    "body_text": "A Sungkyunkwan University and Seoul National University team reports that its dual-network DHP binder delivered nearly twice the adhesive strength of conventional binders in thick wet-processed electrodes. Commercial-format pouch cells retained 86.8 percent of capacity after more than 200 cycles, while a conventional comparison failed at about 95 cycles. The result narrows a mechanical bottleneck for dense electrodes, but it does not by itself establish electric-vehicle range or mass-manufacturing economics.",
