Is This Solid State Battery Breakthrough Too Late?

YouTube text:

Solid state batteries have been hyped for years as a silver bullet for making EVs mainstream, improving consumer electronics, and … well … everything. It’s 2022 and they still aren’t here in any meaningful way, but there have been interesting advancements that are worth exploring. However, with several other battery technologies popping up offering similar or better energy density, lifespan, safety, and costs, (all of which are solid state batteries’ big sales pitch) is solid state still the future of energy storage tech? Let’s see if we can come to a decision on this.

New 2022 Graphene Battery Launch – 8 Min. Charge, 560 km Range

YouTube text:

Graphene nanotechnology is set to be one of the most exciting and ground breaking technologies of the 21st century. Nanotechnology has already revolutionised medicine, construction and industry. And now graphene is about to become a reality in electric vehicle batteries, increasing energy density by 40% or more, and reducing charge times to just a few minutes. Is this the push we’ve been waiting for to move EVs into the mainstream?

Why The EV Industry Has A Massive Supply Problem

YouTube text:

8 mrt. 2022 The United States has a lithium supply problem. Lithium-ion batteries are in everything we use — in phones, laptops, tablets, cameras and increasingly cars. Demand for lithium-ion batteries has risen sharply in the past five years and is expected to grow from a $44.2 billion market in 2020 to a $94.4 billion market by 2025.

This is largely due to the boom in electric cars. Nearly every major automaker has announced a transition to electric vehicles. Tesla delivered almost one million cars in 2021, and electric vehicle companies like Rivian and Lucid are rolling new models off the line. In order to power all of these EVs, we will need batteries, lots of them. Electric vehicle growth will be responsible for more than 90% of demand for lithium by 2030, according to Benchmark Mineral Intelligence. This vital mineral in rechargeable batteries has earned the name “white gold” and the rush is on.

Former Tesla CTO and Elon Musk’s right-hand man, JB Straubel, started Redwood Materials in 2017 to help address the need for more raw materials and to solve the problem of e-waste. The company recycles end-of-life batteries and then supplies battery makers and auto companies with materials in short supply as EV production surges around the world. Straubel gave CNBC an inside look at its first recycling facility in Carson City, Nevada.

Cobalt also deserves a lot of attention because it is one of the most expensive materials found in lithium-ion batteries. Cobalt extraction is largely concentrated in the Democratic Republic of Congo, where it is linked to human rights abuses and child labor, while cobalt refinement is almost exclusively done in China, making cobalt part of a tenuous supply chain. These are some of the reasons why battery manufacturers like Samsung and Panasonic and car makers like Tesla and VW, along with a number of startups are working to eliminate cobalt from lithium-ion batteries completely.

Charging Your Devices Manually – How Much Time?

You can generate electricity manually, or “footily” rather, with a bike.

How much time does it take to charge the following devices:

– mobile phone: 15 minutes
– tablet: 30 minutes
– laptop: 1 hour
– car: 1 month

Few people realize how much energy a kWh is. One kWh is the amount of electricity, required to lift a sedan car to the top of the Eiffel Tower.

[deepresource] – One Kilowatthour

One Kwh is a day’s hard manual labor. On a bike in the gym, you can generate 100 Watt, easily… for half an hour. One kWh is ten hours. The modern European has per capita about 100 virtual grownup men, who 24/7/365 sit on a virtual bike and invisibly generate electricity. An American even has 150 of those energy slaves.

Should give you an idea of the severity of our energy predicament.


Borophene could replace graphene as the next super material, especially in the realm of batteries, electrolysis, capacitors and hydrogen storage.

Zinc Bromide Gel batteries Better than Li-Ion

YouTube text:

Energy storage is becoming an increasingly crowded market which, at least at utility scale, is still dominated by lithium-ion technology. But cheaper, greener and safer alternatives are being developed all the time. One of the latest candidates uses well established zinc-bromide chemistry but with a completely new twist, all wrapped up in very inexpensive and easily recyclable packaging from existing battery production lines. Very clever!

GE’s Molten Salt Battery Failure


In 2011, then-President Barack Obama visited a General Electric or GE facility in the town of Schenectady, New York. There, he mostly discussed wind turbine exports. But he also briefly mentioned an “advanced battery” business with great promise.

Obama was referring to a molten salt stationary battery technology branded as Durathon. GE CEO Jeff Immelt believed that it will become a billion dollar business.

But Durathon fell far short. In 2015, the company closed its battery manufacturing factory in New York after investing nearly $200 million. Nearly a hundred people lost their jobs.

In this video, we are going to look at General Electric’s failed molten salt battery business venture.

Note, the video is not an argument against molten salt storage, just GE’s business planning.

The World’s Largest Battery Isn’t What You Think

YouTube text:

Because of the intermittency of renewable energy like wind and solar power, storing large amounts of electricity is a necessity for the decarbonization of our energy system. However, we still don’t have enough batteries to compensate for renewable energy slumps across the planet. When thinking about the biggest utility-scale energy storage installations, a huge cylindrical lithium ion battery powered light bulb may go off in your head. But what if I told you the world’s largest battery taps into water rather than lithium? Can an old technology, even one still learning new tricks, be the answer? Let’s see if we can come to a decision on this.

E-Buses on Fire in Paris and Elsewhere

What’s 1 kWh? That’s the kinetic energy of a car, falling from the top of the Eiffel Tower:

[deepresource] – One Kilowatthour

An e-bus can have a battery with an energy content of 350 kWh, that’s a lot of energy. You can imagine that quite a firework can be generated from that amount of energy.

This could keep a lot of people, including me, to have reservations about installing a home battery inside your (paid-off) home.

Wie Klimafreundlich Sind E-Autos Wirklich? – Harald Lesch

All-German Post.

Wie klimafreundlich sind E-Autos? Dieser Frage geht Harald Lesch in einer neuen Folge von Terra X auf den Grund – mit teilweise verblüffenden Erkenntnissen. Er korrigiert sich damit selbst, hatte er vor drei Jahren im selben Format doch noch ein Plädoyer für Wasserstoff gehalten.
