LTC Takes UUV to New Depths

Lithium Technology Corp. of Plymouth Meeting, Pennsylvania, has developed, in conjunction with Phoenix International Inc., a high performance pressure-tolerant battery for unmanned underwater vehicle (UUV) applications. UUVs are increasingly used to perform underwater work faster and more efficiently while removing the need for a manned presence from an inherently dangerous environment. LTCês pressure-tolerant lithium-ion cells are integrated into Phoenix-designed battery packages and can withstand ocean pressures greater than 10,000psi, an equivalent water depth of four miles. The U.S. Navy funded the battery project for use in military UUVs, which have also been applied to other applications, including oil exploration, water tunnel inspection and cinematography. In a collaborated effort, each LTC cell is equipped with integrated electronics, which are married to a battery management system developed by Phoenix International. Additionally, each cell is replaceable, making the battery serviceable and cost effective while providing a superior solution to other available products.
