Lithium-ion battery, How does it work?



A portable power supply has become the lifeline of the modern technological world, especially the lithium-ion battery. Imagine a world where all cars are driven by induction motors and not internal combustion engines. Induction motors are far superior to IC engines in almost all engineering aspects, as well as being more robust and cheaper. Another huge disadvantage of IC engines is that they only produce usable torque in a narrow band of engine RPM. Considering all of these factors, induction motors are definitely the perfect choice for an automobile. However, the power supply for an induction motor is the real bottleneck in achieving a major induction motor revolution in the automobile industry. Let’s explore how Tesla, with the help of lithium-ion cells, solved this issue and why lithium-ion cells are going to become even better in the future.

The truth about graphene — what's the hold up?



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. The truth about graphene. Ever since it was first discovered in 2004, graphene has been hailed as one of the most important breakthroughs in materials since the plastics revolution more than a century ago. The early predictions were that graphene would almost immediately enable the kinds of products and technologies that we're used to seeing in sci-fi movies. Cut to more than a decade and a half later and that still hasn't happened. Not even close. With opinions split between people overhyping graphene or calling it a massive disappointment, it's time we got to the truth of what is really happening with this so-called 'wonder material'.

Building a 3.5kWh DIY Solar Generator for $650 — Start to Finish



After having a friend ask several questions regarding a solar generator project he was working on, I decided this would be a good opportunity to build my own solar generator and fully document the process. The total build came out to around $641. This video provides an in-depth look at the process involved in collecting and assembling the battery pack along with the choice of components and some testing.

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.
