32700 battery

　　The ternary 32700 battery is mainly composed of positive and negative electrodes, a diaphragm and a 32700 battery electrolyte. The lithium-ion battery generates current through the middle of the regenerated diaphragm, and then the battery is charged. As the key cathode materials for ternary lithium batteries, there are two main types: lithium nickel cobalt manganate (NCM) and lithium nickel cobalt aluminate (NCA). Due to the limitations of the current production process, most automobile companies in our country are using ni-co-mno.

　　In the past two years, under the correct guidance of new policies, new energy vehicles have just begun to change their development prospects with high efficiency, relative energy density, and high durability. In order to obtain huge subsidies in our country, many automobile manufacturers have chosen ternary lithium batteries. Replaces lithium-ion rechargeable batteries. According to the survey, the load capacity of ternary lithium batteries this year exceeded the current load of lithium-phosphorus batteries twice, accounting for the proportion of the total load.

　　However, the good times did not last long. Subsidies for new energy vehicles dropped sharply this year, which put great pressure on automobile companies. In turn, due to the impact of the pneumonia epidemic in 2020, people's value in the automobile market has also been greatly reduced. Promoting cost reduction has become the view of the world's automobile companies. the most important. In other words, this is why battery charging companies have been chasing perfection in cobalt-free technology in recent years.

　　Cobalt is a nonferrous metal with very limited reserves worldwide and is relatively expensive. It is understood that there are more than 7 million tons of cobalt ore reserves in the world this year, more than half of which are in Congo, and the long-term instability of local politics has led to huge changes in cobalt imports and exports. In addition, as the popularity of 5G mobile phones increases, the demand for cobalt is also increasing. It is estimated that after 2026, the demand for cobalt will be high, causing the price of cobalt to rise further.

　　In ternary batteries, cobalt mainly has key functions such as maintaining the stability of the basic structure, improving the multiple properties of the circulation system and raw materials, and reducing the resistance of lithium ions.

　　After years of work by raw materials biologists, they have discovered that tungsten trioxide particles are likely to become the preservative of choice for cathode materials in cobalt-free rechargeable batteries. The key is that the relative price of tungsten materials is cost effective and has decreased within 2 years. At the characteristic level, the basic theoretical volume of tungsten oxide powder is 693mah/g, the combustion loss is lower than that of titanium dioxide, and the positive ion transfer rate is much greater than 12cm2/, so as an active material for cobalt-free rechargeable batteries, it can benefit the lithium-ion battery itself physical operation to achieve structural reliability and circulation system characteristics.
