high rate discharge造句

• Moreover , the batteries can endure long time overcharge with the increase of the koh concentration . the change of koh concentration has little effect on the high rate discharge capability
  而且，随着koh浓度的升高，电池的耐过充性能也越好，在本研究范围内， koh浓度的变化对高倍率性能没太大影响。
• By contrasting the lioh or naoh data to koh at 7m and 8m , the change of the li + or na + concentration has little effect on the discharge capacity , internal resistance , voltage plateau and high rate discharge capability
  通过与koh浓度在7m与8m的数据进行对比，结果发现， li或na离子浓度的改变对放电容量、内阻、电压平台以及高倍率性能影响不明显。
• Optimization of prescription especially additives , conductors and binders of the negative is an efficient and economical approach to improve the performances of ni / mh battery during the high rate discharge phase , but till now the related studies are not enough
  优化mh电极配方，特别是添加剂、导电剂和粘结剂是快速提高电池大电流放电性能的一个有效和经济的途径，而这方面的研究还比较少。
• The results show : la2o3 , ceo2 , nd2o3 is applicable for the additives of mh electrode because of the good comprehensive performance of the negative especially during the high rate discharge phase ; y2o3 is not fit as an additive for mh electrode ; the ceo2 content in negative has great effects on the performance during the high rate discharge phase and 2 % ( mass percentage ) is the best one , furthermore , the improvement of purity of ceo2 is beneficial to the comprehensive performance ; the mixture of coo and ceo2 as a additive is more suitable for mh electrode during the high rate discharge phase whose properties are better than that of addition of coo and ceo2 respectively
  研究表明， mh电极中添加la _ 2o _ 3 、 ceo _ 2 、 nd _ 2o _ 3显著提高了电极电化学综合性能，尤其是大电流放电性能，适宜作大电流放电下电池负极的添加剂； y _ 2o _ 3不适宜作负极添加剂； ceo _ 2添加量对大电流放电性能影响较大， ceo _ 2的适宜添加量2wt ；提高ceo _ 2纯度能改善mh电极电化学综合性能。 mh电极中添加coo 、 ceo _ 2复合添加剂后电极综合性能比单独添加coo和ceo _ 2更优良，适宜作大电流放电下电池负极的添加剂。
• Now the ion conductivity of gel polymer electrolyte ( gpe ) can reach the magnitude of 10 - 3s / cm , which can satisfy the practical request . however , it is still lower than that of liquid electrolyte ( 10 - 2 s / cm ) , which causes the fall of high rate discharge and low temperature performance of lithium battery
  目前凝胶聚合物电解质( gpe )的室温离子电导率可达10 ~ ( - 3 ) s cm数量级，已经能基本满足应用的要求，但相比液态电解液的电导率( 10 ~ ( - 2 ) s cm ) ， gpe的电导率仍然偏低，使得凝胶聚合物锂离子电池的高充放电速率和低温性能都大大的降低。
• Ni - cd cylindrical cell has the properties of small internal resistance , long service life , resistant to over charge and discharge , low self discharge , wide operation temperature range ( - 20 + 40 ) and high reliability . they are suitable for high rate discharge and widely used in the fields of electrical tools , railway trains , lighting , fire prevention and military
  镉镍圆柱密封碱性蓄电池具有内阻小，使用寿命长，耐过充过放电，自放电小，使用温度范围宽（ - 20 + 40 ） 、可靠性高等特点，适用高倍率（大功率）放电使用，广泛应用于电动工具、列尾电源、照明、消防、仪器仪表以及军事领域。
• The results show that : nano - nickel powder is not useful for mh electrode during the high rate discharge phase as a conductor or additive ; superfine nickel powder is applicable for the conductor of the negative because of the good performance especially the cyclic stability at 1c rate by using 5 % ( mass percentage ) nickel powder ; the utilization of alloy , specific mass and volume capacity are increased with the decreased particle size of nickel powder in negative , however , the capacity fading rate at 1c discharge rate is also increased , so the capacity and the cyclic stability should be taken into account to make a choice of the particle size
  结果表明： mh电极中加入纳米镍粉对负极的大电流放电性能不利。 mh电极中加入超细镍粉后电极综合性能好，尤其是1c循环稳定性，其最佳添加量为5wt 。减小镍粉粒度提高了电极合金利用率、质量比容量、体积比容量，但增大了负极1c容量衰减率，因此镍粉粒度的选择应综合考虑mh电极容量和循环稳定性。
