Dinho Technology

What Dinho Technology does

Dinho Technology (上海顶皓新材料科技有限公司) is a Shanghai-based, privately held high-tech manufacturer founded in 2013 that develops and produces functional coating materials for new-energy lithium-ion batteries. The company's product portfolio spans two lines: functional coated separators — including heat-resistant ceramic-coated (CCS), polymer-coated (PCS), and multifunctional composite-coated (MCS) separators built on proprietary water-based slurry formulations — and functional current collectors, comprising superconducting, high-adhesive, and composite carbon-coated aluminum foils using carbon black/graphite coatings. These materials target pain points in cell safety (thermal runaway prevention), cycle life (claimed 20–30% extension), internal resistance reduction (~15% on 4680 cells), and fast-charging performance (~25% improvement).

The company operates a vertically integrated B2B model with in-house slurry formulation, coating, and finished-product manufacturing. Revenue is generated through direct hardware sales to battery cell makers serving EVs, energy storage, power tools, and consumer electronics. Reported annual sales average approximately 300 million RMB, with the most recent disclosed year at 230 million RMB. Manufacturing is anchored at the Shanghai headquarters (4 lines, 80 million sqm coating slurry capacity) and the wholly-owned Zhejiang Dinghao subsidiary in Changxing (Phase 1 operational since 2023; Phase 2 completed 2024 with planned 60,000 tons of functional current collectors and 500 million sqm of functional separators annually). New production bases in Sichuan Yibin (broke ground February 2025, 500 million sqm planned) and Anhui (contracted, in planning) extend a planned total capacity exceeding 1 billion sqm of separators per year.

Dinho sells exclusively through a direct B2B sales force with regional offices across seven Chinese cities, supported by participation in major battery industry exhibitions (CIBF2025, The Battery Show Europe) and academic forums. Strategic relationships include Apple (R&D partnership since 2016), BASF, AsahiKASEI (2018 non-woven separator JV), AESC (qualified May 2025), Shenxin New Materials (August 2025 strategic cooperation), and Jiangyin Xiren Aluminum Foil (November 2023 cooperation), alongside university partnerships with Shanghai Jiao Tong University, Beijing University of Science and Technology, and the CAS Qingdao Institute of Energy.

Core offering

Dinho Technology manufactures and sells functional coated separators and functional carbon-coated current collectors for new energy lithium-ion, sodium-ion, and related batteries. The product range includes ceramic-coated separators (CCS), polymer-coated separators (PCS), multifunctional composite-coated separators (MCS), and carbon-coated aluminum foils in composite, superconducting, and high-adhesive variants. These coated materials are supplied as drop-in inputs to battery cell manufacturers serving electric vehicles, energy storage, power tools, and consumer electronics, with custom formulation and coating options offered per customer specification.

Product overview

Dinho Technology is a high-tech enterprise specializing in functional materials for new energy batteries. The company offers two main product lines: functional current collectors (coated carbon aluminum foils) and functional separators (coated separators). The functional current collectors include three types of coated carbon aluminum foils (composite type, superconducting type, and high-adhesive type), while the functional separators include multifunctional coating separators (MCS), heat-resistant ceramic coating separators (CCS), and polymer coating separators (PCS). These products are widely used in electric vehicles, energy storage, power tools, and consumer electronics.

Products and services

• Multifunctional Composite Coating Separator (MCS) A multifunctional battery separator combining ceramic and polymer coatings (PVDF/PMMA) that improves both thermal stability and adhesion between separator and electrode. Designed for lithium-ion battery cell manufacturers serving electric vehicles, energy storage, and consumer electronics.
• Heat-Resistant Inorganic Coating Separator (CCS) Heat-resistant inorganic coating separator using alumina/boehmite coating material, with a self-developed water-based slurry formula delivering high thermal stability, ultra-low moisture, and improved electrolyte absorption. Aimed at lithium-ion battery cell manufacturers that need thermal-runaway-resistant separator input materials.
• Polymer Coating Separator (PCS) Separator coated with polymer PVDF/PMMA via the company's proprietary water-based polymer dispersion and nano-level ionic dispersion technology, available in roll coating and spray coating formats. Improves bonding between separator and electrode for lithium-ion battery cells.
• Composite Coated Carbon Aluminum Foil (PET) Composite carbon-coated aluminum foil using carbon black/graphite coating technology, combining ultra-high safety with excellent adhesion to electrodes. Sold to battery cell manufacturers for use as the cathode current collector in lithium-ion cells.
• Superconducting Carbon-Coated Aluminum Foil High-conductivity carbon-coated aluminum foil manufactured via high-precision, high-speed continuous/gap/complex pattern coating of carbon black/graphite. Enhances current collector surface roughness for stronger active-material adhesion, reduces internal resistance, and improves battery safety and cycle life for cell manufacturers.
• High-Adhesive Carbon-Coated Aluminum Foil Carbon-coated aluminum foil engineered for superior adhesion to electrodes, with excellent organic solvent resistance and corrosion resistance. Provided to lithium-ion battery cell manufacturers as a high-adhesion cathode current collector option.
