Lead-acid growth for Hitachi

Wed, 08/15/2012 - 18:02 -- Ruth Williams

Hitachi Chemical Co will increase its production capacity for industrial lead-acid batteries by next January by expanding facilities of the subsidiary company Shin-Kobe Electric Machinery Co.

Some US$12 750000 (one billion yen) will be spent on constructing a building with a new assembly line at Shin-Kobe's Nabari Works in Mie Prefecture, the main site making lead-acid batteries.  It is estimated cell production capacity is likely to increase by 50%.

The site will make back-up power source batteries, the LL-W series of which demand is growing for in offices and factories at risk of power failures.  Joining 192 LL-W batteries together can produce 40kw of electricity for around ten hours.

Shin-Kobe Co. accounts for roughly 30% of the domestic market for industrial lead-acid batteries.  The LL-W products claim a battery life of 17 years, one of the world's longest, and are a fraction of the cost of a lithium-ion counterpart. 

Second Life for lithium-ion

Wed, 07/25/2012 - 18:02 -- Ruth Williams

The ‘second life’ potential of batteries is a hot topic at the moment with the rise in EVs meaning more lithium-ion batteries will be in circulation, including the Nissan Leaf being mass-produced in the UK from 2013.  ABB and Zero Carbon Futures are both researching the potential utilisation of ‘used’ batteries.  When the batteries come out of the cars they would still have around 80% capacity, this would reduce the range of the car but still be sufficient to be put to another application.  Zero Carbon Futures, working alongside Nissan, are researching the energy storage potential of the used batteries for home energy management systems.

A123 sign two deals in as many days

Mon, 07/23/2012 - 18:02 -- Ruth Williams

This July A123 announced they shall be supplying BAE Systems with lithium-ion battery packs for its new HybriDrive Series to be used on municipal buses. The following day A123 signed a deal with Chinese Ray Power Systems to supply a grid energy storage system.  This is great news for shareholders of A123.  Share price has risen for the first time since the company announced in June that it is struggling financially. 

South Korea battery exports reach new high

Mon, 07/23/2012 - 18:02 -- Ruth Williams

South Korea shipped 20% more rechargeable batteries overseas in 2011 finacial year than the previous year.  Of these, 56% were lithium-ion making South Korea the world’s largest exporter of lithium-ion batteries for 2011.  The exports of the batteries were valued at US$3.8 billion according to the Korea Customs Service.

Emergency home power from EVs

Mon, 07/23/2012 - 18:02 -- Ruth Williams

Progress is being made to develop EV batteries to be utilised to power homes during times of blackout. Following the 2011 Japanese earthquake much of the country was without electricity, EV batteries were used as a temporary in-home power supply.  Hybrid cars that feature an invertor can have the high-voltage direct current switched to a low-voltage alternating current to supply power back to a home at times of blackout. Nissan are leading the way in advancing this potential, they believe their Leaf car could power a home for up to two days, or individual appliances for far longer.

Growth for Johnson Controls

Fri, 07/20/2012 - 18:02 -- Ruth Williams

Johnson Controls Inc. has begun a new partnership with PolyPlus Battery Corporation, a California-based battery manufacturer, and also announced plans for a Chinese automotive battery plant. 

PolyPlus will receive US$8.99 million from the US Department of Energy to invest in manufacturing lithium-ion batteries over the next three years.

PolyPlus is developing batteries that are lighter store more energy than the lithium-ion batteries that Johnson Controls currently produces.

Johnson Controls also announced this week signing a deal in China for a facility producing batteries for stop-start vehicles. It will be the first of its kind the company has in China.

New battery plant in South Korea

Fri, 07/20/2012 - 18:02 -- Ruth Williams

A plant to make components for lithium-ion batteries is to be built in South Korea by Belgian company Umicore. 

The high-tech recycler and specialist materials maker will double its capacity of the product as it expands into the market.  The plant should be operational in 2014 to make parts for rechargeable batteries.

Lithium-ion without the rare earth metals

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

A Tohoku University researcher last month announced the development of a lithium-ion battery whose positive electrode does not use any rare earth metals.

Conventional lithium-ion batteries do use rare metals, such as cobalt and nickel, in the positive electrode. Due to their geochemical properties rare earth elements can be dispersed and often not found in concentrated or economically exploitable forms.  This makes these metals costly, and supplies not always stable. Eliminating them will likely make the batteries cheaper to manufacture.

China announced plans in 2009 to reduce its export quota of rare earth minerals to around 350,000 tons per year to conserve scarce resources and protect the environment.  This has led to other countries stock-piling their reserves.  The EU, US and Japan have brought a complaint to the World Trade Organisation alleging China is restricting the exports to maximize domestic use and thus distort the global economy.

Professor Itaru Honma of Tohoku University's Institute of Multidisciplinary Research for Advanced Materials has succeeded in replacing these metals with organic substances. As a result, costs of materials for the positive electrode have been slashed to less than one-fifth what they were before.

Professor Honma made a button-sized lithium-ion battery for testing. This prototype achieved an energy density of 200 watt-hours per kilogram -- roughly double that of current lithium-ion batteries. Tests confirmed that the button-sized battery could withstand at least 100 charge-discharge cycles.

The next step will be to look further for organic materials that more efficiently store power and boost the battery's capacity, with a goal of developing a secondary battery for electric vehicles.

New York battery plans to expand

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

General Electric Co said it will invest $70 million in its Schenectady battery plant in New York to double production and create 100 jobs there.  This will take the plant’s workforce 450 at full capacity.
The factory manufactures GE's Durathon batteries, which are half the size of conventional lead-acid batteries but last ten times longer.

On track for a smaller more economical hybrid

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

A Japanese hybrid train company has made an engine 45% smaller and 20% more economical on fuel than conventional diesel locomotives.  Kinki Sharyo use a diesel engine combined with lithium-ion batteries.  Unlike diesel trains the hybrid only requires one engine for two locomotives making it lighter and more economical on fuel.
