An all-solid-state battery works without a liquid electrolyte, but in exchange it must be “pressed” so its solid particles stay in contact, and this pressing is needed twice.
This piece maps Forge Nano’s 2024-granted patent US12027661B2 — which could potentially cover ALD nanocoating broadly for high-nickel (80%+ nickel) cathode material — against its 2015 foundational patent US9196901B2 in a claim chart, and identifies design-around points.
An analysis of the claim scope and design-around possibilities in Solid Power’s frame patent (US20260088331A1), which prevents edge damage when all-solid-state pouch cells are pressed in an isostatic press.
Based on the claims and example data in SK On’s dry-electrode calendering patent (US12199265B2), granted in 2025, this article analyzes the narrow claim scope defined by a compression ratio of 0.10 to 0.65 and the possibility of a competitor’s design-around.
The core reason lithium-sulfur (Li-S) batteries have long failed to cross the commercialization threshold is the “polysulfide shuttle,” and the patent literature has developed along several routes that “suppress” this problem rather than eliminate it.
Placing City Labs’ US12094620B2 side by side with BetaVolt’s CN119207858A, this article analyzes the difference in claim scope between the direct semiconductor-conversion approach and the converter-plus-supercapacitor approach.
Comparing CATL’s cathode coating patent (WO2026045268A1) with Rivian’s anode interface layer patent (US12424625B2), this article examines FTO and design-around points for all-solid-state battery interface technology.
The remaining battery percentage on an EV dashboard is not a directly measured value but an estimate that the battery management system (BMS) computes from voltage, current, and temperature data using algorithms.
This article directly compares and analyzes CATL’s (CN121964524A) and BYD’s (CN121768970A) all-solid-state battery interface degradation prevention patents, based on the original text on Google Patents.
This article analyzes CATL’s international cathode-coating patent WO2026045270A1 claim by claim — covering its scope of claims, positioning relative to prior art, points to check for FTO, and design-around scenarios.
