铅酸蓄电池生物大分子修复技术验证及机理研究

Verification and mechanism study of biomacromolecule repair technology for leadacid batteries

劣化蓄电池若未发生物理劣化,是能够加以修复,并可以继续利用的,从而提高蓄电池的利用率。目前蓄电池的修复多采用物理修复方法,而采用生物大分子修复的方法未见相关研究。对一种铅酸蓄电池生物大分子修复技术进行效果验证。对已退运的铅酸蓄电池,从安全气阀孔注入生物大分子修复剂进行修复,并测试修复前后的蓄电池10 h率容量。测试发现生物大分子修复剂能实现对非物理劣化铅酸蓄电池的容量修复,但对一些严重失效的蓄电池修复效果有限。通过电镜检测,发现生物大分子修复剂能在蓄电池正极板表面上覆盖一层生物大分子,起到延缓极板劣化的作用;生物大分子修复剂能在蓄电池负极板上消除大颗粒硫酸铅结晶,从而提升蓄电池容量。

If there is no physical deterioration of the deteriorated battery,it can be repaired and used continuously,thus improving the utilization rate of the battery.At present,physical repair methods are mostly purchased for battery repair,while biomacromolecule repair methods have not been studied.The effect of a biomacromolecule repair technology for lead-acid batteries is verified.The returned lead-acid battery was repaired by injecting biomacromolecule repair agent from the safety gas valve hole,and the 1o hour rate capacity of the battery before and after repair is tested.It is found that the biomacromolecule repair agent could repair the capacity of no physically deteriorated lead-acid batteries,but the repair effect is limited for some seriously failed batteries.In this paper,the electron microscope detection shows that the biomacromolecule repair agent can cover the surface of the positive plate of the battery with a layer of biomacromolecule,which plays a role in delaying the deterioration of the plate;Biomacromolecular repair agent can eliminate large particles of lead sulfate crystals on the negative plate of the battery,thus improving the battery capacity.
