Many users who use laptops will have a question, "Does the laptop need to be plugged in all the time?". This article focuses on this question and talks about my own views.

China's leading battery companies have recently notified contracted customers to renegotiate prices, and their quotations may increase by about 20%. It is understood that the domestic battery industry will basically raise prices in a unified manner in the near future. The long-term contract signing method is still under negotiation with downstream companies next year. It can also be seen that the willingness of battery companies to increase prices this time is firm.

There are many reasons for choosing electric vehicles, but I believe that friends who choose fuel vehicles have two very important reasons: one is that fuel vehicles will not have the problem of mileage anxiety; the other is that the time cost of waiting for refueling is very low.

Cylindrical lithium batteries usually refer to cylindrical 18560 lithium batteries, which can be divided into three material systems: lithium cobalt oxide, lithium manganate, and ternary materials. Batteries are widely used in: notebook computers, digital cameras, lighting fixtures, toy products, power tools, portable mobile energy and other fields.

Everyone is familiar with ternary batteries, and its cathode material is usually nickel-cobalt-manganese or nickel-cobalt-aluminum. What kind of battery is a quaternary battery that is one yuan more expensive than a ternary battery?

Recently, the China Automobile Manufacturers Association's November data release conference was held in Beijing. The China Automotive Power Battery Industry Innovation Alliance released monthly power battery data for October 2021. The total power battery output was 25.1GWh, an increase of 191.6% year-on-year.

Cylindrical lithium batteries are divided into different systems such as lithium iron phosphate, lithium cobalt oxide, lithium manganate, cobalt-manganese hybrid, and ternary materials. The outer shell is divided into two types: steel shell and polymer. Different material systems have different advantages.

With the rapid release of demand for new energy vehicles, the power battery, which is the heart of new energy vehicles, is encountering a new round of imbalance between supply and demand.
