Tokyo-based JFE Chemical Corporation is reportedly joining forces with Chinese companies to establish a battery materials plant in China to supply the domestic and overseas electric vehicles market.

JFE is acquiring a 40% stake in Chinese joint venture company Wuhai Baojie New Energy Materials with China’s Baowu Carbon Materials & Technology Company holding a 51% stake, China’s state Xinhua News Agency said. The remaining stake will be taken by local firm Tianhe Carbon Corporation.

UK-based residential energy storage firm Moixa has rolled out its GridShare smart battery technology platform to 3,500 homes in Japan.

The move comes just eight months after Moixa agreed to export its battery tech to Japan— under a signed a partnership agreement with the country’s Itochu trading house.

Moixa’s roll-out announcement was made at the British embassy in Tokyo, where the company also launched a GridShare off-peak ‘smart tariff’ for residential battery owners.

Plant-based anodes for lithium batteries

Thu, 08/23/2012 - 18:02 -- Ruth Williams

Chinese companies Kuraray and Kureha are to produce lithium-ion batteries made from plant-based raw materials at a joint factory in Okayama Prefecture.

Traditionally the anode material comes from graphite but the new factory will use ‘hard carbon’ made from plant materials, including coconut shells.  The effect of using the hard carbon will have a more complex crystal structure than conventional graphite.  This will reduce deterioration occurring because of repeated charge – discharge cycles.

The factory for the joint venture will be built at Kuraray Chemical’s carbon plant and will cost US$ 38 159 000.  Output of the factory should be 1 000 tons of anode material annually.  Building work is due to commence in October with plans for the factory to be operational in Autumn 2013 with plans for expansion already being considered.

Hot stuff from W-Scope

Thu, 07/19/2012 - 18:02 -- Ruth Williams

Tokyo-based W-Scope Corporation has developed a separator for lithium-ion batteries that can withstand higher temperatures without damage, increasing safety by reducing the risk of battery fires.

The new separator material can withstand temperatures of 200°C for one minute without damage. In comparison, other separators can only withstand temperatures up to around 160°C, according to W-Scope.

The company has begun shipping samples and plans to begin mass production of the new separator in the second half of the year, offering versions in thicknesses ranging from 0.03 mm to less than 0.01 mm.

W-Scope predicts around 10 firms will begin using its new separators during 2013, and that by 2015 these value-added products will account for roughly 30% of its overall separator shipments.
