However, on an extremely light load over a long discharge period, the battery''s capacity may be reduced due to self-discharge. The relationship between load and battery performance is that a battery typically delivers more capacity when discharging at a light load compared to a heavy load.
In general, the heat generation within the LIBs at normal temperature is associated with charge transfer and chemical reactions during charging and discharging [84], [85].The heat is generated either in the reversible process or the irreversible process in LIBs [84], [86], [87], [88]. Fig. 3 shows the possible heat generation within LIBs. The heat …
