"We will evaluate and publish the white list of automotive batteries and clean fuel cells" On April 26, standing vice President of the China association of automobile manufacturers and BBS Dong Yang, chairman of the organizing committee on the "2018 China automobile BBS" make the welcome speech, said China's new energy vehicles are by policy development period to the critical period of the development of the market-oriented transformation, power battery and clean fuel cell is the core resources in the development of new energy vehicles.

The power battery giant ningde times is about to go public Tianjin lishen, a lithium battery veteran who once stood in the front line, has also launched a battle to rebuild its position in the industry.

"Energy storage is a key technology that plays an important role in FM, auxiliary market FM, peaking, improving energy quality, and increasing the proportion of renewable energy generation "Talking about the importance of energy storage, Wu Jiamang, vice president of the Sunshine Power Supply Division, said frankly.

According to statistics, the global demand for lithium-ion batteries has reached 13 billion, and with the continuous expansion of the application field, this data is increasing year by year.

In 2017, the hottest new energy car industry will be lithium batteries, while the most dazzling non-cobalt in the lithium battery industry will beIn the power lithium battery field, compared to other materials, because of its strong comprehensive advantages in energy density, cost, safety, and stability, ternary materials are being adopted by more and more battery manufacturers; In ternary materials such as lithium nickel-cobalt manganese acid and lithium nickel-cobalt aluminate, the amount of cobalt used is usually one-third, so the demand for cobalt materials has suddenly increased.

In October last year, the "four-wheel low-speed electric vehicle technical conditions" national standard was formally established, one of the relevant policy guidance is the power system from lead-acid battery to upgrade to lithium battery, this guidance has caused greater repercussions in the industry So, what opportunities and challenges will the lithium electrochemical process of low-speed electric vehicles bring? Will the lithium battery upgrade give low-speed electric vehicle enterprises a chance to sublimate? The question is well worth exploring.

Polymer Lithium Battery ProfileAccording to the different electrolyte materials used in lithium-ion batteries, lithium-ion batteries are divided into liquid lithium-ion batteries and polymer lithium-ion batteries or plastic lithium-ion batteries The positive and negative materials used in polymer lithium-ion batteries are the same as liquid lithium-ions.

Pacific Battery Exhibition Press Conference was successfully held in Guangzhou The conference reported on the preparations and new highlights of the 2018 Asia-Pacific Battery Exhibition.

Apple has begun investigating the cause of the incident, which is not the first time an iPhone has been in a safety accident In late January, Samsung also announced the results of the Note7 battery explosion investigation.

Open circuit voltage, as the name suggests, that is, the battery is not connected to any external load or power supply, measurement of the potential difference between the positive and negative electrodes of the battery, that is, the battery open circuit voltage Working voltage, corresponding to the open circuit voltage, that is, the battery is externally connected to the load or power supply, there is a current flow through the battery, the potential difference between the positive and negative poles measured.
