It is well known that compaction density is generally affected by true density and material morphologyReal density.

Lead-acid batteryAmong them, lead - acid batteries for the largest number Lead-acid batteries cost the least and are the most commonly used.

At present, the state strongly supports the development of new energy vehicles, and the future of the new energy vehicle industry is not only pure electric vehicles, the development potential of hydrogen fuel cell vehicles can not be underestimated People often worry about its safety, but in fact, hydrogen can be safer than gasoline.

Recently, there is a fire event in the United States with Tesla ModelX The driver died in the accident.

On April 23, Liancheng County of Fujian Province held the signing ceremony of Fujian Liancheng New Energy Lithium Battery Industrial Park Project and related industrial chain projects Deputy Secretary of the County Party Committee, County Governor Lu Sumei, Deputy County Chief Chen Junxiong, member of the county government party group, and Guanlan Mountain Scenic Area Xie Feng, Party Secretary of the Committee, and the relevant leaders of the county and relevant townships attended the signing ceremony.

The power cell technology route is slowly changing the situation of lithium iron phosphate "one of the largest" Since this year, triple battery installed fast catch up, more than many people in the industry expected.

Over the past 3-4 years, lithium battery production has grown at an average annual rate of 30 %, while its price has fallen by two-thirds The major industries driven by clean energy are showing spurt of development! Among them, the growth rate of lithium batteries is the fastest.

With downstream applications accelerating, the 48V micro-hybrid system "storm" seems to be coming "As the first B-class model in China with 48V micro-hybrid system, Borui GE has been listed for more than 20 days, and the order quantity in a city in Shenzhen has exceeded 1,000.

Energy storage technology is the key to solving the problem of the intermittent nature of renewable energy, the inability of the grid to absorb and connect on a large scale, and the bottleneck of charging facilities and battery safety for electric vehicles There are three benefits of energy storage technology to the grid: First, it helps increase the penetration rate of renewable energy and promotes the development of distributed power generation; The second is to improve the stability of the grid and achieve adequate peak adjustment, reduce peak load and corresponding grid investment and power supply investment; Third, promote the liberalization of the electricity market through the design of electricity prices.

First, pay attention to short-circuit situation Polymer lithium-ion batteries are prone to short circuit during charging Including: internal short circuit, external short circuit, etc.
