Nio Day was a hit not solely due to the presentation of the ET7, an EV that can have a range of up to 1,000 kilometers (621 miles). Its future swappable battery pack with 150 kWh and solid-state batteries additionally obtained individuals very . The primary experiences had been that CATL would provide these batteries. Nonetheless, the Chinese language media is now pointing to a different firm: Strong State Lion. If you happen to by no means heard about it, you aren’t alone.

The knowledge got here from Moneyball, a Twitter person that experiences on fascinating information from China associated to electrical vehicles in a really correct method. Verify their tweet beneath.


We tried to examine the data with Strong State Lion straight. Sadly, the corporate’s web site appears to be outdated and the one e-mail handle out there there now not works. All we needed to take care of was the web site. Fortunately, it has an English model.

Strong State Lion’s pages on the internet affirm that it’s related to the Institute of Physics on the Chinese language Academy of Science. In response to the company’s founding background information, the Institute of Physics determined to grant Strong State Lion “core mental property rights of solid-state batteries” in 2017, one 12 months after the corporate was created. Its full title is Beijing WeLion New Vitality Expertise. Its founder, professor Chen Liquan, investigates lithium-ion conductors since 1977.

Presently, Strong State Lion claims to have 17 patents on solid-state batteries. They would come with the event of stable electrolyte supplies – a vital a part of the solid-state know-how – “composite lithium steel destructive electrode,” “excessive vitality density constructive and destructive supplies” (most likely that means cathodes and anodes), and a excessive vitality density solid-state battery pattern.


When you think about that QuantumScape has greater than 80 granted patents on the know-how and greater than 100 pending patent functions associated to solid-state batteries, the 17 Strong State Lion would have will not be a formidable quantity. The purpose must be which patents every of those firms have. A dependable and straightforward to provide stable electrolyte could be a game-changer and probably require just a few patents concerned with it.

One other level that wants additional data is manufacturing capability. If Nio is to purchase these batteries from Strong State Lion, manufacturing output must be sufficient for the carmaker’s calls for. The Chinese language solid-state cell firm says it has “greater than two manufacturing bases,” however we do not know what that basically means.

If these experiences about Strong State Lion are appropriate, maybe we could have one other sturdy competitor to produce these batteries sooner or later aside from QuantuScape and Solid Power. Why we by no means heard about it might be credited to how onerous it’s to get in contact with Chinese language firms and the way little information different nations get about what occurs there. If we’re to take solely what the web site informs us, Nio’s provider should be one other one.

We’ll attempt to examine with Nio with few hopes that it will likely be capable of inform us something at this level. If different firms uncover the place Nio intends to get its solid-state batteries from, they could attempt to get them earlier with extra engaging affords. Maybe Strong State Lion’s web site is outdated and too discreet for an enormous firm on objective…
