METHOD TO PRODUCE CATHODE MATERIAL FOR CHEMICAL CURRENT SOURCES |
| 摘要 |
FIELD: electrical engineering.SUBSTANCE: hydrolised lignin is milled till particle size is 0.1-1.0 mm, treated with 5% hydrochloric acid at weight ratio 1:(4.5-5.5) during at least 1.0 h and centrifuged with the sediment washed. The obtained sediment is treated with 5% hydrofluoric acid at weight ratio 1:(4.5-5.5) during at least 1.0 h and centrifuged with the sediment washed and dried.EFFECT: cathode material energy capacity and electric conductivity improvement combined with simultaneous simplification of the method and its hardware as well as produced material prime cost reduction.1 dwg, 4 ex |
