The reporter learned from Jilin University that the team of Lin Haibo of the School of Chemistry of Jilin University was the first in the world to prepare high-performance battery-grade carbon materials from rice husks, and used this material to develop a cost-effective lead-carbon battery with performance reaching the international advanced level . A few days ago, the scientific research achievements have built a 100-ton supercapacitor carbon and a 1,000-ton battery carbon production line.
Lead-acid batteries are one of the most widely used batteries. In 2005, scientists combined lead-acid batteries and supercapacitors to invent super batteries (lead-carbon batteries). Compared with traditional lead-acid batteries, their performance indicators have been significantly improved. Lead-carbon battery is called a new generation of lead-acid battery, which is the current research hotspot in the field of international lead-acid batteries.
After more than 10 years of hard work, the team has overcome key technologies such as the green preparation process of biomass rice husk-based capacitor carbon, rice husk-based battery carbon additives, and negative electrodes for lead-carbon batteries, and developed high-cost lead-carbon batteries. Compared with ordinary lead-acid batteries, the cycle life of lead-carbon batteries is increased by 6 times, the charging speed is increased by 8 times, and the discharge power is increased by 3 times. At the same time, it has the advantage of low cost.
This achievement has realized the complete industrial chain of rice husk-based battery carbon materials, lead-carbon batteries and product applications, mainly used in the field of automobile start-stop power supply, automobile hybrid power and energy storage. (Reporters Meng Hanqi, Zhang Boyu)
Low carbon USS flat washers, typically used with Grade 8 or hardened steel bolting, are used under bolt heads or nuts to increase the bearing surface area, or to offer protection so that the nut or bolt can be rotated without distortion of the bearing surface. Flat washers are also used to give tightness to a joint, to prevent leakage, and especially to distribute pressure under the head of a bolt or nut. Dimensional specifications are governed by ASME B18.21.1. USS (United States Standard) flat washers have a larger outer diameter than SAE (Society of Automotive Engineers) flat washers, and can be utilized in nearly any application. ASTM F844 covers the standard specifications for unhardened steel flat washers for general use. Available in zinc plated finish. Zinc plating sacrifices itself, corroding before the base material, offering added corrosion resistance.
