Partially-submerged battery cells for vehicle energy-storage systems
First Claim
1. A energy-storage system comprising:
- a coolant section having a coolant circulated therein;
a non-coolant section having a fluid other than the coolant disposed therein;
a plurality of battery cells having a coated portion and a non-coated portion, the coated portion being disposed in the coolant section, and the non-coated portion being disposed in the non-coolant section; and
a retainer disposed between the coolant section and the non-coolant section, the retainer holding the plurality of battery cells, the retainer forming a seal around the plurality of battery cells, the seal preventing the flow of coolant from the coolant section to the non-coolant section,wherein the coated portion is coated with a coating material having a high electrical resistance and a high thermal conductivity; and
wherein the coating material comprises at least one of aluminum oxide, diamond powder based materials, and boron nitride.
