“…Rajaganapathy et al analysed the friction and wear results by adding CuO and TiO 2 at 0.1 and 0.5 wt% to palm and brassica oil using a pin-on-disk tribometer. 53 The palm oil sample with 0.5 wt% CuO exhibited superior reduction in COF and wear. Additionally, the viscosity and thermal conductivity of the evaluated fluids increased because of the increasing nano-particle concentrations.…”

According to the Environmental Protection Agency, transportation is the largest contributor of greenhouse gas emissions (28% of total emissions). Electric vehicles have remarkably grown in popularity and represent a greener future for the automotive industry. This growth has prompted lubricant and grease technology to adapt to an entirely new environment, which is exposed to new factors including external electric currents/fields and extreme temperatures and pressures originating from electric motors and power electronics. Consequently, novel lubricants and greases need to be developed and explored to ultimately improve fuel efficiency and performance. Nano-additives have offered exceptional opportunities to enhance electrical, thermal and tribological properties of the lubricants and greases used. It is thus vital to fully explore and understand the effects of nanoparticles' addition to lubricants and greases, as well as the mechanisms by which improvements are obtained. This perspective summarises the recent trends of developing lubricants and greases for electric vehicles.

“…46 More recent fluid engineering efforts employ the utilization of nano-materials, including TiO 2 and CuO, 47 which withhold promising advantages toward manipulating the characteristics of standard base oils. According to Rajaganapathy et al, 16 the coefficient of friction (COF) was greatly reduced by the addition of 0.5 wt.% CuO to palm oil. Ali et al 48 analyzed the frictional performance of copper/graphene additives in automobile engines.…”

“…15 Lubricants applicable to traditional ICE vehicles can be translated to EVs, however, attention must be paid on the lubricant's electrochemical properties, corrosion resistance from copper, and interaction with elastomers/polymers found in EVs. Nano-additives, such as TiO 2 and CuO, 16 offer an interesting approach to alter the oil properties thus becoming more applicable in EVs.…”

Future progress in hybrid and battery vehicles heavily relies on the optimization of involved battery components and lubricants. Attention must specifically be given to the material composition and surface coatings of the electrodes as well as the electrolyte used to maximize energy output, while also ensuring safety. Additionally, prioritizing the effective utilization of specific lubricants for electric motors and various tribological contacts, such as wheel bearings and the steering system, is the prospective goal of lubrication research. The energy output of the most promising battery, the Li-ion battery (LIB), must result in driving ranges, which can compete with the 600 km driving range of combustion engine (ICE) vehicles. Consequently, ongoing research activities in cell chemistry, electrode surface engineering, electrolyte engineering, and engine lubrication offer the greatest opportunity in achieving these goals.

“…Friction reduction additives are used to ensure the lubricating properties in the friction boundary regime [1][2][3][4][5]. Other additives act on the oiliness of the lubricant [6][7][8][9]. Natural oils developed with vegetal or animal biomass, and fats present better friction and wear performances than mineral oils.…”

Many researches are focused on the tribological performances of pure vegetable oil in order to replace the conventional mineral engine oils. This work investigates the influence of local moringa oil (noted VO) on the performances of lubricants formed from a blend of dodecane and graphite particles at ambient temperature. In a first part, a reduction of about 50% of friction properties of dodecane is observed when adding small amounts of moringa oil (VO), which is intended to be used as a bio-base performance additive in lubricant formulations. The friction properties of their blends with graphite, generally employed as solid lubricant additive, showed an adsorption effect of fatty acid molecules. The more promising results were obtained for the blend containing 2 w% of VO. Physicochemical characterizations of the tribofilms evidence the good antiwear properties of the lubricant.
