Is BYD's all-solid-state lithium battery expensive?

Introduction Is the cost of BYD's all-solid-state lithium battery high? BYD's all-solid-state lithium battery costs between $120 and $200/kWh, which is enough to power smartphones if they are made using existing technology.

Is BYD's all-solid-state lithium battery expensive?

High. The cost of BYD's all-solid-state lithium battery is 120-200 US dollars/KWh. If existing technology is used to make a solid-state battery sufficient to power smartphones, the cost will be close to US$10,000. relatively high, and the cost of R&D and manufacturing equipment needs to be amortized, the development of solid-state batteries is difficult, and the development investment cost is high.

Cost of lithium batteries for mobile phones

First, in terms of battery prices, lithium batteries are more expensive than lead-acid batteries.

For example, a set of lead-acid batteries on the market now costs between four and five hundred yuan, while lithium batteries of the same energy generally cost more than a thousand yuan. a lithium iron phosphate battery is even more expensive. Therefore,In terms of price, lithium batteries generally cost twice or more than lead-acid batteries.

Second, in terms of battery capacity, lithium batteries of the same size have more capacity.

Because the average voltage of lithium batteries is higher than that of lead-acid batteries, that is, the energy density is high, so for batteries of the same volume , lithium batteries have greater capacity.

Regarding the same lithium battery, the capacity of the ternary lithium battery is greater than that of the lithium iron phosphate battery, and the capacity of the lithium iron phosphate battery is greater than that of the lithium manganate battery.

Third, in terms of battery weight, lithium batteries of the same volume are lighter than lead-acid batteries.

This means that the energy density of the batterieslithium is larger. For example, the energy of one kilogram of lithium batteries is equivalent to the energy of three to five kilograms of lead-acid batteries. therefore the same energy. Then, lead-acid batteries are heavier.

So if we want to be more convenient and lighter to twist, we can choose lithium batteries.

Fourth, in terms of battery safety, lead-acid batteries are safer.

The main component of lead-acid batteries is water, there is no organic electrolyte and explosions or fires are rare.

However, lithium batteries have a certain sealed space and contain organic materials if used improperly, explosions and fires may occur.

Fifth, in terms of battery life, lithium batteries are about three times longer than lead-acid batteries.

The standard for thisJudgment is that for the same quality, the number of cycles of lithium batteries is about 1,000 times, and that of lead-acid batteries is about 300 times. if you use lead acid battery, you need to recharge it after 300 times charging, the battery will basically enter the aging stage, so the lifespan of lithium batteries will be longer.

15 yuan. Lithium batteries for mobile phones are mainly composed of plastic upper and lower covers, lithium batteries, protective circuit boards (PCBs) and resettable fuses (polyswitches). The cost price of the battery in 2022 will be 15 yuan and the sales price will be 50 yuan. Lithium batteries for mobile phones are popular among consumers due to their long life and faster and safer charging.
