Studies have shown that lithium-ion batteries suffer from electrical, thermal and mechanical abuse , resulting in a gradual increase in internal temperature.When the temperature rises to 60 °C, the battery capacity begins to decay; at 80 °C, the solid electrolyte interphase (SEI) film on the electrode surface begins to decompose; and the peak is reached
In the paper , for the lithium-ion batteries, it was shown that with an increase in the number of the charge/discharge cycles, an observation shows a significant decrease in the temperature, at which the exothermic thermal runaway reactions starts – from 95 °C to 32 °C.This is due to the fact that when the lithium-ion batteries are cycled, the electrolyte decomposes

Fundamentally, the challenge of ensuring battery quality is driven by the complexity of battery performance. An especially important, sensitive, and complex pillar of battery performance is battery lifetime and failure.
All batteries experience performance degradation to some degree, and minimizing its extent is critical to improve battery sustainability and to bring next-generation battery chemistries to market 45. Furthermore, the long duration of electrochemical lifetime testing is a major bottleneck to innovation in battery technology 46, 47.
In other words, even when the linked program is not consuming any energy, the battery, nevertheless, loses energy. The outside temperature, the battery's level of charge, the battery's design, the charging current, as well as other variables, can all affect how quickly a battery discharges itself [231, 232].
Improving the safety of batteries is a systematic project, and at a time when there has been no breakthrough in the chemical system, improvements, such as build a practical graded warning system, are needed in all aspects of design, production, use and disposal to improve battery safety and minimize the risk of failure. 1.
