How to improve the low temperature performance of lithium batteries
The low-temperature performance of lithium battery is one of the key factors that restrict the widespread use of lithium batteries. How to improve the low-temperature performance of lithium batteries is still a hot and difficult point of current research. The battery system reaction process mainly includes four steps: Li+ transport in the electrolyte, crossing the electrolyte/electrode interface membrane, charge transfer, and Li+ diffusion in the active material body. At low temperatures, the rate of each step decreases, which causes the impedance of each step to increase, which leads to aggravation of electrode polarization, and causes problems such as a decrease in low- temperature discharge capacity and lithium precipitation in the negative electrode. The poor low-temperature performance of lithium-ion batteries is mainly due to the following three factors: At low temperatures, the viscosity of the electrolyte increases, and the conductivity decreases; The electrolyte/electrode interface membrane impedance and charge transfer impedance increase; The migration rate of lithium ions in the active material body is reduced. As a result, the electrode polarization is increased at low temperatures and the charge and discharge capacity is reduced. The mainstream ways to improve the ion diffusion performance of cathode materials at low temperatures are as follows: Use materials with excellent conductivity to coat the active material body to improve the conductivity of the cathode material interface, reduce the interface impedance, and reduce the positive electrode material and the side reaction of the electrolyte stabilizes the material structure. The second is to do bulk-doping of the material body with Mn, Al, Cr, Mg, F and other elements to increase the layer spacing of the material to increase the diffusion rate of Li+ in the body, reduce the diffusion resistance of Li+, and increase the low temperature of the battery. performance. The third is to reduce the particle size of the material and shorten the Li+ migration path. It should be pointed out that this method will increase the specific surface area of the material and increase the side reaction with the electrolyte.

Here's what you need to know about starting the battery
What is a starting battery The battery according to the purpose of classification, can be divided into starting battery, power battery and energy storage battery, power battery is common in E-bike, electric vehicle, electric boat, mainly to provide power for these tools; Starting batteries are used in oil-powered vehicles, such as cars, tractors, and motorcycles, to use high power to ignite internal combustion engines. The starting battery is different from the power battery The starting battery is applied to the starting of the vehicle, the discharge ability is strong, a short time can release more than 10C current, this characteristic determines its volume and capacity is lower than the power battery. The power battery mainly provides power for the vehicle, the maximum discharge current is not more than 1C, and can not be maintained for a long time, often at less than 0.5C power operation, and the battery life is long, because it needs to store more electricity, so the volume and capacity should be larger. The material of the starting battery At present, most of the starting batteries are lead-acid batteries, which is also a relatively large application field of lead-acid batteries. However, due to the gradual attention of environmental protection in various countries, the market for lead-acid starter batteries is gradually compressed, so it is feasible to use lithium iron phosphate batteries as starter batteries. By analyzing the various requirements for starting the battery, it is easy to draw conclusions. The use of lithium iron phosphate is feasible as long as it can meet the characteristics of small size, high discharge rate, and resistance to low and high temperatures. Compared with lead-acid batteries, using lithium iron phosphate starting batteries has the following advantages: However, the application of lithium iron phosphate starter battery in the market is limited at present, which may be related to the high initial investment cost of lithium iron phosphate battery. Another important reason is that users have been used to lead-acid battery, have not tried lithium iron phosphate starter battery, and cannot intuitively feel the advantages of lithium iron phosphate battery.

California Bans Sales of New Gas-powered Cars by 2035. Now the Real Work Begins
Buy a car in 2035 and you won’t have to decide between gasoline, diesel or electric. You won’t have a choice. Citing an urgent need to address climate change while cutting back on air pollution, the California Air Resources Board voted Thursday to require all new cars and light trucks sold by 2035 to be zero-emission vehicles. Lauren Sanchez, Gov. Gavin Newsom’s climate advisor, called it “a huge day not only for California but the entire world.” The mission, she said: “Move the state away from oil.” The move marks a historic turn in the decades-long battle to curb motor vehicle pollution, a momentous shift for consumers, industry, the economy and the environment. California has led the nation in auto emissions regulation since the air resources board was created in 1967 to combat the toxic yellow-brown smog that hung over Los Angeles. The state's large population meant automakers could not ignore California's mandates. Congress gave California permission to set its own rules under the Federal Air Quality Act the same year. California's emissions and fuel efficiency rules have been adopted by more than a dozen other states. Even with that prodigious record, the zero-emission mandate "is the most important and transformative action that [the air resources board] has ever taken," said Dan Sperling, founding director of the Institute of Transportation Studies at UC Davis. The mandate forces automakers to phase out gasoline and diesel cars, sport utility vehicles, minivans and pickup trucks in favor of cleaner versions powered by batteries or fuel cells. If automakers fall short, they could be charged $20,000 per noncomplying car, the air resources board said. If consumers don’t go along? That could cause big problems. But state officials think they will, and the trend line lends confidence. Electric cars are rapidly gaining popularity in California. In 2012, less than 2% of new vehicles sold were electric. That grew to 7% in 2018. But demand has surged since, and now 16% of new cars sold in the state are plug-in vehicles — battery electric, led by Tesla; plug-in hybrid vehicles; and a smattering of cars that run on hydrogen fuel cells. There are now 1.13 million zero-emission vehicles registered in California, according to the air resources board — 43% of the nation’s total. Once considered little more than glorified golf carts with paltry range, electric cars now can travel several hundred miles on a single charge, in models that range from small commuter cars to luxury vehicles to SUVs, pickup trucks and muscle cars. Under the new rules, 35% of new cars must be zero emission by 2026, 68% by 2030, and 100% by 2035. People could still buy internal combustion cars from another state. But many states, including most of its neighbors, tend to follow California’s lead on vehicle emissions policy and are considering mandates of their own. The effects of the 2035 mandate will be far-reaching, the air resources board said. It “will essentially end vehicle emissions altogether,” CARB board Chair Liane Randolph told reporters. Not quite. As Randolph herself noted, owners of internal combustion cars can continue to drive them after 2035. It will still be legal to buy and sell used fossil-fuel cars and light trucks. The mandate doesn’t cover all of highway transportation, either. Heavy trucks that burn diesel fuel will have 10 extra years before they’re banned. A proposed zero-emission mandate for heavy trucks wouldn’t hit 100% until 2045. And even the zero-emission vehicle mandate includes vehicles that are not zero-emission. Up to 20% of a carmaker's sales can be plug-in hybrids, which have both electric motors and gas engines, and still count as zero-emission vehicles, as long as the minimum battery range is 50 miles or more. The state uses “zero-emission” as shorthand, pertaining to the cars themselves as they move along the roadways. Recharging the batteries may well emit significant greenhouse gases, depending on what’s generating the energy: coal, oil and natural gas on the dirtier side; solar, wind, hydropower and nuclear on the cleaner. Creating hydrogen from water for fuel cells requires significant electricity, so greenhouse gas emissions again depend on the source. https://www.aol.com/news/california-bans-sales-gas-powered-204550623.html
