[Patent Analysis] Screening Out Defective Cells From the First Charging Curve — The Boundary of the Formation-Data Method Claimed in CATL US12540983B2

/

CATL’s US12540983B2 claims a method that feeds the values at which dQ/dV, dynamic internal resistance or dV/dQ first reach two process variations in the first formation stage into a two-dimensional Gaussian model to screen out cells with electrolyte or moisture anomalies. We set out the claims and family, and why switching to Mahalanobis distance leaves the boundary unchanged.

[Patent Analysis] When an Augmentation Decision Becomes a Claim — The Boundary of ESS Capacity Management in Fluence US12632024B2

/

Fluence’s US12632024B2 claims, as one closed loop, estimating ESS capacity from field data and taking a corrective action that adjusts temperature, configuration, number of components or material according to the result. We follow its rainflow partial-cycle dependent claim and three forms of independent claim to read the boundary of the rights and the room to design around them.

[Patent Analysis] The Sun That Warms Also Locks the Heat Path — The Claim Boundary of Lockheed Martin’s Satellite Battery Thermal Management Patent (US7967256B2)

/

US7967256B2 (Lockheed Martin Corp, priority 2007-05-08, granted 2011-06-28) places a variable-conductance heat pipe’s reservoir next to the radiator so sunlight closes the heat path on its own. We break down all 7 claims by element to map the design-around points and the patent’s expiration strategy.

[Patent Analysis] Filling Electrolyte ‘Atmospheric-Pressure First,’ Not ‘Vacuum First’ — The Claim Boundary of the Reduced-Pressure Cycle Drawn by US10476097B2

/

Envision AESC Energy Devices’ electrolyte-injection patent US10476097B2 (priority 2015-04-16, granted 2019-11-12) claims not vacuum itself, but a sequence that begins at atmospheric pressure and then alternates between injection and reduced pressure. Using a claim chart against the prior reference US6530145B1, this piece identifies the design-around points and the counterarguments to them.

A Quieter Patent Than the 4680 — How Panasonic Used Graphite Particle Strength to Control Resistance Variation in Cylindrical Cells

/

Panasonic’s US patent US12080916B2 claims that when negative-electrode graphite particles simultaneously meet two property windows, ‘internal porosity of 5% or less’ and ‘breaking strength of 25-55 MPa’, the cell-to-cell variation in internal resistance shrinks in cylindrical cells whose negative electrode directly contacts the outer can.
