Coreshell's metallurgical Silicon anode technology delivers high capacity, fast-charging, and superior safety. Our low-cost liquid-phase nano-coating addresses critical electrode-surface degradation issues and enables batteries with a Silicon-dominant anode that have higher energy density, superior intrinsic thermal safety, and significantly lower cost/kWh compared to current LIBs. Our Si anode material is lower than the cost of graphite and 100% domestically sourced. We strive to transform the global automotive market by enabling low-cost and long-range EVs as a first step towards net-zero sustainability in the near future.

Core Responsibilities::

1.Process Development & Failure Mode Mitigation

• Lead Formation process development for 60Ah pouch cells, translating lab-scale insights into manufacturable recipes
• Conduct Process FMEA to identify potential failure modes in the formation workflow—spanning electrolyte wetting, temperature control, current response, degassing, and cell sealing.
• Quantify process risk severity, occurrence, and detection to prioritize control actions and process improvements.
• Apply Fault Tree Analysis (FTA) to trace system-level cell performance issues (e.g., plating, voltage hysteresis drift, impedance rise) to specific process, material, or equipment causes.
• Lead cross-functional root-cause investigations integrating electrochemical, mechanical, and process data.

2. Testing & Cell Qualification

• Develop and execute statistically robust DOE plans to study the effects of formation variables on cell lifetime and degradation.
• Define qualification metrics including first-cycle efficiency, voltage-shift behavior, impedance evolution, and plating onset thresholds.
• Automate test data pipelines to extract diagnostic fingerprints for qualification and failure prediction.

3. Degradation Mechanism Studies

• Identify and model key degradation pathways (Li plating, SEI/CEI growth, transition-metal dissolution, gas evolution, etc.) as a function of formation and cycling history.
• Perform electrochemical characterizations and post-mortem correlation to quantify reaction- and diffusion-limited losses.
• Establish predictive links between formation signatures and field lifetime performance using statistical reliability models
• Support design-of-experiments to isolate electrochemical vs. mechanical degradation contributions under thermal, C-rate, and voltage stress tests.

Requirements:

• B.S. degree or equivalent in Chemistry, Chemical Engineering, Materials Science OR an experience in a similarly relevant field with 2+ years of industrial experience.
• Previous experience in battery cell development, process development, or manufacturing environment preferred
• Able to safely work in a manufacturing setting.
• Strong verbal and written communication skills
• Self-starter with an ability to operate on his/her own initiative
• Creative problem solver and able to juggle multiple projects at any given time
