Lead–acid batteries (Pb-acid) batteries were the first rechargeable batteries ever produced. The original Pb-acid battery was composed of two lead electrodes immersed in a sulfuric acid electrolyte .
Over 90,000 battery inventions from the period 2000-2019 analyzed. Patent data explored from technometric and textmetric perspectives. Global battery patenting activity growth mostly originating in Asia. Three country clusters emerge with different circularity potentials. Battery advances so far suggest incomplete circular transition.
To be very clear: This especially means that the lithium-ion battery category does not contain any patent families tagged as solid-state battery inventions. The fourth step's purpose was to add patent data related to redox-flow and nickel–hydrogen batteries to the dataset.
The majority of battery patents are found to originate in Asia while high battery patent intensities are revealed in the performance of several Asian and European countries. Overall, a considerable increase in annual battery patenting activity is observed from 2000–2009 to 2010–2019.
Overall, a considerable increase in annual battery patenting activity is observed from 2000–2009 to 2010–2019. Second, we also found that four battery technologies – redox-flow, solid-state, sodium-ion, and lithium–sulfur batteries – have displayed vibrant growth in recent years.
Their patent output related to lead–acid batteries is the lowest of the three clusters and their sodium-ion-related IPF share is close to zero. This cluster contains high-tech industrial nations like the US, Germany, and Taiwan, countries that are known to have explicitly expressed their ambitions in the field of battery technology.

The difference between the two comes with the capacity used while getting to 10.6v, a lead acid battery will use around 45-50% of it''s capacity before reaching the 10.6v mark, whereas a LiFePO4 battery will use around 97% before reaching 10.6v, meaning a lithium battery will last twice as long, if not more than a lead acid battery.
In recent years, the separator for a lead-acid battery, especially for a SLI battery has been required (1) to be lower in electrical resistance, (2) to have excellent oxidation resistance at a high temperature, (3) to prevent penetration and short-circuiting with an active material, (4) to have structures such as a more reliable shape (for example, the shape of a envelope), etc., because
