2/ Battery experts have been working for decades to solve solid-state, as solid electrolytes are game-changing for batteries’ energy density and safety. QS, after 10 years of R&D, now claims to be 4-5 years away from commercially viable solid-state batteries.

4/ Solid-state separators were previously not possible without compromising cell performance (life cycle, temperature range, charging rate, energy density) or driving up costs. Through its testing results, $QS has demonstrated its unprecedented solution to all of these issues.

6/ QS cells can be charged to 80% SoC in 15 minutes, significantly faster than current lithium-ion batteries, which charge to less than 50% in 15 minutes. QS has said its separator may eventually allow for EVs to be fully charged in less than 5 minutes.

8/ Unlike liquid electrolytes, the QS solid-state separator is noncombustible and has high thermal stability. It operates across the entire automotive temperature range, with test results showing operation at -30°C.

10/ QuantumScape is backed by @BillGates , Tesla co-founder and former CTO JB Straubel, and @VW , to name a few. VW has also agreed to a manufacturing JV, and plans to have QS technology in its EVs by 2024/25.

11/ QuantumScape management seems to be realistic and honest about the timeline for its technology and financials–very refreshing in this space. The stock $QS is up 127% since its IPO two weeks ago.
