Many have heard of AI and they think Terminator. Yet AI in the computer industry has allowed us to build computers and accessories faster due to the ability of AI to sift through data faster than humans can. This brings us to how AI is helping the Auto industry transition to EV's and how battery tech will change much faster than in the last two decades. IBM has announced their recent battery project is developing prototypes of new faster charging batteries that are free of Nickel and Cobalt thanks to AI. It has allowed them to quickly evaluate a set of 20,000 potential compounds for use in the Battery electrolytes. This would normally take 5 years via traditional human research and yet was accomplished in nine days using AI. GM Ultium batteries and Panasonic batteries have reduced testing from three years to about six months. This is going from a large number of time consuming charging and discharging cycles to using AI to cover what would be done manually in three years to six months. Gbatteries has used AI to build faster and more reliable DC fast chargers. InoBat from Slovakian has stated that AI is helping them to boost battery density by 20% with the batteries being sold in 2023. VW has stated AI is helping them lay out a new roadmap of lite weight materials for auto's including their own batteries that are in development. Dyson has claimed that AI is how they have brought Solid State batteries to market now. AI is going to help usher in the next generation of not only Auto's but phones, computers, etc. AI will touch just about every aspect of life for people. https://www.wsj.com/articles/electric-car-batteries-get-a-boost-from-artificial-intelligence-11604422792 https://www.greencarreports.com/news/1130221_report-ai-will-dramatically-speed-up-battery-development-and-thus-ev-adoption https://na.panasonic.com/us/press-releases

Battery Density Starting to Surpass Moore's Law Something old is new, the picture above is the first Thomas Edison Storage Battery. This was an Alkaline Battery that he started developing in 1890 and completed in 1903. As the Auto industry started up, Edison felt that electric auto's was a superior way to go versus steam, gas or any other form that was being played with. Edison found the traditional battery to be toxic, heavy and short life with only average energy storage. In 1903 Edison declaring his battery finished showed off his potassium hydroxide battery that would react with the Iron / Nickel electrodes creating a battery that was reliable and rechargeable. This battery also was 3 times as dense energy wise as traditional lead-acid batteries. Those building electric auto's flocked to buying Edison's batteries. Sadly due to various issues of leakage post manufacturing, electric auto companies did not get the long term benefit they had hoped for and went back to using cheaper to produce lead-acid batteries and Edison closed his battery plant in 1908 and Edison who was friends with Henry Ford acknowledged that the electric auto had lost to the Model T Car. While Edison's battery was of too low a voltage for ICE Auto's to use starting in 1912 when electric start began, they were profitable due to their long life and reliability that allowed them to be used in railroad crossing signs and especially in lamps for use in the mines. These batteries once Edison had fixed the packaging issue became his biggest moneymaker. Now you might ask why the History lesson? Battery density has been a slow but growing segment and many in the computer industry has felt that we are on the cusp of starting to use Moore's law for CPU's in regards to batteries. Reminder ( Moore's law is the observation that the number of transistors in a dense integrated circuit doubles approximately every two years.) Recently, I posted about Toshiba's Generation 2 SCiB batteries that have tripled the density while maintaining charge times using a Titanium Niobium Oxide Anode to charge the battery. Researchers at the University of Maryland in partnership with Brook-haven National Laboratory looked to what had been invented in the past, the issues that existed and if they could possibly improve upon them to overcome limitations to allow a new product to come to market fast. Here is where Edison's battery comes into play as he had already figured out how to triple the density of the battery, but not how to improve the voltage recharge time as the batteries were slow to recharge. The short answer for those not wanting to look at the scientific paper listed below or download the document file is that they have designed due to current technology a new cathode material (Iron Triflouride) that triples energy density of Lithium-ion batteries while reducing recharge times greatly in a stable battery package. As the picture above shows, a traditional button 2032 battery now has triple the energy density of the original battery. Think of your laptop or cell phone battery that would now give you three times as much life before recharging is needed. The end result is that only a year ago we had batteries with a certain density and now 12 months later we are seeing proto types of batteries in their same size but three times as dense. Consider a Chevy Volt in it's current battery pack of 54 miles now 162 mile range or a Chevy BOLT's battery pack of 238 miles now 714 miles. The future is looking shockingly BRIGHT for long range batteries for all sorts of technology from cell-phones, laptop computers to other forms of portable electronics and especially electric auto's.

EV Battery War Heats UP, Asia Versus America! Seems America, Tesla and the department of energy have created the next war. This is the Battery war, Lithium Ion versus Solid State batteries and Japan is behind. As such according to the story in the Nikkei, the Japanese government is funding research by leading Japanese manufacturers to develop what they believe will power the EVs of the future. This group brings together the Japanese Consortium for Lithium Ion Battery Technology and Evaluation Center (Libtec) with Toyota Motor, Nissan Motor, Honda Motor, Panasonic and battery maker GS Yuasa to develop rapid charging solid-state batteries that are easier to manufacture, safer, denser energy and costs less. The story goes on to say that Toyota's Solid State battery technology is considered to be the most advanced in the world, but is not commercialized yet. This new consortium is meant to make this happen by being funded by the Japanese government. This should help Japan beat China, Korea and the US in having the fastest charging, safest and densest battery packs in the world. Current market numbers are that global battery market shows Japan had 70% in 2013 but shrunk to 41% today, China and Korea combine for 26% today from 3% in 2013 The consortium is quoted as bringing the smaller but denser 400km Toyota solid state battery pack to market in the next 18 months in current EVs and have the size grow of the solid state batteries grow very little while having 550km batteries by 2025 and 800km batteries by 2030. For those that are a bit rusty on their metric, this equates to 249, 342, and 497 miles of range in a small dense battery pack. Japan industry ministry is eager for the country to reclaim its global dominance by setting the standard for solid-state batteries. Nikkei Story
