Fill flash is a technique photographers use to brighten deep shadowed areas, especially on gray days or extremely sunny sessions. You can use fill light whenever the background is brighter than the main subject of the photo.
Event photographers in particular get called upon to make portraits in the most unpleasant lighting conditions. Fill light empowers you to retain the location's ambient light, while illuminating your clients with more flattering controlled lighting. When you add flash to your photo setup, you're actually managing two different exposures:
As the term suggests, fill flash adds light to deep shadows cast harsh lighting. You can use fill light whenever the background is brighter than the main subject of the photo. Think of it as a supplementary light source that can reduce harsh ambient light. For example, you can set your camera up to expose for the background perfectly.
This truly dramatic lighting is best for headshots or stage photography. When using flash for outdoor photography, the sun will probably cause harsh lighting. With an 8:1 ratio, there will be about eight times more light hitting the brighter part of the subject's face than the shadow part of their face.

Solid state batteries are advanced energy storage devices that use solid electrolytes instead of liquid ones. This design enhances performance, safety, and efficiency by minimizing issues like leakage or combustion commonly found in traditional lithium-ion batteries.
Solid-state batteries operate similarly to traditional lithium-ion batteries. The main innovation lies in the use of a solid electrolyte, which replaces the liquid electrolyte and separator found in traditional lithium-ion batteries, with a solid material such as ceramics or polymers.
A solid-state battery (SSB) is an electrical battery that uses a solid electrolyte for ionic conductions between the electrodes, instead of the liquid or gel polymer electrolytes found in conventional batteries. Solid-state batteries theoretically offer much higher energy density than the typical lithium-ion or lithium polymer batteries.
Solid-state batteries can use metallic lithium for the anode and oxides or sulfides for the cathode, increasing energy density. The solid electrolyte acts as an ideal separator that allows only lithium ions to pass through.
However, the manufacturing process of the solid-state battery is not yet completed with a finished elementary cell. Figure 2 gives an overview of the remaining process until a cell ready for sale exists at the end. First, the elementary cell is cut to the respective cell size. A laser is usually used for this purpose .
The production of individual battery components (cathode and electrolyte / separator) on a small scale for material evaluation is carried out by means of automatic film applicator and doctor blade technology. The different widths and film thicknesses are realized using different doctor blades.
This article provides an overview. The transition from prototype cells to mass production is one of the challenges that must be solved to help the solid-state battery achieve a breakthrough.

[PDF Version]Battery regulation's summary in the top countries producing electric vehicles - the EU, the US, China, South Korea, and Japan.
BRUSSELS, Nov 28 (Reuters) - France, Germany and Sweden called on the incoming European Commission on Thursday to ensure the future of battery production in Europe and avoid relying on China to meet its needs for the green transition.
The European Union's new battery regulations represent an ambitious effort to regulate the full lifecycle of global battery production. However, questions have been raised about their ability to regulate the social and environmental performance of mining and battery manufacturers.
This strategic move is tailored to ensure seamless battery trade relations between China and the EU. It's pivotal to note China's overwhelming presence in the battery production landscape, holding a staggering 77% of the global market share.
These new guidelines introduce significant changes poised to impact battery producers across the globe, with companies in China and Taiwan being at the forefront of these challenges. Key Highlights of the New Regulations: Beginning in 2027, any power batteries destined for European markets will mandatorily require a "Battery Passport."
China is one of the economies making significant advances in the battery and EVs sectors. China also controls some of the most critical mineral supply chains. China has active regulation for recycling, including a regulation on battery recycling first introduced in 2018.
Lithium-ion batteries (LIBs) have become one of the main energy storage solutions in modern society. The research on LIB materials has scored tremendous achievements.
With the rapid development of new energy vehicles and electrochemical energy storage, the demand for lithium-ion batteries has witnessed a significant surge. The expansion of the battery manufacturing scale necessitates an increased focus on manufacturing quality and efficiency.
While the performance of lithium batteries has increased tremendously, there's still room for improvement to lower cost, increase sustainability and maximise their impact on decarbonisation, says Marcos Ierides, consultant and materials expert at innovation consultancy Bax & Company.
For these solutions to reach their full potential, they need to be coupled with efficient energy storage technologies. The performance of lithium-ion (Li-ion) batteries has increased tremendously as a result of significant investments in R&D; energy density has tripled since 2008, while cost has reduced by close to 85%.
Fig. 1 shows the current mainstream manufacturing process of lithium-ion batteries, including three main parts: electrode manufacturing, cell assembly, and cell finishing .
The current research on manufacturing data for lithium-ion batteries is still limited, and there is an urgent need for production chains to utilize data to address existing pain points and issues.
The manufacturing data of lithium-ion batteries comprises the process parameters for each manufacturing step, the detection data collected at various stages of production, and the performance parameters of the battery [25, 26].
These studies anticipate a wide cost range from 20 US$/kWh to 750 US$/kWh by 2030, highlighting the variability in expert forecasts due to factors such as group size of interviewees, expertise, evolving battery technology, production advancements, and material price fluctuations. However, it's worth noting that this approach does not.
Battery production cost models are critical for evaluating the cost competitiveness of different cell geometries, chemistries, and production processes. To address this need, we present a detailed bottom-up approach for calculating the full cost, marginal cost, and levelized cost of various battery production methods.
Battery production cost models are critical for evaluating cost competitiveness but frequently lack transparency and standardization. A bottom-up approach for calculating the full cost, marginal cost, and levelized cost of various battery production methods is proposed, enriched by a browser-based modular user tool.
It calculates battery cell and pack costs for different cell chemistries under a specified production volume within a pre-defined factory layout and production process. The model is frequently used, adapted, or extended by various authors 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18.
The article identifies main cost types for battery production as land acquisition, construction, equipment, liability, material, utilities, logistics, and labor. The comparison is based on 18650-cells with a NMC cathode chemistry. The work identifies a gap inside the labor costs between the two countries.
By discussing different cell cost impacts, our study supports the understanding of the cost structure of a lithium-ion battery cell and confirms the model's applicability. Based on our calculation, we also identify the material prices as a crucial cost factor, posing a major share of the overall cell cost.
As battery cost accounting lacks standards, previous cost calculations widely differ in how they calculate costs and what they classify as costs. By discussing different cell cost impacts, our study supports the understanding of the cost structure of a lithium-ion battery cell and confirms the model's applicability.
