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?
中国国家知識産権局(CNIPA)の実体審査を通過した特許は5件で、実用新案よりも審査基準がかなり高い。そのうち3件は、キャリア初期段階のセルレベルの設計に関するもので、高安全性・高出力のLFP電池(CN101436654B)、高出力のNCMリチウムイオン電池(CN101425605B)、圧力調整可能な安全弁(CN101399324B)である。残りの2件はプロセス環境制御に関するもので、脱フッ素化活性炭材料の製造方法(CN108793160B)とフッ素含有ガスの精製・回収システム(CN108355479B)である。
彼の工学系の経歴は、TOBの機器とどのように関連しているのでしょうか?
彼は2002年からリチウムイオン電池のエンジニアリングに携わり、パウチ型電池材料(2002~2006年)、円筒型電池(2007~2008年)、大型角型アルミニウムシェル電池(2009~2010年)を経て、2012年にTOB NEW ENERGYを設立しました。同社が保有する16件の電池製造装置特許は、電極の混合・供給からコーティング、カレンダー加工、スリット加工、巻取り、封止、選別までの全工程を網羅しており、装置設計は単なる装置供給ではなく、電池製造における直接的な経験に基づいています。
