New battery technology

[CrewOVtwo]

Did anyone else catch the news that battery technology is about to take a gigantic leap forward?
It appears the leading manufacturer of batteries (CATL) has made a discovery that looks like a real game changer.
It apparently involves sea water 😯

It’s still in development but CATL are an impressive company. Here’s a write up:

It's sounds like a leclanche cell😁😁

 

[ProfJohnL]

Yes in many ways it does, except its using very different materials, and it has a much greater power density.

I wonder which sea they will get the water from,the Cumbrian coast,sea of Japan or the Mediterranean sea?

Where does all the electricity come from? All the battery tech in the world is not going to solve the energy supply side. It still takes a given amount of energy to move a car of a given weight at a certain dpeed. All a battery does is act as a store of energy produced elsewhere. In itself a battery doesn’t produce anything.

However, if better battery storage existed, spare wind, solar or hydro capacity can be stored instead of wasted as it is at the moment.

I guess the fuel tank doesn’t do anything except store a source of energy also produced elsewhere.

I'm not sure if you are using this statement for or against EV's?

I suspect against.
But the antipathy to EV is still well founded but in say a few years time may well be unfounded😉

As an owner of two EV pedal assist bikes, two EV mowers, numerous E tools , brilliant.
My personal issue all this EV thing is being pushed far too hard in too short a timescale without due regard to a decent charging infrastructure. Affordability for everyone hasn’t been fully allowed for.
I see the used value of a 3 year old EV is circa 35% of its original price.🙀

How sad the most affordable EVs are from the East , not Europe. Is that good🤔

My Grandson has recently acquired a new model Tesla Y, two neighbours have EVs and during discussions none had concerns over charging infrastructure, although commercial charger prices could be expensive. But all three do most of their charging at home, which more than compensates for the extra costs of using commercial chargers.

I don’t think many realise how many chargers there are out and about, you just don’t see them as easily as petrol stations. and the number are increasing month on month. The real issue in my mind is the restrictions faced for caravaners with reduced range and the time/ inconvenience of charging when towing. If you want to make it work you can do, but much depends on the individual’s preferences, touring journey length, and ratio of solo and towing journeys.

Electric boost: EV chargepoints in the UK grow by 27% in a year

News follows last week’s announcement that drivers will soon enjoy discounts of up to £3,750 on new electric cars.

It can work for some people's usage pattern - but not for others, however much they may want to make it work.

Exactly my point. For caravanners it’s more difficult compared to solo driving.

I can read Flatcoats statement at #6 both for and against EV's. I can't assume a particular bias, I prefere Flatcoats's opinion direct.

EV pedal bikes and lawn mowers and other tools and toys do not have the same specific charging needs as EV's, so it's illogical to use their deployment and idiosyncrasies as an analog for the introduction of EV's and or the EV charging infrastructure.

Market forces! I'm sure that if you search hard enough and you could find a model of an ICE car that has suffered similar depreciation! I'm pretty certain part of the reason for a wider range of EV's having such dramatic depreciation is at least in part due to bulk buys of EV's by finance firms, which then dumps them on the secondhand market when ther PCP and leases expire.

Alos there has been so much distrust EV messages put about by the oil related industries that some mud has stuck There is no technical reason why the vast majority of EV's should have lower values than equivalent ICE.

No its not good, its been greed by man car manufacturers who make much lower profits on mass market vehicles compared to halo designs. SO they start with the most expensive models and then only later introduce the simpler and cheaper products for mass markets.

And being pedantic as usually I am, most car manufactures wh osell into the UK are actually located to the East of the UK even those in Europe!
