Never charge a primary (disposable lithium or alkaline) battery; store one-time use batteries separately. Charge or discharge the battery to approximately 50% of capacity before long-term storage. Use chargers or charging methods designed to charge in a safe manner cells or battery packs at the specified parameters.
Moreover, a lithium-ion battery pack must not be overcharged, therefore requires monitoring during charging and necessitates a controller to perform efficient charging protocols [13, 23, 32, 143 - 147].
In this paper, we investigate a novel thermal barrier placed between the individual cells to prevent thermal propagation (TP) in lithium-ion battery packs. A single cell failure may cause different exothermic reactions leading to an uncontrolled release of heat that can trigger subsequent reactions causing a thermal runaway (TR).
However, a battery pack with such a design typically encounter charge imbalance among its cells, which restricts the charging and discharging process . Positively, a lithium-ion pack can be outfitted with a battery management system (BMS) that supervises the batteries' smooth work and optimizes their operation .
A battery usually consists of a pack of cells connected in series. Manufacturing processes lead to imperfections in cells, as a result of which, all the cells in a pack are not identical. Electrical imbalances occur during charging and discharging of battery packs. Some cells in a battery will have different voltage levels for the same charging.
Battery charging control is another crucial and challenging part of the BMS since it can control the overcharging, overvoltage, charging rate, and charging pattern. These functions lead to a better battery performance with improved lifetime and reduced safety hazard and capacity fade risks .
