Two and a half years after first sharing plans to implement a 150 kWh solid-state battery pack in its EVs, NIO seems poised to lastly do exactly that. The automaker’s digital consumer manuals now function specs of the solid-state pack, provided by WeLion – debuting on the upcoming ES6 SUV. The extra helps latest guarantees from NIO’s chief that clients in China will be capable of choose the energy-dense pack as early as this month.
Throughout its 2020 NIO Day occasion, held in January of 2021, Chinese language EV automaker NIO unveiled a 150 kWh pack, that includes solid-state battery cells configured to the identical design of its present lithium-ion cells. On the time, the corporate was promising its new pack might ship 1,000 km (620 miles) of vary on a single cost.
Like many solid-state applied sciences we’ve coated in recent times, full-scaled commercialization at all times feels two years away. Whereas many battery builders have launched and even showcased much less risky and extra energy-dense expertise that simply bests lithium-ion chemistry, few have been capable of scale to a degree that gives price parity with the present cell customary.
NIO itself has confronted a number of delays in implementing the brand new pack in its EVs, to the purpose that we had type of brushed it off altogether. That modified this previous Might when the automaker made a submitting with China’s Ministry of Trade and Info Expertise (CMIIT), noting intentions to promote three current EV fashions with expanded battery capabilities supplied by solid-state battery developer WeLion.
Through the launch of NIO’s ES6 on the finish of Might, we discovered that the brand new SUV would be the first of these three EVs to supply the 150 kWh solid-state pack as an choice to clients. Following new particulars in its buyer guide, we’ve discovered the precise specs of this new pack, providing additional hope we could actually see it toll out in July.
NIO’s solid-state pack is over 40% extra power dense
Based on particulars in NIO’s EV consumer manuals identified by CnEVPost, the brand new 150 kWh solid-state pack is barely heavier however considerably extra power dense than the 100 kWh lithium-ion pack from CATL presently being provided to clients.
For instance, NIO’s solid-state pack weighs 575 kg (1,268 lbs), 20 kg (44 lbs or 3.6%) heavier than the 100 kWh packs (555 kg). Moreover, the brand new pack’s power density is 261 Wh/kg, 44.44% increased than the 180 Wh/kg the 100 kWh lithium-ion pack is providing.
Regardless of its increased density, the 150 kWh pack has the identical size, width, and peak of its 100 kWh predecessor (2,062 mm, 1,539 mm and 185.6 mm, respectively), serving to the transition into precise manufacturing automobile proceed extra easily.
NIO’s solid-state battery producer WeLion shared in a July 1 press launch that it had formally begun delivering the 150 kWh packs to the EV automaker on June 30 and confirmed the 2 corporations signed an annual order – though it didn’t disclose its measurement.
Whereas solid-states are being deliberate for at the very least three NIO EVs, it seems these clients who reserved an ES6 (or EL6 within the EU) could possibly reap the benefits of the higher vary first. NIO chairperson and CEO has shared the ES6 will be capable of garner 930 km (577 miles) of vary on a single cost with the 150 kWh pack.
That’s not 1,000 km as promised, however SUVs are much less aerodynamic than sedans, so we’d anticipate one other NIO EV like the ET5, as an illustration, to hit the centennial mark in kilometers. We’ll maintain an eye fixed out to see when the 150 kWh actually turns into selectable to NIO clients and have an interest to see which mannequin(s) will see it delivered first.
