Article: Israeli start-up StoreDot displayed the device - made of biological structures - at Microsoft's Think Next Conference.
A Samsung S4 smartphone went from a dead battery to full power in 26 seconds in the demonstration.
The battery is currently only a prototype and the firm predicts it will take three years to become a commercially viable product.
In the demonstration, a battery pack the size of a cigarette packet was attached to a smartphone.
"We think we can integrate a battery into a smartphone within a year and have a commercially ready device in three years," founder Dr Dorn Myersdorf told the BBC.
The bio-organic battery utilises tiny self-assembling nano-crystals that were first identified in research being done into Alzheimer's disease at Tel Aviv University 10 years ago.
The nano-dots are  described by StoreDot as "stable, robust spheres" that are 2.1 nanometers in diameter and made up of peptide molecules.
The technology has a range of uses,  founder Dr Myersdorf said.
"Batteries are just one of the industries we can disrupt with this new material. It is new physics, new chemistry, a new approach to devices," he said.
The team has also used the nano-crystals in memory chips which could write three times faster than traditional flash memory and as a non-toxic alternative to cadmium in screens.
Dr Myersdorf said that the batteries are likely to be 30 to 40% more expensive to manufacture compared to traditional ones and the final product will be twice as expensive than those on the market today.
But making them should be a relatively easy process.
"It is about letting nature take its course. We just need a facility that can do chemical processing," he said.

Problem: About 300 men in the UK are diagnosed with breast cancer each year compared with more than 45,000 cases for women.
The majority of male breast cancer cases are in men aged between 60 to 70.
Mr Barr, from the Isle of Man, discovered a lump in his breast in July 2006 and a series of hospital tests followed.
The results showed a large and rapidly growing cancerous tumour which meant an immediate mastectomy of the right breast.
"I was in total shock. At the time I didn't even know men could get breast cancer," he said.
"I remember sitting in the hospital waiting room wondering if I was going to die and I thought that I couldn't die because I was only 51."
Mr Barr's surgery was followed by six months of chemotherapy.
"You can have very low patches during chemotherapy when you feel absolutely terrible but you have to remind yourself that it is for the greater good," Mr Barr said.
"I think a lot of men who have breast cancer are very reluctant to come forward because it is a very pink world. It is perceived as a female world and men tend to shy away from that - I feel it is very important that male breast cancer is highlighted."
After contacting a breast cancer support group in the Isle of Man, Mr Barr became part of a network which he has since found invaluable.
"Ten years ago I could never have imagined myself being a member of a breast cancer group but it has given me a whole new perspective, and a whole new social life. It's always funny when we go out together because there is me and about 35 other ladies - a lot of men would be very envious.
"The ladies were more than welcoming - I think they thought it quite novel to have a man as one of their number."
After his mastectomy, Mr Barr found it difficult to come to terms with the disfigurement of losing his right breast.
His doctor recommended regular exercise to aid recovery, but Mr Barr felt self-conscious about going to the gym or swimming pool.
"I thought everybody would be looking at me but it is like everything in this world, people don't really pay much attention.  Psychologically though, I did find this a bit difficult."
Now an active member of the island's breast cancer support group, Mr Barr hopes his experience will help other men be aware that breast cancer knows no gender divide.
"Men need to check their breasts just like women. I would urge everybody to go for regular check-ups just to make sure that everything is OK.
"If you have the slightest worry get it attended to because we all have to be proactive about our health."

Problem: Mr Osborne's newspaper editorial said a so-called "end to austerity" would lead to a "loss of economic credibility".
Earlier Michael Gove, the new environment secretary, said ministers had to listen to public concern about how services are funded.
The Tories need Democratic Unionist Party support to stay in power.
The DUP is committed to lobbying for extra cash for public services in Northern Ireland and promised in its manifesto to "resist any assault" on universal benefits and to maintain the "triple lock" on pensions which Theresa May planned to scale back before the election.
It also opposes the so-called bedroom tax and wants to abolish air passenger duty and cut VAT for tourism businesses.
The Tories lost their majority after Labour leader Jeremy Corbyn, who based his campaign on ending austerity, defied predictions and gained 30 seats.
Former MP Gavin Barwell, who lost his marginal seat, told Panorama Labour had "tapped into" concerns about the impact of years of public sector pay freezes.
Mr Barwell has since been appointed as Mrs May's chief of staff.
Mr Osborne, who implemented deep spending cuts during his six years in the Treasury, abandoned his bid to restore government finances to a surplus by 2020 shortly before leaving office.
His deficit reduction targets have been relaxed by his successor Philip Hammond.
An editorial in the London Evening Standard, which he edits, said: "Talk of 'an end to austerity' is code for 'we're going to allow the deficit to rise, and we don't care'.
"That would risk repeating the mistakes of the past that led Britain to the point where there was, in the words of that Treasury letter, 'no money left'."
It added: "The government already has enough on its plate. A loss of economic credibility would make those problems a whole lot worse."
Mr Osborne, who was sacked as chancellor by Mrs May when she became PM, has repeatedly criticised Mrs May since the election result.
Asked on the Today programme whether the government could change course, Mr Gove said ministers had to "reflect on what the election result told us about the way that people want to see the economy managed in the future".
He said there was a need to ensure public spending was kept at a sustainable level but stressed that "we also need to take account of legitimate public concerns about ensuring that we properly fund public services in the future".
Speaking on the BBC's Daily Politics, Tory MP Dominic Grieve said austerity had been a necessity after the 2008 financial crash, but warned against it becoming "a state of semi-permanence".
He said the government should not be "chucking billions of pounds at public services" and said "turning the tap on" on public spending could undermine wealth creation.
But he added: "The question is have the limits of reasonableness been reached with the electorate."
