Kurt Kelty winner of the Cambridge Enertech battery innovator of the year award and Senior Director, Cell Supply Chain and Business Development at Tesla Motors told BBB that the company did not rule out becoming a mining company as it consolidates its position into becoming the biggest user and manufacturer of lithium ion cells in the world.
A new eco-friendly battery using salt water is being jointly developed and commercialised by three Korean research organisations.
The new battery collects sodium ions from seawater during charging and stores them in the cathode. Then during discharge the anode releases sodium, which reacts with water and oxygen to form sodium hydroxide.
This produces electricity without auxiliary loads or an external power supply, meaning it could be applied on both residential and industrial scales.
The project’s consortium consists of Korea Electric Power Corporation (KEPCO), Korea East-West Power Company Ltd. (EWP), and the Ulsan National Institute of Science and Technology (UNIST).
UNIST has signed a memorandum-of-understanding with KEPCO and EWP to set up the joint research on commercialisation of the seawater battery in last week.
The consortium will establish a testing facility to produce the batteries, and plan to build a 10Wh seawater battery pack at Ulsan Thermal Power Plant, South Korea by 2018.
Compared to the lithium-ion batteries, the consortium believes the seawater battery will be more ‘cost-effective’, and safer than lithium-ion, but with relatively low electric power, according to UNIST’s report.
To enhance the battery charge rate by 20Wh, the study will design different sizes of cells and shapes and standardise procedures of battery.
The Korean government has granted ₩7 billion ($6.1 million) to UNIST since the research started in 2014. ₩3 billion ($2.6 million) and ₩2 billion ($1.8 million) will be respectively granted to the project by KEPCO and EWP by 2019 and 2018.
Professor Youngsik Kim of Energy and Chemical Engineering at UNIST is optimistic of his batteries ability to take on lithium-ion and lead-acid.
He said: “Once this battery is commercialised, we can lead the ₩47 trillion ($41 billion) worth, advanced energy storage devices market.”
Professor Kim’s venture, ‘4 to One’ has been producing and selling coin-shaped seawater batteries and test kits.
Professor Kim has also transferred the solid ceramic electrolyte synthesis technique, one of the core materials of the seawater batteries, to a local SME, Ce&Chem Co. Ltd. in 2015.
That company now produces more than 100,000 solid ceramic electrolytes a year.
Speed of deployment and rapid demand response functions at grid-scale has seen California embrace battery energy storage systems in the face of potential blackouts.
Just over a year since a gas leak in the Aliso Canyon region of the US state utility Southern California Edison (SCE) has been busy tendering projects to tackle the threat of blackouts in the area.
Two major battery and electric drive train suppliers introduced 48 volt systems for the European and Chinese vehicle markets at AABC last week— to the surprise of many analysts.
The 48 volt concept has been dismissed as ‘without value’ by Menachem Anderman, perhaps the most prominent industry watcher.
A stream of lithium battery solutions from some of the big names in lithium-ion manufacturing and automotive systems suppliers were presented at AABC. And they seem to provide all the answers to the OEM’s emission targets for 2021 and 2030.
Chris Ferhenbacher, from A123 Systems, showed real data that appeared to prove conclusively that lithium-ion with their latest phosphate technology is superior to an equivalent AGM battery, even at -30C.
Two management level employees have moved from Eaglepicher and taken half a century of combined battery knowledge to nickel-zinc battery start-up Zaf Energy.
Randy A. Moore has been named as Zaf’s new president and CEO, with Tom Shireman joining the US firm to lead manufacturing operations at the Montana-based company.
Canadian firm Eguana Technologies has augmented its energy storage partnership with Korean lithium-ion battery giant LG Chem.
Eguana has begun integrating LG Chem’s JH3 cell technology into its AC Battery energy storage system (ESS) portfolio.
Researchers at Stanford University have developed a lithium-ion battery that releases a flame retardant if the battery temperature hits 160°C, according to the academic journal Science Advances.
The technology would have implications throughout the lithium-ion battery industry, which has been hit in the last year by product fires and airline shipment bans.
