Moore's Law And Battery Development: Cars Of The Future

Moore's Law, formulated by Intel co-founder Gordon Moore in 1965, states that the number of transistors in an integrated circuit doubles every 18 to 24 months. This has led to rapid improvements in computer processing power, but does Moore's Law apply to other technologies? In this article, we will explore whether Moore's Law can be applied to battery development in cars, specifically electric vehicles (EVs).

Moore's Law and its limitations in biomedical research

Moore's Law, an empirical observation made by Gordon Moore in 1965, states that the number of transistors on a microchip doubles about every two years with minimal cost increases. This has guided the semiconductor industry in long-term planning and setting targets for research and development (R&D).

While Moore's Law has been applied to various fields beyond computing, it does not apply to all technologies. For instance, the maximum speed of cars, planes, or ships has not increased exponentially; maximum speed has barely increased at all.

Moore's Law also does not apply to battery development. This is because the performance of batteries is dictated by their chemistry and the size of ions, which are large and take up space. In contrast, the performance of computer chips is not limited by physical space in the same way, as electrons are small and do not take up space on a chip.

When it comes to biomedical research, Moore's Law has its limitations. While the costs of gene sequencing have come down exponentially, medicine and manufacturing have changed very little since the Human Genome Project. The number of drugs approved by the FDA per billion spent on R&D has halved every nine years since 1950, a trend known as Eroom's Law. This indicates that innovation in biotech is decelerating, contrary to the exponential progress predicted by Moore's Law.

Additionally, the parallels between the information revolution and the supposed bio-revolution have limitations. For example, while many people still receive chemotherapy to treat cancer, few people still use an Apple II computer. This suggests that progress in biotechnology is not keeping pace with progress in computing, and there is no "Moore's Law for Biotech."

In conclusion, while Moore's Law has had a significant impact on computing and various other fields, it does not apply universally. In the case of battery development and biomedical research, there are fundamental differences in the underlying technologies that make the exponential progress described by Moore's Law unlikely to occur.

Moore's Law and its inapplicability to battery development

Moore's Law, formulated by Intel co-founder Gordon Moore in 1965, states that the number of transistors in an integrated circuit will double every 18 to 24 months. This has led to exponential improvements in computer processing power, with performance doubling approximately every two years. However, Moore's Law does not apply to all technologies, and it is particularly inapplicable to battery development in cars.

The public has come to expect that all technologies follow Moore's Law, but this is not the case. For example, the maximum speed of cars, planes, or ships has not increased exponentially; in fact, it has barely increased at all. Similarly, battery technology is subject to different constraints and does not follow the exponential growth predicted by Moore's Law.

The fundamental chemistry of batteries limits their performance. Ions, which transfer charge in batteries, are large and take up space, as do anodes, cathodes, and electrolytes. As a result, battery performance is dictated by the relevant chemical reactions, and significant improvements in battery capacity can only be achieved by changing to a different chemistry. While new battery chemistries, such as lithium-sulfur and lithium-air, are being explored, they are subject to the same fundamental constraints.

In contrast to the rapid progress in computer technology, battery development has been slow and incremental. Scientists and battery experts have expressed diminished optimism about improving lithium-ion batteries, the most common type of battery used in electric vehicles. While there have been some advances, such as the development of lithium-iron phosphate (LFP) batteries, the gains in energy density have been modest compared to the exponential improvements predicted by Moore's Law.

Additionally, safety concerns have arisen with lithium-ion batteries, including fires in Boeing 787 aircraft and in some electric vehicles. These issues further complicate the development and public acceptance of electric cars. While there is ongoing research and investment in battery technology, it is important to recognize that it does not follow Moore's Law, and breakthroughs may not occur at the same rate as in computer technology.

The impact of public perception on Moore's Law

Moore's Law, an empirical observation regarding advancements in computing, states that the number of transistors per square inch on a microchip will double each year while the manufacturing cost per component will halve. This "law" has been applied to various technologies beyond its scope, and the public has come to expect that all technology will follow Moore's Law.

