The storage of global energy system can install all over the world, which is for good reason. For this system we got a lots of benefit but along with benefits, lots of disadvantage of this system. In this article discuss the failure of this energy storage system and it’s hazards.
While there are different types of energy storage system. For energy storage system required high safety and longer life cycle while large scale application.
Now, we discuss to explore both the operating and failure mechanism of energy storage system. In this topic focus on lithium ion battery energy storage system. The size of this battery is higher but the hazards and failure seen for all types of battery.
Firstly discuss on hazards of the system.
According to the research most of the electric equipment has common hazards that needs the maintenance such as electrical shock and arc flash. Also the main focus on how to work with electric equipment safely. Thermal runaway which is uncontrollable self heating of battery cell. Inside the battery when generate the excess amount of heat which can dissipated the surroundings. From initial overheated cell can be produce flammable and toxic gases. Gases which released from battery storage energy system can be highly flammable and toxic. According to battery chemical reaction dependent the type of gases will released such as carbon monoxide, carbon dioxide, hydrogen, methane, ethane and another hydrocarbons. It’s dangerous that when gases will able to reach low explosive limit before finding ignition it might be get explosive. Main important that is standard energy, this terms used for when battery has no safe way to discharged it’s storaged energy. This standard energy has leads to reignition of fire within a minute, or a hour.
Let’s discuss on the failure of the system; it have several way when battery get defected resulting it’s fires, explosion and also released toxic gases. Energy storage system have fixed range of temperature according to designs, according to the uses. When it operated at the acceptable temperature range, and the energy’s storage system may not work at this position may cause premature aging of battery or it even get completely damage that can lead to fire and explosion. These thermal abuse can be cause by external source. This about the thermal abuse now see the electrical abuses, it can be happened when battery get overcharged, charged rapidly or any external short circuit. It can also happened when battery get over discharged or rapidly discharged. When battery get overheated it might get explosion.
Now come to the mechanical abuse, when it get physically compromise like battery is crushed, dropped and destroyed by mechanical force. It can also failed energy storage system when it get internal fault due to inadequate design. Due to uses of low quality materials or default in manufacturing. Environmental impact also make the battery failure like dust , due to flood, ingress of debris or corrosive mists like dust, salt fog or rodent damage in wiring. Due some areas where temperature get fluctuating like mountain due to dewing it might be damage the energy storage system.
Now important to explore the importance of operating and failure mechanisms of energy storage devices. The previous device such as X-ray diffraction, transmission electron microscopy, topography, nuclear magnetic resonance all these are based on Electrodes. The research can evaluate the atmospheric dependent relaxation and failure process of energy storage devices by situ Raman. They found that the aluminum ion battery, and the effect of graphite electrodes in anhydrous atmosphere where it in stage of structure are recoverable and electronic relaxation. These mechanism has describe as the redistribution of anion and cation in a graphite electrodes.
