Startups are developing new aaa alkaline battery to compete in the battery market

　　When it comes to charging your smartphone or Tesla Model 3 right now, there's nothing better than lithium-ion aaa alkaline battery. Since their introduction in 1991, rechargeable lithium aaa alkaline battery have been the standard in everyday technology devices and electric vehicles.

　　Currently, more than 3 million electric vehicles in the world use lithium-ion aaa alkaline battery. But as the world moves toward an electric vehicle future, it'll need something more efficient than lithium-ion aaa alkaline battery to keep pace. "Lithium aaa alkaline battery have pretty much hit a wall right now. If you really want to increase energy density, you have to adopt a completely different model." Higher energy density means cheaper, lighter and longer range aaa alkaline battery.

　　Fortunately, several battery startups are trying to produce better cells that cost less, have higher energy density, and better performance for supercharging industrial products and consumer technologies, as well as charging faster and driving farther. Longer electric cars. Starting this year, several startups will bring their aaa alkaline battery to the commercial market. These companies believe that their battery technology is a huge improvement over current lithium-ion battery technology.

　　"It took us eight years and probably 35,000 materials synthesis before we had something commercial," said Gene Berdichevsky, CEO of Sila Nanotechnologies. Sila is just one of several battery startups that recently received significant funding to continue Adjust battery technology. Last year, the Alameda, California-based company took on a $70 million Series D round from several investors, including Siemens Global Ventures, to build its first commercial silicon anode cell production line.

　　This comes exactly ten years after Berdichevsky, the seventh employee at Elon Musk’s Tesla, a mechanical and energy engineer, became the company’s co-founder. Berdiszewski once led the development of the battery system for the Tesla Roadster. The Tesla Roadster sports car was once launched into space orbit by Musk's SpaceX.

　　Return on investment is coming

　　New changes in lithium-ion aaa alkaline battery have taken about 10 years to research. Only now are startups starting to prepare for the commercial spotlight, a rollout that will take at least a few years and possibly a full decade.

　　"One car requires the same material as 10,000 smartphones or 1,000 smart watches," Berdiszewski said. "We'll start with consumer devices. Over the next five years, we'll expand with automotive partners."

　　One of Sila's current automotive partners is BMW.

　　Current lithium-ion aaa alkaline battery are limited in materials and physical energy density. The new battery technology aims to improve the safety and energy efficiency of lithium-ion aaa alkaline battery so that there is no risk of fire even if the battery overheats or becomes damaged.

　　Every lithium-ion battery is made up of four basic parts: the positive and negative electrodes (the electrodes at the ends of every lithium-ion battery), a liquid electrolyte, and a separator. When the electrolyte carries lithium ions through the separator to and from the anode and cathode, positive and negative currents are generated. It is this process that creates the electricity stored in the battery.

　　If the chemicals that make up the anode and cathode—graphite and a certain metal oxide, respectively—get too hot, they destroy the physical separator, exposing the highly flammable electrolyte. Think back to the explosion of Samsung Galaxy Note7 mobile phone, and you will find this problem. The current maximum energy density of lithium ions is about 260 watt-hours per kilogram; by comparison, most current electric vehicles operate at 220 to 250 watt-hours per kilogram.

　　next generation prosperity

　　Solid-state aaa alkaline battery are a new battery technology that not only replaces the graphite anode with an anode made of lithium metal, but also replaces the liquid electrolyte and separator with a solid piece (usually ceramic, glass or flame-retardant polymer). Taking this approach is Colorado-based solid-state battery maker SolidPower, which raised $20 million in Series A funding in 2018. According to company executives, the aaa alkaline battery they are developing can increase energy density by at least 50%.

　　QuantumScape, a subsidiary of the mysterious Stanford University, is also working with Volkswagen on solid-state aaa alkaline battery. Last year Volkswagen increased its investment by $100 million. The San Jose-based startup is valued at $1.75 billion, according to PitchBook.

　　According to a press release announcing the deal, QuantumScape's battery can allow Volkswagen's E-Golf to travel 466 miles on a single charge (compared with its current range of 186 miles), making it comparable to the range of traditional natural gas-powered vehicles. Volkswagen says QuantumScape's aaa alkaline battery should charge faster and be lighter than current lithium-ion aaa alkaline battery.

　　"Lithium aaa alkaline battery have almost hit a wall now. If you want to increase energy density, you have to adopt a completely different model." - Yifei Mo, professor of materials science and engineering at the University of Maryland.

　　However, as a Nissan vice president said last year, solid-state aaa alkaline battery may not be fully available until sometime in the next decade. Even QuantumScape's press release announced a 2025 commercial production target. The longer timetable for solid-state technology is to address how current battery factories are built.

　　They were originally designed to use liquid electrolytes to handle the production of lithium-ion aaa alkaline battery, and switching to solid materials is more than just changing the production process on the factory floor. "This is an emerging technology that is in the very, very early stages of commercialization," said Dean Frankel, SolidPower's director of business development. “From a scaling perspective, it just takes time.”

　　While some startups are working to perfect and scale solid-state aaa alkaline battery, others like Sila Nanotechnologies hope to leverage current lithium-ion manufacturing processes to bring aaa alkaline battery to market quickly. Rather than making a solid-state battery, Sila replaces the graphite anode with a silicon material that absorbs lithium ions four times faster than graphite.

　　What's more, most lithium-ion aaa alkaline battery with graphite anodes have a charge rate (C-rate) of less than 1%. Startups developing new aaa alkaline battery with silicon anodes say their cells have much higher C-rates, a key differentiator for an electric vehicle future as most people don't want to wait more than an hour to charge their cars. Refueling your car only takes a few minutes.

　　“We can sustain charging 10 times faster than traditional graphite aaa alkaline battery,” said Enevate CEO Roberta Rango. The Irvine, Calif.-based company is developing an under-the-hood battery with a silicon anode. Generation lithium-ion battery, the company has received $111 million in funding, including an investment last year from South Korean battery company LG Chem.

　　Rango said Enevate has been working on its aaa alkaline battery for 10 years and is about a year and a half away from the technology's first commercial applications, most likely in e-bikes and scooters.

　　However, there is a potential drawback to silicon anode aaa alkaline battery: the silicon material expands, which means each charge causes the battery to deteriorate.

　　Both Berdichevsky and Rango said their respective companies have resolved the issue. "Silicon does expand, and that's been one of the challenges in the industry," Lango said. "In our cells, we've been able to control the expansion. Our cell specifications meet the requirements for electric vehicles." These needs? This kind of battery can achieve a charge rate of 80% after being charged and discharged 1,000 times.

　　The long journeys of these start-ups show how difficult it is to advance battery technology. While improvements in the electric vehicle range are certainly one of the main impacts of better aaa alkaline battery, the successor to current lithium-ion aaa alkaline battery is likely to be found in smaller products.

　　"This has to happen in one generation of technological change," Berdiszewski said. "In the 150 years of existing aaa alkaline battery, four commercially relevant chemistries have entered the market. Each time these new chemistries are used, The transition will be harder.”
