Comparison of advantages and disadvantages between lithium-ion batteries and sodium ion batteries. China's batteries are mainly used in three major industries, namely electric vehicles, energy storage, and consumer electronics. Around these three directions, especially in recent years, the electric vehicle and energy storage fields have developed rapidly, with a focus on lithium-ion batteries. Compared to lithium, sodium is widely present in nature and relatively easy to obtain. However, early sodium ion battery prototypes had the characteristics of low performance and short lifespan. Now, sodium ion batteries have become a new promising direction for implementation. This article analyzes the advantages and disadvantages of lithium-ion batteries and sodium ion batteries.

Working principle and advantages of sodium ion batteries

Principle: During the charging and discharging process, Na+is inserted and removed back and forth between the two electrodes. During charging, Na+is removed from the positive electrode and inserted into the negative electrode through the electrolyte; When discharging, the opposite is true.

Advantages:

(1) Sodium salt raw materials have abundant reserves and low prices. Compared with ternary cathode materials for lithium-ion batteries, using iron manganese nickel based cathode materials reduces raw material costs by half;

(2) Due to the characteristics of sodium salts, low concentration electrolytes (with the same concentration electrolyte, sodium salt conductivity is about 20% higher than lithium electrolyte) are allowed to reduce costs;

(3) Sodium ions do not form alloys with aluminum, and aluminum foil can be used as the current collector for the negative electrode, which can further reduce costs by about 8% and weight by about 10%;

(4) Due to the non over discharge characteristics of sodium ion batteries, they are allowed to discharge to zero volts. Sodium ion batteries have an energy density greater than 100Wh/kg, which is comparable to lithium iron phosphate batteries. However, their cost advantage is significant and they are expected to replace traditional lead-acid batteries in large-scale energy storage.

Comparison of advantages and disadvantages between lithium-ion batteries and sodium ion batteries

1. The difference in the internal charge carriers of batteries is that lithium batteries charge and discharge through the movement and conversion of lithium ions between the positive and negative electrodes, while sodium ion batteries charge transfer through the insertion and extraction of sodium ions between the positive and negative electrodes. In fact, the working principles of the two are the same.

2. The two have different ionic radii, which results in the performance of sodium ion batteries being far inferior to that of lithium-ion batteries; The negative electrode of lithium ions can make graphite, but sodium ions can hardly be removed/embedded in graphite, resulting in a small capacity; Other carbon materials can reach a maximum of about 300 milliampere hours after treatment; The capacity of ions in the positive electrode is very small, only over 100 milliampere hours; The insertion/deintercalation resistance of sodium ions in the positive and negative electrodes is high, due to the large radius; Poor reversibility and significant irreversible capacity loss.

Current situation of China's sodium ion battery industry

Sodium ion batteries are an emerging industry that may require more research and development to bloom the rose of time. The industrialization of sodium batteries is accelerating in China at present. In January 2019, Liaoning Xingkong Sodium Battery Co., Ltd., located in Anshan, recently entered the mass production stage of independently developed sodium ion batteries. The world's first sodium ion battery production line was put into operation, and it is expected that the annual output value will exceed 10 billion yuan after large-scale production.

From the perspective of industry situation, the industrialization of sodium batteries is still in its early stage, and many research results are only circulated in universities and research institutes. It will take some time before they truly land - even some researchers have stated that sodium ion batteries have no chance until the lithium reserves on Earth are depleted. Sodium batteries may also be like artificial intelligence technology, which may not be initially favored and can only be circulated within academic circles. However, one day, there may be a sudden change and they will quickly land in the industry. This is very likely, so sodium batteries are actually worth the high attention of forward thinking entrepreneurs and investors.

Sodium ion batteries are one of the important development directions for future energy storage batteries. With the continuous progress of sodium ion research and development technology, the commercialization process of sodium ion batteries will continue to accelerate, and perhaps early deployment in this field is expected to seize the opportunity in the field of new energy batteries. Of course, it seems too early to say that sodium ion batteries are replacing lithium batteries.
