As we all know, the batteries on smartphones aren't working so well, they 'll almost last a day But it's our fault, too, because we 've been charging in the wrong way.

In recent years, the new energy vehicle officially ushered in the outbreak period, the power battery industry chain is gradually transformed from policy-driven to market-driven From the perspective of the market demand for power batteries, the number of devices installed in 2018 May no longer boom but tend to grow steadily.

This is often seen in our forum, because the number of charge and discharge is limited, so the power of the cell phone battery should be recharged as much as possible But I found an experimental table on the charge and discharge cycle of lithium-ion batteries.

Baili Technology announced on the evening of April 17 that the company and Ningxiahanyao signed the "Contract for Intelligent Production Line Design and Construction of Lithium-ion Battery Graphene Three-ary Positive Material and Conductive Pulp Project" with a contract amount of 1295 billion yuan.

The German carmaker Daimler has decided to end its worldwide production of energy storage products for home batteries and disbanded its us unitMercedes-benz spokeswoman MadeleineHerdlitschka told reporters the company's battery is "over-engineered" for use in home storage.

Recently, the draft of the "Specifications and Dimensions of Power Battery for Electric Vehicles", which was revised by the National Automobile Standardization Technical Committee, was released publicly The draft of the power battery is divided into three categories: cylindrical, square and soft.

"The more lithium batteries are discharged, the greater the battery loss," said Tom Hartley, an electrical engineering professor who helped NASA study extended battery life "The more charged the battery, the greater the battery loss.

Unexpectedly, the battery became the most photogenic word of the year for mobile phonesOn December 2, Apple released "information about the iPhone and accidental shutdown" on its official website(including the Chinese website), explaining the reason why iPhone 6s users have repeatedly reported that the iPhone has half or even 80 % of the power of the iPhone.

With the large-scale promotion and application of new energy vehicles in China, problems such as short range of electric vehicles and long charging time have emerged Users are eager to achieve breakthroughs and improvements in energy density, charging time, service life, and safety technologies for new energy car power batteries.

Sichuan Luqiao announced on the evening of May 9 that the company intends to jointly set up a project company to build a "10,000 ton/year lithium three-yuan positive material and 20,000 tons/year positive material precursor project" with a construction period of about 2 years It is expected to be put into production in 2020.
