On April 21, the "2018 my country New Energy Power Lithium Battery and Energy Storage Industry Conference" was held in Taizhou, Jiangsu. In the sub-forum with the theme of "opportunity, innovation and breakthrough", many power lithium battery experts, scholars and representatives of power lithium battery companies talked about the opportunities and challenges currently faced by the power lithium battery industry at the meeting. Ye Shengji, Deputy Secretary-General of the my country Associatio

Unlike traditional batteries that supply electrical energy in the form of energy storage, hydrogen fuel power cells convert chemical energy into electrical energy through the electrochemical reaction between hydrogen and oxygen. As long as there are sufficient hydrogen and oxygen sources (air sources), this conversion The process can go on forever and achieve zero pollution discharge. It is a new type of power generation technology that is efficient, safe, clean and flexible. At present, hydrogen fuel power cells a

If we say that the dilemma of lead-acid batteries flowing to small workshops is still there, then lithium-ion batteries, which are about to reach the peak of scrapping, will not escape the dilemma, and the situation is even worse. It is understood that electric vehicles may be scrapped after 5 to 7 years of use, and a large amount of scrap is expected to begin in 2018. According to the forecast of my country Automotive Technology Research Center, by 2020, my country's cumulative scrapped power lithium batteries

At present, the two important directions of power lithium battery recycling in my country are cascade utilization and dismantling recycling. When the power lithium battery used in cascade is no longer usable as a battery, its value as a material still exists, so the cascade utilization is down. The battery will eventually be dismantled and recycled. It can be said that how many power lithium batteries are currently produced, and how many waste power lithium batteries will be dismantled in the future. As the termina

The safety of new energy vehicles has always received great attention, and everyone's concerns are also related to batteries, including fire and explosion, leakage, wading, radiation, and so on. In fact, car companies will take these issues into account when developing new energy vehicles, and will deal with them or make concessions in some respects for safety. Here, it is important to understand the cooling system of the power lithium battery. The quality of the cooling performance will directly affect the

Many people know little about lithium-ion batteries, and the difference between fuel-powered lithium-ion batteries and lithium-ion batteries is not very clear. How to decide in the selection process? The following is an analysis of these two power sources. A fuel-powered lithium battery is a power generation device that directly converts the chemical energy and oxidant in the fuel into electrical energy. It involves theories of chemical thermodynamics, electrochemistry, electrocatalysis, material science, power

Lead-acid batteries are generally composed of 3 or 6 single-cell batteries connected in series, consisting of plates, separators, electrolytes, shells, poles and filler plugs (no maintenance-free batteries). Lead-acid batteries 1. Plates of lead-acid batteries The pole plate is divided into positive plate and negative plate, both of which are composed of grid frame and active material. The purpose of the grid. The ladder has a secondary purpose, which will accelerate the precipitation of hydrogen and

Soft case Li-ion batteries are 40% and 20% lighter than steel and aluminum case Li-ion batteries. In terms of weight, soft-loaded lithium-ion batteries are much lighter than hard-loaded lithium-ion batteries, but the important weight ratio still depends on the weight of the box. different abilities Soft-pack lithium-ion batteries are 10% to 15% higher than steel and aluminum batteries, and 5% to 10% higher than steel and aluminum batteries. Although the capacity of soft-pack lithium-ion batteries is not much

As a core component of digital products and electric vehicles. Lithium-ion batteries in these products typically consist of multiple cells. During use, charge and discharge performance and battery life may be significantly reduced due to increased internal core temperature of the battery cells. Especially for power lithium batteries in the automotive field, accurate cell temperature estimation and monitoring are critical to the performance and life of the entire battery system.(Lithium - Ion Battery Equipment)
