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.

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.

China Racing has announced it will be taking part in the Formula E Championship electric vehicle race series in 2014. China Racing is the second of ten teams to be confirmed for the zero-emission race after UK-based Drayson Racing Technologies.

The teams will race on street circuits in ten cities across the world in electric cars. The cars for the inaugural year are being designed by McClaren, Spark Racing Technology and Dallara. All teams have the opportunity to use the customer car for the first year and encouraged to build their own cars for races in the following years. With support from Chinese automotive makers China Racing hopes to build a team car within three years.

(L-R): CEO Team China Racing – Steven Lu, Chairman Team China Racing - Yu Liu, FIA President - Jean Todt, First Secretary of the Chinese Embassy - Mr. Liang JianSheng, CEO Formula E Holdings - Alejandro Agag.

Alejandro Agag, Chief Executive Officer of Formula E Holdings said: “China has enormous potential for the expansion of electric vehicles as a tool to fight pollution in cities. We think the FIA Formula E Championship can be a powerful tool to make electric cars popular with the Chinese public, particularly the younger generations. Having a Chinese team with us in the Championship will be key to succeeding in that challenge.”

Porous Power separator reduces risk of thermal runaway

Porous Power Technologies (PPT) has launched a line of ceramic-filled battery separators designed to improve the thermal stability and safety of the large-format lithium-ion batteries used in electric vehicles, flat-cell consumer electronics, and high-power applications.

Under heat, the ceramic-filled polymer separators fuse together, leaving a thin film of ceramic particles between the electrodes and reduce the likelihood of hard shorts that can lead to thermal runaway and cell failure.

The ceramic particles are evenly distributed throughout the PPT chemically inert PVDF polymer. The particles reside primarily in the pore walls, leaving a large and uniform open pore structure that enable ions to pass through with less resistance and less heat generation.

The separators will provide greater power in high-current applications as well as having increased thermal stability with less cell degradation. The design offers reduced separator shrinkage, extended cycle life, higher bake-out and operating temperatures, and improved puncture and abuse resistance.

German chemical giant BASF has released its sales figures for 2012 showing growth across the company. The chemical segment overall sales figures grew 7% on 2011, the 2012 sales increased to €13.8billion. There was however a decline in EBIT (earnings before interest and tax) due to plant shut downs and lower margins.


The tables below show the full figures for 2012 compared to the previous year across the range of the company (bottom) as well as the fourth quarter sales figures (top).

Advances in charging for smart devices mean longer run times

Chinese portable power company Powerocks has an ever growing range of mobile phone power boosting accessories. The high capacity portable batteries provide additional power for mobile and tablet devices that are compatible with USB ports.

The lithium-ion batteries can be charged form a mains power supply and then provide several re-charges for smart phones and tablet devices. The slim-line design of iPhones and the like mean the battery cannot be swapped with a spare, it must be recharged, resulting in companies coming up with novel ways to help users re-charge when travelling or away from mains charging.

The range includes the Stone series of portable batteries that offer between 5800mAh and 7800mAh capacity, which provide an additional three times power for devices; The Magicstick is the size of an AA cell and offers 2600mAH power on the go for phone devices. 

The MagicstickThe ultimate in portable battery is built into the phone cover. The interestingly named Cheese Crystal is a protective case for the iPhone4 that has an 1800mAH lithium-ion battery incorporated in it to double potential battery life.

When charged, Powerocks range can power up to two devices, dependant on model, two or three times. The designs are complimentary to Apple style and show these chargers can be sleek and elegant but still pack a lot of power.

Smart heating system could cut bills and increase use of renewables

An energy efficient heating system offering efficiency savings of up to 20% could be key in the transition to low-carbon energy systems in Europe. This is according to a report commissioned by SSE (UK energy generators and distributors) and Dimplex (a global heating solutions firm).

The smart electric thermal storage (SETS) system works by storing up renewably produced energy when production is high but demand is low. The report indicated SETS could provide up to 54GW of additional flexible storage capacity across Europe by 2050, enabling renewable electricity to be stored when demand is low and used to heat homes when needed.

The system, first brought to the market by SEE and Dimplex in a product called Quantum, is intended to replace out-dated night storage heaters with something more efficient and with better room temperature control as well as being designed for smart grid integration.

The report found that if all 27 EU countries replaced storage heaters with SETS, savings of 7.4TWh of electricity and three mega-tons of CO2 could be made each year. If used in all electrically heated homes as much as 148GW could be provided by 2050.

Stuart Mackenzie, Managing Director of Dimplex, added: “Quantum offers consumers with electric storage heaters the opportunity to reduce their running costs by up to 27%. It’s also a Green Deal approved measure, so the capital cost outlay can be substantially reduced.”

Aggreko appoints director for Europe, Middle East and Africa

Aggreko has announced the appointment of David Taylor-Smith as its new director for Europe, Middle East and Africa, with effect from 11 March 2013.

Former British Army officer Taylor-Smith has spent most of his career in the security industry. The 51 year-old worked for G4S between 1998 and 2012, most recently in the role of Chief Operating Officer and Regional Chief Executive of UK, Ireland and Africa.

Taylor-Smith resigned from G4S last September after the company failed to provide an adequate number of security staff for the London Olympic Games, forcing British police and the British Army to intervene. The company eventually booked a loss of $108m on the project.

The appointment follows the management reorganisation announced by Aggreko last September, with the group being split into three regional units for the Americas; Europe, the Middle East and Africa (EMEA); and Asia, Pacific and Australia (APAC), each managed by a main board director.

The Americas and APAC posts were filled by internal candidates - Asterios Satrazemis and Debajit Das, respectively.
