Sodium-ion batteries have arrived.
High Energy Density: The battery design aims for high efficiency and possesses a high energy density, which means it can provide longer range on the same volume or weight.
Excellent Cycle Life: The battery can maintain over 80% of its capacity after more than 2000 cycles under standard conditions (e.g., 0.5C/0.5C charge-discharge), indicating its durability and long-term stable use in applications such as electric vehicles.
Wide Operating Temperature Range: The battery can operate normally within a temperature range of -40°C to 65°C and exhibits good capacity retention in both low and high temperature environments. It can maintain at least 90% of its capacity even under extreme -30°C conditions and reach 100% at 55°C, demonstrating its strong adaptability to environmental changes.
Outstanding Rate Performance: It excels in fast charging and high-current discharging, maintaining a high level of capacity utilization even at 5C or 10C charge rates. Similarly, in discharge rate tests, it can maintain a high level of capacity retention even under 5C and 10C high-current discharging conditions.
Safety Protection Mechanisms: The battery features a full-pole design to enhance current-carrying capacity and heat dissipation. The combination cap integrates CID (Current Interrupt Device) and Vent, providing two levels of safety protection to ensure the battery’s safety in the event of thermal runaway, meeting the regulatory requirements for escape time (meets automotive power battery requirements).
High-Temperature Storage Stability: After storing at 55±2°C for 7 days, the battery exhibits a very high level of charge retention and capacity recovery, demonstrating its excellent storage performance under high-temperature conditions.
