Advanced Materials for Lithium Ion Batteries – Phase IV

NCMS Project #: 142041

Problem: Energy storage is a critical need in modern society, from applications as diverse as grid energy storage to vehicle powertrains to personal electronic devices.  Batteries using currently available active materials for energy storage are unlikely to meet future demands for energy density.  Ongoing research is producing higher energy density active materials; however, these new materials pose additional problems in stability and performance.

Benefit: More efficient batteries with higher energy reduce overall vehicle weight, reduce hazards associated with vehicle damage, and lower vehicle maintenance and sustainment requirements.  Novel materials that enable more tailored battery performance can expand the utility of the batteries, improving consumer confidence and enabling greater global competitiveness for manufacturers.

Solution/Approach: Leveraging previous successes in Phases I and II, and the ongoing work in Phase III, this phase will study new advanced materials and thermal management systems for leveraging coating technologies that may further increase battery energy density and life as well as focusing on the safety of high-energy battery.  The goal is an optimum operational temperature in cold climate operations and protection against the temperature extremes that can lead to catastrophic battery failure.
