Understand the production characteristics of lithium batteries

Lithium-ion batteries can be recharged, and their safety, specific capacity, self-discharge rate and cost performance are better than lithium-ion batteries. Limited by their high-tech requirements, companies in only a handful of countries are producing lithium-metal batteries. Operation principle of lithium battery: lithium battery generally uses manganese dioxide as cathode material, lithium metal or its alloy metal as cathode material and non-aqueous electrolyte solution. Discharge reaction: LiMnO2 =LiMnO2 Lithium battery: lithium ion battery generally choose lithium alloy metal oxide as the positive data, graphite as the negative data, non-hydrolysate. The reaction at the positive electrode of the charge is LiCoO2=Li (1-x) CoO2 xLi Xe - (electrons).

Market analysis of wire harness processing equipment at home and abroad

The domestic automobile industry started late, but it develops very fast. With the new rise of new energy vehicles, the process upgrading of consumer electronics, and the continuous updating of automation equipment, the Chinese market has become the growth engine of the global wiring harness industry, and the wiring harness industry is also facing new opportunities and challenges. According to The chairman of Junquan Automation Ni Junquan revealed in a recent interview, the domestic private wire harness factory has achieved large-scale, penetration rate is also rapidly improving. Domestic equipment has been recognized by customers for its high cost performance, fast response and low after-sales cost, and has a large market advantage in price and after-sales service. However, the domestic equipment factory is too slow to digest the core technology of the world leader, especially in terms of intelligence. To develop rapidly, it is necessary to respect and meet the core demand of wire harness factory for quality, technology and cost of new energy vehicle wire harness.

Understand the production characteristics of lithium batteries

Lithium battery is a kind of lithium metal or lithium alloy as positive/negative data, the use of non-aqueous electrolyte solution of the battery. Lithium batteries have very low self-discharge rate, steep discharge voltage and other advantages, so that implanted pacemakers can run for a long time without recharging. Lithium battery general nominal voltage is higher than 3.0 volts, more suitable for integrated circuit power supply. Manganese dioxide batteries are widely used in calculators, digital cameras and watches. In order to develop more functional categories, people have studied various materials to produce unprecedented products. With the development of science and technology, lithium batteries have become the mainstream. Lithium batteries can be roughly divided into two types: lithium metal batteries and lithium ion batteries. Lithium-ion batteries can be recharged, and their safety, specific capacity, self-discharge rate and cost performance are better than lithium-ion batteries. Limited by their high-tech requirements, companies in only a handful of countries are producing lithium-metal batteries. Operation principle of lithium battery: lithium battery generally uses manganese dioxide as cathode material, lithium metal or its alloy metal as cathode material and non-aqueous electrolyte solution.

Market analysis of wire harness processing equipment at home and abroad

In general, wiring harness processing is a very mature industry. But the industry, which has been around for more than 30 years, is still constrained by labor and skilled workers. "Low-cost" manual processing, in today's manufacturing industry, is no longer the main attraction for customers. Especially in the automotive industry, which requires a high level of consistency, more and more machinery is involved, less and less manual links, so that efficiency, yield, consistency and overall cost reach new heights. How to improve the proportion of automated production and mechanical manufacturing, rather than in the labor production mode, has been a new issue in wire harness processing industry. Foreign wire harness processing equipment is relatively advanced. On the one hand, industrial equipment wire harness stems from the early start of the automotive industry in the region where it is located. Almost all equipment manufacturers have accumulated corresponding strong application technology for many years. The brand identity, quality identity, especially the higher technology identity established by the imported equipment manufacturers and foreign and joint venture wire harness factories on the basis of the previous cooperation, makes the imported equipment occupy a larger share in the Chinese market. For example, European Komax and Schleuniger, And Japanese Shin Ming and ShinMaywa and Kamu JAM.

Lithium ion electrical knowledge

Maintenance instructions Charging shall not be higher than the maximum charging voltage and discharging shall not be lower than the minimum operating voltage. Lithium ion batteries must be kept above the minimum operating voltage at any time. Overdischarge or self-discharge reaction of low voltage will lead to decomposition and destruction of lithium ion active substances, which may not necessarily be reducible. Any form of overcharging of lithium-ion batteries can cause serious damage to battery performance and even explosion. Overcharge of lithium ion battery must be avoided in the charging process. Do not often deep discharge, deep charge. However, after every 30 or so charge cycles, the power detection chip automatically performs a deep discharge and deep charge to accurately assess the state of the battery. Avoid high temperatures, shorten life at best, and cause explosions at worst. Store in refrigerator if possible. Remove the lithium-ion battery strip from your laptop if it is running on AC power to prevent heat from the laptop. Avoid freezing, but the freezing point of most lithium ion battery electrolyte solutions is at -40℃, which is not easy to freeze.

Wire harness processing plant to tell you the choice of wire harness what skills

1: the ambient temperature of the engine is high, and there are more corrosive gases and liquids. Therefore, the wire of the engine wiring harness must use wire resistant to high temperature, oil, vibration and friction. 2: the wire on the automatic transmission is resistant to hydraulic oil, high temperature resistance and good temperature stability. 3: The wire harness on the trunk cover should keep its elasticity at low temperature, so cold elastic wire should be selected to ensure its normal work. 4: weak signal sensor to use shielded wire, such as detonation sensor and crankshaft position sensor, ABS wheel speed sensor, medical equipment wiring harness, etc.. 5:ABS wire harness assembly used 150-200℃ high temperature resistance, outer protective insulation layer hard, wear-resistant, but the wire core should be greater than 133 stranded wire. 6: power line such as starter ac generator output line battery line used for the wire can withstand high current insulation layer heat dissipation performance, voltage reduction special wire.
