Ion batteries are used in cars and many electronics. When batteries overheat or are exposed to high temperatures they can explode or cause a fire to occur. This can happen as a result of the electronic eg. laptop or tablet is used very often and subject to constant recharging or exposed to extreme temperatures.  Separators is a term used to describe electrical insulating material that enable lithium-ions to go back and forth in the batteries electrodes. The tiny openings within the separators then close off the batteries current when this occurs preventing the batteries from overheating. There are times when a battery can overheat and the separator is unable to stop it from doing so, thus subjecting the separator to melt or decompose. Newer separators contain polymers that close the current and another polymer that stabilizes the separator so that it does not breakdown or decompose quickly. This means that a separator will close off heat exposure and contain it at 130 degrees celsius and will prevent shortage or battery explosion up to 190 degrees celsius.

People travel with their mp3 players, laptops, tablets and most of all cell phones.  The weather is changing due to earthquakes, tornados, floods and other disasters that have had an extreme effect on our earths temperature overall.  When these events occur, they subject the earth to shift or move in that our climate gradually leaps past seasonal occurence such as snow or rain and when this happens water shortage or drought is of result because the areas subject to such damage shifted and thus weather that is normally expected did not occur.  Electronics have become our everything because they are used to wake up to, remind us of things, work, play games, listen to, talk, message and watch. Heat occurs while these electronics are on, charging and are stored away or left in the light or sun for long periods of time.

IDEA

Products and electronics that contain lithium ion batteries need overheating sensors or battery distress indicators included in the software to warn the user that the electronic item will now be shut off to avoid battery explosion or damage to person using them.  This should not be seen as advertising that such an item was manufactured defectively because it was made by laborers who are underpaid "even by their countries standards" or go without very much sleep and somehow that good old quality check was done halfway like the living conditions people with low incomes are subjected to; which resulted in a faulty product doomed for explosion once turned on during a hot and humid sunny day.  If the software within the electronic item whether it be an mp3 player, tablet ect. could indicate to the user that the battery is in distress and therefore trigger an auto-shutoff this will not only save the owner or user from bodily or physical harm by fire to other things as well but it will indicate to the user that there is something wrong due to extreme heat, overuse or otherwise. Once it is shut off this will allow the electronic product you are using to cool down before you turn it on again to see it is working properly. Don't be the one to start the campfire, or cause everyone to leave the job minus a days pay- software that includes the battery distress indicator is needed!
