Recently, Domestic Tesra Model 3 achieved first-scale delivery. Previously, the model had just completed the price adjustment, and the starting price was lowered from 355,800 yuan to 323,800 yuan, plus 2.47 million new energy car financial subsidies, domestic model 3 The actual sales price is already within 300,000 yuan.
This price will once again stimulate my country's new energy auto market. At the beginning of 2020, my country's related concept stocks have risen, and some stocks have repeatedly impacts the daily limit.
Huizhong solar street tissue battery has a long life, low temperature performance, easy maintenance, long use time, and so on.
With the rapid growth of the new energy vehicle market, the demand for power batteries is also soared, and the power battery that my country put into the market has also entered the stage of scale.
China Automotive Technology Research Center predicts that in 2020, my country's power battery will reach 200,000 tons (about 25GWH); 2025, the accumulated retirement amount is about 780,000 tons (about 116GWH), including about 550,000 tons ( The amount of total retiring is 70%) The retired power battery can enter the tradder utilization link, and the power battery recovery is further expanded.
Input investigation data shows that as of January 16, 2020, my country's business scope includes approximately 13,921 companies, and only the number of new business coverage of "battery recovery" is as many as 3185.
Home, the number of related companies is increasing year by year. Among them, the listed companies involved in the recycling of used batteries mainly include Tianqi Shares (002009), Green Mei (002341), Guanghua Technology (002741), Nandu Power Supply (300068), etc. Below let's commend, these listed companies have new progress in the 2019 movement battery recycling:
Guanghua Technology
On February 12, 2019, Guanghua Technology and Chery Wanda Guizhou Bus Co., Ltd. signed a waste power battery recovery cooperation agreement, and the two sides will cooperate in business services such as waste battery recovery and circular recycling power battery materials.

History
The French scientist Nicolas Gautherot observed in 1801 that wires that had been used for electrolysis experiments would themselves provide a small amount of "secondary" current after the main battery had been disconnected.
In 1859, Gaston Planté's lead–acid battery was the first battery that could be recharged by passing a reverse current through it. Planté's first model consisted of two lead sheets separated by rubber strips and rolled into a spiral. His batteries were first used to power the lights in train carriages while stopped at a station.
In 1881, Camille Alphonse Faure invented an improved version that consisted of a lead grid lattice, into which a lead oxide paste was pressed, forming a plate. This design was easier to mass-produce. An early manufacturer (from 1886) of lead–acid batteries was Henri Tudor.
Using a gel electrolyte instead of a liquid allows the battery to be used in different positions without leaking. Gel electrolyte batteries for any position were first used in the 1930s, and in the late 1920s, portable suitcase radio sets allowed the cell to be mounted vertically or horizontally (but not inverted) due to valve design.
In the 1970s, the valve-regulated lead–acid battery (VRLA, or "sealed") was developed, including modern absorbed glass mat (AGM) types, allowing operation in any position.
It was discovered early in 2011 that lead–acid batteries did in fact use some aspects of relativity to function, and to a lesser degree liquid metal and molten-salt batteries such as the Ca–Sb and Sn–Bi also use this effect.
Introduction
Lead acid batteries are the most commonly used type of battery in photovoltaic systems. Although lead acid batteries have a low energy density, only moderate efficiency and high maintenance requirements, they also have a long lifetime and low costs compared to other battery types. One of the singular advantages of lead acid batteries is that they are the most commonly used form of battery for most rechargeable battery applications (for example, in starting car engines), and therefore have a well-established established, mature technology base.
