Naxtra电池：突破性能极限，驱动未来能源
宁德时代Naxtra电池突破了材料本身的性能界限，首次实现了钠离子电池的量产。凭借钠固有的安全性和丰富的储量，有效降低对锂资源的依赖，夯实了新能源技术的基础，推动能源利用从“单一资源依赖”走向“能源自由”。
Naxtra 电池产品线包含两大类：Naxtra 乘用电动汽车电池和 Naxtra 24V 重型卡车集成启停电池。两款产品均能在 -40°C 至 +70°C 的全温度范围内工作，重新定义了电池的极端温度极限。Naxtra 乘用电动汽车电池在 -40°C 时仍可保留 90% 的可用电量。即使在仅剩 10% SOC 的极低电量状态下，Naxtra 乘用电动汽车电池在 -40 ℃ 的温度下仍能保持无明显功率衰减。
宁德时代Naxtra乘用车电池能量密度达到175Wh/kg，为全球钠离子电池中最高，与磷酸铁锂电池相当。其续航里程达500公里，循环次数超过10000次，大幅降低维护成本。在安全性方面，Naxtra电池从材料层面消除了助燃因素，实现了从“被动防御”到“本质安全”的变革性突破。
CATL 的 Naxtra 24V 重型卡车一体化启停电池拥有超过 8 年的使用寿命。与传统铅酸电池相比，它可将总生命周期成本降低 61%。该产品拥有独特的优势，包括全容量深度放电、-40°C 一键启动、闲置一年后即可启动等。与铅酸电池相比，它更高效、环保、经济，推动商用车迈入车辆与电池共生共荣的无铅时代。
宁德时代在钠离子电池性能上的这一重大突破，填补了电池在极寒环境下应用的空白。钠离子电池性能的突破是电池全场景应用的关键进展。由此，宁德时代Freevoy双动力电池应运而生。
Freevoy双电源电池：开启能源自由的多电源时代
Freevoy Dual-Power 是一款深度融合 CATL 双电源架构和自成阳极技术的突破性产品。双电源架构意味着电池组拥有两个强大的“独立能量区”，从而实现双高压、双低压、双结构、双热管理和双热失控安全保护五重双重功能，确保动力输出的连续性、稳定性和安全性。这种双电源设计与软件的创新集成，将为即将到来的 L3 和 L4 自动驾驶时代提供更稳定、更可靠的动力保障。
“自成型阳极技术”代表了原子层面的颠覆性突破，意味着电池体积能量密度可提升60%，质量能量密度可提升50%。这也意味着在相同的电池组空间内可以容纳更多电量，从而支持更长的续航里程。该技术可灵活搭配各种材料体系，与NCM体系结合，能量密度可提升至1000Wh/L以上。
Freevoy双动力电池首创的“双电增程”技术，可根据车辆行驶状态和用户驾驶习惯，直观地调节两个能量区的分配策略。双动力电池的主能量区可根据用户的驾驶习惯和场景采用不同化学体系的电芯，满足日常驾驶需求；增程能量区则可采用高比能量自形成阳极技术，提供更大容量，满足用户的长途出行需求。
现场发布了三种跨不同化工体系的双电源解决方案：
Sodium-LFP Dual-Power Battery – It combines Naxtra with a LFP self-forming anode battery, fully utilizing the low-temperature performance of sodium-ion technology to provide users with an exceptional experience that excels in cold conditions while delivering extended range.
LFP-LFP Dual-Power Battery – It pairs the second-generation Shenxing Superfast Charging Battery with the LFP self-forming anode battery. It easily achieves 1,000 kilometers of pure electric range in sedans with a 3-meter wheelbase, reducing the commuting cost per kilometer to as low as 0.1 yuan.
NCM-LFP/NCM-NCM Dual-Power Battery – It integrates an NCM battery with an LFP self-forming anode battery, achieving a peak charging rate of 12C for the NCM battery in the main energy zone, providing over 1 megawatt of power. Even when SOC drops to 20%, it can still output over 600KW of power. The upgraded version of the product, consisting of an NCM battery and an NCM self-forming anode battery enables a capacity of over 180 kWh in sedans with a 3-meter wheelbase, breaking through the 1,500-kilometer pure electric range barrier.
CATL’s Freevoy Dual-Power EV Battery puts users’ needs at its center, enabling different chemical systems to “collaborate and complement each other” and overcoming the technical bottlenecks that prevent single chemical systems from adapting to all scenarios. This makes customized battery performance possible across different cost segments and application scenarios.
The innovative architecture from dual power to multi power will not be limited to the field of electric passenger vehicles, but will also be implemented in all fields such as electric buses, heavy-duty trucks, airplanes, ships, as well as industrial and commercial applications, accelerating the industrialization of renewable energy across all scenarios. At the same time, it will also accelerate the application process of cutting-edge technologies such as solid-state batteries.
Second-Generation Shenxing Superfast Charging Battery: Setting New Global Records
CATL launched its Shenxing 4C Superfast Charging Battery in 2023, ushering in the era of superfast charging. The release of CATL’s second-generation Shenxing Battery once again pushes the limits of superfast charging performance and sets new world records for charging rates.
CATL’s second-generation Shenxing Superfast Charging Battery is the world’s first LFP battery featuring both an 800 km range and a 12C peak charging rate. With a peak charging power of 1.3 MW, it achieves 2.5 kilometers of range per second of charging, virtually eliminating the frustration of waiting. In low-temperature environments of -10°C, the second-generation Shenxing Superfast Charging Battery can charge from 5% to 80% SOC in just 15 minutes, 100% faster than the industry’s highest current charging level.
此外，宁德时代第二代神星超级快充电池，全温度、全电量状态下，动力强劲。即使在低电量状态下，也能保持830kW的输出功率。在-10℃、低电量的严苛环境下，依然能够轻松满足0-100km/h加速的动力需求。
