The issue of safety can be summarized as thermal runaway of power lithium batteries, which means that when the battery is heated to a certain temperature, it becomes uncontrollable. The temperature rises linearly, exceeding 500 ℃ or 1000 ℃, and then it will burn and explode. Why is there thi...

1、 Basic Introduction 1、 Squeeze coating type Regarding extrusion coating, I understand it as applying fluid through a coating head with a special flow channel to a moving substrate. According to the distance between the coating head a...

The technological bottleneck in the development of electric vehicles lies in battery performance, so what is the bottleneck of power lithium batteries? Why do power lithium batteries need to be divided into soft and hard packaging? What is its practical significance? Below is an explanation fr...

The electrolyte solution in the primary battery is made into a gel and does not flow, also known as a dry battery. Ordinary zinc manganese and alkaline zinc manganese batteries are all dry batteries. Secondary batteries, also known as rechargeable batteries or batteries, can be recharged after...

Working principle of lithium-ion batteries Before introducing the shape of the battery, let's first briefly understand the working principle of lithium-ion batteries. Lithium ion batteries are a type of secondary battery (rechargeable battery) that relies heavily on the...

Recently, a seminar on the Guangdong local standard "Technical Requirements for Lithium Ion Batteries and Battery Packs for Unmanned Aerial Vehicles" for lithium-ion batteries used in unmanned aerial vehicles was held at the Guangdong Institute of Product Quality Supervision and Insp...

The current demand in the new energy market continues to be sluggish, with large high-temperature alloy and magnetic material manufacturers having sufficient electrolytic cobalt raw materials, and the spot market transaction scale is relatively small. SMM believes that there is little chance o...

Some small cobalt acid lithium battery manufacturers are concerned about the price increase of upstream cobalt raw materials, and have recently increased their inquiries for cobalt acid lithium. The upstream quotation for cobalt tetroxide in lithium cobalt oxide has increased, while the quotat...

The prices of cobalt salt and nickel salt were relatively stable this week, and the demand in the power market was still weak. The orders in June were not as expected. The 523 single crystal and 811 precursor were slightly adjusted with the price of cobalt salt, and the overall market price wa...

The operating rate of the power battery factory in July has basically increased compared to June, with an average month on month increase of 15%. A certain head battery factory's production schedule has increased by 30% -40% month on month, mainly due to the recovery of overseas high nicke...
