By 2040, the Department of Energy (DOE) projects 65 million new electric vehicle sales worldwide, creating a need for 309 million home and public charging stations. To meet this daunting demand, EV batteries will need to charge faster, last longer, have a smaller profile, and reduce dendrite formation that leads to battery fires.

To meet these challenges, batteries will need to see improved energy density, greater conductivity, and a decrease in resistance, which will place EV batteries on a trajectory to meet the forecasted demand.

EVŌQ Nano has engineered a unique nanomaterial called EVQGA, which enhances next-generation energy storage systems (e.g. Lithium-ion, Sodium-ion and Graphene) in two fundamental areas: first, the enhancement of electroactive species formations in battery electrolyte; and second, in improvements in conductivity and reduction in resistance with anode and energy transport materials.

EVQGA is engineered using a patented high-energy method that ensures specific chemical and physical characteristics. One result of EVQGA’s unique characteristics is that when EVQGA is applied in any solution, the particles are evenly distributed and never fall out of solution. This is critical to improving the energy density of rechargeable batteries. Additionally, the material is inherently stable because it is non-emissive. Emissive particles could cause unwanted chemical reactions as well as material degradation over time.

When applied to a rechargeable battery’s electrolyte, EVQGA is equally distributed throughout the battery’s cell. These individual particles behave as seeds in the battery electrolyte. As the battery goes through the standard charging process, electroactive species (crystals) begin to form and grow at the nanoparticle sites. This results in smaller, but more numerous formations that ultimately results in greater energy density. The energy required to form the crystals is reduced, which allows for faster charging times. Due to the increase in energy density within the battery cell, the battery’s charge lasts longer. Finally, the smaller, and uniformly dispersed crystal formations inhibit the formation of dendrites, which are responsible for battery shorting and catching fire.

The long-term impacts of increased energy density also include EV batteries that may be manufactured with a smaller footprint, that will meet the challenges forecasted by the DOE, and that will have a longer life which is critical to all renewable initiatives.

Improvements in conductivity along with reductions in resistance in energy transfer materials will have a significant impact in the EV battery industry. An increase in battery discharge power as measured in cold cranking amps will result in greater access to power while driving, and the enhanced torque expected in sports utility electric vehicles and electric pickup trucks. The ability to make these battery enhancements is a result of infusing EVQGA into the material (e.g. graphene) that is used to construct anodes and other energy transfer materials. Uniform distribution of EVQGA into these materials enhances the electron flow by decreasing the overall resistance of the energy transfer material, resulting in increased battery discharge power.
