First and foremost, silver-zinc can offer up to 40 percent more battery life than traditional lithium-ion batteries and 200 + cycles at 100% discharge. ZPower claims that their product contains no toxic chemicals and is up to 95% recyclable—which I would assume means that they have addressed the problem of mercury leakage that plagues silver-zinc batteries at the end of their life-cycle. They also noted that the batteries feature a water-based chemistry that is completely non-flammable (unlike lithium-ion that has a reputation for the occasional explosion). The one major drawback of silver-zinc is the cost of the silver itself, but word is that ZPower is planning on a trade-in recycle policy that will help to offset costs. Sounds good, but we will have to wait and see if the notebook coming out next year will be important enough and affordable enough to drive sales.

Dr. Ross Dueber to Discuss First Silver-Zinc Battery
for Mobile Consumer Devices at Batteries 2008 in Nice

CAMARILLO, October 7, 2008 – Dr. Ross E. Dueber, president and CEO of ZPower, Inc., will discuss the industry’s first silver-zinc battery technology for consumer electronics at the Batteries 2008 conference in Nice, France, starting October 8th. His presentation will address the performance, environmental, and safety advantages inherent within ZPowerTM silver-zinc batteries, scheduled to launch in a major notebook computer in 2009. The annual event will be held at the Acropolis Convention Centre on October 8, 9, and 10. Batteries 2008 is a worldwide exhibition focused on power supply, with more than 400 attendees.
Dr. Dueber will discuss the next replacement for lithium-ion rechargeable batteries and what power source can take mobility into the future. “At the heart of the $55 billion global battery market is the chemical conundrum of power supply,” said Dueber. “Today’s consumer has the ability to watch an entire movie on a palm-sized device—but portable power technology has not kept up. Engineers admit that they are hitting the wall on lithium polymer and lithium-ion performance. Unstable lithium-ion batteries have resulted in a high number of product recalls by manufacturers of notebook computers. These market trends are creating a pressing need for a better battery.”

Silver-zinc battery chemistry is currently poised to move into the commercial marketplace for use in consumer electronics. This new silver-zinc battery chemistry uses the latest in advanced polymers, nano-technology, power electronics and processing methods to create a battery that surpasses other rechargeable batteries for notebook computers, mobile phone and consumer electronics applications.

The advantages of silver-zinc batteries can be summed up as follows:

High Performance – Up to 40% more run time than traditional lithium-ion batteries. And with recent improvements in battery cycle life, silver-zinc batteries achieve 200 + cycles at 100% discharge and thousands of cycles at intermediate discharge.

Clean Technology – Over 95% of key battery elements can be recycled and reused. The raw materials recovered in the recycling process of silver-zinc batteries are the same quality as those that went into the creation of the battery. Environmental impact is lessened since the need to mine for new materials is minimized.

Safe – Silver-zinc batteries contain no lithium and are inherently safe. They are not subject to the recent FAA air travel restrictions now placed on lithium-ion batteries. Silver-zinc batteries feature a water-based chemistry that is not flammable. The battery is therefore free from the problems of thermal runaway and fire.

PANASONIC ANNOUNCES EVOLTA — THE WORLD'S LONGEST LASTING AA ALKALINE BATTERY IN MORE DEVICES*

Performance of New Battery Recognized by Guinness World Records™

SECAUCUS, N.J. (September 24, 2008) – Proving that there is still room to enhance the performance of everyday batteries, Panasonic today introduced the EVOLTA battery, which is recognized by Guinness World Records™ as the world's "longest lasting AA alkaline battery cell" in more devices.* The recognition was the first of its kind for Guinness, which created a new category for batteries. The EVOLTA AA Alkaline battery lasts longer in more devices than the company's own previous-generation AA alkalines as well as those from other brands.

Demand for batteries that will meet the needs of today's more energy-efficient products is increasing. To address this need, the EVOLTA battery, which derives its name from "evolution" and "voltage" to symbolize growth and power, was specifically designed to work with a variety of electronics devices, ranging from low-middle-drain remote controls, portable radios and MP3 players to high-drain digital cameras and remote-control cars. EVOLTA is not just tailor-made for one device, but allows for outstanding performance across a broad spectrum of applications.

The new structure of the EVOLTA battery provides more internal space than Panasonic's previous generation batteries, allowing storage of extra active materials and incorporating an improved sealing technology, creating a more durable battery. Newly-developed active materials for the battery's cathode (manganese dioxide and oxy-hydroxide titanium) and anode (zinc) facilitate a chemical reaction that delivers superior performance. To maximize the chemical reaction within the battery, Panasonic has improved the manufacturing process to pack active materials more evenly and densely.

Battery testing followed industry-standard protocols issued by the American National Standards Institute (ANSI) and the International Electrotechnical Commission (IEC). The test results reveal that EVOLTA batteries deliver excellent performance in wide ranging equipment from low-current applications such as TV remotes to high-drain applications like digital cameras.

To further support its AA battery claims, Panasonic also conducted device testing and results of those tests include:

* A digital camera powered by EVOLTA batteries took 272 shots compared with 209 shots when powered by Panasonic's current Alkaline Plus batteries — an increase of 30%. **
* An FM radio played up to 14 hours longer when powered by two EVOLTA AA batteries than when powered by Panasonic's current Alkaline Plus batteries.***
* A remote-controlled car traveled as much as 8.7 miles farther when equipped with six EVOLTA AA's than when powered by Panasonic's current Alkaline Plus batteries.****

"I believe that EVOLTA is the ultimate power solution for any and all consumers that will enhance everyday life by delivering superior portable energy solutions," said Matt Sora, vice president of sales and marketing for Panasonic Battery Corp. of America.

To demonstrate the power of EVOLTA, Tomotake Takahashi, an engineer in Tokyo, created a mini robot nicknamed "Mr. EVOLTA." The 6.7 inch-tall robot made headlines in May when it climbed a 1,740-foot rope dangling from a cliff in Arizona's Grand Canyon National Park. Mr. EVOLTA accomplished the feat using just two AA EVOLTA batteries. The climb took 6 hours and 46 minutes and covered a distance that was 290 feet more than the height of Chicago's Sears Tower, the tallest building in the U.S. Click here to download photo of Mr. Evolta.

"EVOLTA was launched in Japan in April and is currently enjoying tremendous success," Sora noted. "We expect that EVOLTA will also be favorably accepted by consumers in the U.S. market."

The new EVOLTA batteries will be available in stores in October. AA and AAA batteries will be offered in four-packs and eight-packs. The suggested retail prices are:

* AA or AAA four-pack, $4.99
* AA or AAA eight-pack, $8.99

Sweepstakes

To promote the battery, Panasonic is launching the EVOLTA Sweepstakes promotion. From October 1, 2008 through March 31, 2009 consumers can enter for a chance to win a variety of Panasonic products with a total value of $25,000. The Grand Prize winner will receive a 42-inch Panasonic VIERA plasma HDTV and a Blu-ray Disc home theater system.

Thirty other prizes will be awarded in all, including 5 Panasonic VIERA plasma HDTVs, 10 Blu-ray Disc players and 15 LUMIX digital still cameras. No purchase is necessary to participate in this sweepstakes.

According to their findings, EVOLTAs have a 10-year shelf-life—which is nearly double the duration of other products on the market. Panasonic's EVOLTA batteries will also keep gadgets running up to 20% longer than offerings from Duracell and Energizer—as well as their own Oxyride brand. Unfortunately, US residents are going to have to wait until sometime later this year to get their hands on the product—but Japanese customers can power up starting on April 28th for about $5.40 for a pack of four.
