An energy transformation is underway, moving toward an "electron" rather than fossil fuel energy economy. The constant delivery of clean electrical energy presents a global challenge - once electrical energy is generated, it must be used, or it is wasted. To overcome this challenge, energy storage has a strategic importance to bridge the gap between energy generation and demand, support a transportation revolution toward electrified vehicles, and ensure that the energy transition uplifts all individuals and communities regardless of socioeconomic status. At IESE, researchers are building the scientific foundation for advanced energy storage systems that meet current and future energy needs.
Research Area 1 - Scalable Energy Storage
IESE researchers are investigating scalable, cost-effective, and environmentally safe energy storage materials and systems to support full integration of renewable forms of energy such as wind and solar into a modernized electric grid. Grid-scale batteries using water as the electrolyte rather than the flammable solvents traditionally used for lithium-ion batteries are under study.

IESE researchers report a zinc chloride water-in-salt electrolyte that increases stability
of an aqueous zinc/molybdenum oxide battery by protecting the zinc anode surface from
dissolved molybdenum species and minimizing hydrogen gas evolution.

IESE results demonstrated that variation of heat treatment of sodium vanadium oxide
materials lead to differences in material properties that affect the aqueous zinc
electrochemistry. The samples had distinct cyrstallite, particle size, interlayer
water, and surface area and impacted the delivered capacity, rate capability, and
capacity retention of zinc-ion aqueous cells. The electrochemical electron transfer
was noted to be linked to change in vanadium oxidation state through the use of operando
X-ray absorption spectroscopy

Research Area 2 - Transportation-Relevant Energy Storage
IESE researchers are studying reaction mechanisms and improving design of high-energy,
high-power electrode materials and systems to accelerate adoption of electric vehicles.
IESE researchers demonstrate interfacial modification of graphite electrodes via direct
current (DC) magnetron sputtering of nanoscale layers of Cu and Ni as a means to increase
the overpotential for Li deposition and suppress Li plating under high rate charge
condition. This research may help pave the way toward faster charging cars.

The degradation mechanisms of lithium nickel manganse cobalt oxide, a cathode system
often used for electric vehicles, at high and low voltage are revealed through X-ray
absorption spectroscopy, X-ray fluorescence mapping, diffraction, microscropy, and
electrochemical testing. The results are important toward understanding the trade-offs
of battery use conditions versus their life time.

A goal for vehicle batteries is increasing their energy content. One approach is to
use high-capacity silicon as a negative electrode material as that would provide about
10x the capacity of a graphite electrode. The challenge for silicon is the stability
and cycle life of the negative electrodes. IESE probes parasitic reactions during
the lithiation of a silicon electrode using operando isothermal microcalorimetry yielding insight into surface-electrolyte interactions
and demonstrating that an approach can be broadly applied to quantify parasitic reactions
in other complex systems.

Research Area 3 - Research in Service of Human Health
IESE researchers are committed to advancing small, adaptable, and reliable energy
storage systems and characterization approaches that aid the treatment and diagnosis
of human health.
IESE Director Prof. Esther Takeuchi is well-known for inventing and refining the lifesaving

IESE scientists are developing a self-forming, self-healing solid-state rechargeable
battery based on the Li/I2 coupling using LiI-rich lithium iodide-(3-hydroxyproprionitrile)2
electrolyte. This battery design builds on the primary Li/I2 batteries, which have
been successfully deployed commercially for implantable pacemakers with an exceptional
record of reliablility. The research demonstrated a self-healing solid-state battery
with high coulombic efficiency.

Recently, IESE used synthesis and characterization science developed for energy storage
to understand virus dispersion. Functionalized nanoparticles were synthesized, suspended
in artificial saliva, and dispersed by aerosol onto N95 face masks to mimic coronavirus
transmission. Synchrotron-based X-ray fluorescence mapping effectively visualized
the dispersion of the virus mimic on the masks. This research probed the concept of
adsorption as an important mechanism for effective mask function.
