Midsummer comes, lithium electricity industry will usher in its summer?From the point of the whole industry, held in May CIBF show, showing the major exhibitors home studying achievement in the past two yearsAnd for new energy vehicles, passenger car structure adjustment, but at the moment to car companies ready, many class A and A0 level model is gaining momentum.

Coating is lithium ion battery the key links of the anode production, good cathode material for the battery properties, such as capacity has a direct impactSo-called polymer coating is refers to paste, molten polymers or polymer solution coating on the thin film composite membrane was made by the way, for the lithium ion battery, coating and substrate (film) is a metal foil, usually for copper foil or aluminum foil.

The battery in the process of charging and discharging voltage is the comprehensive reflection of battery state of thermodynamics and kinetics, both affected by the influence of battery production process conditions in various processes, and the battery charge and discharge current, temperature, time, and in the process of using in the process of accidental factors resulting in individual batteries in the battery voltage value can't be exactly the sameImprovement measures1, the production process measures, battery companies control the consistency of all kinds of materials;Monitoring the rheological properties of paste, not size, length of time guarantee pulp during coating rheological property is the same;Coating parameter monitoring, especially the lithium iron phosphate slurry, due to the lithium iron phosphate grains finer, pulp processing performance is poor, should be paid attention to during coating coater go slow speed;The reasonable of pulp viscosity detection;A visual inspection of pole piece;To eliminate defective pole piece;Pole piece weighing;Liquid injection before and after the poor quality of the battery;To temperature;Humidity control;Establish standards for all kinds of raw materials, in strict accordance with the standard of raw material inspection and storage;The consistency of the production process control;Consistency for fine control of production process;The technological process according to statistical process control (SPC);To ensure that every process within the prescribed limits of tolerance;To ensure that the process capability index, which follow the production parameters of normal distribution.

At present our country's 12 v lithium battery anode materials mainly include cobalt acid lithium, ternary material,Manganese acid lithium and lithium iron phosphateDivide the anode material of application fields, current lithium cobalt acid lithium is still a small electric field the main anode material, mainly used in the traditional field of 3 c, etc.

If you want to make themselves lithium battery service life is extended as far as possible, must do the following:1, charging, select the appropriate charger, give battery supply * suitable voltage and current2,Lithium battery custom may purchase, must be custom or bid with reasonable protection plate lithium battery3, prevent abnormal battery or charging line power, found abnormal disconnect circuit, protection of lithium battery.

Brand nickel metal hydride battery service life of press officials say can charge 500-1000, in fact this is only an ideal value, often short of such a lifeBut as long as reasonable use charger, more in-depth understanding of Ni-Mh batteries, we will still be able to let her do it "longevity".

Nickel metal hydride battery(NI-MH) is improved by nickel cadmium battery (NiCd battery), and the absorbing hydrogen to make the metal (rare earth alloy or the observatory) instead of cadmium (Cd), can be recycled, belongs to the environmental protection batteriesThe advantages and disadvantages of nickel metal hydride batteries (NI-MH) is as follows:The same volume capacity is higher, the common v batteries, for example, nominal capacity is 2900 mah of Ni-Mh batteries (mah), and nickel cadmium battery only 1100 mah (mah).

Since the electric vehicles new GB upcoming news in the industry, lithium electricity has been is not open around the topicMany lead-acid battery brands have been built lithium battery project, the hope can in the future, new GB market pie.

"The lithium battery", is a kind of lithium metal or lithium alloy anode materials, the use of water electrolyte solution of the batteryLithium battery as early as 1912 by GilbertN.

Lithium ion batteries electrolyte is soluble in organic solvents have electrolyte of lithium ionic conductor Generally as a practical lithium ion battery organic electrolyte should possess the following properties:(1) high ionic conductivity, general should reach 10-3 ~ 2 * 10-3 s/cm;Lithium ion transference number can approximate to 1;(2) the electrochemical stability of the wide range of potential;There must be 0 ~ 5 v electrochemical stability window;(3) good thermal stability, the use of wide temperature range;(4) chemical performance is stable, with collection of fluid inside the cells and active substance does not react;(5) safety low toxicity, best able to biodegradation.
