The billion dollar race to fix phone batteries
TechAltar・15 minutes read
The evolution of smartphone batteries has seen significant improvements in capacity and charging speeds over the years, with competitors now surpassing leading brands by a large margin. However, the slow growth of battery technology compared to other components has hindered progress in electronics, leading to the development of new promising battery technologies to address these limitations.
Insights
- The evolution of smartphone batteries has been significant, with Apple, Google, and Samsung tripling battery capacities and improving charging speeds over the last decade. Despite this progress, competitors have surpassed these brands with phones reaching 6,000 milliamp hours and 150 watts in charging speeds, highlighting a 30x improvement.
- The introduction of lithium-ion batteries by Sony in 1991 revolutionized the electronics industry, becoming the standard choice for various applications. However, the demand for materials like cobalt, nickel, and lithium for these batteries has raised environmental and ethical concerns due to unsustainable mining practices, necessitating the exploration of new battery technologies like sodium-ion, solid-state, and lithium iron phosphate batteries for a sustainable future.
