It may be due to the deposited lithium on the anode surface of the batteries would react exothermically with the electrolyte at a lower temperature (Wang et al., 2020). For the onset time of TR, it also reduced from 441 s at 25 °C/0.5 C to 162 s at − 10 °C/1 C, which indicates that lower operating temperatures and larger cycle

Overcharge is one of the most severe safety problems for the large-scale application of lithium-ion batteries, and in-depth understanding of battery overcharge failure
Corrosion is one of the most frequent problems that affect lead-acid batteries, particularly around the terminals and connections. Left untreated, corrosion can lead to poor conductivity, increased resistance, and ultimately, battery failure.
In an acid stratified battery, shedding, corrosion, and sulphation happen much faster at the bottom of the plate, leading to earlier battery failure. Moreover, modern vehicle batteries that operate in a Partial State of Charge (PSOC) seldom receive a full charge and/or are constantly deeply cycled or micro-cycled combined with acid
In lithium-ion batteries, battery degradation due to SOC is the result of keeping the battery at a certain charge level for lengthy periods of time, either high or low. This causes the general health of battery to gradually deteriorate. Long-term full-charge times (high SOC) can lead to the production of unwanted byproducts such the solid

With each cycle, various physical and chemical processes contribute to the gradual degradation of the battery components . Mechanical stress resulting from the expansion and contraction of electrode materials, particularly in the anode, can lead to structural damage and decreased capacity .
The result is grid wires become exposed to accelerated corrosive activity during charge. And over time, these conditions cause the battery to fail. In an acid stratified battery, shedding, corrosion, and sulphation happen much faster at the bottom of the plate, leading to earlier battery failure.
State of Charge In lithium-ion batteries, battery degradation due to SOC is the result of keeping the battery at a certain charge level for lengthy periods of time, either high or low. This causes the general health of battery to gradually deteriorate.
In more severe cases, excessive heat can cause the dissolution of the battery's structural components and the decomposition of the electrolyte. These thermal and chemical breakdowns can trigger a series of adverse side reactions within the battery, ultimately leading to BTR [112, 113].
Several factors contribute to battery degradation. One primary cause is cycling, where the repeated charging and discharging of a battery causes chemical and physical changes within the battery cells. This leads to the gradual breakdown of electrode materials, diminishing the ability of the battery to hold a charge.
In a corroded battery, much of the current gets lost to resistance (in the form of heat) as the grid wires become exposed and/or disconnected from the active materials.
