Battery Analytics Tutorial Course 1/3: Battery Analytics and the Role of the BMS
This one-hour course will explore how various energy storage industry experts define the term “battery analytics.” It will also examine how the battery management system (BMS) is used to control the battery and provide real-time performance reporting, the lowest level of battery analytics.
This webinar will focus on the following key topics:
• The different types of battery analytics
• How a BMS works and why it is the most basic component of any battery analytics platform
• Real-time performance algorithms as the lowest level of analytics

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

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

Lithium Ion Capacitors – Combining Energy with Power
FREE Webinar – JSR Micro, Inc. is a proud sponsor of this event.
Lithium Ion Capacitors (LIC) are hybrids of electric double-layer capacitors (EDLCs) and lithium ion batteries (LIB). Combining the reversible non-Faradaic cathode from an EDLC and the reversible Faradaic anode from an LIB results in an ultra or super capacitor with significantly increased energy density, improved float performance and low self-discharge rates. Avoiding the lithium metal oxide cathodes from LIB’s improves the inherent safety and eliminates Cobalt content, however still combines aspects of energy & power of both cell types. The Faradaic intercalation/deintercalation reactions at the anode are capable of generating a significant amount of charge, while the non-Faradaic electrostatic storage of the electrical energy formed at the interface of the electrode and the electrolyte, known as an electric double layer, results in fast charge and discharge capabilities for hundreds of thousands, if not millions of cycles.
This webinar will focus on the following key topics:
• What is an LIC? Technology Introduction
• Key Benefits
• Safety
• EDLC vs LIC
• Applications
