Indian energy management firm Acme has tied up with South Korean company Samsung SDI to manufacture and market lithium-ion batteries in telecom, solar power, defence sectors and other allied industries in India and the African continent.

Cummins Power Generation has launched a website specifically focused on product and technical information to support the needs of its data centre customers.

In a statement, Cummins said the launch of http://cumminsdatapower.com reflected the need for information in one of the biggest growth segments in the world today – backup power for data centres.

Brent Ness, Global Data Centre Segment Leader for Cummins Power Generation, said: “We continually hear from data centre customers and from consulting engineers around the world that they want fast, easy access to information directly related to data centre product offerings,” said

“This website not only contains product information, it also includes technical bulletins, white papers and other information relevant to the application, operation and maintenance of the complete backup power system in data centres.” 

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.

Energetix subsidiary Energetix Pnu Power has received a UK patent for an important method relating to the core technology within its compressed air uninterruptible power supply products.

The patent - titled 'Lubrication of Positive Displacement Expanders' - describes the method by which efficiency of the conversion of compressed air into electrical power can be optimised with minimal lubrication of mechanical components. Pnu Power produces back-up power solutions, using compressed air, for utility switching, telecommunications, data centres and other mission critical industrial operations.

Energetix says the grant of this patent provides additional protection to the company's core product platform and builds on the company's intellectual property portfolio relating to its Pnu Power technology.

The company has a core patent granted in 20 countries which protects its compressed air driven UPS system as well as two further patents providing additional protection. 

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 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.
