Samsung SDI is contemplating opening a battery manufacturing plant in India.
Samsung SDI officials have met India’s telecom and IT minister Ravi Shankar Prasad as a follow-up of their meeting in South Korea to discuss business options.
Samsung SDI is to form a joint venture (JV) for energy storage systems with inverter manufacturer Sungrow in China.
The JV will develop lithium-ion battery energy storage, as well as marketing and sales of its storage solutions and products. The South Korean and Chinese companies plan to establish new firm in the first half of 2015.
US metal-based chemistry firm OM Group has acquired battery maker Ener-Tek International (Ener-Tek) for $24m.
Rhode Island-based Ener-Tek manufactures lithium-ion and silver-zinc batteries for the defence and aerospace markets. According to Ohio-headquartered OM Group, the company aims to offer a wider range of products with the transaction of Ener-Tek and its subsidiary Yardney Technical Products.
Alevo, a hitherto virtually unknown Swiss firm, cut the ribbon on a 4m sq ft lithium-ion battery cell/module manufacturing plant in Concord, North Carolina on 28 October.
Hyped in mainstream media as a “revolutionary” lithium-ion battery, Alevo’s cells are based on standard lithium iron phosphate (LiFePO4), albeit with an inorganic gel electrolyte containing sulphur dioxide and a conductive fluorosulphinate salt that is thermally stable, non-volatile and flame resistant.
China’s BYD and German energy storage firm Fenecon have teamed up to work on several large-scale battery storage projects in the latter's home nation.
In a statement, Bavaria-based Fenecon said the projects will be similar to BYD’s recently opened 40MWh battery storage in Shenzhen, China, which is currently the biggest in the world.
Austria-based battery research firm Varta Micro Innovation (Varta) has researched anode materials for lithium-ion batteries using a customised rolling-ball viscometer.
Varta researched the qualification and optimisation of new electrolytes such as silicon and discovered that the mobility of lithium-ions is greatly dependent on the viscosity of the electrolyte and that viscosity should be a key focus in technology research.
Porsche is to develop an electric vehicle to compete with Tesla’s model S, according to German media outlet Manager Magazin.
Details of the German car marker's first-ever series production electric car remain undisclosed. The model will likely feature a lithium-ion battery developed jointly with Audi. The all-electric driving range is aimed to be about 250 miles. The model will be available with a choice of rear- and all-wheel drive.
Germany’s Manz has developed a laser welding technique to improve the reliability of welded contacts in lithium-ion battery production.
Welded contacts between a battery's individual cells are cheaper and more reliable than screw-on contacts or bimetallic busbars. However, welding surge arrester contacts made of aluminum and copper is technologically demanding, because the resulting weld seam becomes more brittle the more the two differing metals mix.
Singapore’s Nanyang Technological University (NTU) has developed a lithium-ion battery that can be recharged up to 70% in two minutes.
The battery is also designed to have a lifespan of 20 years. Current batteries have a lifespan of 2-3 years and take about 40 minutes to get up to 80% of charge, according to professor Chen Xiaodong from the School of Materials Science and Engineering at NTU.
Michigan-headquartered lithium-ion battery maker A123 Systems has sold its Chinese cathode materials manufacturing facility to chemicals company Johnson Matthey.
A123 Systems retained the ownership of its intellectual property and will maintain its research and development capability of battery materials and to further develop improvements of its lithium iron phosphate (LFP) formulation.
