Blast-proof batteries invented

Ionic Materials Ever since its inception in the 1990s, Lithium-ion batteries have been the prefered choice of manufacturers, finding their way into a range of portable devices that require a rechargeable power source.
Applications have ranged from powered banks that propel vehicles to slivers of battery that are used in slim smartphones. However in recent years, it is clear that liquid Lithium-ion technology is quickly becoming outdated and is struggling with sustaining the pace of today's fast-moving technology sectors, especially the smartphone market. The push to pack devices with higher capacities and make them last longer have led to rampant cases of unstable batteries. These last several months have especially witnessed high-profile cases of batteries exploding either due to being faulty, punctured or damaged.
Michael Zimmerman of Ionic Materials, an expert in polymer innovation and semiconductor packaging, has spent the last four years developing a possible solution to power hungry devices. The result is the first solid lithium polymer battery that will never explode even if you literally take a hammer and drive a nail through it.
The new generation of batteries use flexible polymer packaging that enables the units to be used in unconventionally shaped molds.
The endeavour was possible owing to a $3 million contract granted to Ionic Materials by the United States Department of Energy. “My dream is to create the holy grail of solid batteries,” said Zimmerman. He plans to build a consumer version of the product within the next two years.
Unlike other electrical technologies such as processor or even storage, the rate of innovation in the battery space has significantly lagged. Even as far back as across the past 150 years, the number of battery technologies that have been assimilated into mass production are barely in the lower single digits. From lead acid, to zinc-carbon, to nickel-cadmium to lithium ion, the capacities as well as recharge characteristic improvements have not been dramatic.

Liquid-based Lithium-ion batteries had caused quite the commotion over the past year - anyone familiar with Samsung will know that their flagship smartphone - the Note 7 - didn't quite bring in the revenue and more importantly the reliability that the company expected. On the contrary the company reported a loss estimated to be about $5 billion, all due to the faulty batteries used in these flagship devices. Since the first report of the smartphones exploding, Samsung has launched its own investigation into the matter. Unfortunately the company was unable to locate the precise cause of the combustible batteries but experts believe that a safety defect caused the two electrodes to internally touch one another, causing the batteries to overheat and explode.
