Solid State Battery Lithium Titanate Battery -Lithium - Ion Battery Equipment

Solid State Batteries and Rechargeable Lithium Titanate Batteries -Lithium - Ion Battery Equipment

After the lithium titanate battery was supported by Gree Electric, another news came from the power lithium battery market: solid-state batteries are also being sought after.

Recently, British billionaire James Dyson (James Dyson) said that he will invest 1.4 billion US dollars to build a battery factory, which will be a big gamble for him and the company named after him.

In 2015, Dyson acquired solid-state battery company Sakti3, when Dyson said it would invest nearly $1 billion to mass-produce solid-state batteries. Therefore, the outside world believes that the above-mentioned factories will be responsible for mass production of solid-state batteries.(Lithium - Ion Battery Equipment)

Musk looks down on solid-state batteries, Wang Chuanfu has denied lithium titanate batteries

Compared with lithium-ion batteries commonly used in electric vehicles, solid-state batteries have no electrolyte inside, but are replaced by a "sandwich" device, which can not only act as an electrolyte to ensure the normal transmission of ions, but also prevent the contact between the positive and negative electrodes. response to reduce battery explosion accidents.

The electrolyte of lithium-ion batteries is an organic liquid, which is prone to oxidative decomposition and combustion reactions at high temperatures. Solid-state batteries do not have this problem, so they can ensure battery safety.

It stands to reason that the above advantages should make solid-state batteries highly sought after by the industry. However, solid-state batteries are still facing development bottlenecks that the production process needs to be improved and the cost needs to be reduced, so they have not become the mainstream product of power lithium batteries.

TSLA CEO Elon Musk (Elon Musk) once said that he is not optimistic about the prospects of solid-state batteries. He believes that it is difficult to reduce the production cost of solid-state batteries to the current level of production costs of lithium-ion batteries.

Coincidentally, Wang Chuanfu, chairman of BYD, also expressed a negative attitude towards lithium titanate batteries. Wang Chuanfu believes that lithium titanate batteries may be marketed in local areas, especially at extremely low temperatures, but they still need to "work hard".

Musk and Wang Chuanfu have more possibilities for "selfish" power lithium batteries

It should be pointed out that Musk and Wang Chuanfu are staunch "supporters" of ternary lithium-ion batteries and lithium iron phosphate batteries, respectively. Therefore, solid-state batteries and lithium titanate batteries are viewed as declining, although there are reasons for their own lack of technology, But it is also related to the positions of Musk and Wang Chuanfu.

Two "hard corners" in the power lithium battery market debut: solid-state batteries and lithium titanate batteries

At present, the power lithium battery market is dominated by ternary lithium-ion batteries and lithium iron phosphate batteries, but these two batteries also have development bottlenecks. For example, ternary lithium-ion batteries have the advantage of high battery life. TSLA electric vehicles are equipped with ternary lithium-ion batteries, and the cruising range can reach more than 500 kilometers. However, ternary lithium-ion batteries are less stable and require extremely high battery management. System technology, otherwise it is easy to spontaneously ignite or even explode under violent collision.

The advantage of lithium iron phosphate battery is stability, but its disadvantage is low energy density and poor battery life. The energy density of lithium iron phosphate battery is 100-120WH/KG, while the energy density of NCA (nickel-cobalt-aluminum) and NCM (nickel-cobalt-manganese) ternary material batteries is 50% higher than that of lithium iron phosphate, currently generally at 150 -180Wh/kg, TSLA's NCA ternary material battery energy density has reportedly reached 200Wh/kg.

The incompatibility of battery life and battery safety is the embarrassing status quo of the current development of power lithium batteries. For the sake of "discourse power", the company has "selfishness" beyond reproach, but the development of the power lithium battery industry must let go of "selfishness" and embrace more possibilities.

Lithium titanate batteries have the advantages of long life, safety, fast charging, and wide temperature resistance, but their energy density is close to that of lithium iron phosphate batteries.
