4.Single cell structural features
Interaction structure of the independent single cell convection heat more effectively to avoid overheating;Independent positioning fulcrum structure of single cells can effectively prevent the battery string dynamic vibration environment, Destruction of the battery outer layer of insulation isolation to avoid moving the friction of the string, to avoid cumulative squeezing effect, eliminating the mutual squeeze caused by the internal battery by extrusion damage to the battery separator dangerous; Pressure constant pressure structure to keep the battery stable pressure, the better to avoid bonding at the sealed insulated isolation at the affected by water infiltrating into.Lithium titanate lithium ion battery single cell
