Battery Diagnostics & Instrumentation Intern

Coreshell Technologies•San Leandro, CA

3h•$26 - $40•Onsite

About The Position

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: We are seeking a motivated intern to support ongoing work in experimental diagnostics and analytical instrumentation. The role focuses on hands-on laboratory activities and contributes to the adaptation, improvement, and validation of custom experimental measurement systems used in electrochemical R&D. This position is well suited for candidates who are comfortable working close to hardware, enjoy understanding measurement systems at a system level, and are interested in turning complex experimental outputs into quantitatively meaningful data.

Requirements

Strong interest in hands-on experimental research and instrumentation.
Familiarity with electrochemical characterization techniques and lithium-ion battery fabrication.
Demonstrated ability to modify or adapt hardware/experimental setups.
Familiarity with volume-based or gas-handling experimental systems (e.g., EC-MS) is a plus.
Experience translating physical system behavior into quantitative data using Python, MATLAB, or similar tools.
Ability to process experimental data and identify baseline drifts or artifacts.
Familiarity with chemistry lab safety protocols and commitment to organized work areas.
Currently pursuing or recently completed a degree in Mechanical Engineering, Chemical Engineering, or a closely related field.

Responsibilities

Assist with the setup, operation, modification, and adaptation of experimental and analytical equipment
Contribute to improving and validating custom measurement setups to meet evolving experimental requirements.
Collaborate closely with engineers and scientists on experimental problem-solving and system-level improvements.
Perform Coreshell’s in-house battery fabrication and testing.
Participate in data acquisition, processing, and detailed experimental recordkeeping.
Identify and correct sources of measurement error, drift, or system artifacts.
Perform cell failure analysis through post-test cell disassembly followed by physical, compositional, and electrochemical characterization.
Manage inventory of chemicals and lab consumables and maintain standard operating procedures (SOPs).
Execute manual tasks requiring high precision and dexterity.
