Smartphone Technology: Latest Battery that Can Triple Your Smartphone Battery Life

The battery barons of Stanford have done it again. Led by Yi Cui, the team has created the so called “Holy Grail” of the Li-Ion battery design.

To be more specific, they have finally discovered the way to create and develop a rugged lithium electrode that has the capability to increase the lithium-ion battery life up to four times.

The rugged lithium electrode can increase the battery life of your mobile phone for up to three times as well as reduce the cost and size of the electric cars battery pack.

Battery Capacity

The capacity of a lithium-ion battery is largely dictated by the amount of the lithium ions sucked into the anode while charging. Almost all lithium-ion batteries these days are made with graphite. This material is long lasting and relatively cheap and keeps its capacity over a hundred discharge and charge cycles.

However, the useful capacity of graphite is low. Lithium is currently the best anode material available. But, it can potentially explode when it comes into contact with electrolyte. If this issue can be rectified, the lithium-ion battery can have a higher capacity.

A New Approach with Nanotech

nanotubes stanfordYi Cui and his team at the Stanford University have found the newest approach to creating lithium anodes that could make the battery’s capacity more than 150 discharge and charge cycles and not explode. The battery barons of the Stanford University are responsible for a huge number of battery breakthroughs that people have come over.

Like the other battery breakthroughs, the nanotechnology is the key to develop the new lithium electrode. Lithium tends to expand dramatically when it has absorbed ions while charging. As it expands, cracks are created in the metal. The lithium ions can ooze out from these cracks and from dendrites or mossy metal deposits.

The dendrites can lower the lithium-ion battery efficiency that’s why it becomes useless after it has reached its maximum charge/discharge cycle.
Stanford battery barons have placed a layer of carbon nanosphere on the surface of the lithium anode.

The layer of carbon nanosphere can prevent the cracks on the metal and avoid dendrites from forming. These nanospheres can create a series of interconnected domes strong enough to keep the structural integrity of the lithium-ion battery. This also allows the ions carrying electricity to pass back and forth into the anode.

To be more specific, the layer or carbon nanosphere is a protective layer about 20 millimeters thick. This prevents the battery from reacting explosively with electrolytes.

More Efficient Batteries

The Stanford lithium-ion battery can have 99% coulombic efficiency even after 150 charge/discharge cycles.

Yi Cui was quoted as saying that this is short for the 99.9% required for a commercial viable design. And although they are not at 99.9% threshold yet, they are very close to it.  By making significant improvements to their previous designs they are certainly getting there with both new electrolytes and additional engineering,

The Cui team can realize a lithium-ion battery design that can power Smartphones three to four times longer than the current Li-ion batteries available today.
The new lithium anode not only powers smartphone and electrical vehicles up to four times, but also creates a small, compact battery.

Mac versus PC – The War Continues

Mac versus PC – The War Continues

mac laptop

If you own a home computer you probably know that there are really only two flavors.

Mac and PC.

The PC has rules the roost for many years, with windows being the operating system we all know and …love?

If you work with computers in your office, chances are you have a PC. At least, that used to be the case.

These days things are changing and companies are letting Macs into their offices and are running them all with joy, at least in some cases.

Although what is also interesting is that Mac only really makes up a small percentage of the market, some say around 5%.

Let’s take a look at the main differences between the Mac and the PC.

Main Differences

Although the output of these computers are almost the same, how they work and look is a huge thing.

Appearance

If you have seen the Mac around since it was first on the market in 1984, you will know that one of the main differences is how they look.

Some of the earlier macs had striking colors, and these days with the whole mac range, they have settled on a brushed Aluminium look that many of the phones also use.

If you are a fan of design, then the Mac certainly wins out here!

Price

Macs have always been on the premium side, which kinda goes along with their sexy image.

The prices are often far more than a PC, with many claiming that a great device costs a lot of money.

Many would argue against this and say you only need to pay for what you need. In which case the PC often wins.

And now that PCs often come with Android installed or use a very simple setup, the are also very cheap.

Technology

Macs used to run on very different technology but a few years ago they teamed up with Intel and started using the same chips as in PCs.

So in this sense, although the Macs are very different, on the inside they are often very similar.

So when it comes to tech, the only major difference is that the macs have their own connector type which has very fast transfer speeds – the lightening connector.

Manufacturing

Perhaps one of the reasons that Macs are so expensive is that they control everything.

From the manufacture of the computers to the integration of the software.

So although there is a lot more variation in PCs, the quality of the Macs can be higher because they are in complete control.

Operating Systems

It all falls back to the main difference between these two computers and that is the OS, or Operating System.

PCs are based on DOS which became Windows and has continued like this until today.

Mac OS is based on Linux, a server based system, that is very robust and easy to maintain.

They have built their own interface on top to make it super user friendly and reliable.

Software

One of the downsides of the control imposed my Apple is that there is far less software choice when it comes to Macs.

Although there are always the fundamentals (photos, office tools etc) many of the more niche products and games only come out on PC. Or PC first.

So when you are considering a PC or Mac, you need to keep this in mind.

Security

Of course this tight control also comes with a major plus and that is security.

PCs are attacked constantly and many people do not even know they have a virus or malware installed on their machines.

But with a Mac this is very uncommon and they have their own software already installed to protect you.

Summary

Choosing between a Mac and PC is not an easy choice with so many factors to consider.

But we hope that this article has helped you get a feel for the main differences and how they affect you.
