What is GOLD CARBON Co., Ltd. and what products does it make?
GOLD CARBON CO., LTD. is a Taiwan-based company founded in October 2017 whose specialist team works on the commercialisation and volume production of batteries, quantum dot materials and graphene. Its scope covers lithium batteries, battery packs and carbon materials. Products include Safety Battery lithium cells, High-Density cells at 280–340 Wh/kg, High-Rate 10C/20C cells, and R2R ALD surface-modification technology.
Where is GOLD CARBON based, when was it founded, and who leads the company?
GOLD CARBON is based at 1F., No. 247, Puzhong Rd., Zhongli Dist., Taoyuan City, Taiwan. It was founded in October 2017 and its chairman is Liu Wen-Nien. The company works on batteries, quantum dot materials and graphene, and holds ISO 9001:2015 certification. Its telephone number is +886-3-427-6066.
What makes GOLD CARBON's Safety Battery different from a conventional lithium pouch cell?
GOLD CARBON's Safety Battery is a lithium cell designed not to ignite or explode under physical damage, overcharge, over-discharge or short circuit. In its nail penetration test (3 mm nail at 50 mm/sec) it showed no fire and no explosion, where a conventional lithium cell would go into thermal runaway. After being sawn through, it held about 4.0 V for the full 2 minutes 45 seconds measured. It also uses aluminium-laminate pouch construction.
What did GOLD CARBON do in the Minus eBike project beyond supplying cells?
Beyond supplying cells, GOLD CARBON handled the e-bike three-electric system integration for the Minus eBike, integrating battery, motor and controller. The work spanned cell selection, pack design, protection circuitry and vehicle-level matching. The project used High-Density Series cells at 280–340 Wh/kg, with multi-layer protection against explosion, overcharge and over-discharge.
Working with us
What information should I send a battery manufacturer so they can assess whether my cell requirement is feasible?
Send the manufacturer your required capacity, dimensions and application, plus the discharge rate if it is a high-power use. GOLD CARBON's product pages ask for these, and for space constraints on long-runtime cells, so it can assess feasibility. For custom manufacturing, it also asks for your specification and quantity.
How can I contact the purchasing department of GOLD CARBON in Taoyuan?

Battery basics
Lithium battery that does not catch fire when punctured
GOLD CARBON's Safety Battery is a lithium cell designed not to ignite or explode under physical damage, overcharge, over-discharge or short circuit. In its nail penetration test, a 3mm nail driven through the cell at 50mm/sec produced no fire and no explosion. After being sawn through, the cell's voltage held steady at around 4.0 V for the full 2 minutes 45 seconds measured.
What does C-rate mean on a lithium battery, and what is the difference between a 10C and a 20C cell?
C-rate is the unit of discharge speed, showing how quickly a cell can be fully discharged: 1C delivers full capacity in one hour, 10C in six minutes and 20C in three minutes. The higher the number, the greater the current the cell can deliver instantaneously, so a 20C cell can supply more instantaneous current than a 10C cell.
How is a lithium pouch cell made, step by step, from slurry mixing to grading?
A lithium pouch cell is made in five stages: preparation (slurry mixing, coating, calendering); stacking (die cutting, electrode stacking); assembly (top and side sealing, baking); electrolyte filling (filling, pre-formation); and finishing (formation, degassing and sealing, grading). GOLD CARBON breaks these five stages down into nine production stations running in sequence.
What does atomic layer deposition do to a lithium battery cathode, and why does it improve cycle life?
Atomic layer deposition (ALD) coats a cathode surface with a nanometre-thin oxide film, grown one atomic layer at a time. The film suppresses side reactions between electrode and electrolyte, which are one root cause of capacity fade, heat generation and thermal runaway. Fewer of these reactions is why GOLD CARBON's R2R ALD modification gives longer cycle life with reduced capacity fade. Film thickness, 0.2–10 nm, is set by the number of ALD cycles.
What is a cross-section cut test on a lithium cell, and why is it considered harsher than a nail penetration test?
A cross-section cut test saws a lithium cell clean through, then checks whether it still works. It is harsher than nail penetration because penetration punches a single hole while the cut does far greater damage. GOLD CARBON reports its Safety Battery held steady at around 4.0 V for an unedited 2 minutes 45 seconds after being cut, with no voltage collapse from an internal short.
