  Advancing Mining Processes to Make Better Materials for Use in Lithium Ion Batteries

  American Manganese Inc has developed a low-cost, environmentally friendly hydrometallurgical process to recover manganese (Mn) from lower grade resources. American Manganese has applied for a patent for their hydrometallurgical process that produces electrolytic manganese metal with low energy and water consumption. American Manganese commissioned R&D contractor, Kemetco Research Inc to determine uses of Artillery Peak manganese resource material to generate high value alternative products. Chemical manganese dioxide (CMD) and lithiated manganese oxide (LixMn2O4) for use in rechargeable batteries were the areas researched.

  The research was successful in producing CMD from Artillery Peak resource material with low cation impurities and avoiding processing steps that are known to introduce metallic impurities in the final product. Cation impurities cause capacity fade, whereas metallic impurities are known to cause catastrophic failures (such as fire and explosions) in lithium ion batteries. Working rechargeable lithium ion coin cell battery prototypes were produced from the CMD material.

  This webinar will focus on the following key topics:

  • Catastrophic failure of Li Ion batteries caused by metallic impurities that may be introduced from the mining of raw materials
  • Conventional mining process to recover MnO2 used to make LiMn2O4
  • Research on a new mining process that avoids steps known to introduce metallic impurities to recover MnO2 used to make LiMn2O4

  Solid Electrolytes and Bulk Scale Solid-State Batteries

  Recently, the push to move beyond Li – ion battery technology has grown. Several advanced battery technologies & chemistries have been identified as promising candidates including i) solid-state batteries with Li metal anode, ii) Li – S chemistries, iii) Li – air(oxygen), and iv) flow batteries. Although an engineered solution using liquids may be possible for some of these options, a solid electrolyte is an enabling technology for each of these beyond Li – ion alternatives. This webinar will introduce the operating principles of each of these cell technologies and solid electrolytes will be discussed in this context. The requirements of a solid electrolyte will be outlined & several state of the art solid electrolytes will be compared. Recent technical progress towards the fabrication of solid-state batteries will be reviewed. Finally, an overview of market applications for solid-state will be presented.

  This webinar will focus on the following key topics:

  • Overview of beyond Li – ion battery technologies enabled by solid electrolytes
  • Comparison of state of the art solid electrolytes
  • Recent technical progress towards solid-state batteries
  • Review of market applications for solid-state batteries

  Energy Storage RTE Tutorial Course 3/3: Total Battery System RTE – Ranking and Comparison of Different Battery Chemistries

  RTE impacts of HVAC/Ventilation and Inverters will be described. Batteries generate heat, and this must be dissipated by system cooling and/or taken out of the system. Heat generated can be calculated by looking at IR heating and that generated (net) by exothermic reactions. Examples will include LFP, Li-NMC, Lead Acid and Nickel batteries, both when they are fresh, as well as at their end of useful life. The overall ancillary equipment energy usage will be listed for these systems, and a % RTE loss will be calculated for both nominal rate and high rate applications. Commentary will be provided for other systems. RTE will be summarized and ranked for most energy storage battery chemistries including ZA, NaS, LiS, Saltwater, Liquid Metal, Zinc Bromine and Fuel Cells.

  This webinar will focus on the following key topics:

  • RTE impacts of Inverters and HVAC
  • RTE impacts for ancillary equipment for different systems
  • RTE numbers for most battery systems being considered for energy storage

  Stability of Li7La3Zr2O12 Garnet Solid-State Electrolyte Against Metallic Lithium

  Energy storage demands will require safer, cheaper and higher performance electrochemical energy storage. While the primary strategy for improving performance has focused on state-of-the-art Li-ion batteries, this work seeks to develop solid-state batteries employing metallic Li anode. Recently, the ceramic electrolyte, Li7La3Zr2O12 (LLZO) cubic garnet, has shown promise owing to its unique combination of properties such as high Li-ion conductivity and electrochemical stability. Generally, LLZO is synthesized through powder processing and sintering at high temperature to produce dense membrane. Processing of the ceramic materials produces internal and surface flaws which will inhibit lithium transport creating localized current density and control the stability against Li dendrite propagation. This presentation will discuss new improvement in methodology to evaluate the integrity of LLZO membrane.

  This webinar will focus on the following key topics:

  • Methodology to evaluate the integrity of LLZO by identifying the microstructural flaws and their impact on mechanical properties
  • DC cycling, EIS, XPS will be shown to determine the reactions that govern the maximum current density
  • Correlate the electrochemical stability and critical current density with defects in polycrystalline solid state LLZO electrolyte
