How do you rate the battery technology? It is obvious that the battery technology progresses innovatively. A report by the European Patent Office and International Energy Agency proves a gradual growth of battery technology since 2000. And also, it gives a forecast on where and how it will continue in future.
The European Patent Office (EPO) offered registrations for 1029 battery related patents in 2000. By 2018, this International Patent Families (IPF) have risen up to 7153 within two decades. It seemed a faster rising of battery related-patents after 2005 compared to other type of patents. This amount was an average of 14%, year by year.
A spokesperson from EPO has said that 91% of stationary energy is achieved by pumped hydropower at present. However, they expect an innovative growth in stationary battery technologies. Further he expressed, “Given that the requirements for stationary storage are set to become more diverse and more demanding as the share of variable renewable electricity rises, we expect innovation in batteries will need to rise further, in parallel with innovations in non-battery stationary electricity storage, especially for longer duration storage.”
Stationary batteries depicted a smaller fall compared to Lithium-ion batteries in the past decade. A spokesperson from EPO told, “So far, the boom in batteries has been driven by lithium-ion [cells], which can indeed generate spill-overs for stationary applications (see for example Tesla powerwalls).” Considering the stationary storage Lithium-ion is not the best technology option.
Battery Management systems and reading for energy levels have become benefitted in innovation electric automobile. The integrated energy storage and preservation of batteries led towards energy management systems.
In 2019, the annual demand for all types of battery lied at 200GWh. IEA expects with increment of it to 10TWh in 2040. However, utility-scale electricity storage representing a much larger share of the market. By 2040, they predict 55GW of throughput capacity. As development spurs innovation, this suggests that the “golden age” of utility-scale battery storage could be yet to come.
Japan has occupied the first most place for battery development. Korea stood as the second with half of the number of IPS that Japan creates. Samsung from Korea has occupied the first position in the top 10 list. But Japanese companies represents the majority of the list like Toyota, Hitachi, Sony, NEC, Nissan, and Toshiba.
Even though Japanese car companies make these batter innovations, as a country produce only 2% of global electric car sales. Compared to that China rises with 50% since they are standing out of top 10. Japan’s dominance only falters in the smaller field of mechanical energy storage. European inventors hold the most patents followed by the US. European inventors also have a strong stake in thermal energy storage. However, where their share of patents is only slightly smaller than Japan’s.
