According to Kyodo News reported on February 27, Toshiba revealed on the 26th that it has developed a new lithium-ion battery that can be quickly recharged and has a long life. It is reported that when used in small electric vehicles (EV), it can travel 320 kilometers in 6 minutes of charging, which is about 3 times that of the past. Toshiba strives to achieve mass production in the first half of the 2020s.
It has been confirmed that even if the battery is repeatedly charged and discharged 5000 times, it can still maintain more than 90% of the battery capacity. The increase in battery life will not significantly reduce the value of second-hand EV, the person in charge publicized that "this is a battery with both convenience and economy."
The oxide using rare metal "niobium" as one of the materials is used as the negative electrode of the battery, realizing the large capacity of the battery. Niobium is also used as an additive in automotive steel to improve durability. In order to achieve mass production of new batteries, Toshiba, Brazil ’s mining companies and Sojitz have launched joint development of negative electrode materials.
Toshiba supplies car batteries for Suzuki and Mitsubishi, but it has less influence than Panasonic and others. Toshiba believes that with the expansion of "shared cars", the demand for fast rechargeable batteries will increase, hoping to reverse the situation.
A fence is a fence.
Guardrail --- This refers to the "guardrail" for industrial use. Fences are mainly used for the protection and protection of personal safety and equipment in residential, highway, commercial areas, public places and other occasions. Guardrails are everywhere in our lives. Depending on the height, the price per fence length will vary.
The guardrail is usually made of steel, such as stainless steel, round steel pipe, square steel pipe or profiled steel plate, and iron wire. Surface treatment process: fully automatic electrostatic powder spraying (that is, plastic spraying) or painting. In recent years, plug-in, assembled guardrails made of aluminum alloy have also become more popular.
The posts of the guardrail are fixed to the ground by expansion bolts. It is usually installed on two sides of the logistics channel, the periphery of production equipment, the corners of buildings, the sides of doors and the edges of cargo tables, etc.
Effectively reduce the damage to equipment and facilities caused by accidental impact when the transportation equipment is shuttled.
Fence materials are: aluminum alloy, martensitic (nodular cast iron), carbon steel (sprayed or galvanized), stainless steel, plastic steel, zinc steel, PVC and other metal fences.
In addition, it also protects the logistics handling equipment itself. (Such as the protective fence on the edge of the loading platform to prevent the accidental fall of the forklift)
