The problem of lithium-ion battery safety has been recognized even before these batteries were first commercially released in 1991. The two main reasons for lithium-ion battery fires and explosions are related to processes on the negative electrode (cathode). During a normal battery charge lithium ions intercalate into graphite. However, if the charge is forced to go too fast (or at. It’s usually around 3.6V to 3.7V for a fully charged cell. Working Voltage: This is the actual voltage when the battery is in use. It’s generally lower than the open circuit voltage due to internal resistance. Cut-off Voltage: This is the minimum voltage allowed during discharge, usually around 2.5V to 3.0V per cell. [pdf]

A technology capable of harvesting lightning energy would need to be able to rapidly capture the high power involved in a lightning bolt. Several schemes have been proposed, but the ever-changing energy involved in each lightning bolt renders lightning power harvesting from ground-based rods impractical: too high and it will damage the storage; too low and it may not work. Additionally, lightning is sporadic, and therefore energy would have to be collected and stored; i. [pdf]
Lightning is not distributed evenly around . On Earth, the lightning frequency is approximately 44 (± 5) times per second, or nearly 1.4 flashes per year and the median duration is 0.52 seconds made up from a number of much shorter flashes (strokes) of around 60 to 70 . Many factors affect the frequency, distribution, strength and physical propertie. The Earth can store a significant amount of lightning energy. Every day, there are approximately 8.6 million lightning strikes, each discharging up to one billion Joules of electrostatically stored energy1. A single bolt of lightning carries about 7 gigajoules of energy, equivalent to the energy stored in 38 Imperial gallons or 172 liters of gasoline2. [pdf]
