Researchers “heal” destructive dendrite growth in lithium-metal batts

One of the biggest killers of battery life is the shorting within the battery (blistering & possible fire). These are often caused by excessive drain and re-charge cycles as the heat created allows the formation of dendrites as well as gases.

Here's a good writeup of an interesting way to combat the growth by pushing the current in the battery as a short pulse!

The way you charge your phone is increasingly coming under question, especially with the increased prevalence of wireless chargers, more people are charging their phones for longer, and more frequently. (Honestly I think that's part of the reason for Apple's batterygate issue, they could well have been trying to control peoples charging habits as well as battery discharge rates)

It'd be really cool if we could make batteries more efficient by just changing the way chargers work.

That's the idea of Quick Charge 3.0 by Qualcomm. Control the way the charger works so the battery can last longer yet charge fast.


@avanteguarde And it definitely works. I'm not going into the details but my old phone (QC 1.0) Vs. my new phone will actually charge faster under some conditions, I presume because 3.0 was designed more on a focus of preservation of the batteries.


@avanteguarde & @pccheese - This technology is so new I doubt you'll find it in any batteries/devices yet.


@danj I don't know... Qualcomm always seems to be on the cutting edge of it all. I wouldn't doubt they're on the cutting edge on charges too considering that the QC platform is the fastest charging non-proprietary charger around.


@danj Read about Quick Charge 3.0.

Also, all new LG and HTCs have incorporated it.

Here is a device list.

@danj I just re-read this article from arstechnica you linked.

Is this legitimate?

You realize it mentions Li-Li... DiLithium... ??!!

Doesn't the Star Trek's Enterprise use DiLithium crystals to power its warp engines?!

Yes, a slip of the tongue ;-} And you get DiLithium. Surprisingly the original Star Trek was based on what was technically possible, just not real at that time point! There are a few creative licenses with naming and the transporter and warp drive is straight fiction.

When I was going to school we would get together to watch on a brand new projection TV we had gotten in the student hall to watch the re-runs our local TV station was showing (this is back in the late 1990's) on Saturday night.

We had bets on what was the most likely to be real in 10 and 20 years. Some of our guesses did come true! Small floppy discs, high density storage and a much improved TV standard from what I remember. We thought we would have visited all of our solar systems planets but we missed on that! It's only three years ago we visited Pluto with a robotic space traveler not a real human!
