Up to date consumer manuals launched by Nio embrace a brand new 150-kilowatt-hour semi-solid state battery pack alongside the present battery varieties. The solid-state batteries will probably be out there on the Nio ES6 in China beginning in July, as per Nio CEO William Li.
In solid-state batteries, strong electrolytes – the charge-carrying elements between the 2 electrodes – are used as an alternative of liquid or polymer gel electrolytes in present lithium-ion or lithium polymer batteries.
A number of corporations have introduced investments in solid-state battery know-how for its benefits over lithium-ion batteries – they’re thought of extra vitality dense and quicker charging whereas utilizing the identical bodily area.
The doc reveals that Nio’s new 150 kWh battery, equipped by Beijing WeLion Power Know-how, suggestions scales at 575 kilograms, 20 kg heavier than CATL’s 100 kWh packs extensively out there on Nio fashions. But it surely affords an vitality density of 261 watt-hours per kilogram, 44.44 p.c greater than CATL’s unit with 180 Wh/kg.
That stated, there are 384 cells within the pack, a lot greater than the 96 cells within the CATL unit. The vitality density of those new cells is 360 Wh/kg, as per beforehand shared data by WeLion, reported Cnevpost.
On the Nio Day occasion in January 2021, when the Chinese language carmaker introduced its flagship ET7 electrical sedan, the model additionally unveiled the aforementioned solid-state battery, claiming it will ship over 1000 kilometers (620 miles) of vary.
SUVs aren’t as aerodynamic as sedans, and are prone to be heavier, which is likely to be the explanation why the ES6’s estimated vary is barely decrease at 930 km (577 miles). Future Nio sedans may have the ability to ship over 600 miles vary with the brand new solid-state pack.
Though the vary figures may differ relying on the area and testing cycles.
The model reportedly confronted challenges in scaling up and attaining price parity with the present battery know-how, which could possibly be the explanation why we’re seeing a niche of over two years between the announcement and deliveries.
Stable-state batteries might change into mainstream sooner or later as an growing variety of automakers are on the lookout for methods to democratize them.
Just lately, Toyota claimed its technological breakthrough might end in a solid-state battery able to delivering 745 miles vary, with a charging time of simply 10 minutes.
