Amid lakhs of recalls of notebook PCs with Sony rechargeable batteries, Zinc Matrix Power Inc. has announced a technology that could make portable computing safer. The new battery technology is based on silver, zinc and water.

According to the company, this technology contains no lithium or flammable liquids, and has no problems of thermal runaway, fire and danger of explosion. Additionally, these batteries are free from Li-ion battery regulations that limit the size of Li-batteries on airplanes.

Compared to traditional Li-ion batteries, said Zinc Matrix Power, batteries based on its silver-zinc technology offer three advantages. "First of all, the inherent chemistry of our batteries—based mostly on silver, zinc and water—is safer," said Dr. Ross Dueber, president and CEO of Zinc Matrix Power. "Secondly, these high-energy batteries can significantly improve upon the performance of existing Li-ion batteries used in notebook computers and cellular phones. And finally, Zinc Matrix Power uses an environmentally friendly chemistry which allows battery cells to be recycled and the contents reused."

Aside from intrinsic safety offered by ZMP cells, the company shared that a notebook PC battery pack using ZMP cells can provide longer run-time than equivalent Li-ion based battery packs. The combination of longer run-time, safety and an unrestricted pack capacity unlike Li-ion battery regulations for in-flight use make Zinc Matrix Power battery cells an alternative for notebook PC OEMs, the company added.

Aside from notebook computers and cell phones, the new battery technology can be used in various applications in the military, government, retail and broadcast markets.

Zinc Matrix Power batteries will be available for evaluation and testing in early 2007. The new battery technology is being demonstrated at this week's Intel Developers Forum in San Francisco, California.
