Why does an e-cigarette Explode? How can We Prevent It?

Here are some brief history of notable e-cigarette explosions and fires in this year:
Sneads Ferry, North Carolina, January 2014
A North Carolina man who spent over 20 years working as a firefighter was injured after his e-cigarette exploded in his face. He described the incident to theJacksonville Daily News as feeling like "a bunch of hot oil hit my face." After spending the night in the hospital, the newspaper reported that he continues to suffer from the incident: "The bottom of his left eyeball is sensitive to light, hard to see out of, and will need to be looked at by an optometrist."
Springfield, Missouri, January 2014
Last Christmas Eve, Chantz Mondragon was sitting in bed with his wife when his e-cig overheated and burst into flames. The device was charging via a USB port on his laptop. He described the explosion as "a searing hot blinding light like a magnesium sparkler, [like] whenever you see a person welding." Mondragon also said the fire burned through his bed, and caused second-degree burns on his leg and foot.
North Yorkshire, England, April, 2014
Eighteen-year-old Laura Baty was serving a customer at the Buck Inn Hotel when her coworker's charging e-cigarette exploded behind the bar. "I started crying hysterically and my arm was all black," she told the Press. "My dress caught on fire as I ran away, and I just didn't know what was happening."
London, April 2014
A woman who used an incompatible charger to charge her e-cigarette caused a major fire that took about 40 minutes to get under control, according to the London Evening Standard. A member of the London Fire Brigade told the paper that, "As with all rechargeable electrical equipment, it's vitally important that people use the correct type of charger for their e-cigs to prevent fires which can be serious and could even result in death."

 These explosions are so terrible.How can we prevent it?

Specifically, it's e-cigarettes' lithium-ion batteries that combust. These batteries are also found in laptops and cellphones. But with e-cigarettes, the batteries are especially prone to overheating because smokers use incompatible chargers,overcharge the e-cigarettes, or don't take sufficient safety precautions. For example, many e-cigarettes are made to plug into a USB port, which smokers may take to mean the devices can be safely charged with a computer or iPad charger. But if left too long in a common USB port, some e-cigarette batteries can fry.
When you charge them, they are 99.9 percent safe, but occasionally there will be failures.
Now we have a USB charger will keep you safe when you used the unsuitable charger.
