Why develop sodium-ion batteries?
Sodium ion battery sodium distribution ratio of 2.74%, and the price of raw materials is very stable. Sodium battery cost compared to lithium iron phosphate batteries may be 30-40% less, good low temperature performance, low temperature ion battery rate is higher, higher conductivity. Sodium ion batteries have better wafer ion diffusion ability, high safety performance, the moment a short circuit occurs is not easy to produce danger.
August 25, 2021 China’s Ministry of Industry and Information Technology (MIIT) to carry out the development of sodium-ion battery standards, and support in the standardization of the project, standards for approval and other aspects. Now to carry out the standardization of sodium-ion batteries and the development of more than 10 work in progress.
Suggestions on the exemption of consumption tax on sodium-ion batteries, to further reduce the industrialization of sodium-ion batteries and the cost of sales, and to promote the scale of sodium-ion planning.
There are also exemptions from the purchase tax, on the basis of the existing with the sodium-ion electric vehicles to promote the electric vehicle for passenger electric vehicles system electric system mass energy density of not less than 95wh/kw proposed exemption from the purchase tax.
The advantages of lithium battery and sodium battery development basically carried out at the same time, 1991 sony company took the lead in commercialization, but the capacity of sodium ions in graphite is only one tenth of the Li electron, no value.
In 2017, Chinese scientists found a new type of positive electrode only, gram capacity close to 500mAh, commercialization feasibility. in December 2018, nanjing university of science and technology, in cooperation with Chinese and foreign teams, the first combination of the design of the sodium ion battery.
Sodium-ion battery materials side of the advantage is significant, the forward battery cost gathered 0.5 per wh, sodium-ion battery anode using sodium carbonate 3000 RMB per ton compared to lithium carbonate 500,000 per ton price significant advantage. The immaturity of the sodium-ion battery equipment process, the industrial chain is partially perfect, we expect about 0.8-0.9 per wh.
However, sodium-ion battery pain points also have, is in the energy density, power density than lithium-ion batteries poor, the main reason is that in carrying the same charge, sodium ions than lithium ions to be two times larger.
However, sodium-ion batteries have excellent safety performance, CATL R & D team through the design of a reasonable battery structure and strict process, can ensure that sodium-ion batteries in the use of the process of safety performance, sodium-ion batteries high temperature overcharging over the side of the stability is better, greatly enhancing the safety of the battery.
After pinprick, impact, drop, short circuit and other tests do not explode, the development trend of lithium-ion batteries and sodium-ion electric batteries for two wheeler electric bike, 2019 year interest in the global epidemic, electric bicycles due to the low price, flexible and convenient convenience attention.
China’s electric bicycle industry also ushered in the explosive growth is expected to 2023 the year of China’s two-wheeled vehicle total output reached more than 48 million, China’s prospect is relatively good.
Sodium-ion batteries as a replacement product for batteries, make policy arrangements for sodium-ion batteries, sodium-ion batteries mass production began to accelerate, it will become the first year of mass production of sodium batteries in 2023, and low-speed electric vehicles become the first marketable application scenario.
Sodium power industry discourse is a new high ground in the global competition, energy storage has an advantage in the field of sodium power anode materials are mainstream, the development of sodium power is the country’s strategy, with the maturity of sodium batteries is expected to replace the market of lithium iron phosphate battery.
According to the planning of many countries for sodium-ion batteries, sodium-ion battery-related products are gradually starting to form commercial applications, and the market situation for sodium-ion batteries is expected to grow significantly in the near future.
Trend 1: 2023 will be the first year of sodium batteries.
Trend 2: Sodium battery shipments will exceed 1Twh in 2030.
Trend 3: sodium power industry discourse will be the new global energy technology to fight for the high ground.
Trend 4: Sodium power will continue to be a hot spot for investment in primary and secondary markets in the next 10 years.
Mass production of sodium batteries
2023 is the first year of sodium-ion batteries, in terms of range, sodium-ion batteries have been close to lithium iron phosphate, far beyond lead acid motorcycle battery. Sodium ion energy density has been close to 140Wh/kg, thanks to the prevalence of raw materials, it is expected that the price of sodium ion batteries will be about 70% of lithium iron phosphate after mass production. In addition to cost and range advantages, sodium-ion batteries have the following advantages:
Good safety performance: safer, can pass the puncture test, no fire.
Good low temperature performance: it can still work normally at -40°C, suitable for colder cities in the north.
Fast charging: high efficiency of energy conversion, can finish charging within 1~3H.
Large capacity, large multiplier: with a larger capacity than ordinary batteries, high efficiency output, scale discharge 2~5C, sustained high current discharge up to 10C.
Battery over-discharge: Battery over-discharge even to 0V, the battery is not leaking or damaged.
Environmentally friendly and non-polluting: Sodium ion batteries do not contain any heavy metals and rare metals, non-toxic and non-polluting, in line with the European RoHS regulations, for the absolute green battery certificate.
In summary, after the mass production of sodium-ion batteries, its excellent low-cost, high safety, medium range, long life performance, will be in the field of two-wheeled electric vehicle batteries, eating a lot of lithium iron phosphate, lead-acid batteries in the market, will gradually form a lead-acid exit, lithium and sodium competition.
