Dry-Process Electrode Manufacturing (4)
Dry electrode processing removes the solvent, drying oven and solvent-recovery stages of conventional wet coating. Its principal engineering obstacle isdispersion uniformity: without a liquid medium, active material, conductive agent and PTFE binder are difficult to mix evenly, and any non-uniformity propagates into areal density variation, localised resistance and reduced cycle life. These four patents cover the route end to end.

Battery Materials & Process Environmental Control (14)
Manganese sulphate purification for cathode precursors, plus the fluorine and dust control processes that sit alongside it. Fluorine handling is intrinsic to lithium battery chemistry — LiPF₆ electrolyte hydrolyses to HF, and cathode sintering releases fluorine-bearing gas — so defluorination and precursor purification belong to the same production chain.

A note on patent titles and terminology
The English titles shown on Google Patents and in the CNIPA public database aremachine-generated from the Chinese originalsand are not reviewed technical translations. Several render Chinese terms literally in ways that carry a different meaning in English engineering usage. The titles listed on this page therefore use standard industry English. Each patent number links to its official record, where the original machine-translated title can be verified.
| pole piece | electrode / electrode sheet—pole piecenormally denotes a magnetic pole piece in motors |
| charging structure | material feeding structure—chargingin a battery context means electrical charging |
| separator/sorter | cell sorting machine—separatorin a battery context means the porous membrane between electrodes |
| membrane | dry electrode film— a self-supporting active-material film, not a separator |
| roll squeezer | roller press / calender |
| high multiplying factor | high-rate (C-rate) |
| ferric phosphate lithium | lithium iron phosphate (LFP) |
| nickel-cobalt lithium manganate | lithium nickel cobalt manganese oxide (NCM) |
Example: CN215656472U appears on Google Patents as "Battery separator with prevent stifled device". The Chinese specification describes acell sorting machinethat measures internal resistance and grades cells — it has no relation to separator membranes.

In His Words
"Battery equipment is not a catalogue purchase. The right machine depends on your cell design, your target output and the process window you can actually hold in production. That conversation has to start with engineering, not with a price list."
Frequently Asked Questions
What are Dany Huang’s main research directions?
Two active research lines, both with published output. First,sodium-ion cathode materials— specifically O3-type layered oxides and multi-element co-doping to prevent crystal structure collapse during repeated sodium insertion and extraction. Second,lithium-ion battery safety— overcharge-induced thermal runaway thresholds and heat-resistance design. In parallel, his patent work concentrates ondry-process (solvent-free) electrode manufacturingand battery production equipment, which is where the research feeds back into machine design.
What did the B-Co-Cu co-doping study find?
Published inJOM(Springer / TMS, 4 June 2026) with Dany Huang as first author, the study applies a solid-solution B-Co-Cu ternary co-doping strategy to Na[Ni1/3Fe1/3Mn1/3]O2. The optimal composition NNMFO-B0.07-Co0.05-Cu0.03 reached an initial discharge capacity of129.4 mAh g−1at 0.2C(4.6% above undoped) and99.0 mAh g−1at 5C(24.8% above undoped), with93.60% capacity retention after 100 cyclesand 78.49% after 300 cycles at 1C. Na+diffusion rose 9.48% and the O3–P3 phase transition shifted from an abrupt two-phase reaction to continuous solid-solution-like behaviour, suppressing intergranular microcracks.
At what temperature does overcharge cause thermal runaway in lithium-ion cells?
His 2023 sole-author study inSci-Tech Innovation & Productivityfound no overcharge-induced thermal runaway below 160 °C and runaway above 165 °C, establishing160–165 °Cas the critical range and 160 °C as the design threshold. State of charge governs onset: insulation thermal-runaway temperature falls from 181.1 °C at 0% SOC to110.2 °C at 100% SOC, while anode heat generation rises from 110.2 to 469.4 J/g across the same range. Peak recorded temperature was 568 °C at 17.6 °C/min.
What is Dany Huang’s dry electrode patent portfolio?
A four-patent chain covering the complete dry-process route stage by stage: raw-material feeding and mixing uniformity (CN219193253U), self-supporting film roll forming (CN218887233U), lamination and stretching (CN218887274U), and full film-forming plus substrate-lamination production line integration (CN118315678A). The first three are co-held with co-founder Tobey Chen; the line-integration patent is held individually.
How many patents does Dany Huang hold, and what do they cover?
55 Chinese patents as of September 2026 — 5 granted invention patents, 45 utility models and 5 published applications — with more applications in progress. By subject: battery production equipment (16), battery materials and process environmental control (14), broader industrial process engineering (13), dry-process electrode manufacturing (4), cell design and cathode materials (4), and process plant and auxiliary equipment (4). Every patent number on this page links to its official record on Google Patents.
What are his granted invention patents about?
Vijf patenten die de inhoudelijke toets van CNIPA hebben doorstaan, een aanzienlijk hogere lat dan voor gebruiksmodellen. Drie daarvan zijn celontwerpen uit de beginfase van zijn carrière: een zeer veilige, krachtige LFP-batterij (CN101436654B), een krachtige NCM-lithium-ioncel (CN101425605B) en een drukregelbare veiligheidsontluchter (CN101399324B). Twee betreffen procesmilieubeheersing: een bereidingsmethode voor defluorering van actief koolstofmateriaal (CN108793160B) en een systeem voor de zuivering en terugwinning van fluorhoudend gas (CN108355479B).
Hoe sluit zijn technische achtergrond aan op de apparatuur van TOB?
Hij werkt sinds 2002 in de lithium-ionbatterijtechnologie en heeft zich beziggehouden met pouch-celmaterialen (2002-2006), cilindrische cellen (2007-2008) en grote prismatische cellen met een aluminium behuizing (2009-2010) voordat hij in 2012 TOB NEW ENERGY oprichtte. De 16 patenten voor batterijproductieapparatuur die het bedrijf bezit, omvatten de volledige elektrodelijn – van mengen en toevoeren tot coaten, kalanderen, snijden, wikkelen, sealen en sorteren – waardoor het machineontwerp gebaseerd is op directe ervaring met de productie van cellen en niet alleen op de levering van apparatuur.
