ZKJ POWER’s 12V sodium-ion batteries overcome the low-temperature drawbacks of lead-acid and ordinary lithium batteries. Offering steady discharge down to -20°C, they serve reliable off-grid power for RV travel, outdoor glamping, cold-chain logistics, marine yachts and remote frigid off-grid areas, winning new global orders across cold climate markets.

Sodium-ion batteries possess prominent advantages in cost performance and low-temperature adaptability, and are poised to become an effective complementary technology to lithium-ion batteries. The working mechanism of sodium-ion batteries is analogous to that of lithium-ion batteries; the charge carrier shifts from lithium ions to sodium ions, with corresponding optimizations made to cathode materials, anode materials, electrolytes and current collectors.

The cathode adopts layered oxides, polyanionic compounds and other material systems, while hard carbon serves as the mainstream anode material. Although sodium-ion batteries feature relatively lower energy density, they demonstrate remarkable cost advantages upon large-scale industrialization. Additionally, they deliver outstanding low-temperature performance, superior rate capability and high safety, continuing the development logic of lithium iron phosphate batteries and serving as an important supplement to lithium-ion batteries.
 ZJLK has officially launched its 12V series sodium-ion batteries this year, including 12V30Ah, 12V50Ah, 12V70Ah and 12V100Ah models.

With the launch of sodium batteries by Tianan and Super V, CATL has also made it clear that it will start mass production of sodium batteries in 2026. These batteries are not affected by cold in winter and have a long service life. Many users want to replace lead-acid batteries with sodium batteries to enhance the performance of their electric vehicles.

It should be noted that replacing lead-acid batteries with sodium batteries is not as simple as just swapping lead-acid batteries. Besides the battery itself, other components also need to be replaced, especially these four parts which must be changed. Let's take a look together.

Ten major difficulties and problems faced by industrial and commercial energy storage urgently need to be solved. 
Top Ten Development Trends of Industrial and Commercial Energy Storage

On June 1, 2025, Zhejiang Zhongkejie Energy Technology Co., Ltd. (hereinafter referred to as "zkjpower") officially launched its newly developed "Integrated Solar-Storage-Diesel Power Solution for Industrial and Commercial Use." This solution aims to provide stable, efficient, and low-carbon power to energy-intensive enterprises and industrial parks worldwide. This solution combines intelligent coordinated control of photovoltaic power generation, energy storage systems, and diesel generator sets to significantly reduce corporate electricity costs while improving energy supply reliability.
