Let us review the 14 key issues of energy storage interpreted and predicted by experts at the end of 2023. Most of the interpretations are very instructive, but the forecasts for Q1, Q6 and Q8 are not very accurate. Nearly 8 months have passed this year. From the data, the price of lithium carbonate has fallen to 75,000 yuan/ton. Following the decline in the price of energy storage cells, the energy storage system has further reduced its price, breaking the forecasts for Q1 and Q6; the forecast for Q8 is that large-capacity cells will be mainly 280Ah, but currently China's first-tier battery cell brands have mass-produced 300+Ah cells, for example, CATL/CALB/REPT628Ah; major manufacturers have begun to race to 500Ah+, for example, EVE's MR series, LFP560K, the capacity has been increased to 628Ah; CATL developed 530Ah. #CELL #BATTERIES #ESS #ENERGYSTORAGE #CATL #CALB #EVE

A series of high-profile car fires have triggered a crisis of confidence in South Korean electric vehicles, with local media calling it "electric car phobia." The public should not focus on the Chinese-made batteries used by many automakers, after all, KIA has also had a fire on 6th August 2024, and KIA uses SK-ON batteries. What we should focus on is the latest progress in solid-state batteries and the acceleration of solid-state battery mass production, which is the fundamental way to solve the safety problem of electric vehicles. #EV #SOLIDSTATEBATTERIES #SKON #BATTERIES #MERCEDESBENZ

Riding the wave of new energy globalization, Chinese lithium battery industry chain companies are accelerating the pace of "going overseas" to build factories in order to further explore and develop vast overseas markets such as Europe, North America, Central and South America, Southeast Asia, the Middle East, and Africa. So, which Chinese lithium companies' overseas production capacity has been put into production or is being planned/built? (Please check the below documents to explore more informations.) What are the reasons for the rush to build factories overseas? What impact will it have on the industrial structure? Next post, I will sort it out. #Lithiumbattery #Globaltrading #NEWENERGY #CATL #BYD #EVE #SUNWODA #SVOLT #FARASIS #EUROBIKE

This article introduces in detail the advantages and disadvantages of lithium battery stacking and winding processes, as well as the five most critical parameters of the battery cell. #batterycell #battery #cell #lithiumion #lithium #stacking #winding #batterypack

The most pressing issue in the lithium battery industry is safety performance, in order to prevent fire and explosion incidents from the root. China's latest draft of the "Safety Requirements for Power Batteries for Electric Vehicles" standard has made the latest additions to the needle PUNCTURE TEST. The core logic of a series of revisions to the new standard is to improve the safety requirements for power batteries. The ultimate goal is to achieve a battery that does not catch fire or explode after thermal runaway occurs, allowing the occupants of the car enough time to escape. #EV #BATTERY #BATTERYPACK #NCM #LITHIUMION #LFP #SODIUMION #SAFETY #PUNCTURETEST #RUNAWAY #EBIKE #BICYCLE #MICROMOBILITY
