(1) alkaline cadmium - nickel battery shell material present, the commonly used shell materials are mainly nylon, polystyrene and high density polyethylene plastic, but also the use of modified polystyrene plastic housing. The nylon plastic shell is often used nylon -68, in addition, nylon -6, nylon -610, -610 nylon, nylon -1,010 can also be used, can result due to choose.
HDPE shell which is better than PA and PS shell. HDPE is a crystalline plastics, fine chemical stability, good strength and toughness, wide temperature range, between the -70 ~ 90 β. HDPE shell, but prone to expansion in the use of distortion, while there is easy to aging defects. To overcome this shortcoming, VGP-BPS12 battery and more using a variety of stabilizing agent to improve the performance of HDPE. Are reported in the literature, comparing PA, LDPE, ABS, HDPE and modified the PE properties were: modified HDPE best performance to meet the technical requirements of the battery, is a better shell material.
β΅ zinc - silver zinc battery casing materials - silver battery shell material mainly PS, PMMA, AS, ABS, PE and PA and so on. PS which has good chemical stability, excellent electrical insulation properties, easy processing, low cost, but the use of low temperature is not easy to do too brittle to withstand vibration of the battery case. PA shell off a good vibration resistance and impact resistance, but low intensity is not ideal. PMMA is a transparent plastic relative density, low water absorption, easy to seal; with alkali stability, but poor seismic so easily in a stress crack.
According to documents introduced: zinc - silver battery shell material, multi-use high impact polyethylene - acrylonitrile copolymer (AS); ABS and polyphenylene oxide (PPO) plastic manufacturing the battery case, IdeaPad U350W battery the successful use of aircraft in the short space , alkaline battery case material mainly of some transparent or translucent plastic, the plastic performance requirements on the use of more comprehensive, in particular, to have good toughness, wide temperature range and long service life .
