In the development of electric vehicles, Tesla Model3 is a monumental existence Since Tesla introduced the first generation of Model3, the development of electric vehicles has reached a new peak.

The negative electrode is a pole that flows out of the electron when the battery is discharging Lithium-ion batteries mainly use graphite materials as the negative electrode.

A lithium battery is a battery in which a lithium metal or a lithium alloy is used as a negative electrode material, and a lithium battery for a reserve power source in Zhejiang uses a non-aqueous solution Lithium battery was invented in 1912.

Battery capacity is usually expressed in terms of "A/H" Such as:for example,20A / H, ismeans that1 amp discharge,ingcan bemaintained for 20 hours, discharge2 ampsdischargingcan bemaintained for 10 hours.

According to your point of view, the ordinary battery is a primary battery, cannot be charged, the ordinary carbon battery, alkaline battery, and a lithium battery, the advantage is that the price is cheap (relative to the secondary battery, in fact, not much cheaper), The storage time is long, that is, the self-discharge is relatively low, and the weight is low to carry The disadvantage is that it is not rechargeable, and the cost of one use is high.

In real life, people may put lithium batteries and lithium-ion batteries because they are a concept, but different mutual inheritance and development of each other's relationship The so-called lithium battery is a lithium ion battery in which a battery uses metallic lithium as a negative electrode active material, and the anode and cathode of the system use two different lithium compounds, which are capable of reversibly intercalating and deintercalating lithium ions.

Think carefully, there are many similarities in the lithium battery industry and the LED industry For example, in the early stage of the country's strong support, the market prospects are optimistic; the technical threshold is low, the production equipment is easy to purchase; the investment density is not high, and the return period is short.

In the use of electric vehicles, consumers are most worried about the charging time and cruising range Under the current technical level, charging time and cruising range are difficult to achieve, so the power battery has developed two routes, one It is the specific energy class that focuses on the cruising range, mainly by continuously increasing the specific energy of the lithium-ion battery, thereby increasing the cruising range of the electric vehicle.

According to foreign media reports, the batteries of the first batch of electric and hybrid vehicles are approaching the retirement period, but they will not be transported to landfills, but will help ice beer in the 7-Elevens store in Japan to charge cars in California The station stores energy for European homes and the grid.

Leading new track of solid-state batteries, Qing Tao team has started a full layout of solid-state lithium battery in the upstream and downstream business, has realized the diaphragm material, solid-state batteries, the "trinity" of automation equipment development Qing Tao doesn't want to earn a quick buck.
