12V sodium battery for EV systems promises 5,000+ cycles, 10x lifespan

UNIGRID has introduced its Na⁺ Fleet platform, a 12V starter battery system based on sodium-ion NaCrO₂ (NCO) cells, targeting the global $50 billion battery replacement market dominated by lead-acid batteries. Unlike traditional lead-acid batteries, which are heavy, require frequent maintenance, and typically need replacement multiple times during a vehicle’s life, the Na⁺ Fleet cells offer significant advantages including a lifespan exceeding 5,000 cycles—about 10 times longer than lead-acid counterparts—and the ability to be stored indefinitely at 0% state of charge without capacity loss or maintenance charging. The Na⁺ Fleet batteries operate within a voltage range of 8 to 14.4V, compatible with existing vehicle alternators and do not require an active Battery Management System due to passive balancing. They deliver more than twice the cold cranking amps of lead-acid batteries across a wide temperature range (–40°C to 60°C), addressing performance issues under
