Since lithium-ion batteries can be expensive, here are some tips to extend their lifespan:
Avoid fully discharging the battery as the lithium-ion chemistry promotes partial discharge rather than deep discharge. Since there is no “memory” in lithium-ion chemistry, even repeated partial discharges do not affect the battery pack. A LiFePO4 cell is damaged or destroyed if its voltage falls below a certain threshold.
Over time, a LiFePo4 battery loses its capacity. Their service life is limited to two to three years, regardless of how often they are used or stored. You shouldn’t “avoid using” a battery if you’re assuming a battery life of five years. In addition, you must make sure that the battery you are buying is new. Things that have lain on a store shelf for a year have a much shorter shelf life. Manufacturing dates are critical, remember heat is bad for batteries and should be avoided.
Batteries for Explosion-Processing:
- Now that we know how to extend the lifespan of lithium-ion batteries, let’s look at why they periodically burst.
- If the temperature of the battery rises to the flammable level of the electrolyte, a fire will break out. Videos and photos that have been released show the extent of the damage caused by the flames. The CBC article “Summer of the Exploding Laptop” has several such cases.
- Internal battery short circuits are the most common source of this type of fire. Remember how the sheet works as a separator to separate the positive and negative electrodes in the lithium-ion batteries from the previous thread? Each time the electrodes come close due to a rupture or damage to this sheet, the battery begins to heat up. If you’ve ever had a 9-volt battery in your pocket, you’ve probably felt the heat it gives off. The battery will overheat if a short circuit occurs between the two terminals, which may be caused by a coin being dropped.
- When a LiFePo4 battery separator breaks, the same short circuit occurs. Lithium-ion batteries generate a significant amount of heat due to their high energy consumption. Battery electrolyte is vaporized by heat and can be started either by heat or by a nearby spark. As soon as a fire breaks out in one of the cells, it quickly spreads to the rest of the pack, engulfing everything in flames.
It is important to remember that fires are not everyday occurrences. Regardless, it takes a few fires and little media attention to trigger a product recall.
