Recently, the Yiwei lithium-energy square aluminum shell ternary battery project and the cylindrical lithium-manganese battery project production line were officially put into operation in Jingmen, Hubei, with an annual production capacity of 15GWh and 150 million respectively.

First take the battery down, solder the cable, and wipe it clean with a rag The next step is to open the cover.

This summer's most "fire" is no more than new energy vehicles I believe that everyone has seen a lot of reports.

Tube automakers are working on the next generation of electric cars, but a British company, Riversimple, has its own unique idea Riversimple has developed a hydrogen-powered car that promises to be a viable alternative to electric vehicles.

The active material on the positive electrode of the lead-acid battery is lead dioxide, the active material on the plate is spongy pure lead, the electrolyte is a certain concentration of sulfuric acid solution, and the electromotive force between the plates is about 2V The active material on the positive electrode plate of the nickel-cadmium battery is nickel oxide powder, and the active material on the negative electrode plate is cadmium oxide powder.

Cathode material in NiMH battery: Nickel-based current collector: foamed nickel or nickel foil; Active material: nickel hydroxide nickel (Ni) 2; Conductive agent: nickel powder; Additives: cobalt, cobalt oxide, Y2O3, Yb2O3, etc; Adhesive: CMC, PTFE, etc.

The compaction density of the surface coating material has a very important relationship with the electrochemical performance of the battery Reasonable compaction density can effectively increase the electrochemical performance of the battery, reduce the contact resistance and AC impedance of the electrode, and increase the participation in the electrochemical reaction.

Lithium batteries are the first choice for electric vehicle battery upgrades After the lithium battery is widely applied to portable communication tools such as mobile phones, its green quality has been recognized.

UL specification for carrying lithium batteries: thrown into the fire, the explosion of the battery requires that the explosion radius be no more than 1m Of course, the greater the capacity of the mAh, the greater the explosive power is, the difference between a firecracker and a hanging firecracker.
