Lithium Ion Capacitors – Combining Energy with Power

Wednesday, April 19, 2017 | 10:00 a.m. EDT USA / 4:00 p.m. CET Europe / 10:00 p.m. China

Duration – 1 hour

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

A PDF copy of the presentation will be sent to all attendees after the event.

What can we Learn From Thermodynamics of Lithium Ion Batteries?

Wednesday, May 03, 2017 | 10:00 a.m. EDT USA / 4:00 p.m. CET Europe / 10:00 p.m. China

Duration – 1 hour

Entropymetry is a new science and technology applied to lithium ion batteries. Battery temperature varies constantly owing to changing environment temperature and battery operation. At a cell rest the open-circuit voltage (OCV) varies linearly with temperature, the slope of which is proportional to entropy. Enthalpy can also be derived at any state of charge (SOC) or OCV of the cell. Analysis of entropy and enthalpy profiles teaches on the battery chemistry and on many of key cell states, including SOC, state of health (SOH) and state of safety (SOS). The electrochemical thermodynamics measurements (ETM) technology developed helps improve the accuracy of battery states assessment and battery performances including energy density and life. All these aspects will be presented and discussed.

This webinar will focus on the following key topics:

• Battery thermodynamics data measurements: Fundamentals and Methods
• Entropy and enthalpy profile of typical anode and cathode materials: phase diagram
• Entropy and enthalpy profile of typical lithium ion cells
• LIB Cell chemistry, state of charge, state of health and state of safety
• Using thermodynamics to improve LIB performance

A PDF copy of the presentation will be sent to all attendees after the event.

Understand and Prevent Battery Fires and Explosions – and Avoid Costly Failures Like the Samsung Note 7

Wednesday, May 24, 2017 | 10:00 a.m. EDT USA / 4:00 p.m. CET Europe / 10:00 p.m. China

Duration – 1 hour

Modern batteries (eg Li-Ion) contain hazardous chemicals & they heat up during use: this combination always has the potential to cause fires & explosions. This presentation will focus on improving the understanding of how these incidents occur, what can be done to avoid them & how the risk can be minimized during early stage design.

The Samsung Note 7 phone & Boeing Dreamliner airplane fires are very costly examples of how even large corporations fail to understand the potential fire risk of batteries.

The solution lies in knowledge of heat generation rate during normal use & information about safe boundaries such as temperature, discharge rate & overcharge, in realistic situations that represent actual use conditions. Data from commercial batteries of different types 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 & explosions occur
• How to design safer batteries though 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

A PDF copy of the presentation will be sent to all attendees after the event.
