Because lithium-ion battery packs can be pricey, here are some suggestions for extending their lifespan:
Avoid completely depleting the battery because lithium-ion chemistry favors partial discharge over deep discharge. Because the lithium-ion chemistry lacks “memory,” even repeated partial discharges do not affect the battery pack. A lithium-ion battery’s cell is damaged or destroyed if its voltage falls below a certain threshold.
Over time, a LiFePo4 Battery loses its capacity. Their lifespan is limited to two to three years, regardless of how frequently they are used or stored. You should not “avoid using” the battery if you assume that the battery pack has a five-year lifespan. No, there isn’t. Additionally, you should ensure that the battery pack you purchase is new. Things that have been on a store shelf for a year have a significantly reduced shelf life. The dates on which manufactured things are critical, remember that heat is bad for batteries and should be avoided.
Explosion-Processing Batteries
- Now that we know how to lengthen the lifespan of lithium-ion batteries let’s look at why they occasionally burst.
- If the battery’s temperature rises to the level the electrolyte ignites, a fire will break out. The video and still images that have been made public show the extent of the damage caused by these flames. The CBC’s “summer of the Exploding Laptop” piece includes several of these occurrences.
- Internal shorts in the battery are the most prevalent source of this type of fire. Remember how a sheet functions as a separator to separate the positive and negative electrodes in lithium-ion batteries from the previous topic? Any time the electrodes come into proximity due to tearing or damage to that sheet, the battery begins to heat up. If you’ve ever had a 9-volt battery in your pocket, you’ve likely felt the heat it generates. The battery will overheat if there is a short between the two terminals, which a coin might cause.
- When a LiFePo4 Battery separator breaks, the same short circuit occurs. Lithium-ion batteries generate a significant amount of heat as a result of their high rate of energy consumption. Battery electrolyte is evaporated by heat, and either the heat or an adjacent spark is capable of starting it. As soon as a fire breaks out in one of the cells, it quickly travels to the rest of the pack, engulfing everything in flames.
Keeping in mind that fires aren’t everyday occurrences is essential. Despite this, a few fires and a little media attention are needed to induce a product recall.
