Mine-Neutralization Vehicle Thermal Battery
Agency / Branch:
DOD / NAVY
Thermal batteries are a mission critical component used in virtually every modern day weapons system. The mine neutralization vehicle requires a high energy density (> 70Wh/kg), multi-hour life (minimum 1hr.) power source that operates at relatively low power (100-120 watts). It has been shown, using ENSER's electrochemical and thermal modeling programs, that these requirements can substantially be met with a Li(Si) /LMP/CoS2 thermal battery of the appropriate voltage by combining two parallel cell stacks (each containing seven cells) to maintain a low current density and incorporating them into a single battery case. The major concern about the proposed design is whether battery will operate for the desired time of up to 3 hours before failing due to electrolyte leakage and cell-to-cell shorting when pre-conditioned at 75¿C. Designing and incorporating peripheral cell edge seals to minimize the egress of electrolyte from the cells and thus prevent premature shorting of the battery will address this potential problem condition.
