Recently, Samsung smart phone Galaxy Note 7 due to the explosion of lithium battery recall caused widespread consumer concern Small cell phones will explode, often carrying hundreds of kilograms of power lithium battery electric vehicles are still safe? There's no future for electric cars without safety.

Lithium batteries contain harmful substances such as lithium hexafluorophosphate, which can cause serious pollution to the environment and the ecosystem Heavy metals such as cobalt, manganese, and copper can also be harmful to humans through the accumulation of biological chains.

There are few problems with the battery itself of the brand phone, and problems with the battery itself appear in the converter or second phone In order to save costs, mobile phones or re-furbishers tend to choose lower-cost low-quality batteries in mobile phone configurations.

"Yes, we are doing this(looking for a new battery partner) and it seems that at least one new partner is needed" On April 24, Haiziman, president and CEO of Volkswagen Group(China), confirmed to the Economic Watch Network that Volkswagen is looking for a second battery partner in China.

The rechargeable battery life generally refers to the cycle life of the rechargeable battery According to national regulations, when the battery capacity is reduced to 70 % of rated capacity under the conditions of full charge and discharge, the number of cycles that the battery can achieve is the cycle life.

Chengfei said that the decline in performance was mainly due to the adjustment of the new energy vehicle subsidy policy, the combination of production line transformation, the reaffirmation of supporting models, and the fact that new production capacity has not yet been released The revenue of the lithium battery business fell 33.

A major breakthrough in the field of electrolytic chemistry, published in the latest edition of the journal Science, is that American scientists have used liquefied gas for the first time to replace electrolytes, allowing lithium batteries and super-capacitors to operate efficiently at minus 60 °C and minus 80 °C, respectively The new technology not only improves the mileage of single-charge electric vehicles in the cold winter, but also provides electricity for drones,specials, and interstellar detectors in extremely cold environments.

As of the end of April this year, the city has built a total of about 127,000 charging piles, of which about 20,000 public charging piles have been built in public parking lots such as large shopping malls, transportation hubs, and highway service areas, forming a six-ring area The average service radius of 5 kilometers of public charging network.

If the battery appearance is not damaged, bulging, there is no short circuit, and there is no sign of breaking the road, the following methods can be used to try to repair the battery: 1, the use of positive and negative pulses to depolarize the battery, and then completely discharge, so that the cycle three times, if the capacity has recovery signs, can be more than a few cycles to achieve better repair results 2, add water repair, add water must be added ion water or pure water, do not add tap water, will cause the battery self-discharge problem.

The Chinese lithium battery industry is catching up at an alarming rate: in less than three years, the country could be home to a giant lithium battery maker that surpasses Tesla's super battery plant According to Bloomberg new energy finance, a think-tank, if the country's leading battery makers can meet their scheduled production targets, China's lithium battery capacity will reach 121 gigawatt-hours (GW) a year by 2020.
