INCREASING ENERGY DENSITY: CATHODES
Mary Ann Brown, Executive Director, Conferences, Cambridge EnerTech
Advanced High-Energy Lithium-ion and Beyond
To achieve high electric drive range, a new battery system with advanced high-capacity cathode and stabilized high-capacity anode is needed. In this talk, we will disclose several strategies to increase the energy density of battery through the development of continuous gradient cathode material coupled with high voltage electrolyte. We also disclose a new conformal coating strategy that eliminates spinel structural transition of NMC at high voltage.
Fast-Charging Zero-Cobalt Zero-Strain Stoichiometric Layered Cathodes
In this talk, I will talk about a universal strategy to entirely eliminate cobalt and reduce Ni content in traditional stoichiometric layered cathodes (e.g. NMC, NCA, etc.) while preserving the high specific energy (>800 wh/kg), high charge rate (>180 mAh/g at 3C), moderate upper cutoff voltage (4.3 V vs. Li).
Potassium-ion Batteries for Low-Cost Energy Storage
This presentation will introduce an emerging low-cost alternative battery system (K-ion batteries) and discuss key structural factors determining K intercalation properties and performance. Then, the discussion will be expanded to understand how the synthesis process dictates material's structure and their K storage properties.

Next-Generation Cathodes Free of Ni and Co
Many lithium-ion batteries use nickel and cobalt as redox-active elements. Reducing or eliminating the use of nickel and cobalt represents a grand challenge in developing low-cost and sustainable batteries. In this presentation, we will first discuss our recent progress in eliminating the use of cobalt in lithium-ion batteries. We investigate the electrochemical properties of cobalt-free layered cathodes in various platforms, from conventional polycrystalline materials to size-tailored single crystals. Then, we will highlight a new class of nickel- and cobalt-free cathode materials with dual transition metal redox. We will demonstrate how our battery research has been accelerated by synchrotron techniques.
High-Energy-Density Cathode Material CFx: Discharge Mechanism and Beyond
Lithium/fluorinated graphite (Li/CFx) primary batteries show great promise for applications in a wide range of energy storage systems due to their high-energy density and low self-discharge rate. Multiscale investigations are performed on the precisely controlled CFx cathode to understand the discharge mechanism. The unveiled insights in turn guide the systematic design of this battery chemistry with superior electrochemical performances and beyond.
Can Oxides be Functional Cathodes in Mg Batteries?
To transcend Li-ion batteries, interest exists in devices coupling an Mg metal anode and an oxide cathode. In this talk, I will discuss the most up-to-date insight into the ability of oxides to act as functional Mg cathodes in non-aqueous electrolytes, to enable the use of Mg metal anodes. The discussion will naturally lead us to reveal foundational bottlenecks and immediate questions that must be addressed to ever make Mg batteries a viable technology concept.

INCREASING ENERGY DENSITY: ELECTROLYTES
Cation Solvation in Battery Electrolytes
Multivalent metal anodes contain sufficient gravimetric and volumetric capacity to replace lithium-ion battery materials, but issues associated with anode utilization and reversibility persist. This talk will summarize a diversity of studies led by the Army Research Laboratory and linked by electrolyte engineering of cation solvation, with a primary goal of realizing energy-dense multivalent batteries.
Genomic-Level Electrolyte Property Predictions for Rapid Screening and Optimization, with Emphasis on Highly-Concentrated Electrolytes
The INL Advanced Electrolyte Model (AEM) has a molecular-scale chemical physics foundation that generates predictions spanning more than 100 property metrics per simulation. As such, AEM gives genomic-level information that supports fast holistic screening of electrolytes. Examples include transport terms (viscosity, diffusivity, conductivity, etc.), cation desolvation energy and kinetics (ligand-wise and net), thermodynamic equilibrium terms, surface tension, thermophysical properties (relative molal enthalpy, excess heat capacity, thermal conductivity), solution permittivity, and others. AEM covers broad ranges of salt concentration and temperature, enabling investigation of highly-concentrated electrolytes (HCEs) and localized HCEs (LHCEs). Case studies will show HCE candidates for fast-charge Li-ion batteries.
Vapor Phase Modification of Battery Materials: Li-metal, Cathodes and Solid Electrolytes
Complete solid-state lithium-ion batteries has attracted great attention due to their safety, high energy density and higher operating voltages. The interface of the between Li-metal to solid electrolyte and solid electrolyte to active cathode material is very important factor in getting desired performance. We are working on surface interface engineering and stabilizing battery materials such as Li-metal, solid electrolytes, and high voltage cathode materials via cost effective and salable precursor vapor phase processing method. Here will present latest encouraging results and learning that will be helpful for both battery research community as well as battery manufacturers.

INCREASING ENERGY DENSITY: ANODES
Lithium Metal Anode Stabilization with Advanced Electrolytes
The drive to increase the energy density of batteries has drawn much-revived interest to employ lithium metal as an anode with both oxide and sulfur cathodes, but its practical implementation is met with challenges. This presentation will focus on achieving efficient lithium plating and stripping with high coulombic efficiency by designing advanced electrolytes. A fundamental understanding of the factors involved in improving the efficiency will be discussed.
Alloying Strategy to Stabilize Metal Anode for Researchable Batteries
Safety and durability concerns caused by surface and interface instabilities of high-surface-activity energy materials are challenging modern electrochemical energy storage systems. In order to stabilize the surface and interface of energy materials, some surface and interface (strain, gradient, defect, confinement, etc.) engineerings are under consideration. In this presentation, I will introduce a new strategy to resolve the interfacial instability issues of battery materials using alloying strategy. Comprehensive studies based on experimental, theoretical, spectroscopic, and microscopic approaches prove that high reversibility can be achieved by using the proposed alloyed anodes because of the significantly improved diffusion and suppressed dendrite growth.

If a Lithium-ion Cell Can Operate for More Than 6 Months at 85°C How Long Can It Last at Ambient Temperature?
In a few of our recent papers, we have presented Li-ion cell designs with liquid electrolytes that give astounding lifetime at temperatures as high as 85°C. In fact, we have been testing these cells now at 100°C and they are operating well for more than one month so far. I will discuss what is required to make such awesome cells and then consider what their lifetime at ambient temperature might be. I will show that the energy density of these cells is very reasonable and that Co-free moderate-nickel designs also work equally well.
