通常安装在家用太阳能系统中的铅酸电池寿命很短。在发展中国家的农村地区，由于缺乏服务或购买新电池的资金限制，这可能使系统无法正常工作。锂离子（Li-ion）电池具有革命性的特性，如更长的使用寿命、更高的能量和功率密度，以及更好的外部参数容忍度。在本文中，我们提出了锂离子电池在离网农村太阳能家庭系统中作为铅酸电池的理想替代品的潜力。我们认为，大规模生产锂离子电池，以满足工业需求，特别是来自电动汽车工业的需求，将有利于可再生能源，特别是小型太阳能家庭系统。电动汽车是锂离子产业发展的动力之一。它将间接允许发展中国家的农村地区以较低的成本获得电力，以取代效率低下和有害的蜡烛和煤油灯。通过在本研究中建造和展示的原型，我们表明，在发展中国家当地组装的锂离子电池组可以更便宜，并有助于一种技术的出现。我们提出了西非国家经济共同体（ECOWAS）的案例研究。
Lead-acid batteries commonly installed in solar home systems have a short lifespan. In rural areas of developing countries, this may leave systems non-functional because of the lack of service or financial limitations to acquire a new battery. Lithium-ion (Li-ion) batteries present revolutionary attributes, as longer lifespan, higher energy and power densities, as well as better tolerance to external parameters. In this paper we present the potential of Li-ion batteries to be an ideal substitution of lead-acid batteries in off-grid rural solar home systems. We defend that the mass production of Li-ion cells, to respond to industrial demand, particularly from the electric automobile industry, will benefit renewable energy and especially small size solar home systems. The electric automobile is one of the driving forces of Li-ion industry. It will indirectly allow rural zones of developing countries to access electricity at a lower cost to replace inefficient and harmful candles and kerosene lamps. Through the prototypes, built and presented in this study, we show that Li-ion battery packs when assembled locally, in developing countries, could be more affordable and contribute to a form of technological emergence. We present the case study of the Economic Community of West African States (ECOWAS).
