Does sodium battery will be the best marine battery in 2025?
In the past 2024, the commercialization of sodium-ion batteries has made significant progress. Some leading companies in the industry are actively developing a new generation of sodium-ion batteries, focusing on improving the performance of sodium-ion batteries and reducing their costs in order to prepare for the upcoming large-scale commercial production.
Why is there so much interest in sodium batteries? There are several possible reasons.
1. Raw materials of the sodium-ion battery is widely distributed and easy to obtain. The content of sodium in the earth's crust accounts for 2.3%, ranking sixth among all elements. In comparison, the content of lithium accounts for only 0.0017%. People have enough reason to believe that the large-scale production of sodium-ion batteries will no longer be limited by the supply bottleneck of raw materials.
2. Some materials to produce lithium batteries are mainly distributed in conflict mineral areas. With the surge in global demand for lithium batteries, the mining and supply of these materials have become a focus of attention. However, sodium-ion batteries do not require any of them.
3. Lithium battery cost is affected by major materials like lithium, cobalt. Consumers have deeply experienced the series of troubles caused by the price fluctuations of lithium batteries in the past few years. But the material price of sodium-ion batteries will become very stable due to the influence of sufficient supply.
4. The performance improvements of lithium batteries are becoming very hard today. The continuous lithium battery safety accidents have cast a shadow on consumer confidence. Sodium batteries have shown some unique advantages in performance compared to lithium batteries, and manufacturers believe that with the continuous improvement of materials and production processes, sodium batteries will be safer and more reliable than lithium batteries.
Lead acid batteries are dominated the marine starting batteries, even if they are short life cycle and environmental pollution. Sodium batteries have excellent pulse power performance at low temperature, and this benefit overcomes the disadvantages of lithium batteries. Sodium batteries are the much better choice in the field of marine starting, thanks to their excellent life cycle, charge and discharge efficiency comparing with lead acid batteries.
Are sodium batteries safer?
There is no rechargeable battery is absolutely safe. Compared with lithium batteries, sodium batteries are a little better on thermal stability, but extreme high temperature environments can still cause thermal runaway of sodium batteries. Sodium batteries also need a battery management system (BMS) to protect them from overcharging and overheating. The BMS can make sure that sodium batteries always work within allowed conditions, thereby avoiding the occurrence of thermal runaway.
What sodium batteries can be used for marine starting?
DEFORD New Power Co., Ltd. released four marine sodium-ion batteries in Q4, 2024. The excellent performance of these batteries can meet the technical requirements of most marine starting batteries. These batteries are all equipped with intelligent BMS, which can fully protect the cells to work within the allowed conditions and avoid any thermal runaway accidents.
With the NaPALION App, end users can monitor, control, or OTA upgrade the battery through Bluetooth communication. The built-in Emergency Start function can prevent the battery from being over-discharged, thus providing a reliable starting capability for marine.
