A focus in terms of automobile enterprise, is to promote the southeast automobile new energy automobile project fall to the ground and put into operation, the current southeast automobile new energy vehicle research and development ability promote construction project has been based, the total investment of about 150 million yuan, will be officially put into use in March 2019And Fujian Mercedes are also vigorously promote new energy vehicles project, the project total investment of about 6.

According to South Korea "central daily" report, Samsung electronics integrated technology research team developed a new success battery material "graphene ball", than existing lithium ion batteries45% higher than that of charge capacity, charging speed increased by more than 5 times The results of research and development, published online in the journal nature communications.

Polymer battery is betterLithium polymer battery is lithium ion batteries updating and upgrading of products.

The lithium battery is a kind of lithium metal or lithium material as the cathode material of chemical power source, lithium battery emergence and rapid development is with the 60 s and 70 s of the 20th century is closely related to the oil crisis, in recent years, due to various reasons such as environmental protection, and changes in lifestyle (new energy vehicles and smart phones, etc), the market once again set off a "lithium electricity craze ".

The university of Southampton (University of Southampton) and found a new REAP systems cooperative research The lithium batteryAs photovoltaic energy storage device in the system, energy storage efficiency can be improved to 95%, can reduce the cost of solar powerAt present most of the PV systems also use lead-acid The batteryAs energy storage device, but, by contrast, the lithium iron phosphate battery replacement can give full play to its advantages, including higher energy storage efficiency, prolong service life, reduce the unit cost and so on.

New energy vehicles more selling more fire, but how to effectively to waste Power battery Recycling, has been the industry in the thinking of problemFrom August 1, the new energy automobile power storage The battery Recycling management interim measures "(hereinafter referred to as the" method ") formally implemented, power battery recycling, traceability management will tend to the main responsibility.

lead-acid The battery is safe and durable and low cost is more suitable for civilian use Quite many different kinds of lead-acid battery, electric vehicle are so common in the market Power battery Starting batteries, UPS batteries, cars, according to you to choose the appropriate use of field lead-acid battery, cannot mix, function different used in different fields of life will be greatly influenced.

There is mobile power charging treasure the scrap, directly away will pollute the environment? Reporter discovery, more and more people have the confusionCharging treasure what to scrap?Citizens liu home has five charging treasure, also in the cupboard for the two of them.

A, electromotive forceElectromotive force is defined as the difference between the balance of the two electrode electrode potential, in order to lead acid accumulator The battery For example, E = Ф + 0 - Ф - 0 + RT/F * In (alpha - H2SO4 / alpha H2O)Among them: E - electromotive forceФ + 0 - the positive standard electrode potential, its value is 1.

Recently, a "low speed electric car spontaneous combustion and led to the death of a child" has aroused attention Spontaneous model belongs to the electric power, old car instead of walking, such electric car is also more common of low-speed electric cars on the market.
