It seems strange that an independent YouTube channel like the Fully Charged Show is better educated on hot topics like batteries and electric vehicles (EVs) than politicians and commentators, but that’s the reality.
In fairness, as time goes on technological advancements (in any number of sectors) are accelerating at a mind-melting rate, so how could a ‘generalist’ hope to understand what’s happening in the here and now, and what it means for the near future?
And that’s what politicians are: generalists. People who have to absorb reams of information, and are often parachuted into areas (seriously) outside their expertise.
It’s entirely possible that those key policy-makers are hopelessly out of date on matters like artificial intelligence and battery chemistries.
What’s more, there are more than a few who are so extensively entwined with vested interests from establishment organisations that it might not suit them to have their finger too firmly on the pulse of new technologies.
On the subject of generalists, journalists are little better – and often worse when it comes to misinformation.
I’ve been communicating the benefits of ‘cleaner’ technologies for more than two decades; when I see our specialist subjects (energy and transport) being discussed by politicians or commentators, my mouth is generally agape as I listen to a torrent of untruths.
I think it’s safe to assume these inaccuracies are not limited to the topics in which we specialise. A worrying thought.
The misinformation we have witnessed from the ‘mainstream media’ in 2023 seems to have plumbed the depths more profoundly than we can recall.
We speculate that the surging global demand for wind, solar, batteries, heat pumps and EVs of all shapes and sizes is really rattling a fossil fuel establishment that has had its own way for too long.
We’ve heard it all before, but the intensity of the FUD (fear, uncertainty and doubt) being pumped into public discourse right now is a reminder of the power of dirty tricks, outright lying, obfuscation of facts and arguably the most insidious of all: the billions spent on lobbying and influence.
We have enough experience to be able to counter all the arguments we hear, but it takes time – and that, of course, is the reason why it is such an effective tactic.
The biggest catalyst of change in energy and transport though is obvious: the lithium-ion battery.
An almost accidental investment by Exxon in the early ‘70s, the lithium (titanium disulfide) battery breakthrough was gathering dust until Sony saw the potential of a similar chemistry for rechargeable lithium cells for camcorders in the early ‘90s.
This in turn led to a limited-edition EV from Nissan in 1998. Then followed GM’s infamous EV1, a model that relied on nickel-metal hydride batteries and in turn inspired Tesla’s Roadster, which reverted to lithium-ion.
The rest is history, yet the ‘chemistry’ of these batteries continues to evolve. In fact, many argue that we are still merely scratching the surface of the battery’s potential.
Much like the rapid reduction of cost and increase in computational power that revolutionised the microprocessor industry in Silicon Valley, variants of lithium-ion batteries have been undergoing a revolution of their own.
Four times more energy dense and 97% cheaper than that early Sony technology, rechargeable batteries have – much like wind and solar – ambushed the fossil fuel industry.
What’s more, progress continues at pace, and several firms are on the cusp of unlocking batteries that are twice as efficient again.
This is why we’ve seen battery electric vehicles leap from 80 miles of range to 250, and could easily witness a doubling by the end of this decade. Possibly sooner, much sooner.
The volumes of investment in energy storage are so high that we will likely witness multiple technological leaps in the next few years, and levels of efficiency that might make medium- to long-haul electric aviation a realistic prospect.
In spite of this fantastic progress, some still prefer to pretend batteries are fundamentally flawed, and spread unsubstantiated bad news about the prospects of an electrified future.
The truth is that while there are many mainstream media hit pieces on the ‘availability of lithium’ and the ‘ethics of cobalt’, any obsession with individual materials is pointless. There will be many different battery chemistries.
It’s cobalt that has invariably been cited as an issue, with deeply emotive images of child labour in the Democratic Republic of the Congo (DRC) often used to inflame opinions and outrage.
But the uses (see below) of cobalt pre-dated its use in battery electric vehicles, and those uses will continue long after the electric car market has engineered its way round the need for cobalt.
This isn’t the stuff of fantasy; Tesla, Ford, Rivian and Stellantis are all using incredibly large volumes of cobalt-free LFP batteries (lithium iron phosphate) right now, and are in the process of phasing out the use of cobalt entirely.
Well, what about lithium? No, it’s not all that rare. Yes, scaling up its mining to match the demand for EVs will be a challenge, but not impossible. Yes, sourcing lithium can be ‘environmentally destructive’, but no, not always; there are non-invasive ways to extract it.
The process of sourcing fossil fuels is much worse; a battery electric vehicle is cleaner than an internal combustion engine (ICE) car after only 16,000 miles on even the dirtiest grid.
EV batteries will last much longer than engines, can be used in buildings after their first life and at the end of their second life can be recycled almost entirely, too. Petrol? No. Diesel? No. We just burn them into the atmosphere and hang the consequences.
In better news, cobalt- and lithium-free sodium-ion batteries, as pioneered by the likes of CATL, AMTE, LiNa, Faradion and many more, are already here, and will be in home and car batteries in the next 12 months.
As even politicians and journalists are likely aware, sodium is extraordinarily abundant and cheaper, too.
Believe us, this battery arms race is only just starting. Wait until you hear about semi-solid state batteries.
In short, batteries are better, and so are battery electric vehicles. In fact, batteries (and energy storage in general) will lead us to a more resilient, balanced energy system, where we can make greater usage of the planet’s finite resources.
Don’t believe the cobalt conspiracies and lithium lies that try to tell you otherwise. And ask yourself, if they are this inaccurate on batteries, what else have they got wrong? And are they even worth listening to in the first place?
At the Fully Charged Show, and at our Fully Charged LIVE events, we will always endeavour to keep you as current as we are.
