See, now that is what might be putting a lot of people off buying an EV. The thought that you have just parked your brand new EV on the drive and someone invents a new battery which immediately makes your new car obsolete and worthless !

If I ever decide to go EV, think it will be down the lease-hire route.

Has to be the only sensible route.

mine is leased-hired as are most EVs too expensive to buy outright 2 years time I get another EV with the latest tech

Sorry I'll believe it when I see it in full scale production.

Triples energy??? Strong sell of marketing BS there.

It's not even a new idea. I am sure if it was a practical and feasible idea it would have been developed by now.

High-performance lithium battery anodes using silicon nanowires - Nature Nanotechnology

There is great interest in developing rechargeable lithium batteries with higher energy capacity and longer cycle life for applications in portable electronic devices, electric vehicles and implantable medical devices1. Silicon is an attractive anode material for lithium batteries because it has...

PS: silicon has long been the holy grail of Anodes due to it's very high energy density.
Panasonic, Tesla and others are working on an encapsulation technique to get around the high expansion and fracturing problems with Silicon. I expect pretty fast success on those techniques because the do not require any special processes.

I suspect the next major anode breakthrough will be solid state anodes and Quantumscape is a better bet than SINANODE's silicon nanowire option.

I must email the company involved and tell them they are onto a loser as Gromett on motorhome fun says so.

I have been following batteries for quite a while now. Pretty much every month there is a major breakthrough announcement like this and for as long as I can remember none of them have happened.
All we have seen is consistent and progressive 7% incremental improvements on average each year. I have never seen a tripling of capacity from a single mass market product.

The only time there has been a massive provable increase in storage density has been a major change in chemistry such as from NiCad to NiMH to Li. Or fantastic products that cannot scale such as Diamond Batteries using nuclear waste. Remember the 10,000 year battery?

Call me jaded but I am fed up of companies getting on the battery bandwagon, making big claims, raising big finance rounds then hearing nothing more from the product.

My prediction is that the next big things will be encapsulated silicon fragments followed by solid state and I am not convinced about solid state just yet.

I am not saying it won't work or can't work. I am simply saying...

I'll believe it when I see it in full scale production.

I have long got disenchanted with getting excited about bold claims such as these which end up fading into the past without anything more being seen.

Now if musky was announcing this, grom would be be singing a different tune to bs.

Nope, If he had announced this I would be wondering what he had been smoking (Again).

I am an optimist for people with track records, but not to the extent of believing things like this, even from Musk.

For the past 20 years, we've not had a major breakthrough in lithium ion battery technology. That's not to say they've not come a long way. There have been hundreds of improvements to make them more energy dense, charge faster and last more cycles, but it's been incremental changes all the way.
