3:35 High Capacity Cathodes Invoking Oxygen Redox

Peter Bruce, PhD, Faraday Challenge Institute

The search for Li-ion battery cathodes that exceed the limits of Ni rich NCM presents a significant challenge. One possible route is to store charge on the oxygen as well as the transition metal of lithium transition metal oxide cathodes. To harness the opportunities such material offer, it is necessary to understand the nature of O-redox processes and the factors that control them. O-redox in 3d transition metal oxides will be discussed, leading to a new high capacity manganese based cathode that utilizes the full capacity of the Mn as well as charge storage on oxygen.

3:55 Challenges and Opportunities for Implementing High-Nickel Cathode Materials in High-Performance Li-ion Cells

Suresh Sriramulu, PhD, CTO, CAMX Power

High-nickel cathode materials are increasingly being considered in Li-ion cells for automotive batteries. This presentation will review the challenges of implementing high-nickel cathode materials, especially in laminate pouch cells. We will discuss how lithium impurities (LiOH and Li2CO3), in conjunction with surface chemistry of high-nickel cathode materials, promote electrode slurry gelling and gas generation in the cell during elevated temperature storage and cycling. We will show why techniques typically used for measuring such impurities in low-nickel cathode materials are not suitable for high-nickel cathode materials and disclose methods for accurately characterizing such impurities.

4:15 Improvements to Disordered Rock-Salt Li-Excess Cathode Materials

Dee Strand, PhD, CSO, Chemistry, Wildcat Discovery Technologies

Cathode materials with higher energy density than layered oxide materials are required for future demands of vehicle electrification. Disordered rock-salt Li-excess structures, such as Li3NbO4, have been demonstrated to achieve capacities of greater than 300 mAh/g reversible capacities at elevated temperatures. The high capacity is believed to be due to reversible redox chemistry of the oxide anions. This new class of high energy cathode materials provides an opportunity for a step change increase in cell level energy density. However, improvements are still required in material conductivity and stability. In this presentation, we demonstrate material improvements which enable high specific capacity at room temperature and extended cycle life.

9:05 Non-carbonate Electrolytes for High Voltage/High Ni Chemistries

Kang Xu, PhD, Senior Research Chemist & Project Lead, US Army Research Lab

Dialkyl carbonate ester have been used as main electrolyte solvent since the dawn of Li-ion batteries and remains dominant in today’s LIB market. However, such solvents are intrinsically unstable with the next generation cathode materials of either high voltage (>4.5 V) or high Ni content. In this work we attempted to replace resolve these problems with a new class of non-flammable non-carbonate solvents that don’t generate gas at high V.

Li-ion technology has profoundly changed the battery landscape since its commercial introduction in 1991. However, it is now a mature technology, and incremental improvements to the energy density of Li-ion batteries are becoming increasingly difficult to achieve. The replacement of the carbon anode by lithium metal would allow for a substantial increase in energy density, but this is hardly a trivial task. In this presentation, we describe the use of glass protected Li-metal electrodes to eliminate the formation and propagation of Li dendrites, leading to high cycle life and high energy density batteries.

Novel and sustainable electroactive materials can help to decrease the ecological impact of novel battery concepts in the near future. While on the one hand high energy density is required, the aspects of safety, lifetime get more important and often mean a challenge. All these requirements are met by very different approaches with different characteristics: all solid-state cells, high-energy materials, lithium-sulfur and even different systems e. g. Na- or Mg-Ion.

3:00 Beyond Lithium, Novel Lithium Sulfur System and Lithium Superoxide

Khalil Amine, PhD, Manager, Advanced Battery Technology, Argonne National Laboratory

3:20 Conversion-Type Active Materials & Processes for Safer, Higher Energy Density Batteries

Gleb Yushin, PhD, Professor, School of Materials Science and Engineering, Georgia Institute of Technology

Energy density and cost of Li-ion batteries (LIBs) based on conventional intercalation compounds are closely approaching their limits. The reliance of conventional cathodes on the use of toxic metals additionally endangers health and safety of miners in developing countries. Conversion-type active materials offer an opportunity to double energy stored in LIBs, reduce their cost by the same factor, and improve cell safety. These materials may be produced from safer, cheaper and globally available resources and contribute to accelerated adoption of electric transportation.
