We know that heat and Lithium based batteries don't mix but there is more to worry about than catastrophic failure. A post over at Hack a Day illustrates the consequences of heating a Lithium based battery with 1% or less charge, the complete and permanent death of the batteries ability to hold a charge. There are some uses for these batteries in designs which can trap heat near to the battery and not properly transfer it out and it is apparently very important to keep those batteries at least moderately charged. If you are making something which might expose the batteries to excess heat ensure you monitor the charge to prevent having to replace the batteries. The complete discharge of a Lithium cell is never a good practice and this illustrates another reason to keep those batteries charged.
"There’s a million ways to kill a battery, and lithium batteries are known not to like being completely discharged, but it looks like the combination of deep discharge and heat is entirely deadly. Now you know."

By “completely discharged”
By “completely discharged” they are referring to the draining of the cells below their initial cut off point – the point where consumer electronic devices tell you that the battery is at 0% and needs to be recharged. In actuality there is usually another 10 or 15% left as a ‘buffer’ to prevent damage to the cells.
I once removed the tiny logic board on a Lithium Ion pack to access that reserve power after my device went dead. Not sure I’d do that again though.
The circuitry on these Li packs are designed with this in mind – to prevent deep discharge and failure – so 0% is never really 0% and therefore no real need for concern. Still, its advised to always charge before storing for long periods.
Isn’t this, like, applies
Isn’t this, like, applies ONLY to Lithium-Polymer ones? Lithium-Ion batteries should be fine, I think.
Li-Po is a highly confusing
Li-Po is a highly confusing term. Originally it meant a true polymer electrolyte, but today it mostly means a normal li-ion battery in a polymer casing. In some cases the liquid electrolyte is in a gel, confusing the term polymer even more. Wikipedia has a nice page about it.
That’s stupid. Lithium-Polymer and Lithium-Ion are absolutely two different things at their core. They’re physically different inside. I never ever heard or read for someone out there to call a Lithium-Polymer as a Lithium-Ion one, where there hell did you got that gibberish from?
quote: “With gelled electrolyte added, what is the difference between a normal Li ion and Li ion polymer? As far as the user is concerned, lithium polymer is essentially the same as lithium-ion. Both systems use identical cathode and anode material and contain a similar amount of electrolyte.”
That’s even more stupider. To
That’s even more stupider. To say “Lithium-Ion Polymer”, that is. Because there’s no such thing. It’s EITHER Polymer OR Ion. It can’t be “Polymer Ion”.
Stupid GameNeck! Any atom can
Stupid GameNeck! Any atom can be made into ion, some more easily than others and Polymers are just long chains of identical molecules(molecules can be made up of many different atomic elements)! So the lithium(ionized atoms, unionized atoms) are embedded in the polymer chains! Lithium is very reactive to water so the Polymer is made of other molecules that support Lithium’s easily ability to be brought into an ionized state(charged). Did you even take the time to read the links provided and learn, oh I guess not because you make a fool of here yourself regularly!
Hay Einstein, Google battery
Hay Einstein, Google battery chemistry and see where ions come in!
“Batteries convert chemical energy directly to electrical energy. A battery consists of some number of voltaic cells. Each cell consists of two half-cells connected in series by a conductive electrolyte containing anions and cations. One half-cell includes electrolyte and the negative electrode, the electrode to which anions (negatively charged ions) migrate; the other half-cell includes electrolyte and the positive electrode to which cations (positively charged ions) migrate. Redox reactions power the battery. Cations are reduced (electrons are added) at the cathode during charging, while anions are oxidized (electrons are removed) at the anode during charging. During discharge, the process is reversed.”(A)
No matter the element used for the Ion’s it’s ions that are intrinsic to a battery’s functionality! Master Chen did you graduate from high school, and if you did you must been socially promoted to get you out of the teacher’s/school’s hair!
