We report here that a newly invented pulse activator make it possible to reduce sulphation on the electrode of lead-acid battery resulting the prolongation of the battery life. A high-pulsed current is discharged and then a high pulsed current charging is made. The high current used is 5 to 10 C. Through the battery evaluation test of charging and discharging, the effectiveness of the performance...
Four types of lithium-containing manganese oxide obtained by the LiNO 3 method, namely (i) Li 0.3 MnO 2 obtained from1 mixture of Li molar ratio heated at 320-350 °C; (ii) Li x Mn 2 O y obtained from the mixture with 1.2-1.8 molar ratio ofLiNO 32 heated at 300 °C; (iii) the spinel LiMn 2 O 4 by 1 mixture of LiNO...
