China’s new national standard counts a cell as solid-state only if under 0.5% of its contents escape under heat and vacuum. I read the first production cell to pass it alongside the maker’s own patents.
Battery news articles and spec sheets pile up numbers such as V, Ah, Wh, Wh/kg, C-rate, SOC/SOH and cycle life.
Lithium sulfide accounts for 80-90% of a sulfide solid electrolyte BOM. A reading of the Q3 2026 hundred-tonne pilot commissioning through cost structure and the process claims of US11183708B2.
The real battleground for solid-state batteries is the electrolyte. This piece compares the sulfide, oxide, and polymer pathways and lays out why Samsung SDI is focusing on sulfide.
LG Energy Solution’s international application WO2026038783A1 seeks to solve the problem of manganese-rich LMR cathode material fracturing during electrode rolling by mixing two types of LMR particles of different sizes with one type of single-particle NCM particle.
This article organizes the China-led launch of the international all-solid-state battery standard in August 2026, along with the mass-production roadmaps of CATL, Toyota-Idemitsu, and Samsung SDI — including key patents and points to watch for design-arounds.
This article analyzes, from a patent portfolio perspective, ‘SolidStack,’ the pouch-type all-solid-state battery for Physical AI that Samsung SDI unveiled at InterBattery 2026.
Pre-lithiation compensates for the silicon anode’s initial capacity loss. The foundational SLMP patent is set to expire in November 2026, but process-condition patents remain in force until 2038.
The move to replace graphite anodes is not converging on a single substitute; it is proceeding along two tracks, lithium metal at the premium end and hard carbon at the entry-level end.
What the dry electrode process sells is process cost; what it pays for it is freedom in material choice. This piece lays out how the constraint of PTFE fibrillation narrows the composition patent landscape.
