Avoid Battery Explosions and Fires – With Right Data and Better Designs
Modern Li Ion batteries contain hazardous chemicals and heat up during use – this combination always has the potential to cause fires and explosions. This presentation will focus on improving the understanding of how such incidents occur, what can be done to avoid them and how the risk can be minimized during early stage design.
The solution lies in knowledge of the heat generation rate during normal use, and information about safe boundaries such as temperature, discharge rate & overcharge in realistic situations that represent actual conditions of use. Data from commercial batteries of different types, including videos of batteries undergoing thermal runaway, will be used to illustrate these points.
A relatively new technique will also be discussed with data, which allows total heat output during discharge to be measured on-line and this can be used both for design and battery modelling. Examples of the data will be provided.
This webinar will focus on the following key topics:
• Why battery fires and explosions occur
• How to design safer batteries through understanding of heat generation
• Video evidence of batteries under explosive conditions
• How better thermal management systems can be designed – based on heat measurement from isothermal calorimetry
• Laboratory instruments suitable for testing and data generation

Certification Challenges for Secondary Use EV Batteries
As the 1st generation of Lithium-ion based hybrid and battery electric vehicles are reaching end-of life, or original traction batteries are being replaced with new batteries, the interest in secondary life or repurposing of these batteries continues to grow. Lithium-ion batteries present several challenges to Auto OEM’s, Recyclers and waste operators. Repurposing of EV batteries for non-automotive applications also creates new challenges for certification and acceptance by AHJ’s (Authorities Having Jurisdiction). This webinar discusses the current market challenges and concerns, while providing a roadmap of the current options for various usage cases of reused or repurposed EV batteries.
This webinar will focus on the following key topics:
• Understand the usage cases for secondary life batteries
• Review market drivers for secondary use batteries
• Review the concerns of battery and cell manufacturers with re-use of lithium-ion batteries
• Discuss the unique challenges to certifying used batteries for new applications
• Discuss current options for certification in the US market

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
