The lithium-ion batteries segment dominates the global market and is expected to expand substantially over the forecast period. Lithium-ion (Li-ion) batteries allow for the same ampere-hours in and out and are nearly 100% efficient in charge and discharge. The demand for battery energy storage is likely to rise in tandem with the capacity of solar rooftop systems. As a result, it is anticipated that during the forecast period, demand for lithium-ion batteries will increase due to the development of new energy storage systems (ESS) for residential applications. In addition, lithium-ion batteries are preferred for this application due to their lighter weight, quicker charging times, a higher number of charging cycles, and decreasing cost. Li-ion batteries are becoming increasingly popular because they are the strongest rechargeable batteries.

Additionally, the use of Li-ion batteries is increasing, replacing conventional batteries due to its techno-economic benefits. Moreover, leading battery manufacturers are creating new models of energy storage systems for residential applications. For instance, in September 2021, Belgian storage system manufacturer launched AQ-Lith Energybox, a lithium-ion battery for residential PV installations with an eight-year guarantee; it comprises a Multiplus II inverter manufactured by Netherlands-based Victron Energy.

The lead acid battery has a low energy-to-weight ratio but can deliver significant surge currents, indicating a high power-to-weight ratio. When price is more important than energy-to-weight ratio, as in off-grid remote storage, lead-acid batteries are also preferred due to their low cost. Battery energy storage systems are the primary use for lead-acid batteries in the residential sector. The preferred battery type for traditional battery inverter systems is lead-acid batteries. Due to their low price, lead-acid batteries are the most cost-effective option for residential battery-based systems. In addition, flood lead-acid batteries are the most economical choice when weighing cost, capacity, and product cycle life. On the other hand, AGM & GEL VRLA options are also available to offer solutions in cases where a sealed maintenance-free product is needed. Moreover, when properly installed, lead-acid batteries in residential applications do not pose the same risks of fire and explosion as those associated with lithium batteries entering the market.

Some of the other emerging battery energy storage technologies in the global residential energy storage system market include nickel-cadmium batteries, sodium sulfur batteries, and flow batteries, among others. Nickel-cadmium batteries (NiCd) were the most popular rechargeable household batteries until the 1990s. These batteries were meant to be disposed of as hazardous waste due to their low capacity and toxic cadmium content. The market share of NiCd significantly decreased after NiMH batteries entered the market with a triple capacity, non-hazardous materials, and at roughly the same price. Moreover, the market trends for the development of new battery technologies for energy storage systems like nickel-metal hydride (NiMH) batteries, zinc-carbon batteries, sodium batteries, alkaline batteries, and nickel batteries, among others, are likely to be bolstered by the skyrocketing demand for rooftop solar PV installations and growing concerns about climate change.
