摘要

本文的目的是根据保加利亚共和国国家恢复和可持续性计划，版本1.5(06.04.2022)[1]，制定关于固定可再生能源存储电池化学选择的指导方针。讨论了传统化学电源、铅酸电池和锂离子电池的主要技术特点。讨论了传统动力化学、铅酸电池和锂离子电池的主要技术特点，并进行了对比分析，指出LTO和LFP是锂化学设计中最适合的，VRLA是铅酸电池设计中最适合的。由于成本高，LTO化学被认为是可行的。经济方面的考虑阐述了2020-2030年期间可再生能源电池化学选择的基本原理。LFP和LA两种化学物质的比较表明，到2020年，LFP具有边际经济优势，到2030年，由于[4]预测未来几年LFP技术将更便宜，LFP将有增加的趋势。LFP技术被推荐为保加利亚最有前途的电力储存设施建设技术，但这并不否认LA化学的未来。

Energy Storage in Bulgaria - Lead Acid or Lithium - Ion Chemistry

The purpose of this paper is to formulate guidelines on the selection of battery chemistry for stationary renewable energy storage in relation to National Plan for Recovery and Sustainability of the Republic of Bulgaria, version 1.5 of 06.04.2022 [1]. The main technical characteristics of traditional chemical sources of electricity, lead-acid and Li-ion batteries are discussed. The main technical characteristics of traditional power chemistries, lead-acid and Li-ion batteries are discussed with the comparative review highlighting LTO and LFP as the most suitable among lithium chemistries and VRLA among lead-acid battery designs. LTO chemistry was rejected as potentially feasible due to its high cost. Economic considerations are set out on the rationale for the selection of battery chemistry for RES for the period 2020–2030. The comparison of the two chemistries LFP and LA shows a marginal economic advantage of LFP towards 2020 with a trend towards increasing by 2030 due to the forecast in [4] of cheaper LFP technology in the coming years. LFP technology has been recommended as the most promising for the construction of electricity storage facilities in Bulgaria, but without denying the future of LA chemistry.
