Settemila euro per una EV di massa con batterie al sodio

[Roberto Deboni DMIsr]

Mentre in Italia Salvini vuole bloccare il progresso,
in Cina ha una piccola sconosciuta (Hina) con le sue
batterie al sodio:

"The battery, developed by Beijing-based Hina Battery
Technologies, could help reduce the cost of EVs by 10 per cent"

Le batterie hanno minori prestazioni di quella al litio, ma
costano meno, tanto da incidere un -10% sul prezzo globale
di un auto.

"China’s JAC Group has unveiled the world’s first electric
vehicle (EV) powered by a cheaper sodium-ion battery."

"The battery, which could help reduce the cost of EVs by 10 per
cent, was developed by Beijing-based start-up Hina Battery
Technologies. The JAC EV, a demo car, is fitted with a
25 kilowatt-hour (kWh) battery that can go as far as
250 kilometres on a single charge, Hina said in a statement."

Con quella autonomia (e anche le dimensioni) e' una utilitaria
da citta'.

"Sodium-ion batteries use cheaper raw materials and can offer
EV makers an alternative to existing technologies that rely
on lithium and cobalt as the main ingredients."

"Such batteries have lower density than their lithium-ion
counterparts. Their energy density of 140 watt-hours (Wh)
per kilogram is lower than that of lithium-ion batteries
which use nickel, manganese and cobalt as ingredients.
Lithium-ion batteries have a higher capacity ranging
from 240Wh to 350Wh per kg. But sodium-ion batteries have
advantages such as low-temperature performance and
charging speed."

Ahhh, di striscio, la Nio ha deciso di imitare Tesla, sia
nel produrre in proprio le batterie, sia nella tecnolgia
delle grosse celle cilindriche introdotte da Tesla.
