Abstract High refractive index and transparent materials are useful in various technical domains, ranging from energy sector to microelectronics. This work deals with polymer composites prepared by embedding small amounts of barium titanate in hydroxypropyl cellulose matrix. Optical transparency of the composite films varies in agreement with polymer doping level. Light dispersion in the prepared composites allowed evaluation of specific parameters, which are related to the sample structural order and possible optical transitions. Conductivity of the composites is increased due to ceramic particle addition in the polymer. Dielectric studies reveal that the prepared materials are suitable for electric energy storage applications.

Battery Module

Modelling, simulation, and validation of the 12-volt battery pack using a 20 Ah lithium–nickel–manganese–cobalt–oxide cell is presented in this paper. The cell characteristics influenced by thermal effects are also considered in the modelling. The parameters normalized directly from a single cell experiment are foundations of the model. This approach provides a systematic integration of actual cell monitoring with a module model that contains four cells connected in series. The validated battery module model then is utilized to form a high fidelity 80 Ah 12-volt battery pack with 14.4 V nominal voltage. The battery cell thermal effectiveness and battery module management system functions are constructed in the MATLAB/Simulink platform. The experimental tests are carried out in an industry-scale setup with cycler unit, temperature control chamber, and computer-controlled software for battery testing. As the 12-volt lithium-ion battery packs might be ready for mainstream adoption in automotive starting–lighting–ignition (SLI), stop–start engine idling elimination, and stationary energy storage applications, this paper investigates the influence of ambient temperature and charging/discharging currents on the battery performance in terms of discharging voltage and usable capacity. The proposed simulation model provides design guidelines for lithium-ion polymer batteries in electrified vehicles and stationary electric energy storage applications.
