基准修正法开发设计异形MH/Ni电池

Developing and designing special-shaped MH/Ni batteries by reference-modification method

基准修正法是以设计合理、经过生产检验已成型的某种规格的MH/Ni电池为参照基准 ,进行缩放 ,并综合考虑电池尺寸特点、用电设备的具体使用要求 ,按照一定的规律进行修正 ,从而对电池极片尺寸、活性物质用量、电解液用量、隔膜尺寸及电池结构等进行优化设计。本研究采用基准修正法成功地开发设计了一系列具有高容量、长寿命 (标准寿命 >80 0次 ,1C5快速充放寿命 >5 0 0次 )、优良的负载特性和高倍率充放电能力、安全可靠。

Reference-modification method,based on a certain type of well-designed battery which had been examined in production process,took battery size and requirements of instruments into consideration,then modified the design parameters according to a certain rule.By doing so,the parameters of the battery such as size of electrodes,amount of active materials,quantity of electrolyte,size of separator were obtained and optimized.Through the reference-modification method,a series of MH/Ni batteries were developed and designed with excellent performances such as high capacity,long cycle life(standard cycle life was over 800 cycles,and charge/discharge at 1 C 5 cycle life surpasses 500 cycles),super discharge characteristics,reliable safety and being friendly to environment.
