Next question. What is electrolyte decompostion? Dispose of it properly see below and buy a new one. How to Dispose of Puffed Lipo Batteries The proper way to dispose of a swollen lipo battery is the same as what you would do when you throw out any old battery. Tips to Avoid a Swollen Battery Proper charging — Make sure you charge your battery properly using a quality battery charger.

For safety, make sure you put your batteries in a lipo bag while charging. And after you are done charging them, give them a little time before you use them. Proper storage — Do not store your batteries in a hot location. Mike Edmonds April 24, at pm Reply. Eric July 29, at pm Reply. Ted September 13, at pm Reply.

LiPo batteries can be found at a variety of places locally or even online at Amazon. You can find some of the best sellers on Amazon by clicking here. If you want to see what happens when a LiPo puffs up and is not replaced check out the video below.

It is about the 30 second mark when you can see the dangers of swollen LiPos. Even when your battery is not abused, merely using your battery every day will naturally generate gas by a process known as electrolyte decomposition. If you overheat or over-discharge your battery, the process of electrolyte decomposition happens even faster. A LiPo battery is composed of three things: the anode, the cathode, and the electrolyte. The anode and the cathode are the positive and negative terminals of the battery.

The electrolyte, on the other hand, is a chemical inside the battery that ensures that charged ions can travel from the anode to the cathode in the discharge process and from the cathode to the anode in the charging process. Electrolyte decomposition occurs as the electrolyte breaks down chemically. In a LiPo battery, therefore, as the electrolyte breaks down, what you have at the end is lithium and oxygen.

Depending on whether you are charging or discharging your battery, this makes lithium oxide on the anode and cathode. They are prone to mechanical damage, catching fire, and premature battery swelling.

Caring for your LiPo battery takes a little more care than your typical lithium-ion battery. They should be kept cool, stored in partially charged state, and protected from physical damage.

Once your LiPo battery swells, the best advice is to stop using it as soon as possible. You will also need to replace it soon, as a swollen LiPo battery probably cannot hold much of a charge. Remember to follow proper battery disposal practices once you decide to discard your spent LiPo battery.

But molecular oxygen itself is not a flammable gas, O2 is a highly reactive gas, one which when combined with a fuel source and energy, might result in rapid oxidation and an exothermic reaction, … or, combustion … fire. I am not speaking to the veracity for the component gases resultant from any specific type of Lithium Ion battery failure, only that your statement is incorrect; seemingly in the misinformed assumption that gases containing an oxygen within their molecule are therefore deemed flammable.

But pure oxygen gas only reduces the amount of energy input needed to kick off the flame producing oxidation reaction of combustion; coincidentally of which, the fire has a primary reaction component being none other than carbon dioxide, which itself is sometimes used in fire suppressant systems as an oxygen diluent, lowing the reaction potential of the oxygenation component, O2.
