Samma sak gäller för solpaneler, vindkraftverk och inte minst kontaktledningar. Alla dessa tekniker har en återbetalningstid på några år, vilket är en bråkdel av deras långa livslängd. Batteridrift har fördelen att batterierna kan laddas när det finns ett överskott i elnätet. Kontaktledningsdrift kan ändå behöva batterier för energilagring när det inte blåser och solen inte skiner. Vidare är
nya batterikemier som Na-jon och Li-S mer resursmässigt hållbara.
NMC är ju på utgående.
How close are we to solid state batteries for electric vehicles?
Ars Technica skrev:They’ve also gotten really cheap, comparatively speaking. When Japan’s Sony Corporation introduced the first commercial lithium-ion battery in 1991, drawing on a worldwide research effort dating back to the 1950s, it powered one of the company’s camcorders and cost the equivalent of $7,500 for every kilowatt-hour (KwH) of energy it stored. By April 2025 lithium-ion battery prices had plummeted to $115 per KwH, and were projected to fall toward $80 per KwH or less by 2030—low enough to make a new EV substantially cheaper than the equivalent gasoline-powered vehicle.

In fact, says McCalla, the standard lithium-ion industry is so far ahead that solid-state might never catch up. “EVs are going to scale today,” he says, “and they’re going with the technology that’s affordable today.” Indeed, battery manufacturers are ramping up their lithium-ion capacity as fast as they can. “So I wonder if the train has already left the station.”

Still, says Louli, the long-term demand is definitely there. “What we’re trying to enable by combining the lithium-metal anode with solid-state technology is threefold,” he says: “Higher energy, higher power and improved safety. So for high-performance applications like electric vehicles—or other applications that require high power density, such as drones or even electrified aviation—solid-state batteries are going to be well-suited.”
Det satsas mycket på solid state-batterier, men
behövs tekniken? Fordon med vanliga batterier är billigare i Kina. Resten av världen väntas haka på om fem år.
Rho Motion skrev:Rho Motion, a Benchmark Mineral Intelligence company specialising in EV supply chain research and insights, reports that 2.1 million electric vehicles were sold globally in September 2025, the highest monthly total on record.
Som synes är befintliga batterier tillräckligt bra för att vinna marknadsandelar. Vidare utestängs fordon med förbränningsmotor i allt fler städer, inklusive bussar:

Stockholm behöver konkurrera med städer som Köpenhamn, Utrecht och London - den nya urbana medelklassen vägrar att bo i stadskärnor där utsläpp tillåts.
Netherlands: Zero-emission zones lead to boom in electric vans and trucks
electrive skrev:The Dutch ZEZ-F zones were introduced in January 2025 and now cover 18 cities. The effects are already clearly noticeable: according to Clean Cities, municipalities that have introduced ZEZ-F zones or simply border on such zones are seeing faster electrification and a significant decline in diesel vehicles. Diesel vehicles would thus be displaced from densely populated cities in particular.
This is particularly evident when looking at registration figures in a European comparison: in the first half of 2025, 78 per cent of new vans registered in the Netherlands were battery electric, compared to an EU average of only nine per cent. According to Clean Cities, sales of electric trucks in the Netherlands rose by 188 per cent compared to the previous year, accounting for almost one in five new electric trucks sold in the EU.
Hela 18 nederländska städer har infört så kallade nollutsläppszoner,
upp från 14 i början av året. I dessa är elbussar inte bara framtiden, utan redan en realitet!
