Samsung is working on a graphene battery that charges five times faster
While I have to say that I am not at all complaining about charge times of smartphones, it apparently needs to be faster. Samsung is working on a graphene battery that has more capacity than current batteries and can be charged five times as fast.
The Samsung Advanced Institute of Technology (SAIT) announced this today, reports ZDNet.
Graphene has long been seen as a promising material to replace the current lithium-ion batteries. Samsung Electronics' research arm has successfully synthesized a "graphene ball" that can be used to make lithium-ion batteries last longer and charge faster, the company has said.
According to Samsung, the technology could provide a smartphone battery that is fully charged in 12 minutes. The capacity could also grow by 45 percent. According to Samsung, the battery remains stable up-to 60 degrees Celsius and could therefore also be used in electric cars.
It is unclear when Samsung expects to start mass production of the battery.

Perhaps some of you forgot the Note 7 problems and worldwide recall ...
Samsung lost billions of $ on that.
It makes sense why they want to avoid such problems FOREVER, by investing money into new battery tech which is safe from the always-potentially-dangerous Li-Ion.
Having faster recharge and more capacity is just a bonus to the consumer... but for Samsung it's about not risking their reputation (and money) again.
Current battery tech always have an imposed risk. There are safety measures and decades of experience behind them, so I'd say we're ok with the risks for the benefits.
The actual problem is the stupid trend of making devices slimmer and slimmer. They're making this phone with a huge power hungry display and don't want it to weight anything or be thicker than the last model.
So they fucked up the design and gave the battery no tolerances, witch in turn made it rupture and explode.
Why do phones have to keep getting bigger and slimmer? If I want a big screen I have a tablet, I can't fit a 5'' or more phone on my pocket...

I couldn't agree more. I'm really hating these stupid fads of making things thinner, glossier, and whatever convoluted definition of "more convenient" or "cool" that companies make. If these attributes are a side effect of progress, then I am totally in favor of them. But if I have to make any sacrifices that I did not say I wanted to make, it's stupid.
For example:
Weakening the battery in order to make the phone thinner = bad
Using an OLED display to make the phone thinner = good
Having a shatter-prone all-glass screen wrap around the edge just to remove bezels that my hand or silicone protector is going to cover up anyway = bad
Removing unneeded buttons, switches, and connectors on the edges resulting in smaller bezels = good
Make the screen bigger just to add more pixels = bad
Replace bottom buttons to make the screen bigger = good
Use interpolation to add more camera MP because "moar iz better" = bad
Include a "worse" camera that is actually the resolution it claims to be = good
Removing things like headphone jacks for "simplicity" or "elegance" = bad
Removing things for the sake of water-proofing = good

I consider this to be the Apple effect. Apple sets the trend for the smartphone industry, and they are obsessed with making things thinner and simpler. Other companies follow Apple's lead, putting form over function, to the detriment of consumers. My previous two phones, a Galaxy S6 and Nexus 5, could barely hold a charge and I really wish phone makers would take a different path. I mean, I wouldn't mind a phone that's a bit thicker if it had double the battery life, and I bet a lot of other people would make that trade as well (including iPhone users). One of the reasons why I got a Galaxy S8+ (over the S8) is the larger battery, and this is the first Android phone I've used with has a decent battery life.
New battery technologies are good and all, but my guess is that phone manufacturers would just use it as an excuse to make even thinner phones ("lasts just as long as our previous phone, but is 50% thinner!"). As long as thinness is the primary design goal, we will always see terrible battery life on our mobile devices.

The question we should ask is, Does the battery expand while charging?
