At this stage, the focus of nickel -hydride battery research.photovoltaic energy storage battery direct sales

　　1. Nickel -hydrolytic nickel -hydride battery

　　This research uses ingredients and process optimization to prepare excellent performance -free hydrogen -free alloys. The capacity attenuation rate of nickel -metalized batteries has been reduced by 33%compared with the past, and low temperature performance has also greatly improved. Nickel -hydride batteries are released 6%.

　　2. Nickel -hydride battery in wide temperature zone

　　Under some special conditions, military devices such as field radio stations, aircraft and tanks and very cold areas are required to discharge in an environment of -40 ° C. In order to solve these problems, research institutions have developed nickel -metal hydride batteries on a wide temperature zone on the basis of successful development of hydrogen alloys. This battery works reliable under low temperature conditions.

　　3. Lifeon storage hydrogen alloys

　　In recent years, with the development of various new energy vehicles, the demand for high -capacity hydrogen deposits is more urgent. Traditional hydrogen storage alloys are made of pure pupae, and metal cricket prices are very expensive, while titanium -containing alloy alloys are the basis for obtaining relatively low cost, high -capacity 钒 钒 solid -soluble hydrogen storage alloys. Sichuan University's research work in this area has made great progress.

　　4. Benbly storage hydrogen electrode alloys

　　At present, the negative materials of commercialized nickel -metalized batteries are mainly rarety AB; this alloy capacity is only about 300mAh/g. The biggest problem of 钒 钒 钒 钒 钒 钒 is poor in electrochemical catalytic activity in alkaline solution. Recent work found that temperature has a great impact on the discharge performance of the basal solid -soluble hydrogen storage alloy electrode. The increase in ambient temperature (less than 80 ° C) can release a large amount of capacity of hydrogen storage alloys, indicating that this alloy may become a high -energy density one or secondary nickel -metal hydride battery negative material.

　　That is to say, in general, batteries that start at minus 20 degrees can be called low -temperature batteries. This is difficult for most battery manufacturers.
