The battery capacity of metallic lithium decreases as the charge and discharge cycles are repeated, and lithium precipitates in needle-like and dendritic crystals (lithium dendrites) when charged more rapidly [40]. Lithium dendrites have a large specific surface area, accelerate the decrease in current efficiency due to side reactions, and they may break

The viscosity of certain non-aqueous electrolytes comprising a first lithium salt which can gel on the addition of P2O5 can be reduced substantially by incorpor-ating therein a small amount of a suitable viscosity reducing salt. In particular, the viscosity of a LiPF6 salt based electrolyte can be reduced by orders of magnitude by incorporating a small amount of LiBF4 therein.

In half-cell testing, the use of 1.0 mass% LiBOB additive distinctly improved the battery’s efficiency. Further investigations in full-cell systems revealed that at 30 °C, the capacity retention with a 1.0 mass% additive concentration was slightly higher than that with 3.0 mass%.
These solvents are combined with lithium salts, such as LiPF 6 or LiBF 4, and the mixture also includes various additives. This combination is essential for the functioning of LIBs, providing the necessary components for energy storage and release during the LIBs’ operation .
The use of additives stabilizes the properties of SEI during formation. With a stable SEI, ion conductivity, thermal stability, and cycle life are all improved while also addressing the problem of initial capacity loss. Developing non-flammable electrolytes remains a key aspect in enhancing battery safety.
Various parameters, such as ion conductivity, viscosity, dielectric constant, and ion transfer number, are desirable regardless of the battery type. The ionic conductivity of the electrolyte should be above 10 −3 S cm −1. Organic solvents combined with lithium salts form pathways for Li-ions transport during battery charging and discharging.
Organic additives like quercetin serve as antioxidants and are employed as additives in LIBs. The presence of quercetin enhances the electrochemical performance of lithium batteries, with a capacity retention of 92% at a voltage range of 2.8–4.3 V after 350 cycles at a 1 C rate.
The Li/LiMn 2 O 4 battery with the additive of tris (pentafluorophenyl)borane (BCF) demonstrates excellent capacity retention and cycling efficiency at 55.0 °C . Because of separation, the enrichment of Li + PF 6− ions enables the additive to form a protective layer on the electrode surface, thereby extending the cycle life .