The public's perception of Moore's Law has been influenced by its successful prediction of the reduction in costs for computing power over short periods, approximately every 18 months. This has created an expectation of exponential progress in all technology, which is not always realistic. For example, the speed of cars, planes, and ships has not increased exponentially and has barely improved at all.

The application of Moore's Law to battery development in cars has been a topic of interest. The public has become accustomed to rapid progress in mobile phone and computer technology, but this progress does not directly translate to batteries. The fundamental chemistry of batteries, with large ions and chemical reactions that dictate performance, presents limitations that are not present in transistor technology, where miniaturization is achievable through finer lithography techniques.

The perception that Moore's Law applies universally can lead to a misunderstanding of the challenges in battery development. The public may expect exponential improvements in battery technology, which is not feasible due to the inherent constraints of the technology. This can impact public sentiment and policy decisions regarding electric vehicles and energy efficiency.

While Moore's Law has had a significant impact on the semiconductor industry and related technologies, its applicability to battery development in cars is limited. The public's perception of Moore's Law as a universal principle can shape expectations and influence decisions, but it is important to recognize the inherent differences in technologies and the constraints they face.

The economics of Moore's Law

Moore's Law, formulated by Intel co-founder Gordon Moore in 1965, states that the number of transistors in an integrated circuit will double every 18 to 24 months. This has led to exponential improvements in computer processing power, with capabilities rising correspondingly in areas such as microprocessor processing power and memory capacity. However, Moore's Law is not a physical law, and it does not apply to all technologies.

However, Moore's Law does not apply to all technologies, and it is important to understand its limitations when considering the economics of technological progress. For example, the speed of cars, planes, and ships has not increased exponentially and barely improves at all. Similarly, battery technology, which is crucial for the development of electric vehicles, does not follow Moore's Law.

Battery development is constrained by fundamental chemistry. Unlike transistors, where improvements in lithography techniques have enabled miniaturization, ions in batteries are large and take up space. As a result, improvements in battery capacity are limited and can only be made by changing to a different chemistry. This requires significant time for commercialization and does not follow the rapid pace set by Moore's Law.

While there have been advancements in lithium-ion battery technology, the progress has been incremental rather than exponential. The cost of lithium-ion batteries has been decreasing, but not at the rate specified by Moore's Law. Therefore, when considering the economics of Moore's Law in the context of battery development, it is important to recognize that different technologies have different growth trajectories and are subject to unique constraints.

The future of battery technology

Moore's Law, formulated by Intel co-founder Gordon Moore in 1965, states that the number of transistors in an integrated circuit doubles every 18 to 24 months. This has led to exponential improvements in computer processing power, with capabilities rising in tandem for electronic products such as microprocessors, storage devices, and image sensors. However, Moore's Law does not apply to all technologies, and battery development in cars is one such example.

Battery technology, particularly lithium-ion batteries, has been improving steadily, but not at the exponential rate predicted by Moore's Law. The fundamental chemistry of batteries limits their potential for rapid performance enhancement. Ions, which transfer charge in batteries, are large and occupy space, as do the other battery components. As a result, battery performance is dictated by chemical reactions rather than miniaturization, which is the key driver of Moore's Law for computer processors.

While there have been advancements in lithium-ion battery technology, the improvements have been incremental rather than exponential. Scientists and battery experts have expressed reduced optimism about significant breakthroughs in lithium-ion battery performance and are exploring new battery chemistries, such as lithium-air and lithium-sulfur, to achieve higher energy densities. However, each new technology requires significant time for commercialization, and there are safety concerns with lithium-ion batteries due to recent issues with fires.

Despite the challenges, there is still hope for the future of battery technology. A large-scale research consortium, the Joint Center for Energy Storage Research, has set an ambitious goal of improving energy storage density by five times and reducing costs by five times in five years. Additionally, there is a focus on improving energy efficiency in cars by making them lighter, smaller, and more powerful, which can help reduce the impact of combustion engines on pollution and climate change.

In conclusion, while Moore's Law does not apply to battery development in cars, there are still promising advancements and ongoing efforts to improve battery technology and energy efficiency, which could lead to significant progress in the future.
