Development of Wide Temperature Range Electrolytes for Start-Stop Vehicle Applications - (PPT)

摘要

6000 batteries were made and tested within a year, nearly 40% reduction on both HT impedance growth and LT impedance achieved! New solvents and additives are both required for wide temperature range performance: 1. Bulk electrolyte properties play a bigger role at low temperature for LTO; 2. SEI properties are important to both graphite and LTO.
