Battery With Inbuilt 'fire Extinguisher' Developed by ritababe(f): 4:26pm On Jan 16, 2017 |
Researchers have designed a lithium-ion battery that contains a fire-extinguishing material, which is released if the battery gets too hot. Flame retardant triphenyl phosphate (TPP) sits inside a shell within the electrolyte fluid. The shell melts when the temperature reaches 150C (302F), releasing the chemical compound. In tests, battery fires were extinguished in 0.4 seconds. Lithium-ion batteries power many devices but are a known fire hazard. The Stanford University research team's peer-reviewed paper has been published by the journal Science Advances. Previous attempts to incorporate TPP inside batteries without the shell have hampered their performance. If a lithium-ion battery cell charges too quickly or a tiny manufacturing error slips through the net it can result in a short circuit - which can lead to fire. In February 2016, the US National Transportation Safety Board issued a warning about lithium batteries in aeroplane cargo, describing them as "a fire and explosion ignition source". While Samsung has not yet released the results of its investigation into what caused some of its Galaxy Note 7 smartphones to catch fire last year, local reports have suggested it has found that the batteries were responsible . However, the firm would not confirm that this was their conclusion. "We understand the need for answers and appreciate your continued patience as well as that of our valued customers, partners and stakeholders," it said in a statement. "We are working diligently to ensure that we have a comprehensive update and will provide more information in the coming weeks once we have the final report." Better batteries Battery technology has been slower to evolve than the many battery-powered devices that rely on it, said Ian Fogg, senior analyst at IHS, "There is enormous pressure to improve battery tech. It's one of the areas that's holding back mobile devices and a range of other products," he told the BBC. "Manufacturers have been balancing out consumer demand for longer-lived batteries, and more powerful devices with better graphics and larger more detailed displays, with the sophistication of battery tech. "It's very difficult to push up the capacity of batteries and there is always a risk that a battery in any device could fail." http://www.bbc.com/news/technology-38637357 cc. lalasticlala 1 Like 1 Share |

I remember once when my dad gave me money to pay the electricity bill but instead i bought a lottery ticket for a brand new car. When i got home,i explained to my dad what i did and he beat the crap out of me. But the next day,when my dad woke up and opened the door,outside my house was a brand new car. We all cried especially me,because the car was from the electricity company,they were there to cut off the electricity, my dad beat the crap out of me again 4 Likes |

Once upon a time in a village, a man appeared and announced that he would buy monkeys for N100 each. The villagers seeing that there were so many monkeys around, went out to the forest and started catching them. The man bought thousands at N100 and as supply started to diminish, the villagers stopped their efforts. He further announced that he would now buy at N200. This renewed the efforts of the villagers and they started catching monkeys again. Soon the supply diminished and people started going back to their farms. The offer rate increased to N250 but the supply of monkeys became so little that it took much effort to even see a monkey, let alone catch one. The man now announced that he would buy monkeys at N500! However, since he had to go to the city on some business, his assistant would now buy on his behalf. In the absence of the man, his assistant told the villagers: ''Look at all these monkeys in the big cage that my OGA has bought from you, I will sell them to you at N350 and when my OGA returns from the city, you can sell it to him at N500''. The villagers squeezed out all their HARD EARNED savings and bought all the monkeys. The most greedy ones among them even sold their lands to purchase many MONKEYS, hoping to make a huge profit without labor. Then... They never saw the man or his assistant. Only monkeys everywhere! Welcome to #MMM. The world of Monkeys 1 Like |
