Matsushita Touts Spark-Resistant Batteries

One of the tenets of capitalism is that businesses and manufacturers will quickly jump on any marketing and sales opportunity they believe is viable—and if they’re successful, they can quickly lock down a major portion of a market. Following that idea, Matsushita—which is the parent company of the consumer electronics brand Panasonic—announced today (Japanese) that it has boosted its production capacity of spark-resistant batteries from 100,000 units a month in April 2006 to five million units per month now, filling thhe market and confidence gap left in the wake of rival Sony’s recent 10 million unit battery recall, as well as smaller-scale recalls from Sanyo.

Matsushita’s batteries include heat-proof layers which insulate the battery cell, adjacent to an existing separator which insulates the battery’s anode and cathode. If that separator is punctures or compromised—perhaps by foreign matter introduced during manufacturing—a battery can overheat and even catch fire. Matsushita says that with its new insulating layer, the battery won’t overheat even if the battery short-circuits.

Matsushita’s batteries will be available in bulk to manufacturers, rather than to consumers directly. The company says it hopes to first bring the insulated design to lithium-ion notebook computer batteries, and intends to deploy the technology in half the lithium-ion batteries it produces by 2009.

Matsushita currently produces about 15 million lithium-ion batteries a month for notebook and 10 million lithium-ion batteries for cell phones, and accounts for about one eighth of the global lithium-ion battery market.

This new Windows 10 feature promises better battery life and less fan noise

Microsoft is working on a new feature that can help tune the performance of your PC's processor for both better battery life and reduced fan noise. Known as EcoQoS, it's now in beta testing with Windows Insiders and promises to make Windows 10 a lot more efficient.

According to Raymond Li, program manager for Windows Fundamentals, this new EcoQoS feature is about better energy consumption and reduced power and thermal throttling. It's all accomplished with what's known as a new "quality of service level" inside Windows 10, which works better with certain background processes that do not have a significant performance or latency requirement.
