Achieves More Than Double Capacitance

with 600 Multilayers

TAIYO YUDEN released the world’s irst EIA 0603

size 47μF large capacitance multilayer ceramic

capacitor, which has been realized with a length

tolerance of 1.6+0.2/-0mm, and a width and

thickness tolerance of 0.8+0.2/-0mm, as a super

high-end product for devices that are witnessing

rapid growth such as smartphones and tablet PCs.

TAIYO YUDEN announced the commercialization

of its embedded-parts multilayer wiring substrate

“EOMIN ® (Embedded Organic Module Involved

Nanotechnology)” that incorporates a copper

core, technology developed to accommodate

multiple built-in ICs.

This product is an embedded-parts multilayer ...

Drawing on the state-of-the-art technology of

TAIYO YUDEN, such as laminating and thin-layer

technology, multilayering of 600 layers has been

achieved at an EIA 0603 size, which represents an

improvement of more than double on our previous

maximum capacitance of 22μF for an EIA 0603

size multilayer ceramic capacitor. It is ideal for

decoupling applications for the IC power-supply

EDITORIAL COMMENT

Desperate for power

Everyone has experienced the panic of a ‘battery low’ signal on a handheld device. The fear of losing

data or being out of contact has gripped everyone’s heart at some point. Playing on our quest for

interminable battery power, those minxes at Digital Core Design announced they had developed a

graphene processor which could work for three months on a single battery charge. It fooled many (some

publications ran the story - on April Fools’ Day). The prank proved two things – everyone wants longer

battery life and the accuracy of the saying “if something sounds too good to be true, it probably is”.

By Caroline

Hayes,

Editor-in-Chief,

EPN

Other, more realistic, propositions have been put forward recently which have also grabbed headlines

but there are drawbacks to them too. Infinite Power Solutions has demonstrated a paper-thin battery

to replace conventional lithium-ion batteries manufactured using double-sided deposition and with a

capacity density of 1.25mAh/cm 2 . This is equivalent to prismatic lithium-ion cells but without the risk of

thermal drain. The production costs are comparable to prismatic lithium-ion cells, says the company, and

the batteries provide 700Wh/litre which is a 25% increase in energy density over today’s lithium-ion cells.

The fact that the battery is paper thin means it can be shaped promising more energy density as well as

end-product design creativity.

High-capacity cells can be stacked to form a 3.95V all-solid-state, thin-film battery pack about the size

and thinness of five standard playing cards. Such a battery would have a capacity of approximately

1.4Ah with a maximum current of 7A. There is no organic liquid or gel electrolyte to be contained, so the

battery can be encapsulated in a thin, flexible circuit.

Jim Norrod, president and CEO, explains the challenges of battery design: “It is extremely difficult to

maintain high energy density, regardless of the battery chemistry, as the cell thickness is reduced. This

is especially true when going below 2mm thickness for a fully packaged battery. The drawback? The

company cannot give a date for availability. Tim Bradow, the company’s VP marketing said that the

announcement was a ‘call to action’ for the industry (and potential partners) to scale up manufacturing

to bring these batteries to market for consumer products.

Another company, Envia Systems, has also been concentrating on lithium-ion battery technology but this

time for electric vehicles. It claims to have developed a rechargeable lithium-ion battery with a density

of 400Wh/kg and a range of 300miles. The stinger in this tale is the price: $25,000 for a battery, inflating

the cost of the car considerably.

As with all sagas, the search for longer battery power, will run and run!
