Frequently Asked Questions

What kind of yield problems does Pinery Gong work on?

Assembly-section defects that sit between process and equipment: electrolyte leakage, internal short circuit, electrode fracture, tab defects, separator misalignment, internal resistance and dimensional deviation. The working method is root-cause analysis with closed-loop correction across winding, stacking, electrolyte filling, sealing and formation — typically taking a defect mode from percentage-level down to parts per million rather than trimming it by a few points.

How was electrolyte leakage reduced from 6% to 60 ppm?

Through a dedicated improvement programme on a core failure mode at Wanxiang Technology (Microvast Electronics), 2020–2022, leading a 15-person process team. The same programme took electrode fracture from10% to 80 ppmand overall cell pass rate from75% to 90%. Performed at that employer and presented as career history, not as a performance guarantee for a new project.

How was PACK output raised from 500 to 15,000 units per shift?

A thirty-fold increase achieved through full automation rollout combined with process iteration, at Wanxiang Technology (Microvast Electronics). In the same period PACK pass rate moved from85% to 99%and total labour cost fell20%through operation merging, process optimisation and headcount rationalisation. Career history at that employer.

What experience does he have with prismatic aluminium-shell cells?

As process department head at Geely Technology Lixin Energy (2022–2024) he held full process technical management for prismatic aluminium-shell power and storage cells. NCM-manganese cell short-circuit rate fell from10% to 0.5%through workshop humidity control, bend structure redesign and equipment upgrade; separator misalignment fell from6% to 0.2%. He led the DX45AH, NCM40, Geely G2 and 50AH storage programmes from B/C sample through to SOP, lifting project pass rates from 70–88% to93–95%. Career history at that employer.

Has he commissioned new production lines?

Yes. At CITIC Lixin Energy (2017–2020) he took full part in acceptance, commissioning and production ramp of a4 GWh Korean-imported automated line, roughly doubling line capacity, and built the first complete set of assembly-section process documentation from nothing — parameter standards, PFMEA, SOPs and control plans. Core process pass rates reached99% or aboveafter winding, assembly and filling optimisation. His new-line work covers equipment requirement definition, technical agreement review, FAT/SAT acceptance and jig validation. Career history at that employer.

Can he build a process organisation, not just fix defects?

Yes. At Geely Technology Lixin Energy he rebuilt the Zhenjiang site process organisation from scratch, growing the team from10 to 40 engineersand establishing role definitions, assessment mechanisms and workflows to meet automotive OEM audit standards. At Envision AESC he built a unified assembly process library across global manufacturing sites, delivering assembly BOM, process specifications, PFMEA and control plans. Career history at those employers.

Which cell formats has he worked across?

Four: 3C pouch cells (TCL Jinneng and Zhongshan Tianmao, where tab defects fell from20% to 500 ppmy se introdujeron más de cien nuevos modelos en la producción en masa), celdas de acero y de consumo (Wanxiang, que suministra productos a clientes como OPPO y Amazon), celdas de energía y almacenamiento con carcasa de aluminio prismática (Geely Lixin, CITIC Lixin) y ensamblaje de bolsas prismáticas plus en Envision AESC.
