Energy Storage: Batteries, Supercapacitors, Lithium-ion Capacitors

This session is concerned with energy stored electrically, with particular emphasis on:  

»lithium-ion batteries
»new "post lithium-ion" batteries that may follow
»lithium-ion capacitors
»supercapacitors

There is a close look at the technologies, how they may improve over the coming ten years and what that makes possible in market growth. Will silicon anodes replace graphite and even the later titanium dioxide ones? Which cathodes are winning and what comes next? What are the costs of the battery parts and where is that going?

We examine uses and new options for serving them such as low power transparent, flexible, woven or even stretchable versions as needed for the new wearable electronics. Electric vehicles will become the largest market for lithium-ion batteries so IDTechEx looks at market penetration of over 45 categories of hybrid and pure electric vehicle by land, water and air. This is a level of detail only IDTechEx can provide. We look at how battery cost is becoming a smaller percentage of electric vehicle cost but still dominant and we forecast the improvement in parameters expected to 2025. We show which parameters are important in which applications. For example, safety and weight are crucial in the new electric aircraft.

The situation with supercapacitors is complex. As with lithium-ion batteries it is not good enough to create a better electrode: it must be matched to a better electrolyte and there is a trend to ionic, non-toxic organic or aqueous electrolytes. We compare exohedral active electrode materials such as graphene with the traditional hierarchical ones with progressively smaller pores into the solid. Parameters are compared. We then look at what will be achieved with energy density and other parameters in the next ten years and what share of the lithium-ion battery market will be impacted. Lithium-ion capacitor hybrid devices now achieve one million cycles of life and energy density up to 80 Wh/kg experimentally. How does pseudocapacitance help these figures? Supercapacitors have taken some market share from lithium-ion batteries despite one hundredth of the energy density. That gap will reduce and it may increase market share disproportionately due to their superior safety, life, reliability and so on.

That is not the whole story because another alternative to lithium-ion batteries is the "post-lithium-ion" battery notably lithium-metal rechargeable in its various forms or rechargeable batteries based on other metals. We examine this work and its potential.

The trends in the functional materials employed are examined closely to look for potential for companies making formulations and intermediate materials. For example, there is the trend from liquid electrolytes to gel then solid ones. There is the trend to replace toxic electrolytes such as acetonitrile and potentially expensive materials such as cobalt. We also look briefly at the new high-speed low-weight flywheels which have supercapacitor-like energy capture and release (power density) and may charge supercapacitors or batteries.

Finally, we report extensive work on structural electronics where the body of say a car will be a load-bearing supercapacitor or battery, potentially with 15% greater range and greater reliability and space as a result.

Electrical energy storage. Definitions, comparisons, market size.
Compiled by Dr Peter Harrop, Founder, Chairman, Principal Analyst, IDTechEx.
 
14:15 - 14:30
Lithium- ion rechargeable batteries
Compiled by Franco Gonzalez and Dr Peter Harrop
    Lithium-ion batteries dominate for the coming decade - anatomy (anode, cathode, electrolyte, separator), chemistry overview and constructional options (rolled vs pouch vs prism). Issues overview: safety, toxicity, affordability, benefits. Competition fights back - advanced lead acid etc.
 
14:30 - 15:00
Applications timeline and what is replaced in the marketplace. What is replacing lithium-ion batteries and why.
    »Timelines of improvements and competition.
    »Current carriers - copper, aluminium, pre-coatings: what/why? Fillers and enhancers in active electrodes.
    »Graphite, titanium dioxide and silicon anodes to replace graphite and even the later titanium dioxide ones.
    »Many complex cathode options: comparison and timelines
    » Separators, electrolytes.
    »Relative costs of the battery parts and trends.
    »Lithium-ion forecast
 
15:00 - 15:20
Break
 
15:20 - 15:50
Post-lithium-ion batteries.
Compiled by Franco Gonzalez, Senior Technology Analyst, IDTechEx
    Lithium-metal eg lithium-water, lithium-sulfur, lithium-air. Magnesium, sodium etc batteries. For each of these we will cover: researchers, results, future, investor views, downgraded projects and the new emphasis.
15:50 - 16:50
Supercapacitors, hybrid supercapacitors
Compiled by Franco Gonzalez and Dr Peter Harrop
    »Pure supercapacitor vs pseudocapacitance-enhanced vs hybrid supercapacitor vs lithium-ion battery.
    »Construction (current carriers, active electrodes, electrolyte, separator), uses, technology and application timelines.
    »Improvements in energy density (replacing batteries) or ac performance/ time constant (replacing tantalum and aluminium electrolytic capacitors).
    »Exohedral active electrode materials such as graphene compared with the traditional hierarchical ones with progressively smaller pores into the solid.
    »Matching new electrode to new electrolyte.
    »Pseudocapacitive electrolyte or electrode - parameters are compared.
    »Energy density forecast and other parameters in the next ten years and what share of the lithium-ion battery market will be impacted and why.

    Supercapacitor and supercabattery (hybrid supercapacitor) applications now and in 2025

    Today's main applications of supercapacitors, Pb-C hybrid supercapacitors and Li-ion capacitors. Other partly faradaic options. Applications timeline and what is replaced in the marketplace. On the other hand, what is replacing supercapacitors and supercabatteries and why.
16:50 - 17:15
Overview
Compiled by Raghu Das, CEO and Principal Analyst, IDTechEx
    The burgeoning adoption of large batteries. New examples: electrifying ships, Tesla house batteries, high power energy harvesting.

    Future energy storage that is transparent, flexible, woven, stretchable or structural. For example, the supercapacitor printed circuit board, cable cladding, e-textile and car body. Co-deposition with photovoltaics etc.

    Compare batteries and supercapacitors with high-speed lightweight flywheels for high power density with storage. All-mechanical vs electric.
