Anacortes, Wash., headquartered Lavle USA Inc. reports that it is developing the world’s first, large scale, Solid Electrolyte Battery (SEB) Energy Storage System (ESS) for the marine market.
The Lavle marine solution will utilize SEB cells supplied from its Japanese joint venture partner, 3DOM and application engineering expertise from its American joint venture partner, Ockerman Automation.
The 3DOM SEB cells utilize a unique, patented separator technology that enables the use of lithium metal in the anode and solid materials for the electrolyte between the cathode and anode electrodes
Lavle holds the exclusive rights to the 3DOM SEB technology for application in the marine, defense, oil & gas, and renewables markets.
Lavle says that, compared to existing ESS technologies, its SEB ESS solution offers:
- Greatly increased energy density
- Much higher degree of safety due to unique separator
- Allows for a very high depth of discharge
- Faster charge rates
- Enables the use of non-flammable electrolytes
- Greatly extended life cycle
- Much lower volume and weight – novel integration schemes possible
- Low losses within a wide ambient temperature range
Lavle plans to release the commercial version of the SEB ESS within 12 months. The team is utilizing the company’s Marine Electric Propulsion Simulation (MEPS) Laboratory located in Newport News, Va., to prototype, test and characterize the performance of the ESS.
The company has engaged DNV-GL to start initial evaluation of the cells and application.
Currently, SEB cells are being supplied from the 3DOM plant in Japan and then packaged in Anacortes. Lavle and 3DOM are in the process of selecting a larger manufacturing site in order to satisfy the company’s long-term vision to produce and package the separator and SEB cells in the U.S.A.
