UK firm’s lithium-sulfur cell doubles average lithium-ion equivalent

Thu, 10/13/2016 - 10:12 -- paul Crompton

UK lithium-sulfur firm Oxis Energy has reported its development cell has reached double the specific capacity of an average lithium-ion battery.

Internal tests show the cell reaches 400Wh/kg following three years of work by OXIS scientific team's work on increasing gravimetric energy density of its new ultra-light cell chemistry.

The development was made through a high capacity cathode active material coupled with a newly developed electrolyte formation.

The company’s cells had previously achieved 325Wh/kg in 2015 through its developments on the Innovate UK funded REVB project.

However, it could be two years before these new cells are market ready or being used at an industrial level.

An Oxis spokesman told BEST: “The testing and validation stage for any new battery product entering the market is a lengthy process as the performance and safety must be assessed to international standards by an approval third party testing organization.”

OXIS advanced the energy density through the creation of new lithium-sulfur material formulations, which it integrated along with improving the cell design and production processes.

This was due to a Joint Development Agreement with French chemical corporations company Arkema material, which was present in the iteration of cell design.

A company spokesman said: “The cells are being tested internally at the moment, but will be produced for our partners in the automotive, space and defence sectors in the coming months once internal validation has been completed.

“The collaboration focused on maximising the gravimetric energy through the use of a new high capacity cathode active material coupled with a newly developed electrolyte formation.”

Huw Hampson-Jones, CEO of OXIS said: "Cells are already being deployed for testing for vehicle demonstration and development. Subject to continuing scientific progress, the significance of 400Wh-kg means that the ability to eliminate distance anxiety for consumers will become a reality as well as the eventual replacement of fossilized fuel vehicles."

German project to double battery energy storage

Thu, 10/13/2016 - 09:25 -- Xuan Zhong

Work has begun to double the energy power of a lithium-ion battery-park after the technology proved it was capable of providing grid-scale services in Germany.

The project will see the Schwerin battery-park’s energy output increased to 10MW (14.5MWh) to help stabalise the areas grid frequency as more renewable energy comes on stream.

Japan firm expanding lithium-ion separator output to meet EV demand

Japanese firm Ube Industries is expanding its production capacity for lithium-ion battery separators to 300 million square meters by around 2020.

Expansion plans come as the company builds new production facilities for separators at its Sakai Factory, Osaka Prefecture, Japan.

Ube Industries expansion plans comes as it looks to meet growing demand for lithium-ion batteries for the automotive market.

Once the initial expansion project is completed in April 2018 the company’s Ube Chemical Factory and Sakai Factory will have a combined production capacity of 250 million square meters annually.

Ube Industries began manufacturing separators at the Ube Chemical Factory in Ube City, Yamaguchi Prefecture, in 1994. The Company began production of separators at Sakai Factory in 2013.

In 2011, Ube Industries and Hitachi Maxell, Ltd. established Ube Maxell Co., Ltd., as a joint venture to manufacture high-performance coated separator films.

Nickel metal Hydride technologies fight back from Nice

With lithium-ion products exploding loudly (in press terms at least) two nickel metal hydride manufacturers staged something of a fight back on the battery stage in Nice offering improved across-the-board temperature performance, new electrode alloys and the all important deal closer— reliability.

ARTS Energy, the former SAFT small cell NiMH subsidiary sold off in the last decade, claimed a wide temperature performance (up to 70ºC) and a longer life.
