At present, lead battery is widely used in the field of energy storage and power, but the traditional lead battery negative plate the sulfuric acid salinization phenomenon, lead to shorten the life, has not been able to get a satisfactory application in the field of energy storageAMD group battery development department senior engineer, said rick wong in the field of energy storage load, etc, the part of the charged state operation of the battery, the battery is in a state of loss of electricity, prone to sulfuric acid salinization phenomenon, the negative plate to generate larger particles sulfate crystals, which hinder the battery of the electrochemical reaction, reduce the cycle life of the battery.
Points from the categories, there are two categories of electric car batteries, batteries and fuel cellsBattery is suitable for pure electric vehicles, including lead-acid batteries, nickel cadmium battery, nickel metal hydride batteries, sodium sulfur batteries, lithium secondary battery, air batteries.
Lithium batteries (Lithium battery) refers to the electrochemical system containing lithium (including metal lithium, lithium metal and lithium ion, lithium polymer) batteriesLithium battery can be roughly divided into two categories: lithium battery and lithium ion batteries.
In recent years, with the rapid development of new energy industry, new energy vehicles power battery Industry grows, The battery Factory is becoming more and more high to the requirement of automation and compatibilityOn December 27-28, by the starting point for research data, sponsored by the starting point of electric network, lithium TV university "2017 apec & new energy cars lithium battery leaders summit starting point and the third international awards "in the crowne plaza Shenzhen longgang pearl river Julong hall.
The supply of lithium salt market is not diminished, and the subsidy of the new policy is approaching to compress the demand of the middle and lower reaches, resulting in oversupply in the short term It is expected to continue to decline slightly before mid-June.
Lithium-ion batteries are the most dynamic and fastest-growing battery products in the battery market today From a development perspective, the main challenge for battery manufacturers has been the continued consumer demand for greater energy density, regardless of volumetric energy density or the weight energy density.
Those companies that convinced at the beginning of the year how to achieve at the end of the year, whether they are shrinking or not; those enterprises that have achieved fruitful results in the "golden" craze of lithium batteries have forgotten their original dependence after repenting in the sudden changes in policy Regardless of how turbulent this year, people who are lithium batteries have to admit that 2017 is really exciting.
On May 22-23, the "2018 First New Energy Vehicle and Power Battery (CIBF Shenzhen) International Exchange Conference" was held at the Shenzhen Convention and Exhibition Center Kaizheng Fang, Director of the Power Battery Industry Development Research Office of China Automotive Technology and Research Center Co.
