The lithium-ion battery also has a risk of degradation due to aggressive and unsafe combustion reaction in the event of mistreatment. This reaction can take place when the battery temperature goes beyond 65 ° C and is very probable at over 75 ° C.
In the event of a battery fire, hydrofluoric acid is formed and released by the thermal decomposition reaction of the anion PF 6 - of the electrolyte contained in the battery. An INERIS report on the batteries of electric cars specifies this risk.
Furthermore, the INERIS studies show at the moment that: "From a metrological point of view, the measurement of fluorinated compounds produced in the event of the fire remains a delicate operation." The concentration of hydrofluoric acid formed is therefore variable and depends above all on the quantity of electrolyte in combustion and on the combustion temperature.
Other toxic gases (mainly carbon oxides) are formed during electrolyte combustion (combustion of ethylene and propylene carbonates). To prevent the battery from leaking or burning, the lithium-ion battery must be handled with extreme caution.
If a leak of electrolytes is observed from a lithium-ion battery, the liquid may contain hydrofluoric acid. It is necessary to absorb the liquid residue that comes out of the battery through a suitable absorbent like the absorbent that neutralizes the acidic chemicals ACICAPTAL or the TRIVOREX polyvalent absorbent. It is advisable to wear personal protective equipment.
In the event of dermal or ocular exposure to liquid from a lithium-ion battery, a severe chemical injury may be generated. Decontamination suitable for the danger represented by hydrofluoric acid is required. It is recommended to consult a doctor urgently. In general, lithium-ion batteries in cars are isolated and protected so that, in the event of combustion, they do not let out hydrofluoric acid vapors. In the event of a traffic accident, if the battery catches fire, do not, as far as possible, come into contact with vapors that may leak.
In the case of dermal or ocular exposure to products deriving from the combustion of lithium-ion batteries, decontamination suitable for the danger represented by hydrofluoric acid is required. It is recommended to consult a doctor urgently.
What Action Makes Your Lithium-Ion Battery Dangerous?
And it is precisely that of temperature one of the aspects that, to date, constitutes a disadvantage or, at least, a risk factor for lithium batteries; since lithium is, in fact, a dangerous and flammable metal, exposure of the battery (and therefore of the device) to high temperatures makes them particularly prone to explosions.
Sun and heat can be considered the worst enemies of lithium accumulators because they consistently contribute to accelerating their natural aging. Therefore, if leaving a battery attached to its battery charger for an excessively long period in it does not present any particular problems with its recharging, the same cannot be said about any sudden changes in current or short circuits, situations that can seriously undermine them.
Integrity Another limitation of lithium batteries is the need to be used often; they stay healthy if they are used frequently.
However, it should be considered that lithium-ion batteries can be used even months apart; while losing part of their potential, excessive non-use does not lead to an excessive loss of considerable charge, whereas traditional batteries, if not used for the same period, even lose 50% of their charge. Due to their structure and composition, one of the significant disadvantages of lithium batteries is that they have an expiration date, independent of the use made of them.
A wise and correct use, limiting extreme stress situations, can undoubtedly benefit your performance, but it certainly does not "extend its life" beyond the natural deadline. Their duration today is decidedly lower than the classic NI-Mh or lead-acid batteries, more long-lived but with the problem of the memory above effect and the lower constancy of their efficiency.
Does Lithium-Ion Battery Have Side Effects?
The explosion of smartphone and tablet batteries can cause the emission of more than one hundred toxic gases, even more, dangerous if the accident occurs in a small and closed place such as the passenger compartment of a car.
In recent weeks there have been numerous cases of explosions on the media all over the world, which have also brought a giant like Samsung to withdraw one of its latest products from the market. There has been the talk of explosions and fires, but little has been said and understood about the gas emissions that these accidents can cause.
It has thus been discovered that the explosion causes the emission of dozens of highly toxic gases, potentially even fatal, which can cause severe irritation to the skin, eyes, and upper respiratory tract. The type of gases and their concentration depend on many factors, for example on the exact chemical composition of the battery, on the level of charge, on the size and level of aeration of the environment in which the explosion occurs.
Is It Safe To Use A Lithium-Ion Battery Than Any Other Battery?
Lithium is a chemical element often indicated with the symbol Li and with atomic number 3. It is part of the group of alkaline metals and in its pure form is a silver-colored metal. In addition to consumer devices, lithium-ion batteries are playing an increasingly important role in the Data Center.
The fundamental reason is that the advent of the Internet of Things (IoT) means that a myriad of processing and network devices are now installed in areas outside the traditional perimeter of the data center: branches and home offices, sales outlets, industrial sites, even outdoor areas such as wind and solar plants.
The multiplication and distribution of IT, paradoxically, increases the risks of disruptions, if a member of the chain should experience problems, in particular concerning the fundamental - and sometimes forgotten - a source of information technology functioning: the current electricity. To take shelter, organizations must equip themselves with special uninterruptible power supplies (UPS) capable of powering the devices in the event such problems arise.
