While the mechanism by which an upper cut-off voltage affects the performances of lithium-ion batteries has been extensively studied, the effect of a lower cut-off voltage (LCV) on the cycle life and safety of lithium-ion batteries, especially nickel-rich layered oxide/graphite–SiO x batteries, is poorly understood.
Thin-film lithium-ion batteries offer improved performance by having a higher average output voltage, lighter weights thus higher energy density (3x), and longer cycling life (1200 cycles without degradation) and can work in a wider range of temperatures (between -20 and 60 °C)than typical rechargeable lithium-ion batteries.
The thin-film batteries were characterized by cyclic voltammetry (CV) and constant current (CC) charge-discharge measurements. A thin-film battery was placed in a vacuum-tight vessel with electrical feedthrough. The sample was kept under vacuum during the measurement by evacuating with a rotary pump.
The concept of thin-film lithium-ion batteries was increasingly motivated by manufacturing advantages presented by the polymer technology for their use as electrolytes. LiPON, lithium phosphorus oxynitride, is an amorphous glassy material used as an electrolyte material in thin film flexible batteries.
Thin-film lithium-ion batteries have the ability to meet these requirements. The advancement from a liquid to a solid electrolyte has allowed these batteries to take almost any shape without the worry of leaking, and it has been shown that certain types of thin film rechargeable lithium batteries can last for around 50,000 cycles.

Thin films of LiCoO 2 have been synthesized in which the strongest X-ray reflection is either weak or missing, indicating a high degree of preferred orientation. Thin film solid state batteries with these textured cathode films can deliver practical capacities at high current densities.
