Mn Formulated Li-ion Cells For Power Tool and PHEV Applications

摘要

1. Control cell heating (1). Foil ohmic heating, Stack heating, Entropy effect 2. Reduce cell impedance (1). Foil impedance: foil length, foil thickness, tab position (2). Stack impedance: electrode materials and thickness, separator effects (3). Electrolyte conductivity: solvent, salt concentration, additives (4). Reliable, low impedance hardware 3. Rugged Structure (1). Jeilyroll immobilization (26700)- minimize damage from impact and vibration (2). Rigid cap structure Tradeoff: power density vs. energy density.
