The heat caused by mixing and phase is usually ignored. The first item in the right is electric power; the second term is the reversible heat; and is open circuit voltage. The heat generation of lithium-ion battery caused by side reactions under high temperature and voltage should not be ignored, which is defined as here.
As rechargeable batteries, lithium-ion batteries serve as power sources in various application systems. Temperature, as a critical factor, significantly impacts on the performance of lithium-ion batteries and also limits the application of lithium-ion batteries. Moreover, different temperature conditions result in different adverse effects.
The self-production of heat during operation can elevate the temperature of LIBs from inside. The transfer of heat from interior to exterior of batteries is difficult due to the multilayered structures and low coefficients of thermal conductivity of battery components , , .
For example, an appropriate temperature rise of LIBs due to self-heating improves the battery performance at low temperatures , , , , , , , while the overheating of LIBs hurts the life of the battery and can trigger thermal runaway in extreme cases , , , .
Their results indicated that high charging/discharging rate increased heat generation of lithium-ion battery and made it easier to thermal runaway. The inconsistency of lithium-ion batteries, inappropriate balancing control and malfunction of charge control may cause slight overcharging of battery [ ].
Battery heat builds up quickly, dissipates slowly, and rises swiftly in the early stages of discharge, when the temperature is close to that of the surrounding air. Once the battery has been depleted for some time, the heat generation and dissipation capabilities are about equal, and the battery’s temperature rise becomes gradual.

One of the most catastrophic failures of a lithium-ion battery system is a cascading thermal runaway event where multiple cells in a battery fail due to a failure starting at one individual cell. Thermal runaway can occur
It can be seen from Table 3 that the ohmic heat of 18650-type lithium-ion battery plays the key role in heat generation during charging/discharging. Besides, the sum of reversible heat during charging and discharging is zero. So, the Ohmic heat is the main reason of battery temperature increase during cycling.
As the energy density and charge rate increases, the optimal battery temperature can shift to be higher than room temperature. In the first part of the review various sources of heat generation inside LIBs and various approaches to minimizing battery heat generation are summarized.

This is not a new phenomenon, and fortunately it is also a rare one. In 2006 millions of lithium-ion battery packs made by Sony were replaced after several hundred overheated and a few caught fire.
Lithium-ion batteries (LIBs) have already been used successfully in some areas such as everyday electronics and electric vehicles [1].However, fire and explosion accidents caused by thermal runaway (TR) of LIBs are frequently reported [2].There are three modes to trigger the TR of batteries, including electrical abuse, thermal abuse and mechanical abuse [3].
For safety reasons, lithium-ion batteries include a separator. This prevents the electrodes of the battery''s cells from touching each other. But if this separator gets ripped or damaged, the electrodes can touch. This can …
