Battery Test Manual for Baselining and Benchmarking Pre-commercial Cells

Due to the wide array of battery form factors, chemistries and real-world applications, a uniform cell performance test methodology is needed to assess the unique capabilities of each cell-type and fit those capabilities to a suitable real-world application. Additionally, new prototype cells need to be effectively and fairly benchmarked against current commercial cell-types which necessitates standard practices during cell testing. This manual is intended to provide a battery testing methodology which can clearly and unbiasedly identify cell strengths and weaknesses across various cell types and chemistries. This manual should be employed to test rechargeable battery chemistries (Li-ion, Na-ion, etc.). Unless otherwise denoted, each test is to be run with 5 cell replicates to improve statistical reliability and build in redundancy to minimize gaps in data collection due to human error, instrument malfunction, etc.
