Graphene handles the issues that come with an electrode's lithium moving elsewhere.
Pilots: Um, you want all those lithium batteries in the hold? The European Commission (EC) and the US have pushed back against moves for a wider ban on laptops on aircraft but talks on the subject will continue in Washington next week.…
A new way to put the zinc together makes this safer chemistry an option.
First Alert's CO710 CO alarm is powered by sealed, ten year lithium batteries to provide continuous protection for ten years without battery replacement, and a built-in end-of-life alarm lets you know when its time is up.
Its modern, compact design allows easy tabletop or wall mount placement, and it displays CO levels along with room temp on a backlit display.

The unit's "peak" function captures and allows you to retrieve the highest CO level recorded in your home.
In the event of a CO incident, this valuable information can be passed along to emergency or hospital staff.

The CO710 averages 4.5 out of 5 stars on Amazon, where its list price is discounted 47% to $31.66.

Sean MacEnteereader comments 63 Share this story The Federal Aviation Administration is announcing new air passenger carry-on guidelines. Sadly, though, the authorities are not altering the terrorism-repelling edict prohibiting fliers from carrying on shampoo or other liquids and gels in containers larger than 3.4 ounces. The FAA, however, announced late Thursday that it will still allow you to bring your exploding Note 7 onboard—albeit with a few caveats. Samsung issued a Note 7 global recall last week of the 2.5 million units it had shipped amid reports that the phablet's batteries could explode or catch fire. In response, the FAA said it doesn't want you to use or charge the Note 7 while flying, and the agency doesn't want you to put the device in your checked bags, either. In light of recent incidents and concerns raised by Samsung about its Galaxy Note 7 devices, the Federal Aviation Administration strongly advises passengers not to turn on or charge these devices on board aircraft and not to stow them in any checked baggage. Qantas, Jetstar Airways, and Virgin Australia have issued similar Note 7 advisories. Days ago, a Florida family's vehicle caught fire after a Note 7 left in the Jeep exploded.

They can overheat and possibly explode—under a process known as "thermal runaway"—if they are exposed to increased temperatures, if they have a manufacturing flaw, or are damaged. Earlier this year, a UN agency called the International Civil Aviation Organization barred bulk deliveries of rechargeable lithium-ion batteries on passenger planes. Samsung said in a statement that "We are aware of the Federal Aviation Administration’s statement about the Galaxy Note 7. Consumer safety and peace of mind are our top priority. We plan to expedite new shipments of Galaxy Note7 starting from this week in order to alleviate any safety concerns and reduce any inconvenience for our customers." If you're still in the market for a Note 7, here's our review. For more information on the recall, click here.
