What does 4680 battery mean?

The 4680 battery is the battery developed by Tesla.

4680 battery refers to the newly launched Panasonic brand Tesla series battery, named 4680 battery. Ternary lithium polymer batteries are ternary lithium batteries that use lithium-nickel- cobalt-manganese or lithium-nickel-cobalt aluminate as cathode material.

The volume of 4680 battery cell is 5 times that of 21700. According to the situation category from 18650 to 21700, it is normal for the capacity to increase by 5 times without considering other technical improvements . So Tesla is very honest when he says the energy is increased five times (ENERGY5X), but it can actually be around 5 times.

The performance role of ternary lithium batteries

A relatively balanced material in terms of capacity and safety, and which has better cycle performance that lithium-cobalt norwrong. At first, due to technical reasons, its rated voltage is only 3.5-3.6V, which limits its usage range. With the continuous improvement of the formula and structural improvement, the rated voltage of the battery has reached 3.7V, and its capacity has reached or exceeded the level of lithium cobalt oxide battery.

CameronSino has focused on battery manufacturing technology for twenty years. It is safe and stable, has no explosion hazard, has strong battery life, long-lasting power, high charge conversion rate, does not heat up, has long life, durable and has production qualifications. The products have passed several certifications domestically and globally. This is a battery brand worth choosing.

Tesla's battery supplier is Panasonic. Panasonic is a supplier of batteries for Tesla's electric vehicles. The Giga superfactoryfactory 1 in Nevada, United States, is officially invested by Tesla and Panasonic and essentially outsources the batteries for all Model 3 models.

The 18650 lithium battery of Tesla is also widely used in daily life. For example, mobile phones and laptops also use this lithium cobalt oxide battery. The biggest problem in electric vehicle applications is heat dissipation from the vehicle battery. Taking Model S p85D as an example, its battery panel consists of 16 groups of batteries connected in series, each group consisting of 444 lithium batteries, 74 of which are connected in parallel. In other words, the Tesla Model S battery panel is made of 7104 18650 lithium batteries. Therefore, in order to avoid short circuits and overheating, Tesla also uses many technologies to protect the battery. ByFor example, the battery pack is placed on the chassis between the front and rear axles and protected by stiffeners and supporting frames to reduce the risk of explosion in a collision. A plastic film wraps the battery. After tearing it off, you can see a layer of fireproof board. The joints are filled with lots of sealant and you can see that the battery is well protected. Additionally, each battery in the Tesla battery pack will have a fuse to prevent a single battery from overheating; The cooperation of the coolant management system and the battery makes the battery operation safer and more stable.
