Performance of manufactured batteries has improved over time. For example, from 1991 to 2005 the energy capacity per price of lithium-ion batteries improved more than ten-fold, from 0.3 W·h per dollar to over 3 W·h per dollar. [146] In the period from 2011 to 2017, progress has averaged 7.5% annually. [147]
Battery recycling is a recycling activity that aims to reduce the number of batteries being disposed as municipal solid waste.Batteries contain a number of heavy metals and toxic chemicals and disposing of them by the same process as regular household waste has raised concerns over soil contamination and water pollution.

In the United States, the Mercury-Containing and Rechargeable Battery Management Act (the Battery Act) (Public law 104-142) [1] was signed into law on May 13, 1996. The purpose of the law was to phase out the use of mercury in batteries and to provide for the efficient and cost-effective collection and recycling, or proper disposal, of used nickel cadmium batteries, small sealed lead-acid ...
Nissan is reusing the batteries from old Leaf electric vehicles to make portable power sources. ... The 14.4-kilogram (32-pound) power source sells for 170,500 yen ($1,170) in Japan. Overseas ...
Aluminium is still very cheap compared to other elements used to build batteries. Aluminium costs $2.51 per kilogram while lithium and nickel cost $12.59 and $17.12 per kilogram respectively. However, one other element typically used in aluminium air as a catalyst in the cathode is silver, which costs about $922 per kilogram (2024 prices). [15]

The cost of a solar PV module make up the largest part of the total investment costs. As per the recent analysis of Solar Power Generation Costs in Japan 2021, module unit prices fell sharply. In 2018, the average price was close to 60,000 yen/kW, but by 2021 it is estimated at 30,000 yen/kW, so cost is reduced by almost half.
