-mixed-metal-phosphate cathode and anode material.
Construction has begun on the world’s biggest utility-owned lithium-ion energy storage systems by California, US, -based Pacific Gas and Electric Company (PG&E) and Tesla.
Work on the 182.5MW/730MWh system at PG&E's electric substation in Moss Landing, Monterey County will be designed, constructed, and maintained by PG&E and Tesla, and will be owned and operated by the US utility.
A 15-month investigation into an explosion at a lithium-ion battery storage facility operated by the Arizona Public Service (APS) utility in the US has found the cause was a cascading thermal runaway.
The probe into the fire found the explosion on 19 April, 2019, that seriously injured four fire fighters, began with an internal cell failure within one of the battery cells.
An auction for lead-acid battery firm Exide Technologies’ Americas business closed last week with a winning proposal from an affiliate of US private investment firm Atlas Holdings.
Under the terms of the proposed agreement the affiliate of Atlas will acquire all of Exide's ongoing Americas business and operations for around $179 million and assume certain liabilities related to the acquired assets.
US firm Enersys has launched a series of smaller 12V lead-acid batteries for small traction motive power applications using its Thin Plate Pure Lead (TPPL) technology.
Versions of both the firm’s NexSys CORE and PURE blocs have been launched for the OEM and after market applications.
The US’ largest battery storage resource to date was connected to the California Independent System Operator’s (ISO) grid in June— with the 62.5MW lithium-ion system supplying more than a quarter of the area’s battery capacity.
The initial phase of LS Power Group’s Gateway Energy Storage Project in San Diego County signals an era of rapid battery growth for ISO through 2023 as the firm aims toward the state’s procurement targets.
