In recent years, the market demand for large batteries has been increasing. The promotion of this includes the pure electric vehicles that are expected to become popular in the future, and the large-sized rechargeable batteries used in stationary power storage systems that have received much attention since the Great East Japan Earthquake on March 11, 2011. Previous research and development protagonists have been rechargeable batteries for portable terminals. However, since the battery capacity...

Recently, BYD’s secretary-general Li Wei revealed that BYD will expand its ternary lithium battery layout in the future. In 2016, BYD expects battery capacity of 10GW·H, and in 2017, it will add ternary battery of 5-6GW·H. BYD is the world's second largest and largest domestic power battery manufacturer. It has always adhered to the technical route of lithium iron phosphate battery and is the leader in the global lithium iron phosphate battery technology. BYD has also begun to lay out...

The possible reasons why the battery and battery pack cannot be discharged are: 1 The battery is stored and used, its life is attenuated; 2 insufficient or not charged; 3 The ambient temperature is too low; 4 The discharge efficiency is low. For example, when the large current is discharged, the ordinary battery cannot keep up with the reaction speed due to the diffusion rate of the internal material, so that the voltage drops sharply and the electricity cannot be discharged.

Possible reasons for the battery and battery pack not charging: 1 battery zero voltage or zero voltage battery in the battery pack; 2 The battery pack is connected incorrectly, and the internal electronic components and protection circuit are abnormal. 3 charging device failure, no output current; 4 External factors cause the charging efficiency to be too low (such as extremely low or very high temperatures).

Today, more than 90% of solar batteries are still dominated by colloidal batteries. Why? The main reason is cost.   However, there is a commonly used street lamp called integrated street lamp, which uses lithium iron phosphate battery, which is small But there are still problems: Due to the small capacity of the battery, the LED street lights can only be equipped with low power, but the power is small, so the lumens are small, and the lighting effect of such street lights will be relatively...
