“…However, lignosulfonate has the disadvantage of poor electrical conductivity. Given this, Jana [68] studied the cycling stability of different sodium lignosulfonates as expansion agents on lead‐acid batteries, and found that low‐purity sodium lignosulfonates only showed good charge acceptance in the early stages of the cycle, but the polarization resistance increased significantly in the later stages. In addition, the high‐purity sodium lignosulfonates showed better long‐term cycle stability and stable polarization resistance.…”

As one of the key raw materials that replace petroleum materials in today‘s world, biomass resources could be regarded as a promising resource. Currently, lignin and its derivatives are the only lignocellulosic biomass found to possess aromatic rings. Extending the application area of lignin requires overcoming the limitations of its low hydrophilicity. Sulfonation process becomes the most effective method for preparing lignosulfonates. An analysis of the mechanisms by which different lignosulfonates are prepared. It compared the effects of various modification methods on charge density and sulfonate group content in lignosulfonates. It also examined how different separation techniques affect the properties of lignosulfonates. As a result of being more water‐soluble, there is also a review of cutting‐edge research in the fields of energy, medicine, and agriculture. Also, the possible uses of lignosulfonate are talked about, and ideas are given for how this compound could be improved in the future.

“…This potential can be suitably converted to further uses and bring immediate savings in fuel consumption by improving the operating parameters of the machines, respectively extending the lifecycle in terms of reducing wear of individual parts, and thus extended service intervals [2,3]. Since mining industry is energy intensive sector, a lot of approaches that can reduced energy demands are studied including use of renewable energy sources or energy storage [5][6][7]. A small range of industrial applications and technology is dealing with useful heat, i.e.…”

The paper deals with the application potential analysis of heat accumulators for mining machines working in cold climatic conditions. The proposed concept works with the idea of accumulating waste heat generated by the operation of an internal combustion engine, with use of exhaust heat, heat from the radiator and heat from the drive of the hydraulic system. An important innovative element is the use of the heterogeneous structure of phase change material - sodium acetate as a storage substance and a metal foam matrix. The use of sodium acetate enable to store heat for a long period of time without heat loss and the metal foam matrix significantly increases the thermal conductivity. The presented paper deals with the analysis of the functionality of the heat accumulator prototype and with the description of the key phase of the working cycle - heat accumulation.
