Li-ion represented more than 80 of the installed power and energy capacity in the United States. Li-ion is the technology of choice because its ready now and commercially available. Electrochemical Energy Storage Lithium Ion-85 of the new capacity stationary applications.-Short duration - 0.5- 10 hours -Energy is available within seconds .-NMC LFP most widely utilized Utility Applications-Frequency regulation, load shifting, -Bulk renewable power management.-Micro Grid -Behind-the-meter BTM batteries EV Battery Chemistry Global stock of electric passenger cars ∼ 5 million Lithium Ion Materials Balance cell safety energy density range. Space saving- more cells less modules. Thermal Cooling Theoretical capacity NMC 622- 280 mAh/g Practical - 250 Wh/kg Pack level - 350wh/kg Source Roadmap integrierte Zell und Batterieproduktion Deutschland , 2016 Conversion- reaction cathodes Sulfur Li2S and oxygen Li2O. -Li plating and stripping issues. -SEI formation volume change Conversion electrodes Si, Sn, Sb, Ge, P Volume changes, particle pulverization, continuous formation of SEI lithium loss Increase Voltage Unstable with organic electrolytes at 4.3 V Solid electrolytes offers stability Increase Charge Increasing charge capacities of both the anode cathode Ultra Low Cost batteries Source Roadmap integrierte Zell und Batterieproduktion Deutschland , 2016 - Sulfur Sodium are cheap, abundant high energy density elements - Air-breathing aqueous sulfur flow battery - Wind and solar displace carbon intensive through cost-effective electrical storage. - To be comparable to natural gas, batteries have to cost less than 20 per kWhr. Conclusions ● Progress in energy Storage will have major impact on society ● Li-ion market shift into grid storage. ● Reduction of cobalt in existing chemistries, aiming to reduce cost and increase energy density, currently best solution to reach 300Wh/kg ● Novel materials with new reaction mechanism is important for beyond lithium. ● Solid state lithium will move the industry to 1000Wh/l ● Increasing wind and solar deployments will drive the development of new ultra low cost battery chemistries based on earth abundant elements Any questions Cormac O’Laoire, Electrios cormacelectrios.com 852 6171-6010
