Breakthrough Solid State Battery — 900 Wh/L Samsung [2020]
Samsung research was led by Yong-Gun Lee for an All-Solid-State-Battery (ASSBs). Their goal was to eliminate dendrites formation and increase coulombic efficiency.
To do that they sandwiched layers of Lithium Nickel-Cobalt-Manganese-Oxide (NMC for short) mixed with a Sulfide Solid Electrolytes (SSE, show formula on screen), on top of nanocomposite-layer of Silver-Carbon.
All of this is located in between a foil of Aluminum and Stainless steel as the current collectors.
The idea behind this was to remove lithium foil from the mix and have all lithium atoms part of the NMC and SSE. This approach diminishes the costs of the overall battery manufacturing since handling lithium usually needs an oxygen free environment due to its high reactivity.
This is important for a few reasons, in conventional lithium batteries, the anode comprised of lithium moves freely towards the positive electrode during discharge.
Dendrites are formed during the charging process when lithium moves back to its initial location thanks to the free movement enabled by liquid or gel electrolyte.
This is the main limiting factor of how much energy can be store in these batteries since to control this, the amount of lithium available in the system has to be caped, limiting the energy density.

Supercapacitors explained — the future of energy storage?



Go to brilliant.org/Undecided you can sign up for free. And also, the first 200 people will get 20% off their annual premium membership. Supercapacitors explained — the future of energy storage? With Tesla’s battery day event not too far off, and their acquisition of Maxwell Technologies last year, I thought it was worth taking a closer look at what a supercapacitor is. Some believe that supercapacitors might be integrated into future EVs. But, what exactly is a supercapacitor? And what makes them so different from batteries? Are they really the future of energy storage?

The Future Of Energy Storage Beyond Lithium Ion



Over the past decade, prices for solar panels and wind farms have reached all-time lows. However, the price for lithium ion batteries, the leading energy storage technology, has remained too high. So researchers are exploring other alternatives, including flow batteries, thermal batteries, and gravity-based systems.
CORRECTION (March 14, 2020): At 12:53 we incorrectly identify the size of the energy storage market. Overall, the energy storage market is predicted to attract $620 billion dollars in investments by 2040.

The Future of Energy Storage — Professor Yet-Ming Chiang, MIT



What have been the key battery technology breakthroughs to get us to where we are now? What are some new opportunities for large-scale energy storage & what's MIT doing? What are some key lessons for startups to be successful in the battery industry?
Energy storage will play an increasingly important role in a decarbonized world. From electric vehicles to grid resiliency, batteries will impact the ultimate success of numerous industries that are critical to a low carbon society. Professor Yet-Ming Chiang, one of the world’s most prominent researchers in energy storage, will give a personal perspective on some of the challenges and opportunities for better and cheaper energy storage.
From a historical perspective, battery performance has improved steadily, but now the divergent needs for batteries in high energy density applications such as EVs (and, coming soon, electric aviation), and those for grid storage, which emphasizes ultra-low cost and earth-abundant materials, are becoming clear. He will give examples of emerging innovations that may address these different needs, including solid-state and other batteries that use alkali metal electrodes, and approaches that make use of the most widely available electroactive elements. The expectation is that the audience will come away with a realistic but exciting roadmap of possible areas of innovation for energy storage.
Finally, he will conclude with his personal experiences in building battery enterprises. Battery technologies are notoriously difficult to scale given high technology risk and high development costs. Yet-Ming will share some of the unique lessons learned at startups he has co-founded, including A123, 24M, and most recently Form Energy.
Prof. Chiang's research focuses on the design, synthesis, and characterization of advanced inorganic materials and related devices. Current topics include new cathode and anode materials for lithium ion batteries, phase transformations in electroactive materials, electrochemical device design, electrochemical-to-mechanical energy conversion, self-assembling colloids, and the stability and defect chemical properties of interfaces in inorganic materials.
